The solar lantern is a revolutionary piece of technology.
Operating with a small in-built solar panel, connected to a battery and using an LED light bulb, it can transform how rural communities see the world.
Its use in places without access to mains electricity has taken off in the past 15 years, alongside the wider growth in solar power around the world.
An estimated 600 million people in sub-Saharan Africa still live without reliable access to electricity, according to the World Bank. The introduction of solar power – coupled with energy-efficient lighting – is key in tackling this problem.
Many villages not served by national grids are forced to use kerosene lamps and candles, or burn straw in the evening, which is costly and dangerous to human health. London-based think-tank ODI Global estimates that low-income households in Africa spend US$6.5 billion a year on such inefficient lighting options.
Solar power changes the equation, allowing streets to be lit, children to study at night, and a sense of security to exist. Greater electricity access enables farmers to work an extended day and use solar-powered irrigation and cooling systems to grow and process their crops.
African leaders seek investments in ailing grid infrastructure to achieve energy goals
“Reliable and affordable energy creates economic transformation,” said Eva Roig, a spokesperson for GOGLA, an Amsterdam-based trade body for the off-grid solar energy industry. The organisation estimates that US$9 billion in additional income has already been created by businesses as a result of switching to solar in place of fossil fuel alternatives.
“In off-grid locations, lack of energy restrains farmers from higher productivity and, with a growing young population, offers few employment opportunities or possibilities to create new businesses,” she added.
The challenge for off-grid solar power is to reach the hundreds of millions of people in need and create a stable market for its continuance.
Electric power key to tackling poverty
UK charity SolarAid was founded in 2006 with the aim of creating a world “where everyone has access to clean, renewable energy” and eradicating the use of kerosene lamps in Africa.
A couple of years later it set up SunnyMoney, a social enterprise which uses a community distribution model to raise awareness and increase demand for solar power. Local teachers explain how the technology works and independent agents sell the products. SunnyMoney supports them with logistics, training and engagement along the way.
“We believe that access to electricity is fundamental in the fight against poverty. Access to solar lighting and power means that families are saving money, extending productive hours, increasing access to study hours and also increasing safety,” explained John Keane, CEO at SolarAid, based in Zambia.
The charity has reportedly helped 12 million people through the social enterprise, with projects in Senegal, Uganda, Tanzania, Kenya, Zambia and Malawi.
While models such as SunnyMoney can stoke the solar market, larger businesses need to step in and supply the kit itself. D.light is one of the solar companies that has done more than most to bring affordable solar power to some of the remotest villages in Africa.
Finance for renewable energy in sub-Saharan Africa is defying the odds
The US company is deeply embedded across the continent, with a vision to make solar products accessible to low-income families. The business had one of its most successful years in 2024, and says it reached 24 million people with solar systems last year alone.
But it hasn’t always been plain sailing. “I don’t think we realised how difficult it would be to commercialise and scale off-grid solar products,” d.light’s founder and CEO, Nedjip Tozun, commented in an interview last year.
While its products now power around 32 million homes, building that capacity took time, patience and good fortune. Tozun explained that during the early years in the mid 2000s the difficulties lay in building a high-quality product which could be distributed to remote areas and with financing to enable people to pay for it. The company was forced to create those capabilities in-house in order to scale and overcome external barriers.
Funding energy efficiency to expand use
Improving energy efficiency is one such challenge the off-grid industry has sought to solve. Solar devices need to hold the sun’s energy long enough to be used for a wide range of purposes. This is where LED lighting comes in.
“Over the past 10 years, the growing availability of increasingly energy-efficient appliances, such as LED lighting is transforming what’s possible,” said Keane. “It’s the foundation for designing inclusive solutions that deliver long-term impact.”
The main benefits, he explained, is that LED lighting drastically reduces the amount of electricity needed to light homes, enabling households on lower incomes to meet their essential needs with small solar systems.
As off-grid solar kits are small by design, using the power with efficient lighting or low-voltage appliances, such as refrigerators, means the energy goes further and is matched to the user’s needs.
Pairing solar with technologies to support economic activity, so-called “productive use”, is a growing area within the industry. Solar can be applied in a range of commercial settings, and on any number of appliances, from sewing machines to water pumps, or from seed pressers to ceiling fans. But to do so effectively those appliances need to be energy-efficient and upgrading is expensive.
New financing initiatives such as PUFF – the Productive Use Financing Facility – are playing a role by offering subsidies to suppliers to help bring down the costs for farmers and businesses. After a successful pilot, the scheme was recently extended with an additional US$6.1 million to support access to 10,000 “high-impact” appliances, according to CLASP, a non-profit which started the initiative.
“Efficient appliances and equipment turn energy into opportunity and should be considered essential energy infrastructure, alongside renewables,” commented Emmanuel Aziebor, a senior director at CLASP, in a media statement.
Financial barriers to adoption
Overall, the coming together of small solar technology, LED lighting and socially minded businesses has grown the market significantly over the past decade.
In Kenya, off-grid solar now accounts for an estimated 75% of rural electricity access. The country has a target to reach universal access by 2030 and solar plays a big part in the government’s plans.
But the same barriers to scaling the market remain. Despite the success of using mobile technology and pay-as-you-go models to spread out costs for the consumer, affordable solar products are still out of reach for many. Research from ESMAP, an energy programme run by the World Bank, found that only 22% of households that lack electricity globally could afford the monthly payment to access a basic solar lantern and home system able to provide power for at least four hours a day.
“Governments should fully integrate off-grid solar into their national energy plans and programmes,” said Roig of GOGLA, adding that incentives such as tax breaks, subsidies and public-private partnerships are needed to reach the poorest households.
Making solar affordable for all
One way to bring down costs for consumers is to de-risk investments for solar power producers. The Beyond Grid for Zambia pilot project sought to do exactly that by providing financing to companies on a per-connection basis.
The project, which ran from 2016 to 2022, also worked with the Zambian government to smooth market access, such as providing a VAT exemption for LED lights. The successful results – with over 194,000 households fitted with off-grid solar – have led to ambitious plans to scale the project across the whole African continent.
The remoteness of many villages makes repairing and maintaining solar kits another challenge. Collecting, servicing and replacing these products can be expensive for companies. Research from SolarAid suggests that while manufacturers agree that repair work needs to improve, it remains an ambition for many.
Among the possible solutions include extending warranty times, providing technical training in-country, and greater guidance on how to conduct repairs at the community level. SunnyMoney already provides technicians with its own mobile repair app, which could be expanded and used as a template for manufacturers.
Despite the challenges, the work to reach tens of millions of remote households is being reinforced and stepped up. SolarAid is midway through a pilot project to connect TA Kasakula, a village in rural Malawi where almost all residents live in extreme poverty. The project is trialling a new financing model which eliminates upfront costs, with customers only paying for the electricity they use.
The stories coming back to the social enterprise are of revelation and changed lives. “When we switched on the lights, some children were dancing, jumping,” reported Goodwill Kongalwa. “Then everyone rushed to where there were books because they saw they had a chance to study at home.”

