As part of a project from “The Information Technology Foundation under the Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn (PSIT)”to provide life-long learning for communities in marginal areas, National Energy Technology Center (ENTEC) held a youth group activity “Do-It-Yourself LED Lamp Set” at 18th NSTDA Annual Conference (NAC2023) on 30 March 2023, 09:00-12:00, following the opening remarks by ENTEC Executive Director Dr.Sumittra Charojrochkul. The activity, supervised by Dr.Aswin Hongsingthong (project leader and researcher from Solar Photovoltaic Research Team), stemmed from the issue of lack of access to electricity, as well as lighting, in remote communities.
