The key to solar is simple. Efficiency. Clean panels; free of dust, debris, and water spots are critical for efficient function of solar panels. Solar Panels should be properly cleaned and inspected 3-5 times a year depending on location. FabTech maintained panels have shown up to 30% increase in production due solely to receiving clean uninterrupted energy combined with well maintained connections and fittings. A FabTech Maintenance schedule could in fact be more influential to your utility bill than the panels themselves!
