John Grandinetti founded Grand Solar twenty-five years ago right here in Honolulu. That's one quarter century of continuous operation under one name, one address, one man with a spotless record. He has installed an average of 500 systems per year. He has trained half of the other solar guys out there since 1987. He knows solar better than anyone alive, and he personally supervises every single installation, like the one at your home or business. No other owner of a solar company with this much experience in Hawaii can guarantee that. Why hire the apprentice, when you can have the Master for the same price
