We need electric power to perform our day to day tasks at home. Electricity companies are hiking up their rates every now and then. You have power everywhere but you are not harnessing it. One of the kinds of power available anywhere on earth is solar power but only a fraction of it is harnessed for useful purposes. Solar cell is the basic unit that is able to absorb the sun’s energy and convert it into electricity in order to make it available for use. Solar panels that consist of a number of cells are powering from tiny wrist watches to big water supply schemes in rural areas in developing countries today.
Since you know how a solar cell works you could use it to cut down the power bill of your home. There is the possibility for you to install solar panels to obtain the power you need for your home. However, you need to know the capacity of the panel you need to buy. It is easy to calculate the electrical energy requirements of your house. Simply add up the wattages used by each instrument and electric bulbs you use at home. In case you want to know how many kilowatt hours you consume in a month, you could get it from your electricity bill.
Solar panels that are available for domestic use come in three sizes of 4 inch, 5 inch or in 6 inches. Each solar cell is able to produce 2 watts and there are frames available in the market with 18, 36 and 72 cells in each. This means that they are able to produce wattages of 36, 72 and 144. When you calculate your energy requirements it is easy for you to decide how many panels you want. Once that is known, you could purchase the right number of panels and install on your roof. Though a single solar cell provides only 0.45 watts you have the option to buy panels to provide any amount of power.
Once you buy your solar cell panels you have the option to get them installed by an experienced electrician but even you could do it yourself. If you have a little know-how it is not difficult building your own solar panel. When you do so, you could save a lot. There is the possibility for you to buy a 72 cell solar panel with all the accessories for $100. Install one of them and save on your power bills.
