Solar & Storage FAQs: Your Questions Answered

Sydney’s Best Prices, Full Customer Support & Free Online Monitoring A 10kW Solar system in Sydney is becoming a popular system size for larger households and businesses as solar power prices continue to fall and significant government rebates remain in place. The price of a good-quality 10kW system with a Sungrow inverter has fallen dramatically in recent years to under $9,000 fully installed. There are a number of factors that need to be considered when installing a 10kW solar system, and installation costs can vary considerably. A large house, shed or barn roof will have very few if any additional installation costs, whereas some homes will have detailed roofs where panels need to be installed across multiple roof sections. In this case we recommend Enphase Microinverters where each panel operates independently of the others. As a rough guide, 10kW systems start at under $9,000, (repayments are available using a Low-Interest Green Loan) for a good quality inverter such as the new ADA model from Sungrow, with premium panels such as Trina Vertex Modules and a straightforward installation. A top-of-the-range system using Enphase Micro Inverter will start at roughly $12,500-$13,000, and maybe a little more depending on the site. We are now selling most of our solar systems using Enphase Micro-Inverters with panel-level output and monitoring. These systems can significantly increase output on shaded roofs but are certainly not limited to unfavourable conditions. Find out more: The Benefits of Enphase Microinverters vs. String Inverters, Even on an Unshaded Roof. There are also situations where we need to maximise output using a restricted roof area. In this case, we will need to use high-efficiency panels such as the 1KOMMA5 420W all-black panels. This will increase the initial outlay but will maximise returns over the life of the system. 10kW Solar System Details 10kW Panel Array: as few as 24 x 420W 1KOMMA5 panels. Inverter: 10kW with a maximum of 2 strings, SolarEdge, or 1 x Enphase Micro Inverter per panel for maximum performance Mounting Kit: Solaray can design a mounting solution for almost all roof types. The two main exclusions are asbestos and slate roofs. Estimated output: 14,235 kWh per year, or an average of 39 kWh a day. Energy Cost Reduction: Multiply expected output by the cost of power per kWh to see how much you could save if you use all of the solar power that is generated. This figure can be up to approximately $4,400 per year and will change depending on the price you pay for electricity. Talk to the Solaray Team today for personalised advice and performance guidelines. With a possible return on investment of between 3 – 5 years, a 10kW solar power solution is now an attractive investment option for your home or business to significantly reduce your power bills and to run your home or business on renewable energy. Request A Personalised 10kW Quote: We are Sydney’s Leading Solar Power Installer 10kW Solar System Output According to the Clean Energy Council Guidelines, A 10kW solar system in Sydney will output around 39 kWh a day (averaged out across the year), outputting more on the long summer days, and less in winter. It is important to understand that this 39 kWh of solar power will be produced during daylight hours, and typically as a bell curve as illustrated below. Depending on how much power you use during the day, typically you would want to have a quarterly power bill of over $1000 (at least approx. 40 kWh a day excluding any off-peak hot water) to make good use of a 10kW system. A solar system will peak when the sun is shining directly onto the panels, so for an array facing north, this will be for approximately 4 hours during the middle of the day. You can see in the graph how shade from clouds immediately results in a drop off of solar power, and that in summer the system will continue operating until 7 pm if you have the panels installed to catch the late afternoon sun. The most important point to take away from this example is that a 10kW system will almost never reach its peak output. For that to happen, it has to be the right time of the day, the right time of the year, clear skies and not too hot. In this example, the system is installed on a tin roof with a very slight pitch of about 5 degrees. In Sydney, panels that are installed flat will be working at their peak efficiency during summer because the sun is so high in the sky. We recommend that for larger systems the panel array is split into two strings of panels. The most popular option is to have one string of panels facing north and the other west of north. This helps distribute the output into the afternoon, making it easier to use more of the solar power as it is generated. This is especially important for households with time-of-use billing, when the cost of power during the peak billing period of 2 pm to 8 pm can be up over 50 cents a kWh.

Is solar power worth it in Australia? It’s a question we get asked dozens of times a day and for most households, installing solar panels is worth it.

