Once the Spring arrives and I go out continuous cruising on the canals, I will need a way to generate electricity. Ideally this would be done without running the engine. Hence the installation of solar panels.
I chose 2 x 240W panels from Panasonic (model number VBHN240SJ25 if you’re curious) because they’re only 80cm wide which gives me extra walking space either side on the roof.
This is the video of that installation. See also my thoughts on solar during winter at https://www.youtube.com/watch?v=44uYIrs1RW0

This video shows how to make your own 10 cell battery pack using a BMS (battery management system) and a dedicated charger from an electric bike. This battery will use lithium ion batteries of the type 18650. As mentioned 10 cells connected in series, but also another 10 cell connected in parallel (10S2P).
