The first step in calculating the inter-row spacing for your modules is to calculate the height difference from the back of the module to the surface. To do that, follow this calculation below: Height Difference = Sin (Tilt Angle) x Module Width ***Make sure you're calculating in degrees, not. . Wall collectors will probably be limited to 200 ft2 or less, and roof collectors will use the entire available roof area, perhaps 350 to 500 ft2. A standard rule-of-thumb is that the collector area should equal 1/5 to 1/4 the floor area in southern climates and 1/4 to 1/3 the floor area in the. . This online tool provides the you with the minimum distance to next solar collector and solar water heater system array to avoid inter-row shading.
