I have discovered that prices have more than doubled in the last years on solar panels. I may have to modify my prices here. Years ago I was able to purchase solar panels for about $2 per watt. Now you are lucky to find them at $3-4 per watt. Most of them are around $5 per watt.

Therefore, I bought 50 solar cells from Ebay for only $99. I had to buy the flat connecting wire separately, bringing my total to $120 for about 87 watts of power at 12 volts. I am now in the very slow process of assembling my solar panels. I will make two panels in order to keep the size down a bit. The panels will be about 22 inches square each. Below is the picture of my cells.

This is the picture taken from Evergreens site on Ebay. Each cell measures 3x6 inches. The are extremely fragile and thin though, so this is taking a bit more time than I had originally planned. One cell puts out 0.5 volt at 3.5 Amps. This equals 1.75 Watt per cell. You need 36 cells to get 18 volts at 63 Watts. If you were to purchase the panel ready made, it would run you about $300 for this size.

Actually, for this test, I wanted to run 18 watts, which cost about $100 for a ready made panel.
