# Commission Implementing Decision of 18 November 2014 on the approval of the battery charging Webasto solar roof as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) (2014/806/EU), Division 2: The testing procedure

Extent: E+W+S+N.I.

The peak power output (PP) of the PV panel is to be determined experimentally for each vehicle variant. Measurements are to be done in accordance with the testing methodology specified in the international standard IEC 61215:2005.
A dismantled complete PV panel is to be used. The four corner points of the panel are to touch the horizontal measurement panel.
The measurements are to be done at least five times.
The lengthwise inclination angle and total storage capacity (or resulting Solar Correction Coefficient (SCC)) is to be supplied by the manufacturer of the vehicle.
The possible lengthwise inclination of the car roof is to be corrected mathematically afterwards by applying a cosine function.
