How Harlow compares
Harlow is one of 46 Essex towns we track, and it ranks joint 38th of 46 for solar yield. The House of Commons Library settlement data classes it as a large town of 98,155 people. At 1,032 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.9 years on the 12p scenario: £922 of year one benefit against £6,360 of installed hardware, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Harlow's own yield, and at Harlow's 1,032 kWh per kWp it 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 here go through Harlow; nationally, the House of Commons Library classes Harlow as a large 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.

A 12 panel, 6.36 kWp system in Harlow generates around 6,564 kWh a year, worth around £922 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Harlow's own coordinates (51.76778, 0.10833), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.

Common questions about solar in Harlow
What could a roof in Harlow generate?
PVGIS puts a roof in Harlow at 1,032 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons.
What does a typical solar system cost in Harlow?
A typical 12 panel, 6.36 kWp system in Harlow costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Harlow need a G99 application?
Most home solar and battery systems qualify for the simpler G98 notification, made to the network operator (DNO) after installation rather than before. A minority, usually larger systems, need the fuller G99 process instead. Your design call checks which applies in Harlow before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Harlow?
On the 12p export scenario, that 12 panel system sends about 5,627 kWh a year to the grid, worth around £675. The tariff guide compares the export rates that could apply to your setup.
