Direct Grid-Tie

Direct grid-tie systems operate in conjunction with the utility grid to achieve optimal efficiency. When the sun is shining and your solar electric system is producing electricity, the first priority is to power your household appliances. If a surplus of electricity is being produced, the solar inverter feeds any excess electricity back to the utility grid, making your utility meter spin backwards. (Must have a NET Metering agreement with your utility company)  This builds up a credit with your electricity company, reducing your bill, as well as increasing the amount of green energy on the utility grid. If enough electricity is not being produced by your solar electric system to power your household appliances, power is brought in from the utility grid to fill in the gap. All of this happens automatically without any need for intervention from you.
