About

Progress stops where power ends. For more than 600 million people across Africa, unreliable electricity is not a temporary inconvenience. It is the main barrier to healthcare delivery, food production, connectivity, education, and local economic growth. I’m Guillaume Burstert, Founder & CEO of Sunwise. An industrial engineer by background, not a career startup founder. Before Sunwise, I spent 15 years managing complex EPC and industrial projects in energy, automotive, and heavy industry, delivering USD 38M+ portfolios across China and international supply chains. That experience led to a clear conclusion: Energy technology already exists. What fails is deployment. Grid expansion is slow. Traditional mini-grids are site-specific, complex, and difficult to finance. Logistics, not innovation, is the real bottleneck to energy access. Sunwise was built to solve that. We engineered the SUS-10 “Minigrid-in-a-Box”, a containerised, pre-commissioned solar power system designed for diesel replacement and energy resilience in off-grid and weak-grid environments. Each unit integrates: ☀️Expandable solar PV 🔋Battery Energy Storage Systems (BESS) 📡Remote monitoring and control via EMS / 5G The result: • Deployment in under 60 minutes • Up to 5x lower operating costs • 96% CO₂ reduction from day one • No heavy civil works • Designed for bankability and repeatable scale This is energy infrastructure delivered as a product. Sunwise solutions are deployed where reliability matters more than theory: • NGOs and rural clinics requiring 24/7 power • Telecom operators replacing diesel at remote towers • Farmers and agritech projects powering irrigation and cold storage • Construction, mining, and remote industrial sites • Communities and local authorities expanding energy access beyond the grid We work with energy providers, mini-grid developers, NGOs, EPCs, and infrastructure investors to turn approved projects into operational sites, faster. As part of Mission 300, our objective is to • deploy 600 Sunwise units, • deliver reliable energy to 2.5 million people • contribute to the goal of electrifying 300 million lives across Africa. Not through pilots. Through deployable, fundable infrastructure. If you are dealing with • diesel dependence, • slow electrification, • fragile power in remote environments, 📩 We should talk. Because when we bring light, we unlock everything. Sunwise – Energy Beyond Borders.

Sunwise

Chief Executive Officer

Sep 2024Present · 1 yr 8 mos · Shanghai, China · Hybrid

  • I founded Sunwise to solve the main failure of energy access in Africa: deployment.
  • I lead the design, deployment, and scaling of containerised solar and battery energy systems for off-grid and weak-grid environments, with a focus on diesel replacement, reliability, and bankable execution.
  • My role spans product engineering, logistics, partnerships, and deployment strategy across underserved regions.
  • Key responsibilities and outcomes:
  • Leading the deployment of Decentralised Renewable Energy (DRE) systems for rural communities, NGOs, telecom infrastructure, agriculture, and remote industrial sites across Sub-Saharan Africa.
  • Engineered the SUS-10 “Minigrid-in-a-Box”, a containerised, pre-commissioned solar + Battery Energy Storage System (BESS) designed for rapid installation, diesel displacement, and energy resilience in off-grid and weak-grid markets.
  • Built a plug-and-play infrastructure model enabling deployment in under 60 minutes, without heavy civil works, while reducing operating costs by up to 5x and cutting CO₂ emissions by 96% from day one.
  • Structured solutions around Productive Use of Energy (PUE) applications, powering irrigation, cold storage, milling, clinics, and small businesses to ensure economic impact and long-term project viability.
  • Secured and managed strategic partnerships with EPC contractors, technology providers, NGOs, local federations, and infrastructure stakeholders to accelerate last-mile electrification.
  • Working with investors and development actors to align projects with bankability requirements, blended-finance models, and repeatable deployment frameworks.
  • Sunwise is built as energy infrastructure, not pilot technology.
  • The objective is simple: turn approved projects into operational sites faster.
