How much sun does Worcester get?

Worcester averages about 4.0 peak sun hours a day, more than 53% of the 123 cities we track. As a rough guide, each kilowatt of panels here makes about 1,160 kWh a year (after typical system losses). A good installer will give you a roof-specific estimate that accounts for shading and roof angle.

Source: Open-Meteo historical solar radiation, 2020-2024. Production estimate assumes 80% system efficiency.

Before you hire a solar installer

  1. Ask for a production estimate for your roof (kWh per year) and how shading was measured.
  2. Ask which panels and inverter they use, and who backs the warranty if the company closes.
  3. Ask how your utility credits extra power you send to the grid, and whether a battery makes sense for you.

Before you call anyone, check what solar rebates you can get in Worcester. Many programs require approval or a registered contractor before work starts.
