If you have already decided to switch to solar power but are unsure how to find the best solar panel installer in Melbourne, this article is for you. Choosing the best solar panel installer can be the most challenging part of the solar buying process. Here is our checklist of critical factors before you make the big investment.
How Much Do Solar Panels Cost in Victoria?
When looking for solar power for your home or business, you need to ensure that you pay the right price for it. An entire system of solar panels can be priced forbiddingly high (for instance, quotes of $12,000+ after STC incentives for a standard 6kW system) or dangerously low where the cheapest parts and sub-contractors are involved ($5,000 or less for a 6kW system after incentives).
Beware of "Too-Good-To-Be-True" Quotes
Extremely cheap prices are derived by compromising on the quality of solar panels, inverters, and electrical components like DC isolators and cabling. If budget installers use recognized panel brands, they often cut corners on installation craftsmanship and safety gear.
Sharing an example of a poorly installed solar panel system near Tarneit, Victoria: our team was installing a commercial solar system on an adjoining plot when we noticed a residential DC isolator had completely burnt off, rendering half their system non-functional. The homeowners were blissfully unaware. A fire of that magnitude could have compromised their roof in dry weather, and it didn't even report an error back to the user.
"Our advice to you is simple: focus on the long-term value and reliability you are getting for the price quoted, rather than chasing the rock-bottom quote."
What are the Most Reliable Solar Panel Warranties?
Most people consider a solar system as one single product, when in fact solar installers purchase various components from multiple manufacturers and assemble them to create your bespoke system. When selecting an installer, verify the individual warranties covered:
- Solar Workmanship Warranty: Many defunct installations claim a "10-year warranty", which was only a workmanship warranty. If individual parts fail and the installer shuts down, the warranty disappears. Insist on backed warranties from established companies.
- Solar Performance & Product Warranty: Choose Tier-1 solar panel manufacturers offering a 25-year performance warranty and a minimum 10 to 15-year product warranty.
- Solar Inverter Warranty: The inverter is the hardest-working brain of your system. Always select reputable inverters (Fronius, Sungrow, Enphase, SolarEdge) that have a physical support presence in Australia.
Do I Need to Choose a NETCC Approved Solar Seller?
In one word — Yes!
The solar panel installer you choose must be an approved signatory of the New Energy Tech Consumer Code (NETCC Approved Seller). This ensures adherence to strict safety standards, consumer protections, clear contracts, and eligibility for Victorian Government Solar Rebates (Solar Victoria).
Always check customer reviews, request real customer references, and check if the installer has successfully delivered substantial commercial installations in Victoria like we do at Billabong Solar.
