Been messing around with the solar cells I got from China.
My first efffort was all nicely laid out on a board , when it fell off and got alot of cracks and broken wires , so I ended up laying a sheet of fibreglass on a plastic sheet , pouring a load of hardener / resin , on the fibregalss and laying the cells on top , it works and produces between 16-18 colts .
My second effort ( better looking one )is a panel with 6 rows of 4 cells and produces 12.8 ish overcast and 14 volts sunny.
I do have a basic controller which I will be getting plugged in at the weekend.
Here is a 2min video showing the panels.
