How long does solar panel installation take in Southwold?

A standard residential solar panel installation in Southwold 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.

Most Southwold customers are generating electricity within 2–4 weeks of enquiry.

What is the Smart Export Guarantee and can I earn money from solar in Southwold?

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 Southwold 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.

What solar panel brands do you install in Southwold?

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 Southwold roof's orientation, shading profile, and energy usage during the free survey.

Is my Southwold home suitable for solar panels?

The vast majority of Southwold 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 Southwold area's Coastal exposure provides excellent solar conditions. Adnams Brewery solar installation demonstrates commercial solar viability in the area. makes it an excellent location for solar.

How Solar Panel Installation Works in Southwold

Free survey and roof assessment

We visit your Southwold property to assess roof orientation, pitch, condition, available area, shading, and electrical connection point. We design your system and provide a detailed, fixed-price quote at no charge.

System design and paperwork

We handle all grid connection notifications (G99/G98), any required planning consent, and DNO applications on your behalf. Most systems are notified — not approved — meaning installation can proceed immediately.

Installation — typically 1–2 days

Our MCS-certified engineers mount the racking, install panels, run cable to the inverter location, and connect the system. We commission and test generation, export metering, and the monitoring app before leaving.

Smart Export Guarantee and monitoring setup

We register your system with your energy supplier for SEG payments and set up the monitoring app (Fox ESS, SolarEdge, or Huawei FusionSolar) so you can track generation and savings in real time.
