Abstract

The standard EN 12975-2 provides guidelines for testing solar collectors both in stationary and quasi-dynamic conditions. The second test method allows the optical efficiency of flat-plate collectors and even evacuated tube collectors to be determined by applying the extended multiple linear regression. However, in the case of tubular shape collectors, the available procedure requires a large number of data, above all for the determination of the transversal incidence angle modifier, which is the parameter describing the optical response of the absorber tube to the direct beam on the plane normal to the tube axis. Here, an improved procedure to determine the transversal incidence angle modifier is presented and validated against experimental data.