How Does Solar Power Reduce Your Power Bill? I nearly got myself into trouble this week. A customer asked me how much cheaper his quarterly power bill would be after his solar feed-in tariff. My answer was: “around $20... $30 if you are really unlucky.” Luckily he didn’t hang up! He asked: “So you expect me to pay thousands of dollars for a solar system to save $30 a quarter?” Not quite... A number of people new to solar power get confused by feed-in tariffs and where the real benefit of solar power lies. So let’s break down how solar power reduces your power bill and why getting a large solar credit on your power bill is actually not the best result. Please keep in mind that these numbers are an example of what is possible with solar power. Your situation will almost certainly be different, which is why we recommend you call the Solaray Team for personalised advice before deciding on a solar power system. How residential solar power works Solar power is fed into the home as it is generated and is used first before you draw power from the grid. This means that for every kWh of solar power used in the home you are directly reducing your power bill by the amount you would have otherwise paid for the electricity. This reduction in your power bill is the main financial benefit of solar power. The cost of electricity varies from house to house, and many households are now on time of use billing as illustrated below: Time-of-use billing If you have time-of-use billing, take the average of your peak and shoulder rates to roughly estimate how much solar power will save you. You can ignore the off-peak tariff as solar power doesn’t work during these hours (10 pm to 7 am). We estimate that on average solar will save you around 25-30 cents a kWh. Flat rate billing If you pay a flat rate for your power, this is the amount of money solar will save you for every kWh used in the home. Typically the rate in Sydney is around 22 to 28 cents a kWh, plus GST. If the solar power isn’t used in the home it is automatically fed out to the grid and you may be paid a feed-in tariff by your energy retailer. Typically this feed-in tariff is around 6-10 cents a kWh, so it is important to shop around and find the best deal. It quickly becomes apparent that saving up to 30 cents a kWh is a better deal than making 6 cents a kWh from your feed-in tariff. How Solar Power Reduces Your Power Bill: A 10kW Solar System Example As an example, Tom installed a 10kW solar system in Sydney on a north-facing roof. On average, the system produces 40kWh of solar power every day (averaged out across the year, doing more in summer and less in winter): Although Tom works during the day, he is able to use 20kWh of power during the day without too much trouble. Firstly the base load of his house runs on solar power, with appliances such as the fridge, freezer and a few lights remaining on all day. Tom also turns the dishwasher on when walking out the door and sets the washing machine on a timer to run at 1 pm. During summer the pool pump automatically runs during daylight hours on solar power. Tom pays a flat rate of 30 cents a kWh for his power including GST. This means that on an average day Tom saves $6 off his power bill (20kWh x 30 cents). Over a standard 91-day quarter, this equates to approximately $550, not bad considering he only uses 50% of the solar power generated. It is important to note that this reduction is not recorded on the bill, the bill is simply cheaper. So if Tom normally pays $800 a quarter, the new bill will come in at $250. The remaining 20kWh that are not used in the home are paid as a credit. In Tom’s case, he is paid a feed-in tariff of 10 cents a kWh, which on average is $2 a day (20kWh x 10 cents) or $181 a quarter. This means that the $250 bill is reduced to $68, and this reduction is recorded on the bill as a ‘solar buyback.' So an $800 bill is reduced to $68. Not bad! This is an example of how buying an 'oversized solar system' can make a huge impact on your power bill. It involves actively managing your power consumption to ensure most of your usage is during the daytime. It is also a lot more effective if you have time-of-use billing because any power you use at night is a lot cheaper as it is during the off-peak billing period. We typically aim for our customers to use 70% or more of the solar power if the solar system isn't oversized. A Final Word about System Sizes Of course, all of the above information assumes that you won’t be adding battery storage later. To keep it simple, we have not included the impact batteries will have on your power bill or the recommended system size - this gets a little more complicated because there are a few different strategies we can recommend based on when you use electricity, your roof space and your budget. Again, it is worth talking with one of our solar and storage experts about how to factor this in:

