Solar panels in York: what they generate and what they cost

A 4 kWp array in York should generate about 3,504 kWh a year on our modelling — 4% less than the median of the 1,356 places we model. Here is where that number comes from, and what it is worth.

About 3,504 kWh a year from a 4 kWp array, on our modelling for York.

That is 876 kWh for every kWp installed — 4% less than the median of the 1,356 UK places we model, and 23% below the sunniest.

What the number means

69% of the year’s output falls between April and September. April to September gives about 2,404 kWh; November to February gives about 568 kWh. That seasonal shape, not the annual total, is why solar cuts summer bills far more than winter ones.

The honest headline for anyone comparing towns: where you are matters much less than how your roof faces. Across every place we model, the spread from best to worst is about 54%. Turning a roof from south to north costs far more than that — see roof orientation and pitch and north-facing roofs.

The grant that pays for solar

York is a lead authority for the Warm Homes: Local Grant, on the department’s award list as it stood on 2026-07-02.

That matters more than anything else on this page for households that qualify, because the scheme’s guidance lists Solar PV among its eligible measures and permits a battery alongside it — as a grant rather than a loan. Eligibility runs on EPC band D to G plus an income, benefits or deprived-postcode route.

Apply through the council, never through someone who knocks on the door. Full detail: the Warm Homes: Local Grant.

What it is worth

Generation is not saving. What decides the money is how much of it you use as it is produced rather than export:

  • at 14% to 23% self-consumption — MCS’s figures for a household without storage — most of this output is exported
  • exported units earn your export tariff, which ranges from about 4p to about 12p
  • units you use instead avoid buying at about 26p

Put your own consumption in at the calculator, or read self-consumption for why it is the number that decides everything.

Before you get quotes

  1. Check the price per kW against the benchmark — divide any quote by the array’s kWp.
  2. Confirm the network position — G98 or G99 — and who your operator is.
  3. Check the planning position if you are in a conservation area or the building is listed — the planning cluster.
  4. Get three quotes and compare them properly — comparing quotes.
