How Canvey Island compares
Among the places we publish figures for, Canvey Island is one of 46 Essex towns we track, and it ranks joint 11th of 46 for solar yield. It is a medium town in the House of Commons Library classification, with 38,242 residents, and its roofs see 2.96 peak sun hours a day across the year. That drives the standard 12 panel model to 6,862 kWh of generation, of which around 5,926 kWh is exported at 12p for £711 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 Canvey Island's own yield.
Castle Point is the planning authority covering Canvey Island, which the House of Commons Library classes 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 Canvey Island's own coordinates (51.52008, 0.57747), 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.
Who runs the grid in Canvey Island
Canvey Island sits in UK Power Networks' East England licence area, so UK Power Networks is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
Anything bigger is a G99 case and is applied for first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Beyond the panels: heating and car charging in Canvey Island
A heat pump in Canvey Island
A heat pump does most of its work from November to February. Over those four months, 12 panels in Canvey Island make about 1,170 kWh, against 3,240 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Canvey Island
A 12-panel roof in Canvey Island 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).

Common questions about solar in Canvey Island
What does a solar panel system produce in Canvey Island?
Each kWp of panels in Canvey Island makes 1,079 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,860 kWh, from about 240 kWh in December up to 840 kWh in July.
How much are solar panels in Canvey Island?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Canvey Island before a battery. What Canvey Island changes is the return, about 6,860 kWh a year from that system, and your design call prices your actual roof.
Would a system in Canvey Island need approval from the network operator?
Canvey Island is on UK Power Networks' network (East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Canvey Island?
With typical use and no battery, a 12-panel system in Canvey Island exports about 5,926 kWh a year. At 12p per kWh that is roughly £711; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Canvey Island in winter?
It works, but the year is lopsided. 68% of a Canvey Island roof's output lands between April and September; the four months from November to February give about 1,170 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Canvey Island compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Canvey Island |
|---|---|---|
| Canvey Island | 1,079 | this town |
| Thundersley and South Benfleet | 1,070 | −9 kWh |
| Rayleigh | 1,072 | −7 kWh |
| Stanford-le-Hope | 1,074 | −5 kWh |
| Southend-on-Sea | 1,079 | level |
| Basildon | 1,068 | −11 kWh |
| Wickford | 1,069 | −10 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.
