Off-grid Solar Arrays are Independent of the Utility Power Grid.
In off-grid arrays, the solar panels generate direct current energy which is then connected to a Charge Controller to charge a set of batteries and stored in those rechargeable batteries. When energy is required, the direct current is sent from the battery to the stand-alone inverter and then converted into alternating current which can then be used to power a home or for any other electricity needs. These inverters are necessary for locations where no local power grid is available, or for anyone who wishes to remain completely independent of energy companies. It must be kept in mind that these systems are a very expensive option compared to the grid served electricity and comes up with a significant maintenance burden from the battery bank. With a stand-alone system, you will be unaffected by power outages because your system will be completely independent of the power grid. You will be free to consume electricity whenever you wish, provided your batteries are charged or your solar array is currently producing electricity
When the utility power is unavailable or too expensive to bring in to your home, solar panels allow you to be your own utility company! You can live in peace, with no noisy gas generator to disturb the quiet. There are several variations of off-grid solar power, depending on your needs and budget. All variations of off-grid solar power depend on solar electric panels, Inverter, and the stored electricity in the battery bank.
