Yes. Except in the rare circumstance where you decide to buy solar plus energy storage and become 100% “off-grid”. Because of the way you generate most of your solar energy between approximately 10 a.m. and 3 p.m. most days, you will always need to buy some energy to power your home every moment of the 24 hour day. The principle of net metering was established as means to address this timing offset and establish value for you generated power. Please visit our calculating solar savings page to learn more about what to expect in your monthly bills.
