Most residential solar panel installations in Leiston are permitted development and do not require planning permission.

We advise on planning requirements during the free survey at no charge.

A standard residential solar panel installation in Leiston typically takes 1–2 days. A 4 kW system (10 panels) is usually completed in a single day; larger 6–10 kW systems take 1.5–2 days.

The Smart Export Guarantee (SEG) requires energy suppliers to pay you for electricity you export to the grid. Rates typically range from 4–15p/kWh depending on the tariff — with some Octopus Energy tariffs offering up to 24p/kWh at peak times. For a 4 kW system in Leiston exporting approximately 1,500–2,000 kWh per year, SEG income adds £60–£300 per year on top of your self-consumption savings. Adding battery storage reduces exports but increases self-use savings, which are more valuable at current electricity prices.

We install premium solar panels from REC, Trina Solar, JA Solar, and Jinko Solar — all Tier 1 manufacturers with 25-year performance warranties. For inverters, we use SolarEdge (with panel-level optimisation, ideal for roofs with partial shading), Fox ESS (for solar-plus-battery installations), and Huawei FusionHome. We recommend the right combination for your Leiston roof's orientation, shading profile, and energy usage during the free survey.

The vast majority of Leiston homes are suitable for solar panels. South, southwest, and southeast facing roofs give the best output; east or west facing roofs still generate 80–90% of optimum yield. Roofs with a pitch of 20–50° are ideal. We can install on flat roofs using angled mounting frames. Shading from chimneys or trees is assessed at the survey — panel-level optimisers (SolarEdge) resolve most shading issues. The Leiston area's Coastal Suffolk location with excellent solar generation potential. The flat terrain and proximity to the coast provide minimal shading and clear skies. makes it an excellent location for solar.
