SocketWatts guide

What plug-in solar can cost

Upfront cost, daylight use and an electricity tariff all change the outcome. Our estimate keeps these inputs visible instead of inventing a payback figure.

We publish this guidance for households in Great Britain. It is intentionally cautious because the decision depends on a complete product, its documentation, the mounting location and the electrical installation.

SocketWatts does not approve products or certify installations. If an answer is uncertain, pause and check it with the landlord, freeholder, manufacturer or a competent electrician as appropriate.
