Check out the video below to learn how solar electricity works in less than 5 minutes.
We can change sunlight directly to electricity using solar cells. Every day, light hits your roof’s solar panels with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current (“DC”) electricity. The electrons flow out of the solar panel and into an inverter and other electrical safety devices. The inverter converts that “DC” power (commonly used in batteries) into alternating current or “AC” power. AC power is the kind of electrical that your television, computer, and toasters use when plugged into the wall outlet.
A net energy meter keeps track of the all the power your solar system produces. Any solar energy that you do not use simultaneous with production will go back into the electrical grid through the meter. At night or on cloudy days, when your system is not producing more than your building needs, you will consume electricity from the grid as normal.
Your electricity provider will bill you for the “net” consumption for any given billing period and provide you with a dollar credit for any excess during a given period. You can carry your bill credit forward for sometimes up to two years.
In addition to selling electricity back to your utility, you can also store your energy for future use in whole home batteries. These are large rechargeable batteries designed for providing hours of electricity to your whole house.
