Roof Type and Orientation
Roof Type has a significant impact on your Solar Thermal Panels Performance especially when Panels tilt angle is the same as roof angle. In that case Panels Solar Azimuth can't be modified for peak annual or seasonal performance. Flat Roof offer the option of optimizing panels Tilt Angle and Solar Azimuth for best performance
Living Area (Square Footage)
The bigger the living area is, the higher Domestic Hot Water (DHW) and Space Heating/Cooling demands are. More Square Footage means more Bathrooms, Showers, occupants, Windows, Walls etc.... which translates into more KWh of energy spent every year. Larger size buildings offer a greater potential for Renewable and Semi-Renewable energy investments.
Maximizing Panel's Output
Solar Panel thermal Heat Output is maximized when the sun's direction is as perpendicular as possible to the panel's surface area. We measure solar panel orientation by its Tilt Angle and Solar Azimuth. The smaller the Azimuth is, the higher is the thermal energy output. Tilt Angle should be close to the geographical location altitude for a peak 12 months performance.