Why are the prices for solar systems so different? Why are my solar quotes so different? The world of solar presents many challenges for the everyday Australian who is trying to choose the right solar system for them. You see copious TV or Facebook ads for a 6.6kW system for a stupidly low price, but then get a quote from another supplier that is three or four times the price for what appears to be the “same” system. You find yourself wondering how on earth the price differences could be so dramatic and feeling unsure of which installer you should go with. The systems appear the same, so why would you pay more when you can pay less? The reality is, there are really only a few key elements when it comes to selling solar systems. The quality of the products being used The quality of the workmanship of the installation The cost of running the business What does this mean? The cheaper a system is, the more corners that are being cut on one (or all) of the above measures to be able to make it that price. Let’s look at each component in more detail. Product quality There is no escaping the fact that the quality of the products being installed can have a massive impact on the cost of the system.  Side Note: The type of product can also have a significant impact on the cost. For example, N-type vs P-type solar modules, or string inverters vs DC Optimisers vs microinverters. All come with a price (and performance) difference. But within each type of product, there are multiple brands playing in that space which can also vary in quality and price. This article is focused on how quotes of similar product types can vary. With the growing demand for renewables, there has been a lot of new manufacturers entering (and exiting) the industry over the last ten years or so. This is why it is important to do your homework on the brands and products that you are getting quotes for.   We suggest you research the following: Who owns them? Where are they based for manufacturing? Do they have an actual Australian office with local staff? How long have they been operating (in total and in Australia)? How long is the product warranty? What is their performance warranty? (look at both length of time and warranted product performance) By researching the above, you will be better prepared to make an informed decision about the quality of the company whose products you are having quoted. BLOG POST: Cheap Solar: An Incredible 1 in 5 Solar Systems are Dodgy Workmanship Quality (a.k.a. Quality Solar Retailer) ‘A solar system is only as good as the person installing it.’ This phrase is a cliché in our industry for a reason. Cheap products that are properly installed could absolutely outperform quality products that are improperly installed. The last thing that you want is someone who isn’t skilled and qualified, slapping panels on your roof without giving it the care and attention required to ensure that it will perform as expected, and most importantly, that it is safe. Given that your solar system is going to sit on your roof for years and hopefully decades to come, it is absolutely worth the time, effort and money to ensure that you are getting both quality products AND quality installers. The cost of quality tradespeople is higher than the cost of hiring unskilled workers. Lots of less reputable companies will cut corners on workmanship in any way they can. When you see ridiculously cheap solar system prices, chances are they are using cheap workers (and probably cheap products as well) to undertake the installation. Whilst you might be saving money now, if your system has to be replaced down the track much sooner than planned, you will lose your original investment altogether.  Did you know? In 2018, the Clean Energy Council suspended 160 solar installers and cancelled the accreditation of 12 installers and struck more than 5,500 models of solar panels off its list of approved products. The Clean Energy Regulator inspected 1.2% of installations, and found that 1 in 6 of installations was substandard and 1 in 30 was unsafe. When getting a solar quote, it is important to do your homework on the solar retailer as well. Things to check for include: Do they have a physical Australian office? How long have they been in business? Are they a Clean Energy Council (CEC) Approved Solar Retailer? What workmanship warranty do they offer? (CEC Approved Solar Retailers are committed to providing a five-year warranty at minimum) How long have their installation teams been working with them? Do they have an in-house service team? Business Costs We all know that running a business isn’t cheap.  There are a number of overhead costs that any quality solar retailer should be factoring into their quotes, including: Staff salaries (sales, operations, service, electricians, administration etc.) Rent for office and warehouse storage spaces Licensing and insurance fees Freight and logistics After-sales service (which is of particular benefit to you) You wouldn’t want your solar retailer going cheap on any of these, as it has a flow on effect on the work they do, the products they sell and the support they provide – all of which could end up costing you more. You want a business that is dedicating some of their costs towards the longevity of their business so that they are there to service your warranties if required. There are always opportunities for solar businesses to cut corners, but it is always you, the consumer, who assumes the risk and ultimately pays the price for these shortcuts. What is next? What should a system cost? All these factors will impact the price of your solar quote. This is why seemingly similar solar quotes can have wildly different prices attached to them. The next question someone typically asks us after asking why solar prices are so different

