The 3 terminal voltage regulator you have pictured, which I gather is a typical LM7805, is only good for 1 amp with adequate heatsinking.
Best place to find cheap heatsink is out of an old TV you find on the side of the road.
You are better off using one of those little switching modules we got from China. (buck one for going DOWN in voltage).
Sorry don't have a picture. I think they were like less than $2 each with free postage.
They will supposedly handle more current, and will be far more efficient as well, and with solar you need efficiency.
