Division Formula 2

United Kingdom

s_{\bar{{mP}_{p}}} = \sqrt{\frac{\sum_{i = 1}^{n} {({mP}_{P_{i}} - \bar{{mP}_{P}})}^{2}}{n (n - 1)}}

Where:

s_{\bar{{mP}_{p}}}

Standard deviation of the arithmetic mean of the peak power output [W]

{mP}_{P_{i}}

Measurement value of the peak power output [W]

\bar{{mP}_{P}}

Arithmetic mean of the peak power output [W]

Number 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 $(s_{C_{{CO}_{2}}})$ . This value is to be calculated in accordance with Formula 3.
