Who We Are

Who We Are.

Tulima Solar is a social impact business with strong values, a clear mission and a dedicated team.

CLEAN-ENERGY SOLUTIONS

AGRICULTURAL EQUIPMENT PROVIDER TO EAST AFRICA’S RURAL ECONOMY.

Simusolar is focused on creating solar-powered products that have a direct and significant impact on productivity. We identified how to deliver clean-energy powered equipment to off-grid communities, and also how to deliver these products so that they are affordable to smallholder agribusinesses.

Simusolar provides and finances accessible, affordable, and energy-efficient equipment designed for off-grid businesses in Sub-Saharan Africa. Our systems are designed to meet the needs of rural smallholders, from equipment specifications to innovative financing terms. Our goal is to enable rural smallholder farmers and fishers to achieve their vision, affordably and sustainably.

  • We envision laborers that don’t have to migrate to cities for a better quality of life.
  • We envision rural communities that do not depend entirely on rainfall to ensure reliable food and income.
  • We envision economies that are sustainable, equitable, and inspiring to all.
