How Waterlooville compares
Among the places we publish figures for, Waterlooville is one of 45 Hampshire towns we track, and it ranks joint 9th of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 34,703 residents, and its roofs see 3.08 peak sun hours a day across the year. That drives the standard 12 panel model to 7,155 kWh of generation, of which around 6,218 kWh is exported at 12p for £746 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Waterlooville'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.
Planning applications here go through Havant; nationally, the House of Commons Library classes Waterlooville 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.

SSEN and your Waterlooville connection
Waterlooville sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Waterlooville
A heat pump in Waterlooville
Heating demand peaks when solar is weakest. In Waterlooville, a 12-panel system makes about 250 kWh in December and 270 kWh in January, a fraction of its 890 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Waterlooville
Summer is where a car earns its place. In July, 12 panels in Waterlooville make about 890 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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).

Common questions about solar in Waterlooville
How much electricity do solar panels make in Waterlooville?
About 7,160 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Waterlooville: 1,125 kWh per kWp, or 3.08 peak sun hours a day on average. July is the strongest month, at about 890 kWh.
What does a typical solar system cost in Waterlooville?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Waterlooville, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,160 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Waterlooville, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Waterlooville. 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 happens to the solar I do not use in Waterlooville?
Around £746 a year at 12p per kWh, for the roughly 6,218 kWh a 12-panel system in Waterlooville exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Waterlooville get in December?
December is the low point: about 250 kWh from a 12-panel system in Waterlooville, on PVGIS data, rising to 890 kWh in July. From November to February the same system makes about 1,210 kWh in total, which is why a battery charged off-peak does more of the work in winter.
