How Saltash compares
Small towns rarely get published solar figures, so here are the numbers for Saltash. It is one of 14 Cornwall towns we track, and it ranks 4th of 14 for solar yield, a town of 15,209 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,065 kWh per kWp a year, 2.92 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £947 of year one benefit, £247 of it from your own generation and £700 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Saltash'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.
Cornwall is the planning authority covering Saltash, 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.

Who runs the grid in Saltash
On NESO's licence-area map, Saltash is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
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 Saltash
A heat pump in Saltash
A heat pump does most of its work from November to February. Over those four months, 12 panels in Saltash make about 1,160 kWh, against 3,200 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Saltash
A 12-panel roof in Saltash makes about 830 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 Saltash
What does a solar panel system produce in Saltash?
Each kWp of panels in Saltash makes 1,065 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,770 kWh, from about 230 kWh in December up to 830 kWh in May.
How much are solar panels in Saltash?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Saltash before a battery. What Saltash changes is the return, about 6,770 kWh a year from that system, and your design call prices your actual roof.
Would a system in Saltash need approval from the network operator?
Saltash is on National Grid Electricity Distribution's network (South West England 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 Saltash?
With typical use and no battery, a 12-panel system in Saltash exports about 5,837 kWh a year. At 12p per kWh that is roughly £700; 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 Saltash in winter?
It works, but the year is lopsided. 68% of a Saltash roof's output lands between April and September; the four months from November to February give about 1,160 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Saltash compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Saltash.

| Tavistock | 987 | −78 kWh |
| Liskeard | 1,042 | −23 kWh |

| Launceston | 995 | −70 kWh |
| Bodmin | 1,039 | −26 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.
