Are There Special Requirements for Businesses Using Net Metering?

Understanding Grid Tie Compliance

To ensure grid tie compliance, businesses using net metering need to install a two-way meter that can measure both the energy produced by the solar panel system and the energy drawn from the grid. The two-way meter is typically installed by the utility company, but the business owner is responsible for ensuring the meter is properly calibrated and functioning correctly. In the United States, for example, the Institute of Electrical and Electronics Engineers (IEEE) Standard 1547 sets the standards for grid tie compliance.

Utility Company Regulations

Utility companies have their own set of regulations and requirements for businesses using net metering. These regulations may include requirements for system size, interconnection time, and performance testing. For instance, Duke Energy, a major utility provider in the United States, requires businesses with solar panel systems to have a minimum system size of 10 kW and to perform annual performance testing. Businesses should review the utility company’s regulations and requirements before installing a solar grid tie system.

Record Keeping and Reporting

Businesses using net metering are typically required to keep accurate records of their energy production and consumption. This includes tracking the amount of energy produced by the solar panel system and the amount of energy drawn from the grid. The business owner may also be required to submit regular reports to the utility company, detailing their energy production and consumption. This information is used by the utility company to accurately calculate the business’s net metering credits.
