WaterEquity’s Strategic Focus on Climate Resilience

WaterEquity’s investment in SunCulture signals a strategic shift toward climate-resilient infrastructure solutions that address both water access and agricultural productivity challenges. The Water & Climate Resilience Fund brings together a diverse coalition of corporate investors including Microsoft through its $1 billion Climate Innovation Fund, Starbucks, Ecolab, Reckitt, Gap Inc., and others who recognize the critical intersection of water security and climate adaptation.

Since 2016, WaterEquity has raised more than $470 million across its investment vehicles, with projects improving water and sanitation access for over 7 million people globally. The organization’s focus on emerging and frontier markets aligns perfectly with SunCulture’s mission to serve the 600 million smallholder farming households across Africa who face productivity challenges due to limited irrigation infrastructure.

Aleem Remtula, Head of Private Equity and Infrastructure Investments at WaterEquity, emphasized the urgent need for innovative solutions: “Rural communities face the greatest challenges in accessing reliable water”, with over 80% of Africa’s rural population using sources that require collecting water outside their homes, creating a massive time burden predominantly carried by women and girls.

Revolutionary Technology Meeting Critical Need

SunCulture’s solar-powered irrigation systems address multiple challenges simultaneously, serving as both agricultural productivity tools and household water access solutions. The company’s technology enables farmers to increase crop yields by 300% while reducing water usage by 80%, representing a paradigm shift in resource efficiency for smallholder agriculture.

The versatility of SunCulture’s systems has proven crucial to their market success. While designed primarily for irrigation, over 90% of customers also use the pumps to access groundwater for drinking, cooking, and cleaning. This dual functionality addresses a critical infrastructure gap in rural Africa where most households lack on-site water access, making water collection a time-consuming daily burden.

The company’s pay-as-you-grow financing model has been instrumental in making the technology accessible to farmers who cannot afford significant upfront investments. This innovative approach allows farmers to acquire systems through manageable monthly payments, removing the primary barrier to adoption for resource-constrained smallholders.

Market Impact and Agricultural Transformation

The potential impact of solar irrigation technology extends far beyond individual farm productivity gains. According to research from the International Institute for Applied Systems Analysis, standalone solar photovoltaic irrigation systems have the potential to meet more than a third of the water needs for crops in small-scale farms across Sub-Saharan Africa. This represents a transformational opportunity for a continent where 80% of agricultural production comes from smallholder farmers.

The market dynamics are compelling: Africa’s solar irrigation market is currently valued at £24 million and is expected to grow at a 22% compound annual growth rate to reach £64 million by 2027, with full market potential estimated at £2.4 billion. This growth trajectory is driven by declining costs of solar components, increasing food demand, and strong support from governments and development organizations.

Real-world impact data demonstrates the technology’s effectiveness. In Rwanda, farmers adopting solar irrigation achieved 32% higher yields in the two main growing seasons compared to non-adopters, with many able to add a third growing season by growing crops during the dry season for the first time.

Addressing Africa’s Food Security Crisis

The urgency of SunCulture’s mission becomes clear when examining Africa’s agricultural productivity challenges. Only 6% of Africa’s arable land is currently irrigated, despite the continent having 65% of the world’s unused arable land. This irrigation gap contributes to agricultural productivity that remains 50% below the world average.

The consequences of this productivity gap are stark: Africa spends $35.8 billion annually importing food, a figure expected to reach $110 billion by 2025. According to the Food and Agriculture Organization, increased access to irrigation could lift 70 million people out of poverty in Sub-Saharan Africa by 2030.

SunCulture’s technology offers a sustainable alternative to the expensive and environmentally harmful diesel pumps that many farmers currently rely upon. African farmers spend approximately $2 billion annually on diesel-powered pumps, which strain limited resources while contributing to carbon emissions and environmental degradation.

Strategic Partnership with Research Institutions

SunCulture’s commitment to sustainable development extends beyond technology deployment to include rigorous research and best practice development. The company has established a landmark partnership with the International Water Management Institute (IWMI) to advance sustainable solar irrigation practices in Kenya.

