Solartech Permanent Magnet Solar Pump Applied in Thailand Solar Dairy Farm


Location: Bangkok, Thailand


Introduction: 80% of Thailand’s population are farmers. Thailand enjoys the title of “Southeast Asia Granary”, it is the only one grain net exporting country in Asia. The going high diesel price is challenging the production costs, product prices and the income & consumption of farmers, which affects the Thai agricultural output. Solartech high reliable and efficient SPM permanent magnet solar pumps (DC brushless motor solar pumps ) brought a new hope for Thai agriculture.


Solution: In 2014, Solartech SPM600C solar pump was installed in Bangkok, the system can produce water 18m3 daily at 18m water head for people and livestock in the dairy farm. Comparing with traditional 3 phase AC induction motor pump, Solartech permanent magnet solar pump can provide same performance using 20% less solar array, which effectively reduced the cost of solar pumping system, the investment recovery time is only 3 years. The combination of solar and agriculture can solve the energy problem in agriculture production, it can speed up the reform of Thai energy structure.


Economic Benefits: 1,664kWh of electricity generated annually; 16 tons of coal saving in its 25-year service life; 7 tons of CO2, 0.3 ton of SO2, 0.2 ton of smoke and 4 tons of ash reductions in its 25-year service life.


According to World Development Indicators 2011 published by World Bank, every cubic meter of water consumption could contribute 2 USD to Thailand's GDP, in the system 25-year service life, over 164,000 cubic meters of water can be produced by solar energy for drinking water supply to people and livestock.
