Solar panel payback in Hull
How fast does a 4 kWp domestic solar system pay back in Hull, what does it save in year 1, and what's the 25-year net benefit? This page uses the same assumptions as our full solar calculator — only the local irradiance (PVGIS annual yield for the HU1 outcode) changes.
What makes Hull different
Hull sits on the drier east coast — yields beat inland Yorkshire by 2–3%.
The figures above use a 4 kWp south-facing system, no battery, 3,500 kWh/yr household use, 27p/kWh import tariff, 15p/kWh SEG export and 4%/yr electricity inflation — the same defaults as the full UK solar calculator. Yield here (920 kWh/kWp) is drawn from PVGIS satellite data for the HU1 outcode. If you want to model a battery, a larger system, east/west panels or a different tariff, open the main solar calculator — it accepts your exact postcode and full custom inputs.
Model it for your exact postcode
The numbers above assume the outcode HU1. For your postcode — which adjusts irradiance slightly — use the calculator below.
Other cities in Yorkshire
Solar yield varies more within a region than most people expect — coast vs inland, altitude, and overcast patterns all shift the numbers by a few percent.

| Leeds | 900 | £691 | 8.9 yrs | £21586 |

Getting accurate quotes in Hull
The calculator gives a tight estimate, but three local factors decide your real payback: roof orientation (south ≥ east/west by 15–20%), shading from chimneys, trees and neighbours, and installer pricing — which varies wildly even within a single city. Get at least three MCS-certified quotes before committing.
If you're also looking at batteries, check which UK Smart Export Guarantee tariff will pay you the most — it changes the whole payback equation. And if you're considering a heat pump alongside solar, start with the heat pump vs gas boiler calculator and the £7,500 BUS grant check.
