What type of installation?
Helical rotor pumps suit lower flow at higher head in narrow bores; centrifugal pumps suit higher flow. Surface pumps sit above ground.
Bore size & pump technology
The pump must fit down your borewell. Helical suits 3" and above; centrifugal suits 4" and above.
Project location
We'll pull the average solar irradiance for your site from NASA POWER to estimate how much water the pump can lift per day. This step is optional — skip it to size on head & flow alone.
Dealer / Distributor & customer details Optional
Skip — not neededHow high must the water be lifted?
Total head in metres — water level to delivery point, plus pipe friction.
How much water do you need?
Duty flow at your head, in cubic metres per hour (m³/h). Litres per minute shown too.
Select your solar PV panel
Pick a common panel size or enter your own electrical specifications. We'll use this to size the array and controller compatibility for your recommended pump(s) on the results page.
You'll see the full array sizing, controller compatibility and wiring diagram on the results page, for both your recommended pump and the secondary recommendation.
Guidance based on the Roto Rudra Solar Pumping Solutions catalogue (updated 30 June). Solar output varies with sunlight, panel wattage and actual head; confirm final sizing, panel array and controller with a Roto Rudra dealer. Helical pumps suit clean water at +20 to +30 °C; centrifugal 0–40 °C, max sand 50 g/m³.
