Abstract
The aim of this paper is to present the results from the first assessment of a 20 kWp GCPVS in Ratchaburi, Thailand. The main objective of an assessment is to evaluate the grid connected photovoltaic technology, which operated under the hot and humid climate of Thailand. A 20 kWp GCPVS consists of 3 sub-arrays, monocrystalline, CdTe thin film and a-Si thin film sub-arrays, designed each to generate equally of 7.2 kWp. D.C. control cabinet and 3 grid connected type inverters. Technical aspect of each sub-arrays has been evaluated in terms of module efficiency, DC voltage and current and power, energy yield and performance ratio.Results from a typical day revealed that the DC electrical power of monocrystalline, CdTe thin film and a-Si thin film sub-arrays were about 5.724 kWh/d, 5.689 kWh/d and 4.890 kWh/d when the solar radiation intensity was about 7 kWi/m²/d. Results showed that the module efficiency of monocrystalline, CdTe thin film and a-Si thin film solar cells were about 9.78%,5.33% and 4.62% respectively.The energy yields and the performance ratio for each sub-array were in the range of 2.97-2.98 h/d and 0.56-0.57 respectively.
