This study reports the evaluation of its electricity from solar energy. The format of the installation on the roofs of factories and residential areas connected to the distribution system, a Solar Roof Top Project 1 capacity of 17.9kW roof power plant appearance, inclined 17 degrees set in two years, the size of the project. 17.9 kW power plant on the roof looks tilted 13 degrees in the area of Lat Krabang, Bangkok. And three projects with a capacity of 20kW power curve creates a pool area. Located in Bang Na
Inverter (Inverter) used in the project is directly coupled system (Grid Connected Inverter) 3-phase 1 of the project. Power up to 20,500 W The system records and displays system hardware through the monitor screen of the inverter. (Inverter)
The results showed that as of October 1, the system can produce electricity from solar cells can be produced 899,000W 921,600W Project 2 and Project 3 951,400W produced by the photovoltaic power range. 09:00 to 13:00 clock the first period of the project include 7,200 w / m2 on two projects total 7,023 w / m2, and three projects total 6,606 w / m2 with a total efficiency of 11.25 percent, 10.97 and 10.16 respectively. Radiation Global Radiation based on information from the Meteorological Department Bangna area. In Bangkok, the three projects have different performance. With an average efficiency of photovoltaic cells in a characteristic pattern tilted 17 degrees, slightly higher efficiency in the range of 0.28 W / m² per cent and 1.09 W / m² respectively project. 1 and 2 of the investment can pay for itself in nine-month payback period of 6 years, faster than the 3 for 1 year and 1 month
1. To study the potential for electricity generation from renewable solar energy. The form of installing Solar Roof Top residential area and roof mounted plants connected to the distribution system (Grid Connected System)
2. To assess and analyze the pattern of installing Solar Roof Top.
