What is Net Metering
Net metering is a system that allows individuals and businesses with solar panels or other renewable energy sources to send excess electricity back to the grid in exchange for credits on their electricity bills. It enables solar energy producers to offset their electricity costs by using the grid as a virtual battery.
How Net Metering Works:
- Solar Power Generation:
Your solar panels produce electricity, which is used to power your home, business, or other property. - Excess Energy Sent to the Grid:
If your solar panels generate more power than you need at any given moment, the surplus energy is sent back to the municipal or national grid. - Electricity Credits Earned:
The power company credits your account for the extra energy fed into the grid, reducing your electricity bill. - Drawing Power When Needed:
At times when your solar panels aren’t generating enough power (e.g., at night or during cloudy weather), you draw electricity from the grid. - Final Billing:
At the end of the billing cycle, you are charged only for the net electricity used (total consumption minus the excess energy supplied).
Benefits of Net Metering:
- Lower Electricity Bills:
Reduces energy costs by offsetting the power you consume with what you generate. - Financial Incentives:
Some municipalities offer cash payouts for excess power sent to the grid. - Encourages Renewable Energy Use:
Helps integrate more clean energy into the power grid. - Efficient Energy Use:
Prevents wasted solar energy by redirecting excess production to the grid.
How to Install a Net Metering Device
Installing a net metering device is an essential step if you want to sell excess solar power back to the grid. The process involves setting up a grid-tied solar system, ensuring compliance with municipal or utility regulations, and installing a bidirectional meter to track energy flow. We offer this for residential, business and commercial uses. Contact us to get a quotation.
Net Metering in South Africa
In South Africa, net metering is being introduced in certain municipalities, with Cape Town leading the way through its “Cash for Power” program. This initiative allows households and businesses to register and sell surplus electricity back to the city.
