How does solar net metering work?
We'll 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 have have the same buy back rate?
We'll in order for you system to make money for you in the form of savings electric companies must be willing to both buy and sell at an equal rate to max the savings a home with solar can see.
Just like the stock market your buying and selling, during the day your system is over producing and selling back to the grid. Then at night time your buying back, and we custom tailor your systems in order to sell more energy than your buying back and that is the reason why your able to receive negative electric bills, resulting in savings.
With a battery is net metering works by putting some energy you use, other you store in 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.
