Abstract:
This thesis presented a comparison of performance analysis between simulation program
and real installation data of a 6 MW PV power plant in Prachin Buri province. Thin-film solar panels
which were sensitive to radiation fluctuation in a wide range, were selected for the PV power plant.
The performance analysis will be used for an investment and an economics analysis of the PV power
plant.
Comparison analysis of power generation performance was investigated by using data of
PVsyst simulation program and actual power generation capacity in the year 2016, 2017 and 2018.
Relative Error Analysis was applied to consider the deviation from PVsyst simulation program and
actual power generation of the PV power plant.
The study results showed that in the year 2016, 2017 and 2018, the total power generation
capacity obtained from the PVsyst simulation program was higher than the actual power generation
capacity. The actual power generation was lower at -2.89%, -5.75% and -7.2% respectively. The
results of the study suggest that in order to make a decision to construct a PV power plant, it is
necessary to ensure that the power generation capacity of PVsyst simulation program is lower than
the actual power generation of PV power plant.
