FAQ
Installation & Suitability
UK solar panels generate electricity from daylight, not just direct sunshine. The South West has some of the highest solar irradiance levels in the UK, making it one of the best regions for solar generation.
South-facing roofs are ideal, but east, west, and even north-facing roofs can still generate meaningful amounts of electricity depending on pitch and shading. We model every roof individually before recommending a system.
Most residential systems are installed in a single day. Larger commercial systems may take 2–3 days.
most solar installations fall under permitted development rights and do not require planning permission. Exceptions include listed buildings and some conservation areas. We confirm this during your survey.
Costs & Savings
typical residential system (4–6 kWp) costs between £5,000 and £9,000 fully installed. Prices vary based on system size, panel brand, and whether battery storage is included. We offer finance options to spread this cost.
Savings depend on your energy usage, system size, and energy tariff. Typical residential savings range from £500 to £1,200 per year. Use our calculator for a tailored estimate.
SEG is a government-backed scheme that requires energy suppliers to pay you for electricity you export back to the grid. All MCS-certified installations automatically qualify. Rates vary by supplier.
Typically 6–10 years for residential systems. After payback, the electricity your system generates is effectively free.
Finance & Grants
Depending on your circumstances, you may be eligible for ECO4 funding or other Warm Homes grant schemes. Our partner EcoGrants can check your eligibility for free.
We offer 0% interest finance, monthly solar plans, and deferred payment options.
Battery Storage
In most cases, yes. We assess your current system and inverter during a free survey and recommend a compatible battery solution.
Home battery systems provide backup power during grid outages. This depends on the battery type and configuration. Ask our team about blackout-rated batteries during your survey.
