This month, University of the South Pacific engineering students, solar technicians and managers installed an off-grid solar system to power a school.
Renewable energy is now running through four school buildings, 10 teachers' homes and three hostels of Ratu Naivalu Memorial School, on Fiji's Waya Island.
This was roughly the first 70th project undertaken by the Its Time Foundation, underpinned by Australian foreign aid, to bring electricity to remote parts of the Pacific nation.
But it was the first carried out by an all-female crew, thought to be a first for the region.
"One of the coolest things that we've done in our 15 years," Its Time founder Rob Edwards said.
"And they absolutely hit it out of the ballpark."
One of the students involved, Sereana Cabemaiwai, said the project was both fulfilling and overwhelming.
"Knowing what I did, what I contributed to, will contribute to kids' lives in Ratu Naivalu, it's emotional for me," she said.
"Having the experience we just had, I'm really more inclined to work in renewable energy now, more than ever."
Fiona Dace-Lynn, a director at the Canberra Institute of Technology, said Fiji faced similar issues to luring women into construction and trades as Australia.
She reported high on-site satisfaction from the women engaged in the Waya Island project.
"One of the things they said was they felt comfortable to be able to make mistakes, to test things, and ask questions," she said.
"Sometimes they don't get the opportunity to do (that) when they're probably in most cases the only female on the job."
The project has been feted at a conference in Suva this week, where dozens of renewable energy enthusiasts and engineers are gathering.
Funding bodies, including donor countries like Australia and New Zealand, as well as the UN and Asian Development Bank, are eager to sponsor solar projects in underdeveloped pockets of the region.
Ms Dace-Lynn said upskilling women was likely to produce another benefit: the retention of a skilled workforce.
Pacific nations must contend with the pull - particularly for young men - to the region's richer labour markets, including through guest worker schemes in Australia and New Zealand.
"Because women have a caring obligation as well, it's less likely that women will leave," Ms Dace-Lynn said.
"It's absolutely perfect to engage this workforce.
"This is where their family are, where their parents are, and quite often they have children as well."
Mr Edwards is hopeful that funding will keep coming after "good conversations with some multilaterals and some others" in Suva.
"We're hopeful we can come out of this week with some more scaling to come," he said.
