Will my electricity bill go down once I get solar?
Yes, although your mileage will vary. Consistently using less power than your solar system produces is the best way to reduce your power bill.
When will my system be turned on?
As soon as the system is inspected, paperwork has been signed by customer and the meter has been changed and/ or reprogrammed.
Who inspects my system and who organises the inspection?
Your system needs to be inspected by an electrical inspector (VIC only). The inspection is organized by Sunwire and is included in the sale price of your system.
Does shading affect the performance of the panels?
Yes. Solar panels should ideally be in full sun from at least 9am to 3pm. Solar panels produce less power when they are shaded and should be situated where there will never be any shadows on them. If there is shading, Sunwire’s solar specialist will discuss your best options for maximum benefit.
Will my system store the power I generate but don’t use?
No. Grid–connected solar systems do not store electricity. Instead, any electricity you do not use in your home is exported into the electricity grid.
Does the power I generate get used in my property first or sent to the grid first?
The electricity from the solar power system will get used in your property first. Only the excess is fed back to the grid.
What is a feed-in tariff and how can I get one?
A feed-in tariff is a price that you will get paid for electricity you generate from sources such as solar power. The feed in tariff in Victoria is a net feed in tariff and only applies to the excess electricity that you export to the grid. All large retailers are required to offer their eligible customers both a standard and a premium feed in tariff. You can receive the feed in tariff by contacting your retailer once you have a solar power system installed with the correct metering in place.
What happens if the grid power goes out?
The system will automatically shut down with a power outage and will switch back on when power is restored. If your system does not switch on when the power is restored you can contact us on 03 9587 0791.
Will it cost money to change my meter over?
Yes. The Sunwire sale price excludes the meter change and grid connection. This cost varies from state to state depending on the energy provider and type of meter. To find out more information contact your energy provider.
What is the difference between a solar hot water system and solar PV system?
A solar hot water system uses the sun’s warmth to directly heat water.
A solar PV system converts sunlight into electricity for use in the home or to be fed into the electricity grid. The heat output from the sun is not important for the solar PV system but the amount of sunlight available is.
Warranties & Guarantee
All Solar PV panels are usually provided with a performance warranty that can last up to 25 years.