Launched in February 2025, this collaboration combines SunCulture’s innovation in off-grid solar irrigation with IWMI’s expertise in water resource management. The partnership focuses on ensuring responsible use of surface and groundwater resources as solar irrigation adoption gains momentum across the region. Together, they have developed preliminary guidelines on efficient irrigation practices and a conceptual framework for water strategy in collaboration with key stakeholders.

Expansion Strategy and Regional Growth

With the fresh capital from WaterEquity, SunCulture plans to accelerate expansion beyond its core Kenyan market into Uganda, Ivory Coast, Ethiopia, Zambia, and Togo. This geographic diversification strategy recognizes the continent-wide nature of the agricultural productivity challenge and positions the company to capture opportunities across multiple markets with varying economic and regulatory conditions.

The company has already demonstrated its scalability by selling over 45,000 units to date, with systems serving farming operations ranging from 0.5 to 2 hectares. This scale achievement has been supported by comprehensive service infrastructure including sales and service centers, proprietary IT systems, and mobile-enabled digital platforms that provide farmers with precision agriculture capabilities.

SunCulture’s expansion strategy also includes product innovation and digital integration. The company is exploring opportunities to integrate advanced digital solutions such as remote monitoring and data analytics to enhance system efficiency and provide farmers with real-time insights into water usage and crop performance.

Corporate Social Responsibility and Gender Impact

The investment’s alignment with broader development goals extends to significant gender equity implications. WaterEquity’s focus on water access directly addresses the disproportionate burden that energy and water poverty places on women and girls in rural African communities. When households lack reliable water and energy access, women typically bear the responsibility for time-consuming water collection and fuel gathering activities.

By providing both irrigation capabilities and household water access through a single solar-powered system, SunCulture’s technology can significantly reduce the time women spend on water-related activities. Case studies indicate that farmers can save up to 17 hours per week on water collection after installing SunCulture systems, freeing up time for other productive activities or education.

Investment Ecosystem and Development Finance

The SunCulture-WaterEquity partnership represents a broader trend in development finance toward market-based solutions that can attract commercial capital while delivering significant social and environmental impact. WaterEquity’s model demonstrates how patient capital from development-focused investors can help build sustainable markets that eventually become attractive to purely commercial investors.

This approach addresses a critical gap in the financing ecosystem for agricultural technology in emerging markets. Traditional venture capital often considers agricultural technology investments too risky or slow-growing, while pure development aid may not create sustainable market-based solutions. Impact investors like WaterEquity bridge this gap by accepting lower short-term returns in exchange for measurable social and environmental outcomes.

The success of this model could encourage other impact investors to support agricultural technology companies across Africa and other emerging markets. The combination of strong commercial performance – SunCulture has demonstrated both rapid growth and strong unit economics – with clear development impact creates a compelling investment thesis that could be replicated across other technologies and markets.

Future Market Development and Scaling Challenges

Despite the compelling market opportunity and demonstrated technology effectiveness, several challenges remain for scaling solar irrigation across Africa. Research has identified structural barriers including uncovered risks, lack of incentives, and limited local capacity as key factors limiting adoption of solar-powered irrigation.

These challenges include higher costs in Sub-Saharan Africa due to limited market development and geographical constraints, lack of regulation, and low investment in building local institutions and value chains. Addressing these systemic issues requires coordinated efforts between private companies like SunCulture, impact investors like WaterEquity, and government and development partners.

SunCulture’s approach of building comprehensive local infrastructure – including service centers, training programs, and financing partnerships – demonstrates one model for addressing these challenges. The company’s success in achieving market leadership while maintaining strong unit economics suggests that well-executed market development strategies can overcome traditional barriers.

Looking ahead, the continued growth of the solar irrigation market will depend on sustained investment in technology development, market education, supportive policies, and innovative financing mechanisms. The WaterEquity investment provides SunCulture with resources to continue building these market foundations while expanding geographic reach and developing new products and services.

As CEO Samir Ibrahim noted, “WaterEquity understands that water investments don’t fall into a single box – scaling water infrastructure can deliver both incredible impact and strong commercial returns”. This recognition of the dual value creation potential – commercial and social – represents the foundation for sustainable market development that can ultimately transform agricultural productivity across Africa.
