The Solar Collector Factsheets are an SPF service. They include all relevant collector information as well as collector performance curves measured according to the EN 12975 and ISO 9806 standards. In order to objectively compare collectors, characteristic solar yields for the three most important solar applications are included.

  • Test reports and labels
  • Picture of installed collector
  • Contact address, regions of distribution
  • Technical details
  • Construction scheme with legend
  • Efficiency coefficients, angle factors
  • Solar yield calculations using Polysun for three standard applications: domestic hot water, water pre-heating, space heating
  • Measurement of pressure drop
