SIT wants to improve the energy and consequently the economic situation of the Tongan citizens, organizations and companies with an alternative solar source for energy, which can even generate the locally needed income.

SIT will develop, coordinate, execute and operate solar energy systems for private homes, schools and hospitals and commercial buildings in Tonga.


SIT shall further develop and install solar systems for charity projects. The operation shall be set up to ensure that all necessary know how is transferred to Tonga and that revenue generated from the sale of energy shall be reinvested to increase the production of solar energy. 


SIT will not compete but rather cooperate with the already existing local power production facilities. SIT is convinced that the advantage of self-consumption (i.e. lessen the burden on regional medium low voltage grids, reduction of Transportation of energy, supplying energy for peak times which ensures a good correlation between payer generation and energy on demand over time, it is future oriented and gives a good reputation). 


The power produced by SIT will be cheaper, more reliable and ecologically sustainable, therefore technically as well as economically well advanced. On the one hand the energy will be for self-supply of the house owners and on the other the excess will be sold to Tonga Power Limited (TPL). 


The facilities will remain property of SIT and after a certain period of time (approx. 6 years) the house owners will be granted the right of purchase for a highly reduced price. 


SIT starts with three pilot projects. The first three installations will be built for a school, a guesthouse and a farmhouse. All these buildings are strategically and geographically well positioned and will function and operate as show cases. 


In a second phase the constructions will be expanded to all areas of Tonga up to a total of one or more megawatt facilities. Eventually the facilities will be financed by the energy sell-off. All installations shall be set up to qualify for a CO2-Certificate. The sale of certificates shall generate an additional source of income. In case the model works it shall be expanded to other islands in the Pacific.
