Solar Power Plant

Due to global warming, people become more aware of renewable energy and alternative energy instead of fossil fuel. Ministry of Energy has issued the Power Development Plan/PDP 2010 revised edition 3 (2012-2030) setting the proportion of electricity from renewable energy for up to 9,481 MW at the end of 2030, especially the production of electricity from solar energy is targeted at 2,000 MW by the year 2021.

Solar energy is a natural energy that is clean, pollution free and is renewable energy with high potential especially for electricity production. Solar potential according to the Department of Alternative Energy Development and Efficiency and Faculty of Science, Silpakorn University found that the distribution of the solar radiation intensity in areas of the country for each month is significantly influenced by the northeast monsoon and southwest monsoon. Most areas of the country receive maximum solar radiation during April and May with values in the range of 20 to 24 MJ/m2-day. When considering the daily average of solar potential map in a year, the area receiving the highest average annual solar radiation is in the Northeast. covering some of Nakhon Ratchasima, Buri Ram, Surin, Roi Et, Yasothon and Ubon Ratchathani and Udon Thani as well as some parts of the central in Chainat, Nakhon Sawan, Ayutthaya, Lop Buri, and Suphan Buri with the average annual solar radiation 19-20 MJ / m2day. Such areas representing 14.3% of the total area of the country. It is also found that 50.2% of the total area receives an annual average solar radiation in the range of 18-19 MJ/m2-day, mostly in the Northeast and parts of the central region. The result shows that Thailand has a relatively high solar potential.
