Solar Power Installation – Your Questions Answered

Is it difficult to go solar?

We make going solar one of the easiest decisions you can make to help reduce your power bill and your carbon footprint. We take care of all the paperwork, including your grid connect application, claiming your rebate and arranging your installation. All you have to do is give us the go-ahead and we will do the rest.

How much roof space do I need?

2kW Solar SystemMost solar panels are all approximately 1.7 meters high by 1 meter wide. If you have a flat roof please allow a minimum of 2 meters per row to allow for additional shading from the panels after they are tilted.

As today’s solar panels are about 265W or higher, you should allow 4 panels per kW. For example, a 4kW system can be installed in 2 rows of 8 panels, allowing 1.7 meters for each row plus a little buffer, and 8 meters long. The panels in a row sit flush and they are just under a meter wide, so allowing one meter per panel works out to be quite accurate.

Our Solar Experts have the ability to draw proposed panel diagrams on the computer such as the one below. Because we use aerial maps that do not take into account the pitch of your roof, our estimates are not exact to the centimetre, but we can get pretty close! If it looks like a tight fit we will send an installer out before the installation day to confirm everything for you.

 What happens once I sign the paperwork?

Once you sign up for a Solaray Installation, we immediately submit your grid application to the relevant energy distributor. For systems up to 5kWs, this is a formality. For larger systems it can take a few days or more. Once we receive approval, your installation will be managed by our installation coordinator, who will welcome you to Solaray and book an installation date for you. This is generally booked within around two weeks and installation dates are available Monday to Friday, weather permitting.

We endeavour to have your system installed within 2-4 weeks unless you request us to hold for whatever reason. Due to our strict safety policy, we do not install solar systems when it rains. In the event of inclement weather, we will rebook your installation as soon as possible. We always work with your requests as we strongly recommend that someone be home on the day of installation.

What happens on the day of installation?

You will receive a confirmation of the installation on the day or two prior to the planned day. The installers will arrive on-site and meet with you to discuss the installation, confirm their plans (eg panel and inverter location, conduit paths etc) are all in line with your expectations, and answer any other questions you may have. They will install the panels on the roof, run cabling to the inverter, mount the inverter on the wall and connect it to your meter box. Finally, they will test the system, demonstrate it to you and check everything is to your satisfaction. You will be asked to sign some paperwork to do with the system and the STC (rebate) application. Sometime soon after the installation (usually about 3 to 10 days later), another electrician will replace your meter with the new digital meter.

Why choose a Solaray Installation?

Installing any product on your roof is a job that needs to be treated with care. At Solaray, we pride ourselves on the quality of installation and workmanship. The quality of the installation can potentially determine both the performance and the longevity of your system. We apply years of project and implementation experience to our installation process and we are proud to set the standard for the industry for quality installations. All Solaray installations include:
– installers are trained and supervised by our Operations Team to rigorous standards
– installers are Clean Energy Council Accredited
– installers have a track record of quality installations
– we do not contract installations to unknown or ‘cheap’ contractors
– installers are given enough time to complete every job properly
– all installations are planned using our industry-leading project management methodology
– customers are kept up to date and informed at every step of the process
– we pride ourselves on rarely if ever needing to go back to a job to fix problems

Should you decide to go ahead, we will lodge an application with your electricity distributor for the connection of your new system to the electricity grid. We then plan an installation date with you for once the connection is approved. Our customer service team will keep you up to date as to the progress with your application and the installation day. On the day of installation, our team will arrive and install the system. This usually takes around 5 to 8 hours depending on size and complexity. Once installed, we demonstrate the system to you and arrange for the connection to the electricity grid (and the installation of a new solar meter). Naturally, our teams always clean up after themselves and are available to answer any questions you may have. Finally, we take care of any paperwork required to benefit from any rebates and bonuses.

Do I need permission to install solar power

In NSW, there is an exemption in place for solar PV systems less than 10kw as long as they do not alter the roofline and are not on a Heritage-listed building or in a Heritage area. You should check with your local Council as we cannot be responsible for the local rules in your area, however, it is extremely rare for a residential system to need Council Approval.

What happens if my roof is damaged during the installation of the solar system?

We will repair any damage we do in the installation of your system, However, if you have roof tiles that are very old, it is likely that some of these will be damaged in the installation as the installers walk across the roof, and so we ask that you provide us with spare tiles if necessary. If you are concerned about the age of your roof, please discuss this with us first.

How does the mounting system work?

Seaforth Mounting KitWe have custom mounting kits depending on your roof. For tile roofs, we use brackets that fit between the rows of tiles and mount firmly onto the frame of your roof. We do not need to break or remove any tiles. For colourbond roofing, we take out the existing screws and replace them with strong stainless screws to ensure that the system is firmly mounted to the frame of your roof. Normally we only make one penetration through the roofing to run the D.C. cable, and this is fully waterproofed and guaranteed. For Kliplok we generally do not penetrate the roofing because doing so voids your warranty. Because of this, we use special clips that grip the ridge of the Kliplok to hold the panels firmly in place.

We then mount 2 rails per row of panels and then the panels are mounted to the rails. This results in the panels sitting slightly off your roof. For more information please view our installation photos.

What angle do you tilt panels to on a flat roof?

solar panels wind damageOur main concern when our installers answer this question is your roof’s exposure to strong winds. Wind can create a vortex as it travels over tilted panels and it can literally pull the roof off your house, using the same force that allows QF1 to take off from Sydney Airport. Because of this we generally tilt panels between 5 to 10 degrees, and more detailed information is available here: Should I get tilt frames for my solar system?

Do I need to tell my neighbours?

No, you don’t need to inform your neighbours. Furthermore, solar panels are designed to minimise reflection so that as much of the sunlight as possible makes it through the glass to hit the solar cells. Depending on how friendly you are with your neighbours, you may want to knock on their door and explain this to them if you are installing panels close to their windows.

    I have a 3 kilo watt system already, is it possible to get a 5 kilo watt installed and add that to my existing system?
    I was told that you cannot do this.
    Is this correct information that I was told?
