How Vectar Energy built ecoWise to help Nigerian solar projects sell carbon credits

Vectar Energy started in Nigeria as a maker of portable solar power stations meant to replace small petrol generators. Founder Deborah Fadeyi moved the company into climate finance after finding that hardware sales alone could not scale. The result is ecoWise, a platform that aggregates distributed solar projects into one portfolio so smaller developers can access carbon markets they could not enter individually. The company reports 35 MWp of distributed solar projects onboarded in Nigeria and a 50 MWp cohort moving through validation. It expects the first carbon credit payout to participating projects in January 2027. ecoWise uses a hybrid monitoring system that combines IoT devices with API integrations to handle different inverter types and data formats. Vectar has also entered the I-REC(E) renewable energy certificate market and plans to expand to Sierra Leone and Madagascar in 2027. For anyone tracking climate finance in Africa, this is a concrete example of how carbon credit revenue is being used to lower the cost of clean energy. The open questions are methodological: which carbon standard is used, how carbon rights are assigned, and whether the MRV evidence holds up under audit.

Interesting shift. Selling solar generators is hard when upfront costs kill demand. Moving to carbon market infrastructure means Vectar now earns from the avoided emissions data instead of the hardware margin. The 35 MWp onboarded and 50 MWp in validation are modest numbers, but if the first payout lands in January 2027 as planned, it will be a useful proof point for distributed solar aggregation in Nigeria.

The part I want to see more detail on is the monitoring. They say ecoWise uses IoT plus API integrations because distributed solar is heterogeneous. That matters, because carbon credit buyers will reject data they cannot audit. Also curious how they handle inverter failures or projects that go offline. A 50 MWp cohort is not huge, but the credibility of the MRV stack will decide whether those credits sell at $50 or m

Good example of how carbon finance can reduce the upfront cost problem instead of just talking about it. But the article does not say which Gold Standard methodology they use or how carbon rights are assigned when a developer sells through ecoWise. Those details matter for whether the credits are real and for who bears liability if monitoring fails. Worth watching how the Sierra Leone and Madagascar expansion handles

The hardware business only reached 150 customers and about 80 million naira in cumulative revenue. That is not a lot, which makes the pivot to carbon market infrastructure less like a strategy choice and more like a survival move. The real test is whether ecoWise can sign up enough independent developers to make the aggregation worthwhile. If they can, the platform might outlast the generator replacement business.
