Against Great Britain as a whole: Westhill makes 810 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Westhill is 12% below it.
How Westhill compares
Small towns rarely get published solar figures, so here are the numbers for Westhill. It is one of 4 Inverness-shire towns we track, and it ranks 1st of 4 for solar yield, a town of 11,359 people in the House of Commons Library settlement data. PVGIS gives its roofs 810 kWh per kWp a year, 2.22 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £753 of year one benefit, £247 of it from your own generation and £506 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Westhill'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.
Highland is the planning authority covering Westhill, 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 Westhill
The distribution network operator (DNO) for Westhill is Scottish and Southern Electricity Networks (SSEN), which runs the North Scotland licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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.

Adding a heat pump or an EV charger in Westhill
A heat pump in Westhill
A heat pump does most of its work from November to February. Over those four months, 12 panels in Westhill make about 620 kWh, against 2,660 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
Scottish homes apply through Home Energy Scotland rather than the Boiler Upgrade Scheme: up to £7,500 in grant for a heat pump, up to £7,500 more as an optional interest-free loan, and a £1,500 uplift for rural and island homes (checked 28 September 2026).
Charging an EV in Westhill
A 12-panel roof in Westhill makes about 730 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Westhill solar questions
What does a solar panel system produce in Westhill?
Each kWp of panels in Westhill makes 810 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,150 kWh, from about 90 kWh in December up to 730 kWh in May.
How much are solar panels in Westhill?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Westhill before a battery. What Westhill changes is the return, about 5,150 kWh a year from that system, and your design call prices your actual roof.
Would a system in Westhill need approval from the network operator?
Westhill is on Scottish and Southern Electricity Networks' network (North Scotland licence area). Systems up to 3.68kW per phase of inverter output follow G98: SSEN is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Westhill?
With typical use and no battery, a 12-panel system in Westhill exports about 4,215 kWh a year. At 12p per kWh that is roughly £506; 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 Westhill in winter?
It works, but the year is lopsided. 73% of a Westhill roof's output lands between April and September; the four months from November to February give about 620 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Westhill compares with its neighbours
How the towns nearest Westhill compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Westhill |

| Balloch | 809 | −1 kWh |
| Inbhir Nis | 807 | −3 kWh |
| Nairn | 845 | +35 kWh |
| Forres | 840 | +30 kWh |
| Elgin | 873 | +63 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.

Retrofitting a battery to working solar is straightforward. The paperwork is where people trip up.

Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
