Introduction
Buying a solar pump is a long-term investment. The right
pump will serve your farm for 20+ years. The wrong one will underperform, cost
more in repairs, and leave your crops short of water. This guide walks you
through every factor to consider when choosing a solar pump for Noida.
Step 1: Determine Your Water Requirement
Start by calculating how much water your farm needs per day.
Consider:
• Total
irrigated area (acres or hectares)
• Crop
type (paddy needs more water; drip crops need less)
• Irrigation
method (flood, drip, sprinkler)
• Peak
season daily requirement
A general rule: 1 HP solar pump delivers approximately
40,000–60,000 litres per day under good sunlight conditions.
Step 2: Understand Your Borewell Depth
The depth of your borewell determines the pump and motor
size you need:
• Up
to 30m — Surface pump or shallow submersible
• 30–60m
— 1–2 HP submersible pump
• 60–100m
— 2–3 HP submersible pump
• 100m+
— 3–5 HP or helical rotor system
Step 3: Choose the Right Pump Type
Centrifugal Submersible Pumps — Best for clean
water, moderate depth, high-flow requirement.
Helical Rotor Pumping Systems — Best for deep
wells, sandy/silty water, and consistent flow.
NEO Series Pumps — Best for standard bore
wells up to 60m, energy-efficient.
Step 4: Select the Right Motor
PMSM (Permanent Magnet Synchronous Motors) are the most
energy-efficient motors for solar pumps. Roto RUDRA offers:
3" PMSM Motors — For narrow 4"
borewells
4" PMSM Motors — Most common, suits most
Indian farm borewells
6" PMSM Motors — For high-capacity
commercial applications
Step 5: Pick the Right Solar Controller
The solar controller manages power between panels, battery,
and motor. Roto RUDRA offers three options at Solar Controllers:
• Off-Grid
Controller — No grid connection needed, runs entirely on solar
• Hybrid
Controller — Can use solar + grid power for uninterrupted supply
• On-Grid
Controller — Exports excess solar power back to grid
Step 6: Check for Subsidy Eligibility in Noida
In India, the PM-KUSUM scheme offers 60–90% subsidy. Many
states in Noida also have similar agricultural energy programmes. Check
with your local agricultural department or Roto RUDRA dealer to know what is
available.
Conclusion
Choosing the right solar pump requires matching depth, flow,
motor size, and controller to your specific farm needs. Roto RUDRA's technical
