Make a solar street light circuit board
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
Previously, we had built the Automatic Solar Light circuit and had been using it for many months. It has fair efficiency for everyday lighting. But this circuit has two problems: a dim light level and batteries that are hard to find and quite expensive. But now my daughter has built this Simple solar light circuit version II.
