# Commission Implementing Decision (EU) 2016/1926 of 3 November 2016 on the approval of the battery-charging photovoltaic 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), Division: Formula 2

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

smPp–=∑i=1nmPPi−mPP–2nn−1Where:
smPp–Standard deviation of the arithmetic mean of the peak power output [W]
mPPiMeasurement value of the peak power output [W]
mPP–Arithmetic mean of the peak power output [W]
nNumber of measurements of the peak power output, which is at least 5
The standard deviation of arithmetic mean of the PV roof peak power output leads to a statistical margin in the CO2 savings sCCO2. This value is to be calculated in accordance with Formula 3.
