How Melksham compares
Small towns rarely get published solar figures, so here are the numbers for Melksham. It is one of 20 Wiltshire towns we track, and it ranks joint 5th of 20 for solar yield, a town of 18,552 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,031 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £921 of year one benefit, £247 of it from your own generation and £674 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Melksham'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.
Wiltshire is the planning authority covering Melksham, 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 Melksham's own coordinates (51.37474, -2.13264), 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 Melksham
The distribution network operator (DNO) for Melksham is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England 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 Melksham
A heat pump in Melksham
A heat pump does most of its work from November to February. Over those four months, 12 panels in Melksham make about 1,110 kWh, against 3,100 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Melksham
A 12-panel roof in Melksham makes about 800 kWh in July. 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.

Melksham solar questions
What does a solar panel system produce in Melksham?
Each kWp of panels in Melksham makes 1,031 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,560 kWh, from about 230 kWh in December up to 800 kWh in July.
How much are solar panels in Melksham?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Melksham before a battery. What Melksham changes is the return, about 6,560 kWh a year from that system, and your design call prices your actual roof.
Would a system in Melksham need approval from the network operator?
Melksham is on Scottish and Southern Electricity Networks' network (Southern England 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 Melksham?
With typical use and no battery, a 12-panel system in Melksham exports about 5,620 kWh a year. At 12p per kWh that is roughly £674; 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 Melksham in winter?
It works, but the year is lopsided. 68% of a Melksham roof's output lands between April and September; the four months from November to February give about 1,110 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
