Millions of Africans still live without access to reliable electricity. While governments and large utilities work to expand national grids, many communities and institutions remain underserved due to cost, infrastructure, and terrain challenges. This is where flexible, engineering-driven energy consulting companies like Holistic Energy Solutions are stepping in – not with grand promises, but with practical, scalable energy solutions.
A Consulting & Engineering Approach
Founded and led by Tshepo Marengwa, Holistic Energy Solutions operates as a consulting and engineering firm focused on helping clients identify, plan, and implement sustainable energy solutions. The company works with developers, commercial and industrial (C&I) clients, and institutions looking for independent and professional energy advice – not sales pitches.
Rather than simply selling equipment, Holistic Energy Solutions provides:
- Site assessments and feasibility studies
- System design and engineering
- Project management support
- Technical advisory and reporting
Their strength lies in offering neutral, data-driven guidance to help clients choose the right technologies – solar, hybrid, or otherwise – based on need, budget, and long-term impact.
Supporting Off-Grid and On-Grid Solutions
While the company does not install systems directly, it supports clients in designing and implementing off-grid, grid-tied, and backup power systems. This includes working with architects and developers during planning stages to ensure buildings and facilities are energy-smart from the ground up.
They also help clients navigate energy storage, hybrid integration, and procurement choices to avoid common pitfalls in solar and inverter system setups.
Realistic, Scalable Impact
Holistic Energy Solutions is not claiming to power millions overnight. Instead, they’re building a solid reputation by helping businesses, schools, and residential developers make informed energy choices. In a space crowded by vendors and installers, their consulting-first model brings clarity and confidence to decision-making – especially for clients who want long-term value and not just short-term fixes.
Collaborating for Practical Change
The company is also actively forming partnerships with professionals in the built environment – architects, QSs, and fellow engineers – to align energy planning with project timelines. This collaborative and early-stage involvement is one of the key ways they’re contributing to more sustainable energy use, one project at a time.
Energy access in Africa is a challenge that needs grounded, professional solutions. Through a consulting-led model, Holistic Energy Solutions, under the leadership of Tshepo Marengwa, is helping bridge the gap with practical tools, expert insights, and a collaborative mindset. The company isn’t just joining the energy conversation – it’s helping shape it with integrity and expertise.