The Cost of Solar Power vs The Grid Solar power is significantly cheaper than buying power from the grid, and with generous government incentives available, solar power is a no-brainer for most Sydney households. Especially now that so many of us are spending more time at home. So let's get into the numbers... what is the real price of solar power vs the grid? Here are the considerations for working out the cost of solar power per kWh: System output over the life of the system System price Ongoing costs Solar system's Output: Daily output: According to the Clean Energy Council Guidelines, a solar power system in Sydney generates 3.9 kWh a day per kW. For example, a 10kW system will produce 39 kWh a day averaged out across the year (it will produce more power in summer and less in winter). We have found this figure to be conservative, but let’s stick to the guidelines for this example. The System's Life: REC Alpha Pure panels come with a 25-year performance warranty that states that after 25 years the panels will generate at least 92% of their original output. For example, a 405W panel will be producing 373W after 25 years. So in the first year, a 10 kW system might produce 14,200 kWh and in the 25th year, it may produce somewhere in the ballpark of 13,000 kWh. The Cost of a 10kW Solar System per kWh The price of a solar system varies depending on the quality of the products you buy, so let’s look at two options, using top-of-the-range REC solar panels with either a good-quality string inverter or Enphase Microinverters. As a ballpark figure, the string system will cost $13,000, plus the $2,000 for a new inverter/ repairs. If we expect the system to produce 337,770 kWh over 25 years, we have a cost of 4.4 cents per kWh! With the Enphase system, let’s go with a ballpark cost of $16,000 plus the $2,000 for repairs and replacements. Over 25 years, we have a cost of 5.3 cents per kWh Compare this to your power bill to see just how much cheaper it is!!! Due to the panel level output of Enphase systems, on average our Enphase systems output 110% of their expected performance. Therefore, you can expect to get significantly more output from your Enphase system than the Clean Energy Council Guidelines. This increase in output along with a significantly longer life expectancy means the cost of an Enphase system is approximately the same as a standard inverter per kWh over the life of the system. How does this compare to the cost of power from the grid? On average, a house in Sydney pays around 25 to 38 cents a kWh plus GST, and up to 52 cents between 2 pm and 8 pm if you have time-of-use billing. It quickly becomes apparent why solar power is so popular! It is many times cheaper than buying power from the grid. The biggest factor that affects your price per kWh is whether you are able to use the solar power in the home or whether you send it off to the grid. A typical feed-in tariff is now around 5-10 cents a kWh (this can vary a lot so it is important to find a good deal with an energy retailer). So even if you don't use some of your solar power, you are still able to generate it for around 5 cents per kWh and then sell it back to your energy retailer for a profit.

As solar system prices continue to fall, the average system being installed in Australia in 2023 is currently from around 5kW to 10kW. Despite this, a 3kW solar system can be a great system for a small to medium-sized home, either with limited roof space or low day-time energy consumption. The cost of a 3kW solar system varies a lot depending on the brands, with the price of a good quality solar system starting from around $4,500-$5,500 fully installed. A smart 3kW solar system powered by Enphase is around $300 more expensive, and we also recommend looking at high-efficiency solar panels from LG Solar. Talk to the Solaray Team today for more information and personalised pricing. A 3kW system typically has a 10-panel array and can save you up to around $300 a quarterly power bill if all of the solar power is used in the home. As solar prices continue to fall, it is now possible to get a return on your money in 4 to 5 years using top-quality brands! The Price of a 3kW Solar System As a price guide, a good quality 3kW solar system in Sydney will cost from around $4,500 for a simple installation, or around $85 a month over 5 years using good quality panels from China such as Trina Honey Modules, and a European-made inverter from SMA. Expect to pay up to around $5,000 to $7,000 for a 'smart solar system' including a top-of-the-range high-efficiency panel such as the REC Alpha Pure module and panel-level output using Enphase MicroInverters. This is after a government incentive of around $1500, and it is fully installed and connected to the grid. Our price is always a fully inclusive price, subject to confirmation by our system designers who will often need to conduct a site inspection. Over 80% of our installations now feature panel-level output, powered by Enphase. Of course, these prices will depend on a number of factors, which our solar team can confirm with you either over the phone or during a site inspection when required. This article will look at the benefits of installing a 3kW system, the main brands you should be looking at and provide detailed information to make sure this size system is the right fit for your household.     Is A 3kW Solar System Enough? For a few years now, we tend to only install a 3kW solar system if we are limited by roof space. For almost all households, a 3kW solar system will not be large enough to cover your home's energy usage. The average-sized solar system we are now installing is closer to 8kW, with most households choosing to install at least a 6kW system. We have had a few people tell us they are worried the solar industry is trying to up-sell them when they first enquire about a 3kW system. A good analogy would be to consider someone walking into a computer shop and asking for a computer that was a great option back in 2015. If the 2015 model was still available, but only a little bit cheaper, it isn't in the customers' best interest to buy the older computer. 