What Soleil Power does

Soleil Power Ltd is a Ugandan manufacturer of lithium-ion and lithium iron phosphate (LiFePO4/LFP) battery systems, founded circa 2021 as a sister company to Aptech Africa under the Massawa Group umbrella. It operates a purpose-built assembly factory in Kirolo, Uganda — described as the first multi-use lithium-ion battery assembly plant between South Africa and the Sahara — with operations commencing in July 2025, three semi-automated production lines, and an annual production capacity of 40 MWh. The company's product portfolio spans custom e-mobility battery packs for electric motorcycles, scooters, vehicles, and tractors; a 5.12 kWh stationary energy storage unit rated at 6,000 cycles; a 1.28 kWh home and small-business backup battery; and scalable containerized systems supporting up to 82 kWh via parallel connection of 16 batteries.

The underlying technology is the assembly of imported Tier 1 LFP cylindrical and prismatic cells into modules and packs, integrated with a smart Battery Management System offering cell-level monitoring, protection, and control, plus IoT cloud connectivity for real-time remote monitoring, fault diagnosis, and data storage. All products are compatible with leading hybrid inverters including Victron, Sunsynk, Growatt, Deye, and SMA. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications and was recognized as East Africa's first production-scale lithium-ion battery manufacturer in Uganda's E-Mobility Outlook Report 2025.

Soleil Power generates revenue primarily through direct B2B hardware sales of battery packs and bespoke custom battery solutions, with quote-based pricing tailored to each customer's specifications. Its customer base spans residential and SMB backup power buyers, commercial and industrial energy storage customers, e-mobility operators (notably Zembo for electric motorcycle batteries and swap stations), and institutional buyers in healthcare, education, and community infrastructure across Uganda, Rwanda, and South Sudan. Distribution is executed through direct enterprise sales and via its sister company Aptech Africa, which serves as installation partner for integrated solar-plus-storage projects. The company is privately held with no disclosed VC/PE funding rounds and reports approximately 20 full-time employees.
