Estimate Solar Energy Generation for Any Location

Calculate how much electricity a solar installation would generate at any UK location based on irradiance and panel configuration.

Energy Data

Deciding whether to install solar panels means answering a question nobody around you can answer precisely: how much electricity will these panels actually generate here, at my specific address, facing my specific roof? Installer quotes vary wildly, and the estimates on most comparison websites are based on regional averages that ignore local shading, pitch, and orientation.

The solar_estimate skill calculates expected annual and monthly generation for a given location, panel capacity, and orientation. It uses actual solar irradiance data for the coordinates rather than regional approximations, giving you a figure you can trust when comparing against your current electricity bill or evaluating installer proposals.

Homeowners assessing solar viability, property developers planning new builds with solar, and energy consultants validating installer quotes all use this to get honest, location-specific generation estimates before committing to an installation.
