Solar Panel & Battery Installers in Derby

If you are looking for solar panel installers in Derby, we can match you with one for free. You fill in a short form about your home and your energy use. We then pass your details to an MCS-certified installer who can quote.

Our approach is battery-led, since a battery lets you keep more of what the panels make. However, we do not carry out installations ourselves. The installer you are matched with surveys the roof and fits the system.

Detached roofs are often larger. For example, a big roof may take more panels than the home uses by day. In that case, the battery should match your evening use.

PVGIS, the EU's free modelling tool, puts a 4 kWp array in Derby at about 3,900 kWh a year. The model assumes a south-facing roof at 35 degrees and 14% losses. As a result it is a fair benchmark, although your own roof will differ.

Derby sits a little below the south-coast figures, so a well-sized battery matters more here. For instance, our solar battery size calculator guide shows how to match storage to your evening use. It works through the sums step by step.

Panels still work in cloudy weather, but they make less. Therefore yearly figures help more than a single sunny day. Ask any firm to show its yearly estimate and the method behind it.

Census 2021 shows that Derby has a high share of detached homes, at 24.1%. Semi-detached homes make up 39.1%, while terraces make up 21.8% and flats 14.7%. Therefore most households have a roof of their own to use.

That said, a roof of your own does not guarantee a good one. Ask your installer to check direction, pitch, shade and the state of the tiles. Older roofs may need repairs first, because panels stay up for many years.

Derby City Council has designated sixteen conservation areas, including Darley Abbey, Friar Gate, the Arboretum, Allestree, Mickleover and Spondon. In England, a roof slope in these areas is generally fine for panels. Walls that face the street are restricted, however, and listed buildings need consent.

Because rules changed on 27 August 2026, confirm the details before you sign. The council's planning pages are the place to check a specific street.

Your installer tells the local network operator about your system, and some sizes need approval first. The names for these routes are G98 and G99. National Grid Electricity Distribution is understood to cover Derby, although your installer checks this from your postcode.

Electrical work in a home must also meet building rules. A registered installer normally does the paperwork and gives you the certificates. Therefore ask to see them before you pay the final bill.

The government's Warm Homes: Local Grant list shows Derby within the Midlands Net Zero Hub award. The grant is meant for low-income households in homes rated EPC D to G. Although it can include solar panels, it will not suit most homeowners.

There is no successor to ECO4, which ends on 31 December 2026, and the Great British Insulation Scheme has closed. In contrast, the VAT cut still applies. Solar panels and batteries are VAT-free (0%) until 31 March 2027, then 5%.

MCS certification matters because it unlocks Smart Export Guarantee payments. MIS 3002 sets the standard for panels and MIS 3012 for batteries. For instance, you can check a firm on the MCS website before you accept a quote.

Under the SEG, suppliers pay for surplus power, and each sets its own rate. At the time of writing (October 2026), Octopus's open tariff paid 4.1p per kWh, while British Gas paid 3p to customers of other suppliers. Our guide to the Smart Export Guarantee with a battery shows how to compare them.

Good quotes list the panels, inverter, battery size, monitoring and warranties. Read about solar panel installation and solar and battery bundles before you compare. Additionally, smart energy monitoring shows what the system makes once it runs.

Ask each firm how long the work will take. Since warranties differ, get the terms in writing. Moreover, ask for a plain summary of what the battery will and will not do.

Panels are only part of the bill. The inverter, mounting and labour all count, as does the battery. Therefore compare the same items across each quote.

Inverters shape how a system behaves, so our upcoming guide to solar inverters explains hybrid and string types. It uses plain words and worked examples, because the topic is full of jargon.
