The company, which provides renewable energy solutions to commercial and industrial clients across sub-Saharan Africa, plans to channel the funds into expanding its existing operations.

A significant share of the investment will be directed toward Nigeria, where unreliable grid electricity and heavy reliance on diesel generators continue to shape the energy landscape.

The financing will support the rollout of new solar projects for business customers while also strengthening services for current clients.

This includes upgrading and replacing energy assets to maintain operational efficiency and reliability.

“Partnering with BII marks a significant milestone for the Starsight Energy Africa Group. This funding strengthens our ability to scale more rapidly in Nigeria and Ghana, delivering reliable, clean energy solutions that support economic growth and improve energy resilience for our clients,” said Paul van Zijl, Group CEO at Starsight.

The deal reflects growing investor confidence in distributed renewable energy solutions for businesses across the region.

Companies like Starsight are increasingly positioning solar power as a cost-effective alternative to fossil fuel-based generation, particularly in markets where grid supply remains inconsistent.

BII said its investment aligns with its broader mandate to support sustainable development and private sector growth in emerging markets.

“Nigeria’s businesses need dependable and affordable power to grow. We identified Starsight’s strong track record, combined with its clean energy model, as a strong fit with BII’s mandate,” said Benson Adenuga, BII’s regional director for West Africa and head of its Nigeria office.

“Starsight’s commercial and industrial solar solutions directly address this challenge by reducing dependence on refined petroleum products and improving reliability.”

The investment comes at a time when demand for alternative energy sources is rising across West Africa.

In Nigeria, businesses often rely on self-generated power due to grid instability, creating an opportunity for solar providers to offer more reliable and environmentally sustainable solutions.
