The investment and technical analysis of solar power plant development case study in Mukdahan Province, Thailand
Abstract:
This research presents both investment and technical aspects of solar power plant. The one mega-Watt solar power plant, located in Mukdahan province, Thailand, is used as case study. The right process is proposed. Both economic and technical is considered. Interested parameters consist of investment cost, solar radiation, power energy, PV module, type of inverter, environmental impact, area size and the grids connection. PV module must be indexed by 1st tier manufacturing and workmanship warrantee is more than 10 years. Degradation grad warranty must be less than 0.8% per year in the term of long period 25 year. It is not over 20% along period. Inverter type must be pure sine wave grid connected and it should have warrantee from original manufacturing 5 years above and indexed by 1st tier. The area size should be more than 7,000 m2. The site location must not be obstructed by building, trees, or tall objects. The site must not be prone too dust and rain. The area must be flat and not prone flood. The plant must be near connecting grids and sufficient grid capacity. From the result of case study (Mukdahan plant), it shows average output power energy is 1,506,000 kWh/year. In conclusion, it is found that project has equity internal rate of return (IRR) is more than 13.5%. The surface solar radiation is more than 4.1 kWh/m2/day. The power energy after Commercial Operation Date (COD) has performance ratio is more than 76.26% (PR ratio).
