Gunkul Megasolar

Thailand-based Gunkul Engineering has seen almost continuous growth since its founding in 1982. It is active not only in Thailand, but in international markets including Laos and Vietnam. Its strong expansion can be attributed to its relations with overseas firms, and its initiatives with new technologies, including solar power.


Following an agreement with the Provincial Electricty Authority (PEA), Gunkul is undertaking a 7.4 megawatt solar power plant project to be constructed in Phetchabun, located in the north of Thailand. The project will be conducted in two phases, with the first phase being a three megawatt installation. Solar Frontier has provided the panels and Schneider Electric will handle the installation.


Solar Frontier’s CIS technology was chosen over other PV types due to their ability to handle the high ambient heat of the region, where the average annual temperature reaches 28 °C (82 °F). The first phase of the project began producing electricity in January 2011.
