Independent, experience-led guidance from Victoria’s solar installer community, created to help homeowners cut through sales noise, understand what really matters, and make a confident, informed decision before investing in solar. This guide reflects what experienced installers see every day: what works, what fails, and where poor decisions can cost you long after the system is switched on.
A practical guide from Victoria’s installer community.
Buying solar is a big decision — and choosing the right installer matters just as much as choosing the right equipment.
SEIA VIC represents Victoria’s solar installer community and believes solar should be trusted, respected, and done properly. This practical guide is designed to help you understand what to look for beyond quotes and promises, so you can assess experience, quality, and long-term reliability with confidence.
You’re about to invest a significant amount of money in your home. Take your time, ask the right questions, and choose an installer who will stand behind their work — not just on install day, but for years to come.
How long have they been around?
A business with history gives you confidence that they’ll still be there when you need support.
Are they close enough to provide after-sales service?
Solar isn’t “set and forget.” If something goes wrong, distance matters. A nearby installer can help quickly.
Are they employees of the company?
Commission-only sales reps may focus on the sale rather than the solution. High-pressure tactics and exaggerated promises are common warning signs.
Do they have design or installation experience?
If the person quoting hasn’t been involved in actual installations, they may not understand your site, shading, switchboard, or real-world system behaviour.
Good installers explain the “why,” not just the “what.”
Who will physically install the system?
Employees or long-term contractors on hourly rates usually take the time to do the job properly.
Cheap fixed-price contractors may rush — which often leads to poor workmanship.
Is an accredited installer on site?
For STCs (your rebate) to be valid, an accredited installer must be present.
Ask for their accreditation number — and check that they actually turn up.
Does each manufacturer have an Australian office or a long-standing authorised distributor?
If yes → you’re likely to receive proper warranty support.
If the warranty is held only by the retailer → support may disappear if the company does.
Solar history is full of “here today, gone tomorrow” retailers. Choose brands with staying power.
Who will support you after the installation?
If the company is far away, unavailable, or difficult to contact, resolving issues can take weeks or months.
A reputable installer:
After-sales service is the true test of a solar company.
A good quote is based on a good design.

A proper design shows your installer has done the thinking, not just the maths.

These should raise caution immediately:
If something doesn’t feel right, stop and check.
A quality installation is a safe installation.
Your installer should:
A safe system protects your home and your investment.
There are no shortcuts in good solar.
