Length (mm)

Width (mm)

Printed efficiency (%), optional

Pmax temperature coefficient (%/°C, negative)

Cell temperature for the hot case (°C)

Warranty year to check

Efficiency = Pmax / (length x width) / 1,000 W/m². Hot power = Pmax x (1 + coefficient x (cell temperature - 25)). Year-N floor = 100% - year-1 loss - (N - 1) x yearly loss, as a share of STC power. The floor is a warranty minimum, not a forecast. The starting values are printed sheet values (see the page for sources); the 65 °C cell temperature is invented and the same for all three. Type 1722 or 1,722; 0.29 and 0,29 are read as decimals; 1.722 is rejected as unclear.