3kW solar systems were common a few years back when solar was a lot more expensive, and when panels were a lot less efficient. Not only has the price per panel plummeted in recent years, but the efficiency of the panels has also improved significantly. The standard residential panel has increased from 250W to 415W, while the price per panel has fallen. In fact, the price of solar per kWh generated by a solar system is actually cheaper than the feed-in tariff offered by most energy retailers. This has resulted in a huge shift in the systems people are buying to the point where a lot of our customers are literally filling their roofs with panels. Other reasons why solar systems are now much larger than 3kW: The larger the system, the larger the government rebate. This means that the increase in price for the larger system is partially offset by the government incentive that comes directly off the purchase price Many households are planning to buy a plug-in hybrid or electric car within the next 10 years. Having a larger solar system means excess solar power can be used to charge the car during the daytime Battery storage is now the norm, and most households will have battery storage as a part of their solar system in the coming years. Ensuring the solar system is sized to your 24-hour usage ensures the system is battery-ready The Output of a 3kW Solar System According to the Clean Energy Council Guidelines, A 3kW solar system in Sydney will output around 12 kWh a day (averaged out across the year), outputting more on the long summer days, and less in winter. It is important to understand that this 12 kWh of solar power will be produced during daylight hours, and typically as a bell curve as illustrated below. Depending on how much power you use during the day, typically you would want to have a quarterly power bill of around $400 to $600 (approx. 24 kWh a day excluding any off-peak hot water) to make good use of a 3kW system. A solar system will peak when the sun is shining directly onto the panels, so for an array facing north, this will be for approximately 4 hours during the middle of the day. You can see in the graph how shade from clouds immediately results in a drop off of solar power, and that in summer the system will continue operating until nearly 8 pm if you have the panels installed to catch the late afternoon sun. An important point to take away from this image is that a 3kW system will almost never reach its peak output. For that to happen, it has to be the right time of the day and the right time of the year. In this example, the

We are increasingly being asked to supply and install 72 cell solar panels for residential customers. Firstly, a quick summary of the differences between a 60 cell and a 72 cell panel. The difference is as simple as it sounds – a 72 cell panel has an extra row of 12 cells which mean the output is increased without any increase in efficiency. The panel is simply bigger. The increase in output per panel is achieved by making the panel bigger, not more efficient (in fact they are usually marginally less efficient). As a result, the 72 cell panels are much larger (2m x 1m instead of around 1.65m x 0.95m), much heavier (around 28kg vs around 20kg), and in most cases require different mounting than standard panels. These 72 cell panels should not be confused with the high-efficiency panels from manufacturers such as LG Solar, which now actually have 120 cells instead of 60 as the cells have been divided to further increase output from a standard panel design. Most of the 72 Cell panels on the market today are designed for commercial or utility-grade installations where they are transported in bulk, lifted onto rooftops by crane rather than by hand and are normally required to be installed flat because there is little or no requirement for wind resistance. When comparing one of the leading manufacturer’s 60 cell and 72 cell panels, there are small (but material) differences in the positive tolerance levels, efficiency and temperature coefficient – and a significantly reduced level of hail resistance. Perhaps this is getting a bit technical but it makes a big difference to the long-term reliability of panels in a residential setting. The main issue with 72-cell solar panels is that they are not designed for residential use. In particular, they are not structurally designed to be manhandled individually and so the possibility of flexing the panels whilst being carried and installed on a rooftop may reduce the long-term viability of the backing sheet (and therefore the entire panel) as microcracks may not show up for months or even years after an installation. Another factor is that they usually require a different mounting system (3 rails rather than 2) and different engineering certificates from the mounting manufacturer. But... they are cheaper! Yes, and the reason they are cheaper is that they are often manufactured to a different standard than residential panels, plus they are bought in bulk so a lot of the time people are looking at the wholesale prices they've found on the internet somewhere rather than looking at the price of what it costs to buy 10 or 20 panels as a part of a fully installed system. If you want to install panels with a higher output (or if you just want the best available), instead of trying to install a commercial-style panel on your roof, you should consider the LG NeON panels, considered the best panel available in Australia.

