In general flat plat collectors always out perform evacuated tube in warm climates -- exception on overcast/cloudy days performance is about equal. 2. Warm Climate performance is indicative of when the fluid temperature entering the collector is 36 degrees warmer than ambient air temperature -- Approx. Ambient Temps above 50 degrees. 3. Cold Climate performance is indicative of when the fluid temperature entering the collector is 90 degrees warmer than ambient air temperature -- Approx. Ambient Temps below 50 degrees. 4. On an annual basis, flat plate collector systems provide more energy due to increased performance when the sun is out and it is not cloudy. SOLAR ENERGY Advantages of Flat Plate vs E Vac Flat Plate Collector is more Durable Resistant to Damage Flat Plate Collector is easier to clean and keep free of debris Flat Plate Collector is more Aesthetically Pleasing in Appearance Flat Plate Collector can be Roof Deck Mounted for a Very Low Profile Which Units Instill Confidence in You and Would you place On your Home ??
