説明

<p>The power demand of electricity growing very fast with high concern of climate change and environmental constrains. According to the Thailand Power Development Plan 2015 (PDP 2015) starting from 2015 to 2036, the national target of 30% of renewable energy to total energy consumption by 2036 is to be achieved. Solar photovoltaic (PV) is an important option makes the PDP 2015 meets the target. This paper aims to present the performance analysis of the solar PV rooftop system installed at Sakon Nakhon Rajabhat University. The system consisted of 1,016 polycrystalline silicon PV modules coupled to 13 units of 25 kW grid tied inverter. This system will be installed at the rooftop of the three buildings namely, the Central Building (CB), the Engineering Technology Building (ETB) and the Multipurpose Building (MB). The PV rooftop system is designed using PVsyst program. The PV modules faced tilts and azimuths with 5°/31°, 10°/31° and 5°/16°, respectively. The simulation results indicated that solar PV rooftop system can produce 452.92 MWh/year. The solar PV rooftop system could produce electricity generating from 06.00 - 18.00. The performance ratio of the system is 0.74. The Central Building has maximum power electricity generating as 44.44%. The Engineering Technology Building has high performance ratio because of its tilts and azimuths of solar panels that affect the irradiation. The solar PV rooftop can reduce the peak demand in time 06.00-18.00 of 13.24% and the reduction of greenhouse gas emissions is 263.65 tco2/year.</p>
