What it does

Helios by South London Scientific helps UK residents determine the viability of plug-in solar panels for their homes or balconies. Users input their postcode, floor, balcony direction, and electricity usage to receive personalized energy generation estimates. The tool leverages Ordnance Survey, LIDAR, and PVGIS data to calculate potential yield, considering shading from surrounding buildings, without storing personal address information. This helps users understand if plug-in solar is a worthwhile investment before the technology becomes widely available.

Who it helps

Homeowners and flat residents in Great Britain considering installing plug-in solar panels on their balconies or properties. Specifically, those interested in understanding potential energy generation and cost savings before committing to an installation.

Why it's interesting

Helios addresses a clear emerging need as plug-in solar panels become available in the UK, offering a data-driven way to assess viability. Its use of LIDAR and PVGIS for accurate, address-specific shading analysis provides a valuable, privacy-focused service. The tool positions itself well ahead of the anticipated mid-2026 safety standard, potentially capturing early adopters.

Helios is a highly polished and technically sophisticated tool that addresses a clear emerging need for plug-in solar panel assessment in the UK. Its use of LIDAR and PVGIS for accurate, privacy-focused yield estimates provides significant value. The estimate reflects the strong product clarity, technical execution, and early positioning in a growing market. However, without any visible monetisation strategy or explicit traction, the valuation is constrained, as it currently appears to be a valuable free utility rather than a revenue-generating business.
