SOLAR INSTALLATIONS
Why install
SOLAR
Installing solar has financial benefits
Many households want to know if their bill savings will be big enough to justify a solar electricity system.
The clearest answer to this can be found by working out the payback time of a proposed system, which is how long it takes for electricity bill savings to cover the installed system cost, and the annual bill saving, which shows the ongoing financial benefit after the payback period has been reached.

You should
ask about the maintenance and operation requirements of your system, and don

making a decision.
You could also search for a potential retailer or installer online

other consumers, or ask for references.
Things to know before
having a solar installation
Solar Savvy Tip
Tip: Always get at least three quotes from New Energy Tech Approved Sellers for the
same size system. Note that a quality system offering a long and useful life may cost more and be
more worthwhile.
Solar PV and battery retailers in the Solar Homes Program must fulfil our requirements, including
being a New Energy Tech (NET) Approved Seller.
This means they have committed to high standards across sales and marketing, quotes and
contracts, delivery and installation, and warranties and support. Customers doing business with a
NET Approved Seller can be confident they are getting clear, honest information, quality installation,
and good warranties.
Accredited installers
The person who installs your system also needs to be accredited under the Small-scale Renewable
Energy Scheme with
Solar Accreditation Australia, and must hold an unrestricted Class A Electrical
Licence registered with Energy Safe Victoria.
A good installer will help you plan the right system to suit your household now and into the future.
They will recommend the best position to install your system to generate as much electricity as
possible.
Why you need a good inverter
It is important to have a good inverter. In grid-connect systems, an inverter failure means your solar panels are doing nothing until the inverter is repaired or replaced. Still, it’s worth remembering that even the best inverter is unlikely to last as long as the rest of your system. Solar panels should last more than 25 years, but inverters are not generally expected to last much more than 10 or 15. You can expect to replace your inverter at least once over the life of your solar PV system.
Consider how system faults will be handled
A warranty is only as good as the company that provides it. If the company disappears in a few years,
you might have difficulty making a warranty claim should failures occur.
It’s not possible to know the
future of any solar panel manufacturer or installer, as some of the biggest players over the years
have simply disappeared.
Seeking out a retailer or installer with a long history in the business helps.
