Homemade automated solar concentrator▲296
Hi HN! I quit my job two years ago to have more time to work on my side projects. The main one is an automated solar concentrator. I've just open-sourced it, it's not perfect nor finished, and I still have a lot of ideas for further development, but I'm interested in knowing what you think of it. There are many applications where concentrated solar power could be a viable environmental and economic solution, I hope this technology will one day be more widely used. Feel free to give any feedback and ask questions.

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…
