Hello from Poland
Hello all,

I am really interested in EV, batteries and solar and I would like to start some projects.

I am renting a flat in Warsaw at the moment so I know it is not ideal but I want to start something : solar panels on the window sill + small battery for USB 5V output (few raspberry pi, charging smartphones and powerbanks....).

Happy to join the community Smile
Welcome, I believe a few here do a similar thing with panels in the windows and on the balcony -