How off-grid solar is beating the odds to transform lives in rural Africa
Vishal Prasad is director of Pacific Islands Students Fighting Climate Change.
When the International Court of Justice (ICJ) delivered its advisory opinion on climate change last year, it marked a turning point not just for the Pacific, but for international climate law.
The court was unambiguous: states have legal obligations to protect the environment from greenhouse gas emissions, and they face accountability when they fail. For those of us who carried this campaign from a classroom in Vanuatu to Europe and New York, it was a moment of profound validation.

But we have always said that the advisory opinion was a tool, not an endpoint. The ICJ affirmed what many in the Pacific have been saying for some time. Now we have a legal blueprint, we must carry this momentum from the courtrooms to the negotiating rooms.
Potential to shape climate politics
The advisory opinion has already begun to reshape the climate landscape. At COP30 in Belém, we saw countries that had supported the campaign citing the opinion in their interventions, while those blocking progress were clearly concerned of its implications. Its potential to shape climate politics and policy is significant.
This year we have arrived at the mid-year climate negotiations in Bonn not only with the advisory opinion, but with a UN General Assembly resolution endorsing it. Despite a fierce campaign from the usual suspects, just eight countries, including the USA, Saudi Arabia, Russia and Iran voted against. That is a victory for multilateralism at a moment when multilateralism is under strain.

