About us


Solar Island Technology (SIT) Ltd.

We have formed a Swiss, German and New Zealand team with Tongan family roots and experience in both Tongan government and investment activities to bundle our know how, energy and funds to promote and operate a solar energy production in the private sector, focusing on small-medium enterprises and institutions. 


SIT is open for everybody who is interested in sustainable projects, who wants to have full transparency and reliability and finally who wants to support and not just donate.


The SIT project is backed and approved by two Swiss Foundations and by PlanetSolar http://www.planetsolar.org.