In Australia, solar panels will generate the most energy over the course of a year when they are facing north. This is especially important in winter when the sun is lower in the northern sky. Technically, the panels should be tilted north to match the angle of the sun, however tilting panels basically just pushes output from summer to winter, so if you have a flat roof and you use more power during summer it actually makes more sense to leave the panels close to flat with just a little tilt to ensure that rain flows off the panels and doesn't pool on the surface. If you have a pitched roof, then we will always install the panels in line with the roof. If your house has a north-south roofline with the option of installing the panels east or west, we can install panels on either roof section depending on what time of the day you use the most power. Many families will use more power in the afternoon when the kids are home from school and the air conditioner and pool pump are running. If this is the case we would recommend installing your solar panels on the western roof, or we could do a split system with most of the panels west and a few east. We can split your array by using Enphase microinverters. This can also help avoid shade later in the afternoon as pictured below. You can see in this image we are using 3 sections of roof where each string of panels will output power at different times across the day. By splitting the panels like this, the output of solar power gets distributed across the day, making it easier to use more of the solar power because there isn't such a big peak in the middle of the day: The other point that can influence the decision of where to install panels is that time-of-use tariffs can sometimes be charged by your energy retailer (ask us for help if you are not sure about this). This typically will only apply to households in the Ausgrid distribution area (roughly the eastern half of Sydney): A solar system will peak when the sun is shining directly onto the panels, so for an array facing north, this will be for approximately 4 hours during the middle of the day. The graph below shows a system that is installed on a roof facing north-west where there is a bit of early morning shade. This is a great orientation for a solar system in Sydney, especially if you have time-of-use billing where power is most expensive after 2pm on weekdays in summer. You can see in the graph how even in autumn the system will continue operating until 7 pm if you have the panels installed on a roof that catches the late afternoon sun: The other important point to take away from this image is that a 5kW system will almost never reach its peak output. This system reached a maximum output of 3.84 kW and yet produced 29.1 kWh of power across the day: For a 5kW system to output close to 5kWs at any one time, it has to be the right time of the day and the right time of the year, which is very rare. In this example, the system is installed on a tile roof with a normal pitch of about 20 degrees. There are 19 panels all facing north-west. This helps extend the output into the late afternoon, as seen in the graph above. In Sydney during summer, panels that are installed flat will be working closer to their peak efficiency because the sun is so high in the sky. The peak output on this system during a sunny March day is only 3.84 kW, however, even in March, this 5kW system will typically produce around 30 kWh a day, much higher than the Clean Energy Council guideline of 19.5 kWh.

No, in Australia a solar system without integrated battery storage turns off in a blackout. There are two reasons why your solar system turns off when the grid goes down: Safety: during a power outage, repair crews will be working to fix the grid to get power restored. To avoid endangering them, it is essential that there is no power flowing from solar systems out into the grid. Technical: the appliances in your home need a steady flow of electricity to work properly. In many cases, appliances can also be damaged if the flow of power isn't steady and constant. Because a solar system doesn't produce a steady flow of power, the system needs to be turned off when the grid goes down. For these two reasons, your solar system must automatically shut down in the event of a blackout, unless you have battery storage with backup. Battery Storage With Blackout Protection Tesla Powerwall is the battery we recommend for households that want blackout protection. As a part of our installation service, we will work with you to nominate circuits that can be powered from your battery in the event of a blackout. Typically this will include things like a modem, lights, small pumps, garage doors and other appliances that are of high priority. Anything that uses a lot of power is typically not backed up in a blackout such as air conditioning and pool pumps. The final step is to nominate how much capacity you want to leave in your battery in case of a blackout. If you choose 30%, for example, your Powerwall will never discharge more than 70% of the battery's capacity, ensuring that in a worst-case scenario, you still have 30% of the Powerwall's capacity to get you through the night. In the morning, the solar system will start generating power again and the Powerwall will recharge from the solar power being generated.

What Does A 5kW Solar System Look Like A 5kW solar system in 2021 will typically have around 14-16 solar panels. With 330W panels we would use 16 panels, for the high-efficiency panels rated at 370W, we would use 14 panels which would give you will have a 5.18kW system. The panels are 1.7m by 1m, and for a 5kW system, we typically install the panels in 2 rows of 7 or 8 panels. A 5kW solar system will typically look like the image below once it is installed on your roof, using high-efficiency panels from LG. This is the NeON 2 panel from LG: In this 5kW installation, we are using the new Split-Cell panels from Trina Solar, so there are actually two rows of panels here, not 4: For more information about a 5kW solar system, click here: Everything you need to know about a 5kW Solar System
