FAQs
Questions Melbourne homeowners ask us
How do I get started with a solar installation?
Call us or request a free quote online. We'll ask about your bills, roof and switchboard, then design a system and give you a fixed written quote — no obligation, no door-knockers.
Do solar panels work on cloudy days?
Yes — output drops but doesn't stop. A well-sized system is designed around your annual usage, and pairing it with a battery lets you ride through low-generation days.
Am I eligible for Victorian solar rebates?
Most owner-occupied homes under the income and property-value thresholds qualify for Solar Victoria rebates. As a Solar Victoria Authorised Retailer we handle the paperwork and confirm your eligibility before you commit.
Can you install a battery if my solar was installed by someone else?
Absolutely — battery retrofits are one of our core services. We assess your existing inverter and switchboard, then recommend a compatible battery with backup supply.
What warranty do I get?
A 5-year installation workmanship warranty from us, on top of the manufacturer warranties on panels (typically 25 years performance), inverters and batteries (typically 10 years).
