DIY solar panel made from polycrystalline cells 6x3 without making a frame etc.
It should have 36 cells, but i measured the glass too small, so proceeded to maintain 18v by adding 3 more half cells, Problem with this was the current was limited by half, so maybe should have left it at 33 cell and accept the lower voltage.
total cost to make €50 for glazing €50 cells + almost 2 hours soldering.
