How Clay Cross compares
Small towns rarely get published solar figures, so here are the numbers for Clay Cross. It is one of 28 Derbyshire towns we track, and it ranks 17th of 28 for solar yield, a town of 9,773 people in the House of Commons Library settlement data. PVGIS gives its roofs 959 kWh per kWp a year, 2.63 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £867 of year one benefit, £247 of it from your own generation and £620 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Clay Cross' own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
North East Derbyshire is the planning authority covering Clay Cross, which the House of Commons Library classes as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Generation is modelled from PVGIS satellite data for Clay Cross' own coordinates (53.16631, -1.40958), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Who runs the grid in Clay Cross
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Clay Cross, as part of its East Midlands licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Clay Cross
A heat pump in Clay Cross
A heat pump does most of its work from November to February. Over those four months, 12 panels in Clay Cross make about 990 kWh, against 2,940 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Clay Cross
From April to September, 69% of a Clay Cross roof's yearly output arrives, peaking at about 770 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Clay Cross
What does a solar panel system produce in Clay Cross?
Each kWp of panels in Clay Cross makes 959 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,100 kWh, from about 190 kWh in December up to 770 kWh in May.
How much are solar panels in Clay Cross?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Clay Cross before a battery. What Clay Cross changes is the return, about 6,100 kWh a year from that system, and your design call prices your actual roof.
Would a system in Clay Cross need approval from the network operator?
Clay Cross is on National Grid Electricity Distribution's network (East Midlands licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Clay Cross?
With typical use and no battery, a 12-panel system in Clay Cross exports about 5,163 kWh a year. At 12p per kWh that is roughly £620; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Clay Cross in winter?
It works, but the year is lopsided. 69% of a Clay Cross roof's output lands between April and September; the four months from November to February give about 990 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Clay Cross compares with its neighbours
How the towns nearest Clay Cross compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Clay Cross |
|---|---|---|
| Clay Cross | 959 | this town |
| North Wingfield and Holmewood | 954 | −5 kWh |
| Alfreton | 965 | +6 kWh |
| South Normanton | 955 | −4 kWh |
| Chesterfield | 957 | −2 kWh |
| Brimington | 954 | −5 kWh |
| Matlock | 943 | −16 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
