Solar charger for Dewalt and Ryobi power tool batteries

Great little project ,one heck of a little power plant

The battery is to store the energy from the panel. Running directly from solar will be too erratic as the sunlight comes and goes. With a 50 watt panel you can charge a 20 Ah battery in about 5 hours of full sun, The 20Ah battery is enough to charge 1 or 2 18 volt power tool batteries.

Where did you get your supplies from?

I was trying to figure out the watts needed for an 18-volt, but 50 watts does it, huh?

How much did all this cost?
