研究目的
To evaluate the performance of a small-size photovoltaic plant and present some proposals for its optimization.
研究成果
The annual average electricity production estimated was 21% higher than the measured electrical production. For optimization, the use of strings with the same module type should be considered. The actual inclination (30o) is very near to the optimum (31.5o). Establishing a schedule with operational stops preferentially occurring in the winter period could improve the performance of the PV plant.
研究不足
The real losses in the plant (ohmic wiring loss and effect of dust) are probably higher than the estimated losses. The use of mixed types of modules in the same string increases mismatching.
