Understanding Solar PPA in Thailand: A Complete Guide for Businesses
What is Solar PPA? A Power Purchase Agreement (PPA) is the easiest way for Thai businesses to go solar. With a PPA, a solar company installs panels on your rooftop at zero upfront cost. You simply buy the electricity they produce at a rate lower than what you currently pay the grid. How Much Can You Save? Thai businesses typically pay 4-5 THB/kWh from PEA/MEA. With a Solar PPA, you pay around 2.50-3.00 THB/kWh — saving 20-40% on electricity costs from day one. PPA vs Buying Your Own System If you have capital available, buying your own solar system (EPC model) offers higher long-term savings. A typical 500kW system costs ~15M THB and pays back in 4-6 years, with 20+ years of free electricity. Not sure which option is right?
