Siam Sun Information

We provide solar energy with no upfront costs, enabling Thai SMEs to reduce energy bills, lower emissions, and support the local economy. At Siam Sun, we believe that the energy transition is powered by every participant, especially the SMEs that form the backbone of the global economy. While larger corporations often have easier access to renewable energy, our mission is to make clean power accessible to everyone. Thailand imports over 50% of its energy, with just 5% from solar despite abundant sunshine. While energy demand grows and fossil fuels continue to dominate the global energy supply, contributing to climate change and air pollution, it’s clear that a just and sustainable energy transition is not only necessary but also urgent. We focus on generating power where it’s used, harnessing the sun's energy. With more than 12 years of experience in Thailand’s solar industry, we’re proud to be trusted by embassies, multinational clients, and both Thai and U.S. government projects. Join the solar revolution, and meet us on our website!
