We jumped into solar power on our 42' cruiser last year with the help of Patrick & Sherri Tasse from SunTech. They took the time to learn what our power needs really were, sized up the appropriate system and helped us every step of the way. We installed ourselves and Patrick answered all our questions quickly, during the process. We spent 18 days on vacation last summer and anchored every night. Our battery bank never went below 11.4V, even when we sat for 2 or 3 days. We couldn't be more thrilled with the performance, and just as excited about the professional and dedicated customer service we received. We highly, highly recommend SunTech for your best solar solution.
