Sunculture Kenya Ltd

East AfricaInfrastructure

SunCulture is a solar irrigation company, serving smallholder farmers growing high value fruit and vegetables in Kenya with products for spray/mist irrigation, drip irrigation and solar pumping.

Our investment

Description of the investment.

Our investment in SunCulture is the first transaction under our Memorandum of Understanding with the Shell Foundation and our first direct investment in the carbon credits market. The facility will allow SunCulture to test how carbon credit revenue can be used to lower the upfront cost of solar water pumps, improving the affordability of solar irrigation systems, mitigating greenhouse gas emissions, and improving the adaptation and resilience of smallholder farmers.

Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.


  • Enable avoided/reduced emissions by selling greenfield pumps to farmers who previously lacked access to a water pump, and by displacing fuel pumps of farmers who currently use them (SDG 13).

  • Aid the adaptation and resilience of smallholder farmers against adverse climate risks. The investment will do this by providing access to a water-efficient, affordable solar-powered irrigation system instead of depending on less-efficient fuel pumps and rain or communal surface water bodies, which are vulnerable to drought (SDG 13.1).



Our capital will help in pre-financing the carbon credits generated from SunCulture’s solar water-pumps. These credits will help the company in discounting the price of pumps. We estimate that overcoming this pricing hurdle would enable an even larger number of smallholder farmers to purchase the product and access the associated climate change resilience benefits.


Stakeholder Geography Characteristics


As per a 60 Decibels survey conducted in Dec 2022: a) 32 per cent of the farmers live in relative poverty, on less than $3.20 per day [2011 PPP]; b) In the last 12 months, 97 per cent of the farmers cultivated less than five hectares, and 85 per cent of the farmers cultivated less than two hectares.

How much?

Scale Depth/Duration

Our investment will enable SunCulture to sell 9,000 solar water-pumps with each pump expected to abate 2.9 tonnes of CO2 emissions per year for seven years.


  • 90 per cent of the farmers improved their way of farming, explaining that they were able to improve their farm irrigation, adopt better farming practices, and grow new crops.

  • 90 per cent of the farmers increased their farm’s production. Of those, 83 per cent reported improved productivity and 17 per cent reported increasing the amount of land they cultivate.

  • 87 per cent of the farmers reported increases in the money they earn from farming.

  • 89 per cent of the farmers reported improvements in their overall quality of life because of SunCulture.



Financial additionality: There is limited financing available for innovative financing instruments involving carbon credits. Grant capital isn’t available in adequate quantity to help scale the project.
