4R Digital, in partnership with Davis & Shirtliff, aims to bring affordable, climate-smart solar irrigation solutions to up to 35,000 smallholder farmers in Kenya – spurring the transition away from unsustainable and inefficient hand, petrol and diesel pumps. With support from PREO, 4R Digital has developed and trialled a digital Pay-As-You-Go (PAYGO) platform to be incorporated into pre-existing solar pumping kits, supplied by Davis & Shirtliff. In addition to providing a payment facility, the platform also allows for remote monitoring and locking of the equipment whilst providing full visibility to customers of their own financial data through the account management system.
