Knowing on how to build a solar panel is one of the first steps in order to have a solar powered home. There are basically 2 types of solar panels. First, normal panels use energy to do solar hot water heating for basic needs at your home, or even for your swimming pool. This normal panel acts as an absorber that converts the radiation from the sun into heat.
You can purchase solar cells online at auction sites or discount dealers. These cells typically have a flaw such as a scratch. However, it will still function properly. If you purchase the solar cells, you will have to construct a case for them to create the panel. Another fantastic and much easier option is to shop at your local RV dealer. They stock solar panels as accessories for the RVs. You will be able to purchase a panel for as little as $100. This way you will save a step since you will not have to build a case.
Useful solar panel reviews provide the P.T.C. and cost per panel, therefore you simply divide the P.T.C. by the cost. To illustrate a 250 Watt panel from ET solar carries a P.T.C. rating of 223.6 Watts. If the solar panel costs $250, then the P.T.C./Cost would be $250/223.6W = $1.12/Watt. The lower we can bring this number the better deal we certainly have found. solar panels in el paso tx are becoming more efficient and less expensive by the day, but on or after November 2012 a good target is $1.00/Watt or less.
Finally, to see how long it will take for your solar power home to pay for themselves, divide the cost of the cheap solar panels (minus the tax credit), and divide it by the amount of money you save per month. For example, that would be $2100 divided by $23.25. The result is 90 months, or seven and a half years. Or if you built your own with Earth4Energy your break even point will be considerably less and well worth looking into. Any money saved after that is pure return on investment.
Step 9 – Using some small screws, screw your solar cell panel into its box. Next, use silicone caulk to install the blocking diode inside the box. This prevents your homemade solar panel from discharging your battery when the solar panel is not at use i.e. At night.
Some feel that making their own solar panel is hard to do. This is just not true. With the right instruction and materials you can build your own solar panel not only in a short amount of time, but one that will work just as good as one that you buy already assembled. The materials are readily available online from numerous resources. The PV cells can be purchased in bulk, and these cells are just as efficient as any that are in panels already put together.
With your solar cells ready, you need a battery to store your electricity. The best option you have is to buy a rechargeable deep-cycle 12-volt battery which you can continuously used and store energy. A $50 battery should be sufficient to suit the needs of a small solar panel, with a battery box, for safety purposes.
For simple reference in regards to the difference between parallel and series wiring, just remember that parallel wiring = more amps, and series wiring = more volts. With a sound understanding of the differences between parallel and series solar installations, you are now ready to design and build your own solar panel system.
