How does solar net metering work?
When a home owner first gets a solar panel system they have to check if their current electricity provider currently provides a buy back program, which allows solar owners to both sell and buy electricity. Some electric companies have different rates, Green Mountain for example, provides a equal buying and selling rate.
Why is it important to have the same buy back rate?
Because in order for the system to make money for you in the form of savings electric bills, companies must be willing to both buy and sell at an equal rate to maximize the savings a home can produce with solar.
Just like the stock market you are buying and selling, during the day your system is over producing and selling back to the grid. Then at night time you are buying back, and we custom tailor your systems in order to sell more energy than you buying back and that is the reason why you are able to receive negative electric bills, which results in savings.
When a battery is installed, net metering works as putting some energy you use into your home, other you store in the battery and the rest you sell it back to the grid. This is to ensure when in the event of a power outage your battery kicks in and is able to back up your energy usage during it.
