How Chichester compares
Among the places we publish figures for, Chichester is one of 33 Sussex towns we track, and it ranks 2nd of 33 for solar yield. It is a medium town in the House of Commons Library classification, with 34,608 residents, and its roofs see 3.22 peak sun hours a day across the year. That drives the standard 12 panel model to 7,473 kWh of generation, of which around 6,536 kWh is exported at 12p for £784 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
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 Chichester's own yield.
Planning applications in Chichester go to its own council, 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 Chichester's own coordinates (50.84029, -0.77642), 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 Chichester network
Chichester is served by Scottish and Southern Electricity Networks (SSEN): the town's centre falls inside its Southern England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SSEN within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Beyond the panels: heating and car charging in Chichester
A heat pump in Chichester
Solar and a heat pump pull in opposite directions through the year: Chichester's roofs make 1,240 kWh from November to February on a 12-panel system, and 3,570 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Chichester
A 12-panel roof in Chichester makes about 930 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.
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 Chichester: your questions answered
What could a roof in Chichester generate?
PVGIS puts a roof in Chichester at 1,175 kWh per kWp a year, 3.22 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,470 kWh a year, most of it between April and September.
How much are solar panels in Chichester?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Chichester before a battery. What Chichester changes is the return, about 7,470 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Chichester?
Usually not in advance. SSEN, the network operator for Chichester, 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 can I earn from exporting solar in Chichester?
With typical use and no battery, a 12-panel system in Chichester exports about 6,536 kWh a year. At 12p per kWh that is roughly £784; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Chichester?
Yes, at a lower level. PVGIS gives Chichester 40.7 kWh per kWp in December and 43 in January, so a 12-panel system makes about 260 kWh and 270 kWh in those months, against 930 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Chichester compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Chichester.
| Town | kWh per kWp a year | vs Chichester |
|---|---|---|
| Chichester | 1,175 | this town |
| Bognor Regis | 1,141 | −34 kWh |
| Barnham | 1,148 | −27 kWh |
| Emsworth | 1,146 | −29 kWh |
| Selsey | 1,155 | −20 kWh |
| Havant | 1,133 | −42 kWh |
| South Hayling | 1,127 | −48 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.

Guides worth reading before your call
Sourced, dated and written by us. The same ground we cover on your free call.
How to clean solar panels, and whether you need to at all
Cleaning is oversold and pigeon mesh is undersold. The numbers behind both.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Three phase and EV charging: what actually changes
Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
Read the guide →How an air source heat pump actually works
It moves heat rather than making it. The cycle, the efficiency numbers and the trade-offs.
Read the guide →Which tariffs are actually built for battery charging
A battery buys cheap and uses dear. The tariff decides how much that is worth.
Read the guide →G98 or G99: which one applies, what the application involves, and how long it takes
The G98 line sits at 3.68kW per phase. Above it, your network operator has to say yes first.
