HOW DOES NET METERING WORK IN SOLAR POWER SYSTEMS?

Net metering serves as a fundamental component of solar power grid-connected systems, facilitating a mutual benefit between consumers and utility providers. Under net metering, solar panel owners can send excess electricity generated back into the grid, receiving credits in return. These credits can then be applied against energy consumption during periods when solar power production is insufficient, such as night or cloudy days.

The net metering process typically involves the installation of a bi-directional meter capable of measuring both the production and consumption of electricity. At the end of each billing cycle, the utility company reconciles the electricity consumed against the electricity produced. If the solar energy generated is greater than the consumption, the homeowner receives credit towards future bills, effectively allowing them to store energy produced in excess. This system promotes the utilization of renewable energy while promoting economic fairness for both consumers and utility companies.
