Power Your Farm with Solar – Eliminate Diesel & Electricity Dependency

Solar-powered agricultural pumps provide free, reliable water supply for farms. Cut fuel costs by 100%, increase crop yield, and achieve sustainable farming with government subsidies.

Why Solar Pumps for Agriculture?

Farmers face two critical challenges: high diesel/electricity costs for water pumping and unreliable grid power during critical irrigation periods. Solar pumps address both by providing free, abundant solar energy to power pumping 24/7, dramatically reducing operational costs and ensuring water availability when needed most.

Zero Fuel Cost

Eliminate 100% of diesel costs (typically ₹40,000-100,000/season). Massive savings directly to farmer's pocket.

Independence

No more waiting for grid power or buying expensive diesel. Water supply under farmer's control 24/7.

Increased Yield

Reliable water = consistent irrigation = better crop yield. Studies show 20-40% yield increase possible.

Profitability

Lower production costs improve profit margins. Better competitiveness in agricultural markets.

Sustainability

Eliminate emissions, protect environment, build sustainable farm business for future.

Government Subsidy

50-90% subsidy available (PM-KUSUM, state schemes). Minimal farmer investment required.

Understanding Agricultural Water Needs

Calculating Your Farm's Water Requirements

Step 1: Farm Profile Analysis

Key Information Needed:
– Total farm area (hectares/acres)
– Crop types and varieties
– Soil type (affects water retention)
– Local climate and rainfall
– Current water source (borewell depth, surface water)
– Current pumping hours per day
– Irrigation method (flood, drip, sprinkler)

Step 2: Crop Water Requirement Calculation

SAMPLE CALCULATION: Sugarcane Farm, 5 Acres, Maharashtra

Crop Water Requirement:
– Sugarcane (kharif): 1,500-2,000 mm/season
– For 5 acres = 50,000 m²
– Total water needed: 75,000-100,000 m³/season
– Season duration: 5-6 months
– Daily average: 400-500 m³/day

Accounting for Monsoon Contribution (25% rainfall):
– Net irrigation need: 300-375 m³/day
– Pumping hours: 8 hours/day assumed
– Required flow rate: 37.5-46.9 m³/hour
– = 625-780 liters/minute

PUMP REQUIREMENT: 2-3 HP submersible pump sufficient

Crop	Peak Need	Typical Duration	Total Seasonal
Sugarcane	6-8mm/day	12-18 months	1,500-2,000mm
Cotton	4-6mm/day	5-6 months	600-1,000mm
Maize	5-7mm/day	4-5 months	600-800mm
Vegetables	3-5mm/day	3-6 months	400-700mm
Pulses	2-4mm/day	4-5 months	400-600mm
Groundnut	3-5mm/day	4-5 months	500-750mm

Accounting for Efficiency Losses:
Theoretical water need: 375 m³/day
System efficiency losses:
– Pipe friction: -5%
– Pump inefficiency: -5%
– Evaporation/seepage: -10%
Total losses: -20%

Actual system size needed: 375 ÷ 0.80 = 468 m³/day
At 8 hours pumping: 58.5 m³/hour = 975 liters/minute
= 2.5 HP pump (practical)

Frequently Asked Questions

Will solar pump work during monsoon or cloudy days?

Yes. Panels generate even on cloudy days (40-60% efficiency). During heavy monsoon, generation reduces but continues. Most farmers not need water during peak monsoon.

What if borewell is very deep (300+ meters)?

Possible with higher HP pump. We assess depth and recommend appropriate system. Deeper wells need more powerful pump but solar handles it.

Can I pump water for both irrigation AND drinking?

Yes! Same pump can fill tanks for multiple uses. Some farmers dedicate portion for village drinking water supply (create community benefit).

What if I have multiple water sources (well + pond)?

Design system to switch between sources. One pump can serve both via valve switching. Maximizes flexibility.

How do I handle water storage?

Tank size calculated based on daily need and sun hours. Storage tank holds daytime generation for evening/early morning use. Prevents waste.

What about monitoring—how do I know if system works?

Manual check: Water delivery indicators. Optional: Real-time monitoring app on mobile (premium feature). Most farmers check visually.

Is 2 HP sufficient for my farm?

Depends on farm size, crops, water table depth. We assess and recommend right capacity. Usually 1-3 HP sufficient for small farms.

Can system handle livestock watering?

Absolutely! Many farmers use for both irrigation + livestock drinking. System scaled to include both uses.

What if I want to expand later?

Easy to add more panels or upgrade pump if farm expands. System modular and scalable (within structural limits).

How do I claim government subsidy?

We handle entire subsidy process. Provide documents, submit application, follow up with authorities. Farmer simply waits for approval.
