How Barnham compares
Small towns rarely get published solar figures, so here are the numbers for Barnham. It is one of 33 Sussex towns we track, and it ranks 11th of 33 for solar yield, a town of 11,733 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,148 kWh per kWp a year, 3.15 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,011 of year one benefit, £247 of it from your own generation and £764 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Barnham's own yield.
Planning applications here go through Arun; nationally, the House of Commons Library classes Barnham 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 Barnham's own coordinates (50.83836, -0.64756), 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.
The network operator for Barnham
Barnham 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.

Beyond the panels: heating and car charging in Barnham
A heat pump in Barnham
Heating demand peaks when solar is weakest. In Barnham, a 12-panel system makes about 250 kWh in December and 270 kWh in January, a fraction of its 920 kWh in July, 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 Barnham
Summer is where a car earns its place. In July, 12 panels in Barnham make about 920 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.
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.

Common questions about solar in Barnham
How much energy would 12 solar panels make in Barnham?
Barnham averages 3.15 peak sun hours a day, which PVGIS turns into 1,148 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 7,300 kWh, 69% of it between April and September.
What does a typical solar system cost in Barnham?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Barnham, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,300 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Barnham, and do I need a G99 application?
The operator is Scottish and Southern Electricity Networks (SSEN). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Barnham?
Around £764 a year at 12p per kWh, for the roughly 6,365 kWh a 12-panel system in Barnham exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Barnham in the winter months?
December is the weakest month in Barnham: about 250 kWh from 12 panels, against 920 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
