Our Journey
Siwasolar Energy Co., Ltd. reaffirms its strength as a leading distributor of solar energy solutions in Thailand, after being appointed and receiving the Certificate of Power of Attorney – Platinum Partner from LONGi, a global leader in solar energy innovation. This reflects LONGi’s confidence in Siwasolar Energy’s capability, credibility, and business standards as a strategic partner playing a key role in driving Thailand’s clean energy market forward.
The Certificate of Power of Attorney (POA) is an official document from LONGi that authorizes an appointed company to act as its representative and operate under the LONGi brand within a defined scope of authority. Receiving the Certificate of Power of Attorney – Platinum Partner therefore not only reflects Platinum partner status, but also serves as official recognition of Siwasolar Energy’s readiness to represent the brand in delivering products, technology, and services that meet LONGi’s standards to the Thai market.
Siwasolar Energy and LONGi presented this technology development direction at Asia Sustainable Energy Week 2026 (ASEW 2026), held from July 1–3, 2026 at the Queen Sirikit National Convention Center, showcasing clean energy innovations and solutions suited to every sector, drawing considerable interest from entrepreneurs, investors, project developers, and industry experts.
