RFQ-TP24-007 Study of demand for solar systems among households, businesses and other organisations in Tonga


Tonga’s rooftop solar industry is in its nascency. While there have been efforts from government’s and donor programs to install solar systems, the number of installed solar systems which connect and share power back to the grid are few. A lack of suppliers active in the market, low availability of parts, high up-front cost, and uncertainty on pay-back periods are some of the barriers to uptake.

Global experience has shown that private sector and households are willing to invest in rooftop solar when the incentives are right and there is clear information about the potential pay-back periods. Encouraging the development of this market which has the potential to attract private investment to help Tonga meet its renewable energy targets and reduce reliance on imported diesel fuel.

To encourage more entrants into the rooftop solar market, a clear understanding of the market opportunity is needed. This includes an understanding of current electricity costs, experiences of outages, customer perception, barriers to take up and the potential market demand.

For this purpose, MDF requires the services of a consultant or firm to conduct primary research into awareness and demand for rooftop solar in Tonga. The research will involve surveys of households, businesses and other organisations. The tenderer can propose the most appropriate methodology for data collection, including in-person, phone, or mixed methods.

Objective of the study

The objective of the study is to better understand current and potential demand and barriers for adoption for rooftop solar in Tonga. This includes aspects such as the current energy costs and experiences of outages, awareness of the costs and benefits of rooftop solar installations, and financial and other barriers to uptake.

The key output of the study will be:

  • a) An assessment of current grid and back-up energy costs, time-of-usage, and outages experiences for households, the private sector and other organisations.
  • b) Analysis of current perceptions of rooftop solar for different market segments, including households and the private sector in Tonga; including:
    • • Level of awareness of rooftop solar,

    • • Knowledge of service providers,
    • • Customer willingness to pay, and
    • • Other barriers to take up.
  • c) Based on data, recommendations for organisations looking to increase uptake of rooftop solar.

It is expected that the study will commence in May 2024.