But we know that advisory opinions alone are not enough. Legal clarity will not automatically translate into reduced emissions, increased finance flows or stronger national climate plans. That translation requires political will in the negotiating rooms, both here in Bonn and all the way through Fiji and finally in Antalya this November.
What the Pacific needs from this negotiating year
The Pacific put significant political capital into the joint Australia-Pacific bid for COP31. It is fair to say that the compromise of Australia holding the role of president of negotiations while the COP is held and presided over by Türkiye is not what we imagined.
But we in the Pacific are used to looking for silver linings. Both Australia and Türkiye have acknowledged the important role the Pacific will have at COP31, through the appointment of Pacific champions and the hosting of a Pacific Pre-COP in Fiji with a leaders event in Tuvalu. These are genuine opportunities to bring the world to our shores and ensure that Pacific issues are front and centre going into the final negotiations.
But we are not naive. Envoy positions and meeting locations are just the architecture of goodwill. We need to see that goodwill converted into concrete negotiating outcomes and finance.

The Pacific helped put Australia’s climate minister Chris Bowen in this important position, so we expect to see Australia advocate not only for us, but to turn a mirror towards itself as one of the world’s biggest fossil fuel exporters.
At Bonn, and then in Antalya, we need ambition on mitigation that reflects the ICJ’s clarity on state obligations and the science. That means action on fossil fuels.
We need climate finance that is new, additional and accessible to the countries that need it most. In the Pacific we have already demonstrated what that looks like.
The Pacific Resilience Facility is the first climate finance facility designed, governed and managed by Pacific people, built specifically to reach the grassroots and community initiatives that larger funds routinely bypass. We need the international community to meet that ambition with contributions that reflect climate justice, starting with pledges to meet the $500-million capitalisation goal.
And we need the oceans – which are the lifeblood of the Pacific and a critical part of the global climate system – treated as a central element of the negotiations rather than a thematic aside.
Energy crisis driven by imported fossil fuels
The days of speaking about climate and fossil fuels purely as a moral issue are long gone. Pacific ministers recently adopted the Tassiriki Call for a Fossil Fuel Free Pacific, in the context of a deepening energy crisis that has triggered states of emergency in several Pacific nations. Our dependence on imported fossil fuels is both a climate and an economic vulnerability.
Conflict in the Middle East is pushing our region into an energy crisis. We are dependent on imported fossil fuels for 80% of our energy needs. My home country of Fiji could see an increased fuel bill of nearly three times our annual healthcare budget.
Comment: COP31 must persuade countries to make fossil fuel transition plans
We need the technical and financial support to transition to 100% renewable energy. Not only because it is what the world owes us for decades of carbon pollution that continue to render parts of our home uninhabitable, damaging ecosystems and culture. But because we must be part of that transition. Fossil fuels have proven to be the greatest source of damage to our climate, and with their volatility, to our sovereignty as well.
What next?
The demands have not changed. Greater action on mitigation, adaptation, finance, loss and damage: these remain the substance of what the Pacific requires from the international community. What has changed is the legal foundation beneath them.
The ICJ has affirmed that these are not requests. They are obligations. The task this year is to make the negotiations reflect that.

A 20-year record reveals an estuary tipping toward a saltier, more acidic state. These conditions threaten its hammerhead shark nursery and the aquifer that supplies Miami’s drinking water.
In the shadow of Miami’s skyline, in water churned daily by boats and jet skis, juvenile great hammerhead sharks—a critically endangered species—spend the first two years of their lives. A few miles from downtown, researchers recently pulled a 12-foot critically endangered sawfish from the same shallows. The species has been dying off in alarming numbers across South Florida’s waters since 2024, in an event scientists suspect was set in motion by record ocean heat.
