Five Solomon Islands provinces are set to have almost all their power needs generated by solar energy.
The Solar Power Development Project aims to construct solar plants in Makira, Temotu, Malaita, Western and Central.
The Asian Development Bank will provide some aid toward the $US15 million dollar project but the bulk of the money will come from both the Strategic Climate Fund and the Solomons' government.
Most of the electricity generated in Solomon Islands is from diesel and the ADB's Anthony Maxwell said this project would help reduce the cost of generation, and reduce greenhouse gas emissions which lead to global warming.
