WebMar 11, 2024 · The solar array mismatch loss is expressed in the percentage of the total array output. For example, if an array has a mismatch loss of 0.5% and the total array output is 1000 W, then the mismatch loss would be 0.005 kW (0.5% x 1000W). The solar array mismatch loss can be a significant contributor to overall system losses. WebMismatch loss is determined by the following equation: Mismatch Loss = –10 log(1 – ρ 2) Where ρ is the reflection coefficient. For example, a filter with VSWR of 2:1 would have a reflection coefficient of 0.333, a mismatch loss of 0.51 dB, and a return loss of 9.54 dB (11% of the transmitted power is reflected back). hermant mandal
