Thailand Solar Installer Alliance (TSIA)

Statement of Purpose

The Thailand Solar Installer Alliance (TSIA) is an independent, nationwide network of solar installers, electricians, engineers and renewable-energy advocates. We came together because the people who put solar on Thailand’s roofs deserve a community that shares knowledge freely, upholds high standards and stands behind its members.

Our visionEvery solar system in Thailand is designed and installed safely, correctly and to recognised standards, by trusted installers who are fairly rewarded for good work.

Our mission

1. Share knowledge, not sales pitches.We give installers an open forum to exchange technical know-how and solve installation engineering problems correctly and to standard. TSIA is a community for learning, not a sales channel.
2. Connect people with installers they can trust.We identify qualified, reliable installers in every region and pass work between members by recommendation, so customers are served by people the alliance vouches for.
3. Stand behind our members.We help resolve disputes arising from installation contracts and give solar installers access to legal advice, so no member faces a dispute alone.
