Abstract
A one year performance of the 9.8 kWp photovoltaic roof top grid connected system techno evaluation presents in this article. The system has been installed in the northern Thailand. The 3.5 kW of single phase grid tie inverter per system has been applied at PV system. The 3 PV systems had been mounted on the single roof of household at various orientation. The first PV system had mounted on the south and west roof with 6 panels on each direction and connected in the series by 280 Wp PV per pannel. The second and third PV system was mounted on the west and the east with 12 and 11 panels respectively. The total PV system was 9.8 kWp with 10.5 kW grid tie inverter. The experiment was designed by IEC 61724 to guide line the technical parameter and analysis the system. The result found that the an average solar irradiance yearly on tile around 5.65 kWh-day, the performance ratio is rage 70-80% around year and the utilization factor or final PV system yield in range 3.42 - 3.6 kWh per kWp. The direction of PV as mounted on household rooftop have had influenced with the AC energy output. This results can be applied not only system performance analyze but also the guild line to any roof top utilization. ฉ 2016 IEEE.
