How Hatfield compares
Among the places we publish figures for, Hatfield is one of 27 Hertfordshire towns we track, and it ranks joint 9th of 27 for solar yield. It is a medium town in the House of Commons Library classification, with 43,211 residents, and its roofs see 2.80 peak sun hours a day across the year. That drives the standard 12 panel model to 6,500 kWh of generation, of which around 5,563 kWh is exported at 12p for £668 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, defaulted to Hatfield's own yield, and at Hatfield's 1,022 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 Welwyn Hatfield; nationally, the House of Commons Library classes Hatfield 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.

A 12 panel, 6.36 kWp system in Hatfield generates around 6,500 kWh a year, worth around £914 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Hatfield's own coordinates (51.76209, -0.23287), 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 Hatfield
What could a roof in Hatfield generate?
PVGIS puts a roof in Hatfield at 1,022 kWh per kWp a year, 2.80 peak sun hours a day averaged across the seasons.
What does a typical solar system cost in Hatfield?
A typical 12 panel, 6.36 kWp system in Hatfield costs around £6,360 installed, at £1,000 per kWp before any battery.
Would a system in Hatfield 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 Hatfield before anything is booked; our G98 vs G99 guide explains the difference in full.
What could I earn from exporting in Hatfield?
On the 12p export scenario, that 12 panel system sends about 5,563 kWh a year to the grid, worth around £668. The tariff guide compares the export rates that could apply to your setup.

Why your inverter is smaller than your panel array, and why that is correct
More panel capacity than inverter capacity is a deliberate design choice.

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.

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.
