How Caversham compares
Among the places we publish figures for, Caversham is one of 10 Oxfordshire towns we track, and it ranks joint 2nd of 10 for solar yield. It is a medium town in the House of Commons Library classification, with 32,846 residents, and its roofs see 2.81 peak sun hours a day across the year. That drives the standard 12 panel model to 6,519 kWh of generation, of which around 5,582 kWh is exported at 12p for £670 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Caversham's own yield.
Caversham sits within Reading, its local planning authority, and the House of Commons Library classes it as a medium 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.

Connecting solar to the Caversham network
Caversham is served by Scottish and Southern Electricity Networks (SSEN): the town's centre falls inside its Southern England licence area on NESO's boundary map.
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: SSEN 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. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Beyond the panels: heating and car charging in Caversham
A heat pump in Caversham
Solar and a heat pump pull in opposite directions through the year: Caversham's roofs make 1,130 kWh from November to February on a 12-panel system, and 3,070 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Caversham
From April to September, 68% of a Caversham roof's yearly output arrives, peaking at about 800 kWh in July 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 Caversham
What could a roof in Caversham generate?
PVGIS puts a roof in Caversham at 1,025 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,520 kWh a year, most of it between April and September.
How much are solar panels in Caversham?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Caversham before a battery. What Caversham changes is the return, about 6,520 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Caversham?
Usually not in advance. SSEN, the network operator for Caversham, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. "See our DNO explainer.
How much can I earn from exporting solar in Caversham?
With typical use and no battery, a 12-panel system in Caversham exports about 5,582 kWh a year. At 12p per kWh that is roughly £670; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Caversham?
Yes, at a lower level. PVGIS gives Caversham 36.5 kWh per kWp in December and 41.1 in January, so a 12-panel system makes about 230 kWh and 260 kWh in those months, against 800 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Caversham compares with its neighbours
How the towns nearest Caversham compare on the same PVGIS settings, closest first.

| Woodley | 1,021 | −4 kWh |

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
