See what net metering is available from your utility and see what affect this has on the return you will get by installing a solar power system
|This estimator was developed in partnership with the US Dept of Energy.|
This Solar Calculator will compute the size and estimated cost to install a solar energy system for your home or building. The solar calculator's financial analysis is based on energy bill savings you can expect and the net solar system cost, after tax credits and other incentives are applied. The solar calculator results are based on many assumptions and the limited data you will enter. An actual site assessment by a trained professional contractor will be needed to determine the actual costs and benefits of installing a solar energy system.
NETMETERING AGREEMENT (for grid-connected PV systems)
Net metering means the utility company charges you the difference between what you consume from the grid and the electricity you generate.
This allows your electric meter to spin forward when electricity flows from the utility into your home (at night and during stormy weather), and backwards when your renewable energy system produces surplus electricity that is not immediately used by your house (during the middle of the day).
Most existing utility meters will work for net metering. But, you will need to establish an interconnection agreement with your utility company to get a net-metering account.
Your installer should handle much of this paperwork for you.
This agreement will ask you to demonstrate that your system was installed to certain building codes and electrical standards, prove that your system is insured, and show that your utility has access to a disconnect in case they need to shut your system down to service the grid --- line repair men need to be kept safe from your system when they are working on the grid.
Remember, we're all connected together through the power grid. The interconnection agreement helps make sure everyone�s power remains safe and of high quality and reliability.
Net Metering allows you to receive credit for the excess power you produce; you only pay for the net amount your home uses as provided from the utility grid.
We recommend you work with your installer, but provided below are links you can use to apply for Net Metering, or contact your utilty company to learn more.
General Information about net metering is available from the U.S. Department
Gross Metering is different from Net Metering. Gross Metering uses a Feed-in Tariff (FIT) structure: Some utilities offer Gross Metering instead of Net Metering. "Gross Metering" means that all the electricity you generate is sent to the utility grid for sale/reimbursement. It allows you to receive income (revenue) for the power you produce. Unlike Net Metering, the amount of electricity you purchase from the utility does not change to a Net amount = Home Use less Solar Production. Rather you receive revenue for having produced electricity and feeding all of it to grid: the utility or whomever the power purchaser of contract may be. Sometimes this revenue is received in the form of a credit on your electric bill rather than a separate payment.
