N-Type and P-type modules of the same size can generate power of 560 W and 540 W in the front side, respectively, at irradiance of 1000 W/㎡. At the irradiance of 200 W/㎡, the performances of the N-Type and P-Type modules at low irradiance are known as 98.5% and 97%, respectively. Through calculation, we will have the front-side powers of the N-Type and P-Type modules: 560**98.5% = 110.32W, 540**97% = 104.76W. With the equation (110.32-104.76) ÷104.76×100% = 5.3%, we know that the energy gain of the N-Type module is approximately 5.3% higher than that of the P-Type module at the irradiance of 200 W/㎡.
