Top 4 Reasons Why You Should Install Solar Panels NOW
FAQ
Yes. All installations under 100kW (and systems with an annual electricity output of less than 250MWh) are eligible for Small-scale Technology Certificates, or STCs for short. You’re eligible for STCs whether you’ve previously accessed a rebate or not. It’s also not means-tested and is accessible by everyone. The solar PV system or product you purchase in order to receive STCs must adhere to the Clean Energy Council (CEC) design and install guidelines, only use panels and inverters on the CEC approved list, comply with the relevant standards (like AS 4777), and be installed by a CEC accredited installer. In addition to STCs, your state may offer an additional rebate or program. These rebates differ between regions, so it’s worthwhile investigating what solar rebates apply in your area.
In most cases, we can make an effective system using the space available. However, it doesn’t hurt to set aside some space on the north-facing roof for at least 12 panels. A common panel these days tends to be 1.7 m x 1.0 m, so a little over 20m² for 12 panels will give you over 3 kW. However, if you want more panels and a larger system, you will need additional roof space. You’ll only lose approximately 15% of energy yield if panels are installed on the east or west (compared to north-facing panels), so we often incorporate these aspects too to make the most of the roof space you have available.
It’s often difficult to size a system on a new build as there’s no history of power usage. For this reason, we usually stick to common sizes like 3.5 kW and 6.5 kW. Note that for a single storey home, it’s just as easy to install after the build is complete. For two-storey installations we advise that you consult with us directly as it may be advantageous to complete some of the work during the build.
The main difference between a normal electrician and Sydney level 2 electrician is the level of training and the license they hold. Level 2 electricians are more trained to handle not only repair and maintenance but also do installations.
Solar panel installation requires experience with high-voltage wiring and isn’t for novices. In serious cases, incorrectly wiring your solar panels could cause a power surge, blow your inverter, and potentially start a fire. In most states, a certification is required before installing this kind of electrical work.
Aside from issues arising from your installation, studies have shown that the most likely fault you’ll have with your solar PV system will be with your inverter. This means that proven reliability is paramount if solar is a long term investment for you and your home and the most assured way you’ll get this is with a better inverter.
Reliability is not determined by your inverter warranty. Many customers have been stranded by manufacturers who had poorly designed inverters, the failures (and costs) of which they couldn’t support and so they soon disappeared from the solar market. Some manufacturers have even been known to offer extended warranties as a way of enticing a purchase, however, these are of no value to the homeowner when the manufacturer is no longer operating to honour them. Manufacturers who have been in the market for a long time (e.g. Fronius) have clearly demonstrated their products are reliable and have shown they will be there to support future warranty claims or issues.
Better inverters have a superior design thanks to their manufacturer’s experience. They generate more energy thanks to better algorithms in their MPPT and are both more efficient and less likely to fail. The online portals and apps that come with them are easier to use and offer greater functionality than those produced by less experienced manufacturers. In some cases, you can even add components like a smart meter to monitor energy consumption, hot water controllers and smart home devices to optimise self-consumption.
