About Osama

Senior PV & Battery Technology Consultant with 20+ years of experience in solar cell manufacturing, TOPCon process integration, and energy storage technologies. I support companies in Europe, the MENA region (Saudi Arabia, Egypt, UAE), and India with technical leadership, factory setup, process optimization, and technology evaluation.

I have worked across the full value chain of PV and battery production — from R&D and pilot lines to gigawatt‑scale manufacturing. My expertise covers TOPCon cell technology, production line design, equipment selection, yield improvement, and technical due diligence for investors and EPCs.

What I can help you with:
  • TOPCon technology development & process integration
  • PV manufacturing line setup (cell, module, or full factory)
  • Battery pack assembly process design & optimization
  • Supplier evaluation and technical due diligence
  • Production troubleshooting, yield improvement & cost reduction
  • CTO‑level technical leadership for new or growing teams
  • Feasibility studies, technology roadmaps & investment support
How I work:

I bring a structured, hands‑on, engineering‑driven approach. I focus on clear results, fast analysis, and practical solutions that can be implemented immediately. I work remotely or on‑site in Europe, Saudi Arabia, Egypt, the UAE, and India.

Why clients choose me:

  • Deep technical expertise in PV & battery manufacturing
  • Experience with international projects (Germany, EU, China, India, Saudi Arabia, Egypt, UAE)
  • Strong communication and clear documentation
  • Ability to bridge engineering, operations, and management
