Solar FAQs

Panels convert sunlight into electricity you can use straight away in your home, with any surplus either stored in a battery (if you have one) or exported back to the grid.

Most roofs can support solar, though orientation, shading, and roof condition all affect how well it performs. An installer will assess your specific roof as part of the process.

This can depend on your system size and local council rules. Your installer will confirm what applies to your situation.

EECA indicates a typical payback period of around 7–10 years, where a household uses most of its solar generation, has average-to-high daytime electricity use, and has electric heating and hot water. It can take longer for other households. Faster payback is more likely in sunnier parts of the country or where power prices are higher. Source: EECA

Yes, using solar electricity in your home reduces how much you need to buy from the grid. Using appliances, hot water heating, or EV charging during daylight hours generally improves the value you get from it. Source: EECA

Surplus electricity can often earn export credits through your retailer's buyback plan. Rates and conditions vary by retailer, so it's worth checking what your provider offers. Source: EECA

A battery is optional. It stores electricity for later use, but adds to the upfront cost and usually lengthens payback. Ordinary grid-connected solar panels don't provide backup power during an outage on their own; that needs a suitably configured system with a backup-capable inverter, a battery, and dedicated circuits for essential appliances.

Yes, though less than on a clear sunny day. Panels still generate power, just at a reduced rate. Output varies with weather, season, and shading.

EECA indicates well-maintained panels typically last 25–30 years, with only a small decrease in output over time. Inverters usually need replacing after about 10–15 years, depending on quality. Lifespan and warranty period aren't the same thing, so it's worth checking both when comparing quotes. Source: EECA

Physical installation commonly takes 1–2 days. The full process (approvals, meter reconfiguration, and inspection) typically wraps up within about 4 weeks, though your installer will confirm the timeline for your specific job. Source: EECA

Yes, the form includes an option for exactly that. There's no pressure to move forward.

No. We review each enquiry, and only suitable ones are referred to installers. Submitting doesn't guarantee installer contact or a formal quote.

Up to three suitable installers, though some enquiries are referred to one installer exclusively.

They're not strictly required, but they're strongly recommended. They help installers understand your property before the first call, so it's more useful and less repetitive.

Yes, the form lets you mention interest in battery storage alongside solar. Residential solar is our primary focus.
