The STC conditions are: 1 kWp is equivalent to 1,000 kWh per year. The average 1 kWp PV system in Germany generates 1,000 kWh per year. With a 7 kWp PV system, 7,000 kWh can be realized. These values vary by location.
Calculate the system’s Performance Ratio. PR = E AC / (P STC × H POA) PR = 720 / (6 × 150) = 720 / 900 = 0.80 A PR of 0.80 indicates the system is performing at 80% of its theoretical maximum, which is typical for residential systems considering losses.
