Cramer added that the company continues to make its move into the residential solar market, where it has tremendous opportunity.
Not only does SolarCity gain customers via the homeowner, but in some areas it is also able to sell excess electricity back to the utility company that originally supplied power to the home.
SolarCity and NRG Energy (NRG), two competitors, are "knocking the ball out of the park" in this regard, Cramer said excitedly.
Solar prices have come down quite a bit, and Cramer continues to like SolarCity and First Solar (FSLR), despite the high valuation of the stocks. "It's a great business," Cramer concluded.
