All About Solar Panels

When it's bright and sunny outside, the sun easily provides enough energy to power a home, a business, a small village, or with a larger array, the only limitation is physical space and human imagination! Solar energy is free of pollution and does not rely on fossil fuels; it is a stable resource, for as long as the life of the sun. People are becoming increasingly aware of the damage our reliance on fossil fuels is for the earth, as well as beginning to understand that these fossil fuels will not last forever, and a different solution to our energy needs must be put into place.Energy costs have been on the rise, making people nervous when they get the electricity bill in the summer or winter. Solar panels completely remove the uncertainty and worry, and also substantially reduce the size of you and your family's carbon footprint. With solar panels, you will have a constantly renewing source of energy, and once they are in place, will require very little attention for twenty years. The value of a home is also considerably increased with the installation of solar panels.How Solar Panels WorkSolar PanelsSolar panels are made of solar cells, also called photovoltaic cells. When the sunlight strikes the non-reflective glass of solar panels, the photons from the sun interact with with elements inside the photovoltaic cell, shaking them up and causing electrons to separate from them. Electricity is created by this action, and then passes from the solar panels to a charge controller, which regulates how much electricity is sent to the batteries most homes opting to use solar panels have, so they'll have electricity through the night and on rainy days. The charge controller ensures long battery life by preventing the batteries from being either overcharged or over-drained.The electricity generated by solar panels and stored in the solar panels' batteries is direct current, or DC. The things in your home run on alternating current, or AC. An inverter switches DC to AC. After that, your home is powered very similarly to the way it has been by the electric company.Benefits of Solar PanelsNot that long ago, the cost of installing solar panels on a home was very expensive to start, even though the expense is recouped over the years; however, that cost has dropped more than 40%, and some states offer incentives and rebates for anyone who has solar panels. This makes it very easy to recoup your expense, sometimes in the first year!The best place to locate solar panels is on a southern-facing section of your roof; however, if you don't have southern-facing exposure, or it's limited, an east-west setting or a ground mounted system can work just as well. It's very important that there be no shade on the solar panels at any point during the day. There are very few homes that are inappropriate for solar panels: a combined approach solves almost all difficulties.
