Solar cells are the instruments placed on solar panels that absorb the light and turn it into energy and electricity. Solar panels may save you a lot of money in the long run, but their plenty expensive to buy from a manufacture.
It might not be practical for everyone to take the efficiency out of their lives let alone the time to make each power cell individually. But for someone who lives out in the country who would just like a little electricity every once in a while for the most basic of reasons, building a homemade solar panel from home made power cells all from scratch is just another project to get done.
You can buy high efficiency solar cells at a radio shack, but that costs a lot of money even still. To build a total of 36 solar cells from scratch is cheaper than you think.
It takes 36 solar cells to fit onto a solar panel to generate eighteen volts; each individual solar cell being about a half volt. That is a total of sixty weights a day, and according to several of people who have experimented with the idea of homemade solar cells, the sun shines almost up to three hundred days a year on a good year.
Even for those extra days when the sun isn’t shining, you can buy a power storage battery that you can equip to your homemade solar panel. These store the electricity that is captured for rainy days. This is good enough to charge 12 volt batteries, which some people especially who live rustic lifestyles out in the country might find quite practical.
All of the materials you need can be find at any hardware or Radio Shack store. The items needed are, a sheet of copper flashing: Two alligator clip leads: A very sensitive micro ammeter that reads rather low voltages: An electric stove (has to be electric) A large clear plastic or glass bottle: A couple tablespoons worth of table salt: Tap water: Sand Paper: and finally shears for cutting the copper sheet. The instructions on how to build each solar cell can be found on any search engine like Google.
Solar cells can be extremely thin as paper and as brittle as glass. They are very sensitive to the elements so be extra careful. Instead of using silicon like a traditional solar cell Cuprous oxide, will be used as the conductor.
Once all of the solar cells are made, they must be placed on a solar panel, which can actually be as simple as a shallow wooden box that’s 3/4×3/4. Just place a piece of non reflective glass over the solar cells and your ready to go to follow the next set of instructions to set up the solar cells on the solar panels, which also can be found on any internet search engine.
Whether you want to be just more energy efficient, or make your own cheap as possible way to generate electricity, homemade solar cells and panels can be effective. The idea could even create a possible market for energy efficient green jobs for people who live in the suburbs who want a cheap solar panel but can find the time to make it.
Some people might find homemade solar equipment silly, but it could be quite practical compared to buying a highly expensive solar panel that would take hours, maybe even days to browse around for. Homemade solar panels are the next step of become self sufficient and energy efficient.
