Plug-in solar panels (no electrician needed) have just become legal in the UK and will go on sale soon. Helios estimates how much electricity a typical installation could generate at a given address and what that's worth against your tariff.It uses UK government LIDAR data to reflect the actual skyline, so it knows whether there's a building or a hill blocking the sun.Caveats:
- Outside LIDAR coverage (most of Scotland and Wales) it falls back to a synthetic horizon (less accurate).
- Trees and recent developments (post-2022 or so) may not be in the data, and some address placements
