The Price of Solar Batteries In Sydney: The Cost Of Installing Solar Battery Storage

Solar storage has taken off over the last 2 years, to the point where we are now installing nearly all of our systems with either integrated battery storage or as a battery ready solar system.

The price of solar batteries in Sydney depends mainly on how much capacity you want as well as any additional features such as backup for when the grid is down.

The Price of Solar Batteries In Sydney: The Cost Of Installing Solar Battery Storage

solar power installer newcastleSolar storage has taken off over the last 2 years, to the point where we are now installing nearly all of our systems with either integrated battery storage or as a battery ready solar system. The price of solar batteries in Sydney depends mainly on how much capacity you want as well as any additional features such as backup for when the grid is down.

Households with lower energy usage and a solar system smaller than 5kW are often well suited to Enphase batteriesAn Enphase Storage System starts at a little over $5000 fully installed, or around $105 a month for 5 years.

Smaller battery systems are designed to store power during the day to use in the evening, and typically don’t include backup functionality.

For larger households with at least a 5kW solar system, Powerwall from Tesla will be a better fit. Larger solar batteries start at around $12,500 – $14,000 fully installed depending on functionality and capacity, or around $250 a month over 5-years.

Remember, solar batteries capture excess solar power so you should be generating at least 8-13 kWh of excess solar power a day to charge a larger solar battery. Larger batteries are ideal for maximising self-sufficiency, reducing your household’s reliance on coal & gas, protecting your home when the grid goes down and aiming to run your home on solar power 24/7.

With a capacity of 13.5 kWh, Powerwall has sufficient capacity to power most households through the evening hours. Tesla Energy provides a 10-year workmanship warranty and like all warranties serviced by Solaray, we offer full support and free full-replacement service as a part of our Platinum Service Package. This extra support is what sets Solaray apart and why thousands of households across Australia have trusted Solaray for their solar and storage installations.

Living Without Power Bills

Solaray customer Angela has been living easy now that powering her home is entirely free.

For the last year, Angela’s home has been 96% powered by solar panels and a Solaray Energy installed Tesla Powerwall home battery.

Powering the home in 2018 used to cost Angela $2400, but in the months after combining her solar panels with a new Tesla Powerwall home battery, Angela’s power bill has dropped to below $0. This means her power retailer is, in fact, giving her a credit every quarter for the energy she’s contributed back to the grid.

“My power bill used to be $600 per quarter, the last bill I got was a credit of $40. I’m sure the next bill will be even better since it’s summer.” Read Angela’s story here…

How Solar Storage Reduces Your Power Bills

Solaray Energy Tesla Powerwall 2 SolarEdge Installation ProfessionalThe price of lithium batteries continues to fall, making backup storage an affordable option for many households in Australia.

The feed-in tariff for selling excess solar power back to the grid is very low in many states of Australia. In Australia, we typically get a credit on our power bill of between around 10 and 12 cents a kWh. By storing this excess solar power in batteries, we can use it during the peak billing period where prices can be over 50 cents a kWh. This is known as maximising self-consumption of solar power and is a great way to reduce your power bill. Many Solaray customers are now running their home almost entirely on solar power!

Energy prices continue to rise. Even if you get a discount from your energy retailer, power prices in Australia are amounts the highest in the developed world, in some cases more than double the price for energy compared to nations such as Sweden and Finland. Nationally, prices are up more than 120% over the last 10 years, and this trend is expected to continue for the foreseeable future. By installing solar with battery storage you can lock in your power prices for the next 25 years by generating most of your own power using solar (Rolfe 2016).

Australia is still mainly powered by coal. Australian households are leading the world with our uptake of residential solar power with 1.5 million systems installed, however the same cannot be said for government and big business. Most of the power generated in Australia still comes from coal, and there is reluctance in Canberra to transition to renewables. The biggest vote we have as consumers is to lead the way, installing solar power with backup storage to run our homes almost entirely on solar power. By installing a 5kW system, we take around $50,000 off the books of the coal industry and directly invest in the growing renewables industry.

Solar storage systems include revolutionary energy management technology that automatically directs solar power into your home or to recharge your batteries. Online consumption monitoring allows you to monitor how much power you are using in the home as well as how much solar power your system is generating.

Exciting home automation is on the way, which will allow you to send excess solar power into appliances such as to automatically turn on the pool pumps, air conditioner or underfloor heating. All of this will be able to be controlled from a mobile phone, allowing you to take back control of your power consumption.

EV charging is around the corner. Installing a solar power system will allow you to charge your electric car from excess solar power, and it may even allow you to charge your home batteries from excess capacity in the car’s battery.

The power grid is struggling to generate enough capacity on hot days, causing highly-publicised and disruptive blackouts in SA and around Australia. By installing solar storage, you can continue to run essential appliances such as your freezer, the internet and perhaps a few lights.

Tesla Powerwall Optimised By Evergen

Evergen Tesla PowerwallAll Tesla Powerwall systems installed by Solaray are optimised by Evergen. Evergen Intelligent Control Software optimises your solar & storage system to save you an additional 26.4% on average on your power bills.

Evergen can further reduce your power bill using an advanced algorithm that includes 42 different data points:

Weather Forecast: Evergen predicts your solar output to ensure your battery is adequately charged during wet weather.

Your usage patterns: Over time Evergen uses machine learning to predict how much power you use, and when. For example, if you need more power on certain evenings, Evergen will make sure your battery is fully charged for when you need it.

Tariff Awareness: If you are on time-of-use tariffs, Evergen will make sure you use as little grid power as possible during the peak billing period. It can even charge your battery overnight during the off-peak tariff if you need it or if wet weather is forecast for the coming days.

System Health: You no longer need to worry about the performance of your system. Evergen not only keeps track of system performance, it actively works to maximise the performance and longevity of your battery.

Intelligence data is also available through the app such as how much money you are saving and your solar generation. Daily monitoring by Evergen helps you to:

  • Save even more from your solar generation
  • Store and resell excess energy generated by your solar panels
  • Use your solar energy even when the sun goes down
  • Keep the power on even during a blackout with backup power
