5 Questions to ask an installer before signing up for solar

1. What exact system components are you installing?

Ask the company what they provide in a Solar system. What type of technology is used in solar panels, the brand of solar inverter, and the solar battery( if included)?

Why: Some installers quote a premium but install a cheap quality solar system at the customer's site. Make sure you are getting brands like Jinko, LUNGI, and SUNPOWER if they promise a premium quality product in their solar quotes.

2. What is the total system performance estimate?

Ask the solar expert about daily unit generation ( KWH/day), annual output estimate, based on your roof direction and shading. It helps you to understand solar energy generation and how you can reduce your electricity bill with solar energy.

For example, a 6.6 KW an average solar system in Perth, which roughly produces 24-28 units/day depending on conditions.

3. What warranties do I get (and who handles them)?

Always check:

Solar panels' performance warranty( usually 25 years)
Product warranty(10-25 years)
Solar inverter warranty(5-10 years)
Workmanship warranty(installer)

Why: some companies disappear later - ask who you will call if something fails or you face a solar query.

4. Is the installer CEC accredited, and do you use in-house installers?

Ask them:

Are your installers Clean Energy Council (CEC) accredited?
Do you use subcontractors or your own team?

Why: proper accreditation = safer, compliant installation( important for rebates). If your installers are not CEC proven, then you can not claim a government rebate.

5. What is included in the final price (any hidden costs)?

Clarify to solar installers:

Installation cost
Meter upgrade/ grid connection fees
Monitoring system
Extra charges ( tile roof, double story, switchboard upgrade)

Why: cheap quotes often exclude key costs and increase later.

Bonus tip: also ask the solar installer to show me recent installs or customer reviews in Perth?
