Africa’s energy debate has often focused on supply. More generation. More grid expansion. More infrastructure. But in “Only the Outliers Gripe,” a book by Tonye Irims, the argument shifts from supply to structure.
The book presents a founder’s account of how a solar company evolved into a digital utility. It blends experience with analysis and places one claim at the centre: Africa’s energy challenge is not only about how power is produced, but how it is delivered and paid for.
Irims states that traditional grid expansion has not kept pace with demand. It requires public funding, long timelines and complex systems. In many cases, demand grows faster than infrastructure can respond. This creates a gap between connection and reliability.
He captures this gap in a simple line: “Access to the grid does not mean access to reliable electricity.”
This point is not theoretical. Many users remain dependent on generators despite being connected to the grid. Outages and instability continue to shape consumption patterns. The grid exists, but reliability does not follow.
The book also examines how utilities generate revenue. Irims explains that postpaid systems face persistent challenges, including billing disputes, collection issues and tariff constraints. He argues that “the classic postpaid utility model is financially fragile in many African markets.”
From this position, the book introduces prepaid solar electricity not as a temporary fix, but as a structural alternative.
Irims draws a comparison with mobile telecoms. He notes that prepaid airtime became dominant because it matched how consumers manage money. Users preferred to pay in advance, control spending and avoid unexpected bills. In his view, energy will follow a similar path.
“Electricity in Africa would follow the same path as mobile minutes,” he writes.
This comparison forms a core theme of the book. Prepaid systems align with existing behaviour. They reduce friction, simplify billing and remove disputes. As Irims explains, “You pay, then you consume, with full visibility.”
The book extends this logic to the solar market. It identifies a major barrier in the form of upfront costs. Traditional solar systems require large payments for equipment and installation. Many consumers express interest but are unable to commit.
Irims summarises the issue directly: “Demand existed — affordability structure was wrong.”
This insight led to a shift in business model. Instead of selling hardware, the company moved towards delivering energy as a service. Customers no longer buy panels or batteries. They pay for power.
The book makes clear that this change reflects customer preference. “Customers wanted power outcomes, not equipment ownership,” Irims notes. Removing ownership reduces complexity and lowers the barrier to entry.
However, the transition also introduced risk. The company took on responsibility for infrastructure, maintenance and service delivery. It required more capital and stronger operations.
Irims acknowledges that the most difficult resistance came from investors. The model did not fit established categories. It was neither a standard utility nor a simple technology business. Concerns about payback periods and asset intensity shaped investor perception.
This pressure influenced the company’s approach. It adopted a prepaid-first model to address concerns about revenue collection. It invested in digital systems to monitor performance and provide data. These steps were aimed at building confidence.
Customer scepticism was another challenge. Many users had prior experience with unreliable providers. Questions around maintenance and service slowed adoption. The response, as outlined in the book, was to focus on transparency and reliability.
Irims describes this shift as necessary. Trust had to be built into the system, not assumed.
The regulatory environment added complexity. The model operates between existing categories, creating uncertainty. Rather than confront this directly, the company adapted its deployment strategy to fit within available frameworks.
Despite these challenges, the book maintains a clear position. Decentralised, prepaid systems are better aligned with the realities of emerging markets. They match income patterns, reduce operational risk and integrate with digital finance.
Irims also challenges common assumptions. One is that energy access is mainly a generation issue. He argues instead that distribution, affordability and monetisation are the key constraints. Another is that grid expansion will solve reliability. He points out that this process is slow and resource-intensive.
Perhaps the most direct claim in the book is this: “Prepaid solar is not a bridge—it’s the destination model.”
This statement captures the broader argument. Africa is not moving towards traditional systems. It is building a different structure shaped by its own conditions.
The book concludes by pointing to future opportunities. These include the integration of energy and digital payments, the expansion into underserved but grid-connected markets, and the role of software in managing energy systems.
In each case, the focus remains consistent. Technology alone does not solve the problem. The model must reflect how people live, earn and spend.
“Only the Outliers Gripe” does not present energy as a fixed system. It presents it as a design challenge. And in doing so, it shifts the conversation from infrastructure to structure.
