Problem

High upfront equipment costs make solar irrigation difficult for smallholder farmers to invest in.
Limited access to suitable financing reduces farmers’ ability to purchase solar irrigation systems without paying the full cost upfront.
Inadequate sales and after-sales services limit access to pump selection advice, technical support, spare parts, and repairs.
Limited market availability of solar-powered pumps restricts farmers’ access to solar irrigation compared with petrol, diesel, and other traditional options.
Limited access to solar irrigation reduces farmers’ ability to produce crops throughout the year and limits the potential use of solar irrigation in farming businesses.

Solution

Flexible payment options such as PAYGO and PAYOWN reduce the need for farmers to pay the full equipment cost upfront.
Tailored payment arrangements adapt payment amounts and frequency to farmers’ ability to pay, improving access to solar irrigation.
Sales and after-sales services provide pump suitability advice, installation support, warranties, spare parts, repairs, and technical assistance.
Sales and service networks improve access to solar-powered pumps and create stronger connections between farmers, suppliers, and service providers.
Solar-powered irrigation provides an alternative to petrol and diesel pumps, helping farming businesses support year-round crop production.

Scaling Readiness describes how complete a technology\’s development is and its ability to be scaled. It produces a score that measures a technology\’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.
