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 could…

Hi HN, Shawn here. My rooftop system lost about half a year of production and nobody told me. Not the installer, not the monitoring app, not the utility. I found out from an electric bill that made no sense, then spent weeks digging through the monitoring portal by hand. SunRanker is what I wished existed that day. Connect a system once (Enphase OAuth, or a SolarEdge site ID plus API key) and it reads production daily, shows it in plain language, and emails you when something actually changes. Three alerts only. The connection broke, the monitoring went quiet, or output has been well below…
