Due to the rising costs and the shortage of fossil fuel, solar energy has been explored more than any other alternative source. Affordable solar panels created with silicon are more powerful; but being able to do it yourself can also come in handy.
Let’s see how you can build cheap solar panels on your own. The copper sheets will, first of all, need to be purchased and cleaned. Sandpaper is recommended for cleaning. Clean metal of all dust, dirt and oil. After scrubbing, use soap, water and a sponge to wash the copper. Be careful not to transfer any oil from your hands onto the copper. Dry the metal with a towel.

Turn the hot plate on to the highest setting and place the copper sheet onto the surface using the tongs. Heat the copper for approximately a half hour. The copper sheet will be ready when a layer of black oxide forms on the surface. Remove the copper sheet and let cool to room temperature.
Copper and oxide cool at a different pace. This will cause a separation between the two. The cooling oxide may send out sparks, so remove flammable objects and stay at a safe distance. The black layer will need to be removed from the metal by cleaning in clear water. The cuprous oxide, red in color, beneath the black layer will need to remain on the copper.
Fit the heated sheet of copper into a plastic bottle with an untreated sheet. Bend both heated and unheated metal outward so they will contact each other. Use alligator leads to clip the top of each sheet and connect the light meter. The untreated sheet of copper will need to be connected to the positive terminal and the heated copper connected to the negative terminal. As you can see do it yourself solar panels is not a very easy task.
To test your panel, mix 2 tablespoons of salt into clear water. Pour water into the plastic bottle until it is about an inch from the top of the sheets. Place the bottle in the sun and observe the micro-amps for temperature increase. Next, move the bottle to the shade for a decrease in temperature. Micro-amps should rise to about 50 in the sun and drop to no less than 40 in the shade. When in the shade, micro-amps should drop no less than 10 in temperature. You won’t be able to make big solar panels this way, but they would be perfect for demonstration purposes.
Following these diy solar panel instructions should create panels that would work very nicely where ever you decided to place them. I don’t think you will get best price solar panels if you make them completely from scratch, but it’s for sure a good project for a student.
