Abstract:

The traditional fixed adjustable bracket system uses a fixed adjustment strategy throughout its life cycle which means the number of adjustment time per year is unchanged in the whole life cycle. However, because of the degradation of PV panels and the increase of manual adjustment cost, the traditional method is not the optimal strategy. Based on the discounted profit and loss model, it analyzes and determines the reasonable adjustment method with the best economy based no the data of Golmud Project of Hefei Sunshine New Energy Technology Company Limited.The results show that adjusting 4 times per year in the first 8 years and adjusting 3 times per year in the following years of the whole life cycle can optimize the benefits.

Key words:

PV generation, insolation, the whole life cycle, fixed adjustable bracket, adjustable fixed bracket, economic analysis;profit and loss model
