What sets the SunMate apart from other solar panels is the design. One-piece construction produces a streamlined appearance that doesn't detract from your home's appearance. Heavy-duty, stainless steel and aluminum components result in quality construction that assures long life and virtually no maintenance. The SunMate is so easy to install - you can start enjoying the benefits of solar air heating in an afternoon! Includes a 10-year warranty! See Data Sheets section for details.
