Solar Pumps (Agriculture)
A solar agriculture pumping system uses clean photovoltaic technology to convert sunlight into electricity, allowing farmers to run highly efficient irrigation networks without relying on unpredictable grid power or expensive diesel generators.
1. Pump Types: Submersible vs. Monoblock (Surface) Pumps
The selection between these two primary configurations depends entirely on the depth of the water source.
Submersible Solar Pumps
Installation: Fully lowered and submerged inside a deep well or borewell.
Operation: Pushes water upward rather than pulling it.
Best Used For: Deep groundwater extraction (typically depths from 15 meters to over 200 meters). It is the standard choice in regions with low water tables.
Monoblock (Surface) Solar Pumps
Installation: Installed above ground next to the water source.
Operation: Draws water upward through a suction pipe. The driving motor and pump impeller share a single, perfectly aligned shaft.
Best Used For: Shallow water sources like open wells, ponds, canals, lakes, and storage tanks. They are limited to pulling water from maximum depths of about 7 to 8 meters.
2. Water Delivery Capacity by Horsepower (HP)
Water output varies based on total dynamic head (depth + delivery height) and peak solar radiation. Below is the standard water delivery breakdown typically outlined under national agricultural initiatives like PM-KUSUM for daily discharge under optimal sunshine:
| Model Capacity | Recommended Source / Depth Range | Average Peak Hourly Output | Average Daily Discharge (6–7 hours sun) |
|---|---|---|---|
| 3 HP | Open wells or shallow borewells (up to 30–50 meters) | ~6,000 to 7,500 Litres | 40,000 to 50,000 Litres |
| 5 HP | Medium-depth borewells (up to 70–100 meters) | ~9,500 to 11,000 Litres | 65,000 to 80,000 Litres |
| 7.5 HP | Deep borewells & larger holdings (up to 100–130 meters) | ~14,000 to 16,500 Litres | 1,00,000 to 1,20,000 Litres |
| 10 HP | Very deep borewells & large-scale farming (130 to 150+ meters) | ~22,000 to 28,000 Litres | 1,50,000 to 2,00,000+ Litres |
