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.

Hi HN! I’m Cole Ashman, founder of Pila Energy. I’ve spent my career working on home energy systems—first as an engineer on Tesla’s Powerwall, where I focused on the Backup Gateway, Solar Inverter, and metering systems. More recently, I led Product at SPAN, where we built the Smart Electrical Panel and integrated with most major home solar, EV, and battery systems. Pila (https://pila.energy/) is a home battery that plugs into a standard wall outlet, provides smart backup power, energy shifting, and grid services. It’s more than a power bank—it’s a distributed energy system…

Solar Witch is a little webpage and server which receives and displays messages, so I suppose it's a tiny message board. It's coded in very dubious Arduino C. It's not a 24/7 website. Depending on the state of the battery, the server itself might run all night, but all the messages it receives during the day are deleted at sunset, and the messaging function itself is only active between sunrise and sunset. This is for two reasons: 1. Less usage of Solar Witch during the night conserves battery power. 2. I like the idea of websites which _aren't_ constantly available. Websites which have…

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…
