How Barnet compares
Barnet is one of 23 Middlesex towns we track, and it ranks 23rd of 23 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 404,081, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and on the 12p scenario about £247 of the year one benefit comes from solar you use yourself, with export income adding £663.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Barnet'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.
Planning applications in Barnet go to its own council, and the House of Commons Library classes it as a core city.
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.

Connecting solar to the Barnet network
UK Power Networks owns and runs the local electricity network in Barnet, as part of its East 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 UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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.

Heat pumps and EV charging in Barnet
A heat pump in Barnet
Solar and a heat pump pull in opposite directions through the year: Barnet's roofs make 1,130 kWh from November to February on a 12-panel system, and 3,030 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 Barnet
From April to September, 67% of a Barnet roof's yearly output arrives, peaking at about 790 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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.

Barnet solar questions
What could a roof in Barnet generate?
PVGIS puts a roof in Barnet at 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,460 kWh a year, most of it between April and September.
How much are solar panels in Barnet?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Barnet before a battery. What Barnet changes is the return, about 6,460 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Barnet?
Usually not in advance. UK Power Networks, the network operator for Barnet, 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. 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. "See our DNO explainer.
How much can I earn from exporting solar in Barnet?
With typical use and no battery, a 12-panel system in Barnet exports about 5,525 kWh a year. At 12p per kWh that is roughly £663; 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 Barnet?
Yes, at a lower level. PVGIS gives Barnet 36.9 kWh per kWp in December and 39.8 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 790 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Barnet 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 Barnet |
|---|---|---|
| Barnet | 1,016 | this town |
| Borehamwood | 1,015 | −1 kWh |
| Haringey | 1,024 | +8 kWh |
| Brent | 1,024 | +8 kWh |
| Camden | 1,026 | +10 kWh |
| Enfield | 1,025 | +9 kWh |
| Harrow | 1,026 | +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.
