Power on Credit: How Pay-as-You-Go Solar Lit Up Off-Grid Kenya

For millions of families living beyond the reach of the national grid, keeping a light on after dark once meant burning kerosene, an option that was costly, smoky and often dangerous inside a small home.

In Kenya, a wave of technology has quietly changed that picture, turning electricity into something that can be bought a little at a time, much in the same way that people top up airtime on a mobile phone.

Electricity by the day

The idea behind pay as you go solar is simple, as a household pays a small deposit for a compact solar home system that usually includes a panel, a battery, a few lights and a socket for charging phones.

After that, the family buys small credits to keep the system running, often for less than the daily cost of kerosene, and once enough payments have been made the equipment becomes theirs to own outright.

The M-KOPA model

One of the pioneers of this approach was M-KOPA Solar, a company based in Nairobi and founded in 2011, which grew into one of the global leaders in pay as you go energy for customers living off the grid.

By 2019 it had reached close to seven hundred and fifty thousand households across Kenya and Uganda, and reported repayment rates of around ninety five per cent even among families on very modest daily incomes.

Built on mobile money

None of this would have been possible without the country's remarkable mobile money system, which allows even the smallest of payments to be sent instantly and cheaply from a basic mobile phone.

In that sense the clean energy revolution in rural Kenya is tightly bound to the nation's fintech backbone, with each solar payment flowing through the same digital rails that Kenyans use every day.

A big share of the grid gap

The scale of the shift is considerable, and according to Kenya's National Energy Compact for the years 2025 to 2030, standalone solar systems now account for around one point two million households, close to twelve per cent of the country's electricity access.

That sits alongside mini grid systems serving roughly a hundred and ten thousand homes and the national utility supplying about eight and a half million, showing how solar has filled a gap that the wider grid has yet to close.

More than just light

For the households involved, the benefits reach well beyond a brighter room, since reliable power means children can study in the evening, phones stay charged and families can listen to the radio or watch television.

It also removes the fumes and fire risk that came with kerosene lamps, while opening the door to small appliances that can support little businesses and make daily chores a good deal easier to manage.

A model for the continent

Kenya has in many ways served as a testing ground for this model, and the lessons learned there have since spread to other parts of Africa where large numbers of people still live without a reliable connection.

By selling power in small and affordable pieces, the technology has shown how innovation tuned to local conditions can reach places that traditional infrastructure has long struggled to serve.
