How Hoddesdon compares
Among the places we publish figures for, Hoddesdon is one of 27 Hertfordshire towns we track, and it ranks joint 14th of 27 for solar yield. It is a medium town in the House of Commons Library classification, with 41,605 residents, and its roofs see 2.79 peak sun hours a day across the year. That drives the standard 12 panel model to 6,474 kWh of generation, of which around 5,538 kWh is exported at 12p for £665 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Hoddesdon'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.
Hoddesdon sits within Broxbourne, its local planning authority, 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.

Connecting solar to the Hoddesdon network
On NESO's licence-area map, Hoddesdon is in East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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 Hoddesdon
A heat pump in Hoddesdon
Solar and a heat pump pull in opposite directions through the year: Hoddesdon's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,050 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Hoddesdon
From April to September, 68% of a Hoddesdon 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Hoddesdon solar questions
What could a roof in Hoddesdon generate?
PVGIS puts a roof in Hoddesdon at 1,018 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,470 kWh a year, most of it between April and September.
How much are solar panels in Hoddesdon?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Hoddesdon before a battery. What Hoddesdon changes is the return, about 6,470 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Hoddesdon?
Usually not in advance. UK Power Networks, the network operator for Hoddesdon, 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 Hoddesdon?
With typical use and no battery, a 12-panel system in Hoddesdon exports about 5,538 kWh a year. At 12p per kWh that is roughly £665; 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 Hoddesdon?
Yes, at a lower level. PVGIS gives Hoddesdon 36.6 kWh per kWp in December and 38.2 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 790 kWh in July. Winter output mostly covers daytime use rather than exporting.

| Waltham Abbey | 1,016 | −2 kWh |
| Harlow | 1,032 | +14 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
