tool for standardized calculation of solar collector performance has been developed in cooperation between SP Technical Research Institute of Sweden, DTU Denmark and SERC Dalarna University. The tool is designed to calculate the annual performance of solar collectors at representative locations in Europe.
The efficiency of these collectors vary depending on the solar radiation, outside temperature, and collector fluid temperature. This simple calculator will give you an idea of the efficiency and output of a collector for the particular conditions you want to use it in.
Theoretical calculations As it was noticed, only a part of solar insolation on the surface of a collector is transferred into heat. The amount of this energy depends on the type of the solar collector and meteorological conditions of the place, where the collector is working.
Only a part of solar radiation striking the solar collector is converted into heat energy. The value and the intensity of solar insolation over a year, strongly depend on the latitude and weather conditions of the place. The heat energy produced by a solar collector depends on the type and design of the collector.
The use of the design tool for parametric analysis coupled with economical calculations can provide optimisation of the solar collector construction. Heat loss from absorber through glazing to ambient environment for solar collectors with low-emissive absorber (emittance 0.05) is around 75 % of overall collector heat loss.
The amount of this energy depends on the type of the solar collector and meteorological conditions of the place, where the collector is working. The average amount of heat energy produced by a flat plate solar collector during a day has been calculated by formula K – parameter, ̊C.

Calculating solar generation potential. We use the following assumptions to calculate solar generation potential in an ideal scenario: 850 square feet of usable roof space for solar: The average U.S. roof is about 1,700 square feet. You should never put panels on northern roof planes. So with a north/south roof, that gives you 850 square feet.
