How Andover compares
Among the places we publish figures for, Andover is one of 45 Hampshire towns we track, and it ranks joint 36th of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 50,888 residents, and its roofs see 2.84 peak sun hours a day across the year. That drives the standard 12 panel model to 6,595 kWh of generation, of which around 5,659 kWh is exported at 12p for £679 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Andover's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Any planning application in Andover sits with Test Valley, and its official House of Commons Library settlement class is 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.

SSEN and your Andover connection
The distribution network operator (DNO) for Andover 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.
Above that, G99 means applying before the work is booked. 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.

Heat pumps and EV charging in Andover
A heat pump in Andover
Heating demand peaks when solar is weakest. In Andover, a 12-panel system makes about 230 kWh in December and 260 kWh in January, a fraction of its 790 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Andover
Andover's May output, about 790 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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.

Solar in Andover: your questions answered
How much electricity do solar panels make in Andover?
About 6,600 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Andover: 1,037 kWh per kWp, or 2.84 peak sun hours a day on average. May is the strongest month, at about 790 kWh.
Is solar more expensive in Andover?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Andover, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,600 kWh a year here, which is what drives payback.
Which DNO covers Andover, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Andover. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Andover?
On the 12p export scenario, a 12-panel system in Andover sends about 5,659 kWh a year to the grid, worth around £679. The export rates table compares what each supplier pays.
How much solar does Andover get in December?
December is the low point: about 230 kWh from a 12-panel system in Andover, on PVGIS data, rising to 790 kWh in May. From November to February the same system makes about 1,130 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Andover compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Andover.
| Town | kWh per kWp a year | vs Andover |
|---|---|---|
| Andover | 1,037 | this town |
| Tidworth | 1,044 | +7 kWh |
| Durrington and Bulford | 1,045 | +8 kWh |
| Amesbury | 1,044 | +7 kWh |
| Winchester | 1,037 | level |
| Newbury | 1,034 | −3 kWh |
| Romsey | 1,063 | +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.

More panel capacity than inverter capacity is a deliberate design choice.
