The most important piece of energy infrastructure in a village without a grid is not a solar panel. It is a charged battery you can carry home. Jaza Energy has built its entire business on that simple, portable fact, and its customers have carried those batteries back and forth more than three million times [careers-page.com].
Founded in 2015, the Halifax-based company operates a last-mile solar utility in off-grid communities across Tanzania and Nigeria. Its model is a physical network: solar-powered energy hubs, built locally in Dar es Salaam, where portable lithium-ion battery packs are charged [Entrevestor.com]. Households rent these "Jaza Packs" for daily or weekly fees, using them to power lights, phones, and small appliances, before returning the depleted units for a fresh swap [Jaza Energy, retrieved 2024]. It is a utility service stripped down to its most mobile component, designed to undercut the ongoing cost of kerosene and small solar lanterns.
The Wedge is a Woman with a Shop
Jaza's primary innovation is not technical. It is distribution. Each hub is operated not by a corporate employee, but by a local micro-retailer, known internally as a "Jaza Star" [Jaza Energy, retrieved 2024]. These are overwhelmingly women entrepreneurs who run the hubs as their own businesses, handling customer relationships, swaps, and payments. The company provides the hardware, training, and backend software; the Star provides the trust and daily presence.
This model turns a capital-intensive infrastructure problem into a franchisable, income-generating opportunity. It also provides a scalable answer to the last-mile service and collection challenges that have sunk many well-intentioned off-grid projects. Each hub, according to project descriptions, can serve up to 300 households [EEP Africa]. The energy is clean, but the unit of commerce is familiar: a battery rental, paid for with the cash at hand.
A Decade of Quiet Traction
Jaza has been at this for nearly a decade, a longevity that separates it from venture-backed climate tech sprints. Its funding history is fragmented across impact investors and development funds, with total capital raised estimated between $5 million and $7.8 million [CB Insights] [PitchBook]. The backers are a who's who of patient, impact-focused capital.

Traction is measured in swaps and people reached. The company reports over 3 million battery swaps since 2022 and says it provides approximately 225,000 people with access to clean energy [careers-page.com]. A more ambitious claim of powering over 1 million people is also made, though it lacks third-party verification [Jaza Energy, retrieved 2024]. The core activity, however, is unmistakable: a steady, repetitive transaction of energy exchange, happening thousands of times a day across hundreds of hubs.
The Unit Economics of Displacement
For a climate editor, the interesting math is not in revenue multiples, but in fuel displacement. The company states that every hour of light provided by a Jaza pack displaces kerosene or diesel [ecohubmap.com]. Doing a back-of-the-envelope calculation: if the average rented battery provides four hours of light per day to a household, and the company has facilitated 3 million swaps, that represents roughly 12 million hours of kerosene-free light. Convert that to avoided CO2 and particulate emissions, and the climate and health impact starts to crystallize into a tangible, if estimated, figure.
The business, however, must compete on price and convenience, not just virtue. Its primary incumbent is not another solar company, but the existing energy economy of the off-grid household: bottled gas, kerosene, disposable batteries, and cheap, polluting generators. To win, Jaza's service must be more reliable and ultimately cheaper over time than the drip-feed cost of these alternatives. Its bet is that a centralized, high-quality solar charging station, paired with durable, swappable batteries, can achieve that.
Where the Grid Isn't Coming
The market tailwind is a stubborn fact: grid extension is slow and prohibitively expensive for remote, low-density populations. In Sub-Saharan Africa, over 500 million people still lack reliable electricity access. Companies like Zola Electric, M-KOPA, and Bboxx have built substantial businesses selling or financing solar home systems (SHS) to this market. Jaza's swap model offers a different wedge. It requires no large upfront payment or credit check from the customer, just a small rental fee. It also centralizes the most expensive hardware,the solar generation and charge controllers,at the hub, rather than putting a panel on every roof.
- The swap advantage. Customers avoid the high initial cost of a full SHS and the long-term maintenance burden of a panel and battery on their property.
- The hub advantage. Jaza manages the health and performance of the core generation and storage assets, which should, in theory, lead to longer system lifespans and better utilization.
- The retail advantage. The Jaza Star network provides hyper-local customer service and cash collection, a layer traditional utilities struggle to replicate.
The model is asset-heavy for Jaza, however. Building and deploying hundreds of solar hubs and thousands of battery packs requires significant capital. The company's relatively modest funding total to date suggests it has been capital-efficient, likely relying on grants and results-based financing to subsidize early hub deployment [EEP Africa]. To scale meaningfully beyond its current regions, a larger equity round focused on manufacturing and hub rollout seems a logical next step.
The Next Twelve Months
The path forward involves more of the same, just more of it. The company will need to prove it can replicate its hub-and-star model in new territories without sacrificing unit economics or service quality. Key things to watch will be any announcement of a Series B round to fund expansion, partnerships with larger distributors or telecoms to accelerate hub placement, and deeper data on customer retention and battery cycle life.
The calculation for Jaza is not about beating flashier competitors in the solar home system space. It is about proving that a distributed, battery-swap network can be a more capital-efficient and customer-friendly way to deliver electrons than putting a panel on every roof. If the unit economics hold, and those three million swaps turn into thirty million, they will have built a utility where one literally didn't exist before. The incumbent to beat isn't another startup; it's the jerrycan of kerosene at the roadside stall.
