Start with the site
For farms and rural sites evaluating solar-powered water pumping or an existing pump conversion.
Horsepower alone is not a design
Two pumps with the same motor rating can deliver very different flows at different heads. Start with the water volume needed each day, the well or borewell conditions, delivery height, pipe length and irrigation method. Seasonal changes in the water level should be included in the duty assessment.
The source must be able to supply the required flow. Solar capacity cannot compensate for a low-yield borewell or unsuitable pipework. An existing pump may be reusable, but its nameplate, operating condition and compatibility with the proposed controller need checking.
Match pumping hours to the irrigation plan
Direct solar pumping varies with available sunlight. The irrigation schedule, crop water requirement and seasonal demand should guide whether daytime pumping fits the site. Where practical, water storage can help separate the time water is pumped from the time it is used.
Review the array location for shade, safe access, cable distance and protection from accidental damage. The proposal should identify the pump, controller, structure, pipework, cabling and protective devices included, along with the work expected from the owner.
Separate the technical plan from any scheme enquiry
First establish a technically suitable solution and a clear written scope. If you intend to apply through a government programme, confirm the current application route, vendor requirements and applicable conditions with the responsible authority before committing.
Tell us whether this is a new installation, replacement or conversion of an existing electric or diesel pumping arrangement. A site assessment can then focus on the actual equipment and water duty rather than assuming one standard package fits every farm.
