I thought it was too expensive, so I decided to invest in solar panels. Solar panels on Rattana's water tower, along with the inverter, solar charge controller, and battery. Photos: Rattana SangcharernWorkers install solar panels on Weeraboon Wisartsakul's house. As previously mentioned, the on-grid system is when solar panels are connected directly to the transmission line run by the Metropolitan Electric Authority. If there's a loan system, I believe that people would take an interest in installing solar panels.
