Who Am I?

I am the Cofounder & Director of Solar Mango, a division of EAI.

I am a renewable energy professional having a decade’s experience as Consultant, with specialisation in solar PV and biomass-energy sectors, bringing together a unique intersection of top management perspectives, India market knowledge and extensive expert contacts.

Why is My Team’s Consulting Unique?

We are about making a big business difference.

We define our job not as a consulting firm but as a team that will go out of way to ensure our clients get the analytical and practical assistance to win in the market.

As Consultants, my team and I operate with the following business perspectives

  • Size is Not the Same as Profits - A large and fast growing industry does not necessarily imply large profits for market entrants
  • Eventually, Exceptional Business Success Comes Down to Solving a Real Pain Point really well at a cost lower than what the customer is willing to pay for the pain point resolution.
  • Differentiation is the Key for any Business or Entrepreneur. If you cannot differentiate, you might as well work for someone who can!

We rarely focus on giving reports alone, as Consultants. Instead, we rely on closely working with the client’s management and operational personnel, and embed ourselves as part of their teams to deliver practical results.

What Do I Bring to the Table?

  • In-depth understanding of operations, business models, economics for rooftop and grid connected solar power plants
  • Foot on the ground - I understand what works and what's just moonshine, in solar, biomass energy, and to a certain extent, in wind energy.
  • Expertise to establish clear economic and operational feasibility for solar power plants and biomass-based heating
  • Exceptional contacts in the Indian solar energy sector - across the entire stakeholder spectrum - from manufacturers to EPCs and other solution providers to government to technology experts to financial institutions.

Summary of Skills

    My BioMetric team is perhaps the only expert consultant team in India that has worked on the market facing pain points for the use of biomass for heat and power. My and my team’s expertise in bio-energy spans the following domains:
    • Biomass-based heating and cooling – technical and economic feasibility
    • Optimisation for supply chain and use in boilers – Comprehensive optimization strategies across the entire supply chain, from feedstock selection, to logistics to processing.
    • Biomass gasification – technical and economic feasibility, and integration of gasification with incumbent boiler or hot air generator systems
