PMSM Solar Pumps
Permanent Magnet Synchronous Motors (PMSM) represent the highest performance class of solar water pumps — delivering greater than 90% motor efficiency with superior discharge per kW input.
PM-KUSUM Scheme — Up to 60% Subsidy for Farmers!
Under the Government of India's PM-KUSUM scheme, eligible farmers can get up to 60% subsidy on solar water pump installations. We assist with all documentation and approvals from start to finish.
Check EligibilityWhy Choose PMSM Technology
Permanent Magnet Motor
Synchronous motor with permanent magnets delivers industry-leading efficiency exceeding 90% across the full load range.
Higher Discharge per kW
PMSM technology delivers more water output per kilowatt of solar input compared to conventional motor types.
Wide DC Input Window
Stable pump output across varying sunlight levels. Continues to operate effectively even during partial cloud cover.
Excellent Part-Load Performance
Maintains high efficiency and stable output even when operating at partial load during early morning or late evening hours.

Where PMSM Pumps Work Best

Agriculture Irrigation
Drip irrigation, sprinkler systems, and flood irrigation for paddy, sugarcane, wheat, and other field crops requiring high-volume water supply.

Community Water Projects
Village-level water supply schemes, Panchayat water projects, and community tanks requiring robust and continuous performance.

Deep Borewells
High head installations with deep water tables where conventional pumps struggle — PMSM handles up to 140m head reliably.

I have 15 acres of sugarcane and needed a powerful pump for deep borewell irrigation. SIA Solar's 5 HP PMSM pump handles 140m head perfectly. Water output is consistent even on cloudy days. Very impressive technology!
Our Panchayat installed a 4 HP PMSM solar pump for the village water scheme. It pumps water continuously from 100m depth to an overhead tank. No electricity bills, no load shedding issues. The whole village is happy!
We switched to a 3 HP PMSM pump for drip irrigation on our paddy farm. We also got the PM-KUSUM subsidy through SIA Solar’s team. The efficiency is remarkable — more water per kilowatt than anything we used before.
