How Aberystwyth compares
Small towns rarely get published solar figures, so here are the numbers for Aberystwyth. It is the only Cardiganshire town we track so far, with county rankings to follow as its neighbours land, a town of 15,677 people in the House of Commons Library settlement data. PVGIS gives its roofs 947 kWh per kWp a year, 2.60 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £857 of year one benefit, £247 of it from your own generation and £610 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Aberystwyth's 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.
Aberystwyth sits within Ceredigion, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Aberystwyth network
Aberystwyth is served by SP Energy Networks: the town's centre falls inside its North Wales, Merseyside and Cheshire licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SP Energy Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
A bigger inverter or battery output needs a G99 application in advance. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Adding a heat pump or an EV charger in Aberystwyth
A heat pump in Aberystwyth
Solar and a heat pump pull in opposite directions through the year: Aberystwyth's roofs make 940 kWh from November to February on a 12-panel system, and 2,910 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Aberystwyth
A 12-panel roof in Aberystwyth makes about 790 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Aberystwyth
What could a roof in Aberystwyth generate?
PVGIS puts a roof in Aberystwyth at 947 kWh per kWp a year, 2.60 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,020 kWh a year, most of it between April and September.
How much are solar panels in Aberystwyth?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Aberystwyth before a battery. What Aberystwyth changes is the return, about 6,020 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Aberystwyth?
Usually not in advance. SP Energy Networks, the network operator for Aberystwyth, 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator. "See our DNO explainer.
How much can I earn from exporting solar in Aberystwyth?
With typical use and no battery, a 12-panel system in Aberystwyth exports about 5,086 kWh a year. At 12p per kWh that is roughly £610; 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 Aberystwyth?
Yes, at a lower level. PVGIS gives Aberystwyth 26.9 kWh per kWp in December and 31.5 in January, so a 12-panel system makes about 170 kWh and 200 kWh in those months, against 790 kWh in May. Winter output mostly covers daytime use rather than exporting.

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.
