Grid Tied
Thousands of utility grid tied homes are now employing solar, wind, and turbine energy to augment or minimize the use of local energy companies. These systems can run with or without a battery backup. People who choose to run grid tied systems without a battery backup cannot use their solar power system when utility power is not available. If utility power goes down, so does the power in a grid tied only system. This type of a system will offset your utility usage, but will not aid in keeping the lights on.
During the day: Electricity consumption of the property during the day is provided by solar energy collected on the roof. Any excess energy collected is sold back to the energy company (the grid) to offset the electricity usage overnight and on cloudy days. When Cloudy or Nights :There will be times when you are not generating enough solar power to sustain use, or any at all. During these periods, electricity is provided from the commercial power grid to power your property. Individuals who utilize grid tied systems and wish to produce 100% of their annual energy needs by way of solar panels, will see large credits to their utility accounts during the summer months when copious amounts of energy is provided by the sun. The excess energy is used by others as they are selling energy back to the grid. These large credits are then offset by their larger heating bills during the winter months. This allows these individuals to take back the energy when they need it, so long as the grid is functional. Currently, many states are offering rebates and incentives to individuals who install a grid tied system to their homes. To make your grid tied solar powered system even more effective, combine the system with battery back up power. In event of the grid power supply going down, your system will still have power supplied by the battery back up to the property. With solar battery back up power as part of your system the operation of lights, heating, computer, refrigerator, pump, fire & security alarm systems or other equipment is retained until utility power is restored either on a selective or wholesale basis. In addition the batteries will be charged prior to excess solar energy being sold back to the grid. The batteries maintain this service and serve three other functions for your property you may or may not even be aware of. These systems may qualify for rebates or tax credits through current federal, state, and local renewable energy programs. |
