Rainmaker Solar-Powered Water Pump



Country:
Kenya
Why to choose this solution?
The Rainmaker is a portable solar-powered water-pumping system designed for small-scale farming and household use. It can lift water to a maximum height of 100 m, with a capacity of seven cubic meters per day, ensuring a steady supply of water for farming and household needs. It can provide sufficient water for up to 1.5 acres of irrigation. It can also be used for livestock and domestic household needs. The Rainmaker pumps a lot of water and does not use any fuel other than sunlight.
Savings per day or production:
Initially, users of electric water pumps used to irrigate crops had to pay an average of KSh 4,500- 5,000 (USD 45-50) in monthly electricity bills. Running the Rainmaker system now costs KSh 2,500-2,800 (USD 25-28) per month, saving about KSh 2,200 (USD 22) per month, i.e., KSh 73 (USD 0.73) per day.
Cost in money and in own time to construct:
Costs KSh 50,000 (USD 500). A survey fee of KSh 4,500 (USD 45) is charged when a field agent visits a site, of which KSh 2,000 (USD 20) is a sales analysis fee. Installation usually takes one day, and the technician conducts proper on-site training for end-users.
Lifetime:
Not specified.
Maintenance needed:
Post-installation issues such as permanently mounting solar modules of the Rainmaker pump on the roof.
Resources needed in use:
Water, and solar power.
Problems and limits:
Entry of cheaper fake and counterfeit products into the Kenyan market affects customer trust and confidence that have been built in their products so far and could have a negative impact on sales.

Installation of Rainmaker solar-powered water pumps is done by SunCulture Company, which has a dedicated team of 75 staff of which 60% are male and 40% female, based in various parts of the country. These include 16 full-time field-based technicians and 30 field-sales agents who provide installation services to the customers after conducting surveys. The field agents work in, and report to regional representatives in, three main regions, namely Western, Central, and the Coastal Area.
Successful financial model
SunCulture operations are currently supported by grant funding, by income from sales, and by strategic partnerships. Key funding partners include the Shell Foundation, USAID, and Microsoft, among others. The company has also attracted investment from international institutions such as Energy Access Ventures and Partners Group, which has enabled them to add business management, to widen their geographic reach, and to recruit sector-specific partners.
