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. Consumption during the day is provided by solar energy collected and any excess energy collected is sold back to the energy company (the grid). At night and when you are not generating enough solar power to sustain use, energy is provided from the grid. Individuals who utilize the grid tied system and produce 100% of their annual energy needs by way of solar energy will see large credits to their utility accounts during the summer months when excess energy is provide by the sun and they are selling energy back to the grid. These large credits are then offset by bills encured during the winter months when they need to take energy from the grid to meet their consumption needs. Currently, many states are offering rebates and incentives to individuals who install a grid tied system to their homes.
To make your gried 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. Prior to excess solar energy being sold back to the grid, energy charges the battery system for use when the grid goes down. The operation of lights, heating, computers, refridgerators, pumps, fire & security alarm systems and other equipment is maintained until utility power is resored. With this system, power is only utilized from the grid when your battery back up system is empty and you save even more money on utility bills.
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.
These systems may qualify for rebates or tax credits through current federal, state, and local renewable energy programs.
