Make Your Own Solar Panel

Materials you will need The solar cell is made from these materials:1. A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.
2. Two alligator clip leads.
3. A sensitive micro-ammeter that can read currents between 10 and 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle.
4. An electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won’t work — mine is 1100 watts, so the burner gets red hot.
5. A large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work.
6. Table salt. We will want a couple tablespoons of salt.
7. Tap water.
8. Sand paper or a wire brush on an electric drill.
9. Sheet metal shears for cutting the copper sheet.
