Collector performance is influenced by a wide range of parameters. In order for a system’s effective yield to be predicted these parameters must be known with accuracy. As a general rule the required accuracy can only be achieved by using outdoor measurements.
This is why SPF relies on several fully-equipped solar trackers. A solar simulator is also available for given measurements – in particular in the prototyping stage. A brief summary of the parameters developed for each collector (Solar Collector Factsheets) is available on our homepage. These performance indicators are also released in various formats on our SPF Info-CD, together with an exhaustive parameter statement and a collector yield calculator.
