This research aimed to: 1) transfer pump system technology and pesticide heating pot booster by solar energy; 2) increase agricultural productivity and community income; and 3) analyze the break-even point between the use of solar technology and the original method. The research area was located in the public area at Moo 5, Tambon Nongchik, Borabue District, Mahasarakam. The researcher collected both quantitative and qualitative data to summarize the overview in order to cover both in-depth and broad dimensions of the research result. Data collection consisted of questionnaire, mind map, SWOT analysis, in-depth interviews, seasonal calendar, and observation. The information was classified according to the purpose of the study and then analyzed. The research found the community had the knowledge to understand how to use the tools; they were satisfied with the use of natural substances and interested in implementing it in the future. Experiments of pesticides extracted from solar energy by using herbs in the community found that pesticide heating pot booster power by solar energy could produce herbal extracts in a short time and was able to keep up with the outbreak of insect infestations. It did not require chemicals. This could reduce the cost of buying chemicals in the agricultural area of about 500 baht per plot. When compared to the area of 40 plots, it could save up to 20,000 baht. After 4 months of growing vegetables, they earn about 20,000 – 30,000 baht for their families. The break-even point analysis between the use of solar technology and the original method found the solar pumping system can pump 12,000 liters of water a day. The budget for this system is 120,000 baht; therefore, the break-even point was within 150 months (12.5 years). That was calculated from the deduction of water and depreciation at the age of 25 years. The break-even point of the pesticide heating pot booster by solar energy was 75-100 liters a day. That had a selling price of 35,000 baht. It could pay back within 1.7 months, when calculated from the depreciation of insecticides and depreciation at the age of 25 years. Nongchik Subdistrict administrative organization had an annual budget to support sustainability, strengthened and created a good reputation for the Banlaopho community, which was a pilot village and will extend to other areas.
