How Totton compares
Among the places we publish figures for, Totton is one of 45 Hampshire towns we track, and it ranks 30th of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 28,448 residents, and its roofs see 2.94 peak sun hours a day across the year. That drives the standard 12 panel model to 6,824 kWh of generation, of which around 5,888 kWh is exported at 12p for £707 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 Totton'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.
Totton sits within New Forest, its local planning authority, and the House of Commons Library classes it as a 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.

Generation is modelled from PVGIS satellite data for Totton's own coordinates (50.92041, -1.50353), 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.
Connecting solar to the Totton network
The distribution network operator (DNO) for Totton is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SSEN is notified within 28 days of switch-on rather than asked beforehand.
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.

Heat pumps and EV charging in Totton
A heat pump in Totton
Solar and a heat pump pull in opposite directions through the year: Totton's roofs make 1,180 kWh from November to February on a 12-panel system, and 3,220 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Totton
A 12-panel roof in Totton makes about 840 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Totton solar questions
What could a roof in Totton generate?
PVGIS puts a roof in Totton at 1,073 kWh per kWp a year, 2.94 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,820 kWh a year, most of it between April and September.
What would 12 solar panels cost in Totton?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Totton differs is output: about 6,820 kWh a year from that system.
Do I need permission from the DNO for solar in Totton?
Usually not in advance. SSEN, the network operator for Totton, 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. 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. "See our DNO explainer.
How much would export pay on a system in Totton?
It is exported. With typical use and no battery, about 5,888 kWh of the 6,820 kWh a 12-panel system makes in Totton goes to the grid, around £707 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Totton?
Yes, at a lower level. PVGIS gives Totton 37.7 kWh per kWp in December and 42.3 in January, so a 12-panel system makes about 240 kWh and 270 kWh in those months, against 840 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Totton compares with its neighbours
How the towns nearest Totton compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Totton |
|---|---|---|
| Totton | 1,073 | this town |
| Southampton | 1,080 | +7 kWh |
| Romsey | 1,063 | −10 kWh |
| Hythe and Dibden Purlieu | 1,107 | +34 kWh |
| Chandler's Ford | 1,064 | −9 kWh |
| West End | 1,085 | +12 kWh |
| Eastleigh | 1,070 | −3 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
