How Portishead compares
Among the places we publish figures for, Portishead is one of 21 Somerset towns we track, and it ranks 12th of 21 for solar yield. It is a medium town in the House of Commons Library classification, with 26,542 residents, and its roofs see 2.79 peak sun hours a day across the year. That drives the standard 12 panel model to 6,481 kWh of generation, of which around 5,544 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, defaulted to Portishead's own yield, and at Portishead's 1,019 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 North Somerset; nationally, the House of Commons Library classes Portishead 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 Portishead generates around 6,481 kWh a year, worth around £912 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Portishead's own coordinates (51.4819, -2.77586), 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.

Would a system in Portishead 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 Portishead before anything is booked; our G98 vs G99 guide explains the difference in full.
