In 1998 I wrote a financial summary for our ERP system (EUROnet) running on MS DOS with a dBase db in the backend. I've connected the dBase to a PHP 3 web server with Apache 1 and then summarized the sales data. My boss loved it. He could see numbers which are not implemented in the ERP reports.

Nice. This looks way better than this one written in Go: https://github.com/vdobler/ht it uses hjson.

We used it very often a couple of years ago. Will try hurl.

Yes that is the SBB in Switzerland but they do not turn the lights, instead they turn on the heaters for the track switches. Not sure if that is all rumours.

For solar excess charging I use evcc.io

When I charge the car via battery then only down to ~75% for now. The remaining energy is needed by the house during winter months.

Of course it is a bit oversized.

We’re living in a big river valley where we have fog from October until March. On some days in November the fog is so dense that the whole system does not produce any kind of energy. On the other days the produced kWh are enough to charge the battery.

We have a heat pump (extrem efficient), servers, one electric car, etc which consumes all together around 13MWh per year. The solar system produces around 27.5MWh. Most of the energy gets fed back into the grid.

We’re currently investigating to connect the neighbour houses physically to us. But that takes even more time here :-(

I did build my own solar system too. In Switzerland.

Took me 1-2 month planning and then 3 month building it alone nearly each day. Sept 2023 til Xmas 2023. Got all the hardware from a PV dealer friend on his purchase price level. Even 24 panels I have put myself alone onto the roof. With two persons it was a bit better.

I've got: 420w x 71 Trina solar panels and two SolarEdge inverters. SE10K Hybrid and a SE17k. Also a 24kWh BYD LFP battery.

All prices without state funding: Offers from local installers for 56*410W Panels without battery were around 65k CHF.

I've paid now 44k CHF including every kind of cost associated with building it.

Should write a blog post about it :-)

Next project is a solar fence with 6kWp.
