GO GREEN - Go Solar in Tonga!

We’re committed to increasing solar energy in Tonga. There are roofs all over the islands that could become renewable energy generators, and a huge opportunity for growing solar for our community.


We’re excited to be leading the charge and partnering with Tonga Power Limited to help get there and proud to be helping Tonga gain access to energy that is cheaper, safer, and better for the environment.

There is no better time than now to switch to clean, green renewable solar energy!

Green energy – a sustainable way to do business

Here are some insights into current Energy solutions within Tonga 


Current reliance on fossil fuels

The majority of Tonga’s electricity generators are supplied through imported fossil fuels leading to high and volatile energy prices and a negative impact on the environment. Small rises in oil prices have a significant impact on national revenue as the government limits electricity price raises. Furthermore there are high transmission and distribution costs (estimated at 18%) due to poor infrastructure (primarily lines, meters, transformers) and environmental costs.


High cost of electricity

The price of energy in Tonga depends on the price of oil, energy is expensive and too much of a burden for its population and its economy. Many households can hardly pay for the electricity and the schools and other public institutions often lack power completely due to insufficient funds for the bills. The same applies to people running a business in Tonga. Often their margin is eaten up by the high energy prices. 


No incentives to go green
Nations like Tonga are often too small for both an interest of other governments for a strategic investment and for companies to enter the market. Finally, there are insufficient funds and incentives available to initiate the “solarisation of the private sector”, i.e. to motivate local families, institutions and companies to go the solar way.


A move to renewable energy

Nevertheless, the Kingdom of Tonga is planning to move forward with its energy policy and the Implementation of Tonga Energy Road Map (TERM) with a goal of 50% renewable energy by 2020. It wants to be part of the technological development of renewable and sustainable energy and improve their energy supply. 


A proven trusted team to help Tonga GO GREEN
Solar Island Technology 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 set up an organisation for the promotion and operation of solar energy production in Tonga and neighbouring islands of the Pacific.
