Do I need planning permission for solar panels in Dereham?

Most of Dereham has standard permitted development for solar. The historic town centre has a small conservation area. Agricultural and commercial buildings in the area typically have straightforward planning. We advise on planning requirements during the free survey at no charge.

How long does solar panel installation take in Dereham?

A standard residential solar panel installation in Dereham 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. We conduct a free pre-installation survey to assess roof structure, confirm system design, and arrange any scaffolding. Most Dereham customers are generating electricity within 2–4 weeks of enquiry.

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

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 Dereham 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 Dereham?

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

Is my Dereham home suitable for solar panels?

The vast majority of Dereham 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 Dereham area's Dereham and mid-Norfolk receive good solar irradiance with relatively flat terrain. The town's industrial estates and surrounding agricultural buildings offer significant commercial solar opportunities alongside steady residential demand. makes it an excellent location for solar.

How Solar Panel Installation Works in Dereham

Free survey and roof assessment

We visit your Dereham 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.
