It looks really, really tricky and probably expensive.

Buy an old window. Buy a large piece of copper the size of the window. Buy enough copper pipes and fittings to form an "S" pattern in the rectangle formed by the copper base plate. Spray paint all the copper pieces black. Sandwich the pipes between the glass facing the sun, and the copper panel as the backing. Run water through the pipes with a small pump. This is a very crude (probably tiny) solar hot water heater.

You really can't build your own solar cells, you have to buy them. $70 won't buy many, but you could make a very low power panel with $70 worth of solar cells. It would probably be cheaper to just buy a commercial unit though. Like the one in the source.

Take your 70 dollars to a store that sells solar panels. Buy the kit that says some assembly required. Thats it. Good luck.

Go outside and lie in the sun. You are a solar panel. Now go spend the $70 on beer.

Simple: google 'how to make a homemade solar panel' and be prepared to spend ome cash, although the investment could save you a lot in the future.
