How can I be sure matching solar is in the grid?

Absolutely! It is completely legitimate and authentic to claim you’re running on solar when you use SunJoules matched to power consumption. In fact, the underlying operating principle of our technology (consumption of RECs) is the only way to legally and legitimately claim use of any grid connected renewable energy. SunPort matches energy use against a true solar energy supply in strict accordance with what the US Federal Trade Commission (FTC) requires to legally claim use of solar energy.
