Solar Energy Projects (SEP) has successfully commissioned a 1MVA solar energy system for Proton Bakers, the nation’s leading bread and confectionery manufacturer. This project not only secures the energy future of one of Zimbabwe’s most vital food producers but also reinforces SEP’s status as the regional leader in high-impact industrial renewable energy solutions.The success of the Proton Bakers project is rooted in SEP’s recent strategic expansion. The solar energy company recently established a dedicated branch at Number 25 Longlands Road in Marondera, positioning itself at the very heart of Mashonaland East’s industrial hub.
This local presence allowed for seamless execution and ensures that Proton Bakers, along with other regional manufacturers, has access to rapid-response technical support and long-term maintenance. SEP’s reputation as the “clean energy company of choice” is built on this foundation of in-house technical expertise and world-class technology partnerships.The scale of the installation at the Proton Bakers headquarters is immediately apparent from the air.High-angle aerial photographs reveal a sprawling industrial complex where the rooftops have been transformed into a high-tech harvesting field.
An extensive array of 1,788 dark blue, high-efficiency solar panels covers the majority of the warehouse rooftops, capturing the abundant Zimbabwean sunlight to power the precision-timed baking processes below.Direct overhead views emphasize the sheer magnitude of the installation. While the logistical yard remains a hive of activity—busy with the iconic white Proton delivery trucks—the facility now operates under a silent, green canopy. This 1 MVA plant provides the stable and consistent power source critical for high-volume production, insulating the bakery from energy fluctuations and the escalating costs of fossil-fuel-based backups.
Inside the facility, the engineering excellence continues. The power room houses a sophisticated bank of four large, white Sungrow solar inverters. These units, mounted with precision on light-coloured walls, are supported by a smaller central control unit and housed within a secure, ventilated enclosure.
The professional nature of the installation is evident in the neatly organized industrial conduits and metal trunking that manage the system’s complex wiring.
To ensure resilience during periods of low sun or grid instability, the project features a cutting-edge battery storage solution.
A clean, modern battery room contains a row of high-capacity Freedom Won “LiTE” lithium battery cabinets. These large white units, prominently branded with the “Solar Energy Projects” logo, represent the pinnacle of energy storage technology.Safety is paramount; each unit is equipped with a red “Fireball” automatic fire extinguisher. The room itself maintains a clinical, high-tech appearance with anti-static flooring and bright fluorescent lighting, emphasizing the sophisticated scale of the heavy-duty cabling and power management system.
What sets this project apart is its integration with the national power utility. Through a net-metering agreement with the Zimbabwe Electricity Transmission and Distribution Company (ZETDC), the system is optimized for national efficiency.
During peak sunlight hours, any excess power generated by the 1,788 panels is fed back into the national grid. This transforms Proton Bakers from a traditional consumer into a proactive contributor to Zimbabwe’s clean energy supply, directly supporting the government’s call for private sector participation in stabilizing the national grid.
Beyond the technical and financial benefits, the shift to solar represents a major win for environmental stewardship. The bread and confectionary maker has significantly reduced its reliance on diesel generators, lowered its carbon footprint and minimized noise pollution in Marondera.As more industrial giants look to follow this lead, the partnership between SEP and Proton Bakers stands as a benchmark for the Zimbabwean manufacturing sector. It proves that with the right expertise and technology, the sun can indeed power the future of local industry, ensuring that as Proton continues to “feed the nation,” it does so with a clear environmental conscience.
