Collector performance

During winter an in periods with lower solar irradiations often only 400W/m2 are available. The temperature differences between collector and outside are very high. In the chart below you will find out how the energy performance of the collector changes according to the solar irradiation and temperature differences. The values are considered under direct irradiation.
Collector output per module [W] OPC 10 radiation power

Dimensioning of collector areas, solar tank and heat exchanger

In the following chart you can see recommended values for the dimensioning. In any case we recommend to use simulating software to calculate the energy yield and layout of your solar system.
