3HP Submersible Pump
A 3HP submersible pump costs ₹80,000 to ₹1,60,000 in the open market for a solar-powered unit, though under the PM-KUSUM government subsidy scheme, farmers can access the same capacity for as little as ₹35,000 to ₹53,926 depending on their state's subsidy structure. A submersible pump is designed to be fully submerged inside a borewell or deep water source, distinct from a surface (monoblock) pump which sits above ground and draws water through a suction pipe. This guide compares the 3HP submersible pump against its surface-pump alternative, breaks down the subsidy math, and covers what actually determines whether 3HP is the right capacity for your borewell depth and water requirement.
3HP submersible pump at a glance
Parameter | Details |
Open market price (solar) | ₹80,000 to ₹1,60,000 |
Price under PM-KUSUM subsidy | ₹35,000 to ₹53,926 (state-dependent) |
Typical subsidy coverage | 60% to 90% of total system cost |
Water output | Up to 50,000 litres per day (site-dependent) |
Suitable water depth | Deep borewells, typically beyond 15 metres |
Power source options | Solar DC, solar AC (with inverter), grid AC |
Warranty | Typically 5 years under subsidised schemes, including maintenance |
Submersible vs surface (monoblock) pump: which do you need?
Factor | Submersible pump | Surface (monoblock) pump |
Installation | Fully submerged inside borewell/well casing | Sits above ground, draws water via suction pipe |
Water source depth | Deep borewells (15+ metres) | Shallow sources: ponds, canals, open wells, shallow borewells |
Motor cooling | Water-cooled (surrounding water cools motor) | Air-cooled |
Efficiency at depth | High, designed specifically for deep lift | Poor beyond 7-8 metres suction limit |
Typical use case | Agricultural borewells, deep groundwater extraction | Surface water bodies, shallow wells, irrigation canals |
Price (3HP DC) | ₹80,000 to ₹1,60,000 | ₹53,926 under Haryana HAREDA scheme (example) |
If your water source is a deep borewell, submersible is the only practical option since surface pumps cannot effectively lift water from significant depths. If you're drawing from a pond, canal, or shallow open well, a surface/monoblock pump is often more cost-efficient.
PM-KUSUM subsidy structure for 3HP submersible pumps
PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) Component B specifically targets solar pump subsidies for individual farmers:
Subsidy contributor | Coverage | Example (Haryana) |
Central government (MNRE) | 30% | Part of total subsidy |
State government (varies) | 30% to 60% (state-dependent) | Haryana: 45% |
Farmer contribution | 10% to 40% (state-dependent) | Haryana: 25% (₹53,926 for 3HP DC surface pump) |
Example from Haryana's HAREDA scheme: A 3HP DC surface (monoblock) pump with normal controller costs ₹53,926 to the farmer after subsidy, out of a full market price significantly higher before subsidy support.
Subsidy percentages and exact farmer contribution amounts vary considerably by state, so always confirm current rates through your state's renewable energy agency (like HAREDA in Haryana, MEDA in Maharashtra, or equivalent bodies elsewhere) rather than relying on a single national figure.
3HP solar system price: complete system vs pump alone
Component | Price range |
3HP pump unit alone | ₹80,000 to ₹1,60,000 |
Complete 3HP solar system (panels + pump + controller) | ₹1,75,000 to ₹2,45,000 before subsidy |
Same complete system after PM-KUSUM subsidy | ₹35,000 to ₹70,000 (depending on state subsidy tier) |
The "3HP submersible pump price" people search for often refers to just the pump/motor unit, but a functioning solar pumping system also requires solar panels (roughly matching the 3kW capacity), a controller, and mounting structure, which is why the complete system price is meaningfully higher than the pump-alone figure.
How to choose the right pump capacity for your borewell
Factor | What to check |
Water table depth | Deeper water requires higher HP for adequate lift, not just higher output |
Required daily water output | Match to your irrigation area and crop water needs, not just borewell capacity |
Static vs dynamic water level | Dynamic level (while pumping) matters more than static level for correct sizing |
Pipe diameter and length | Affects friction loss, which impacts effective pump performance regardless of rated HP |
A common and costly mistake: choosing pump HP based on budget alone without matching it to your borewell's actual depth and discharge characteristics. An undersized pump for a deep borewell will underperform regardless of its rated capacity on paper.
Maintenance tips for 3HP solar submersible pumps
- Clean solar panels regularly (dust accumulation reduces generation and pump performance)
- Check wiring connections periodically for corrosion, especially in humid or coastal regions
- Avoid running the pump dry (without adequate water level), which can damage the motor
- Flush the system occasionally to prevent sediment buildup in the pump mechanism
- Keep the controller unit protected from direct weather exposure if not rated for outdoor conditions
With proper maintenance, a 3HP DC submersible or monoblock pump can operate reliably for 10+ years.
FAQs
What is the price of a 3HP submersible pump in India?
A 3HP submersible pump costs ₹80,000 to ₹1,60,000 in the open market for a solar-powered unit. Under the PM-KUSUM subsidy scheme, farmers can access the same capacity for ₹35,000 to ₹53,926 depending on their state's subsidy structure.
What is the difference between submersible and surface solar pumps?
Submersible pumps are fully submerged inside a borewell and are designed for deep water extraction (15+ metres). Surface (monoblock) pumps sit above ground and draw water via suction pipe, suitable only for shallow sources like ponds, canals, or shallow wells up to about 7-8 metres depth.
How much subsidy is available for a 3HP solar pump under PM-KUSUM?
Subsidy coverage ranges from 60% to 90% of total system cost depending on your state, with the central government contributing 30% and state governments adding varying additional percentages. Farmer contribution typically ranges from 10% to 40% of total cost.
How much water can a 3HP solar pump deliver daily?
A 3HP solar pump can deliver up to approximately 50,000 litres of water per day, though actual output depends significantly on borewell depth, water table conditions, sun-hours available, and pipe specifications.
Is a 3HP pump enough for my borewell?
It depends on your water table depth and required daily discharge, not just borewell existence. Deeper water tables or higher irrigation area requirements may need a higher HP rating. Consult a local solar pump installer to assess your specific site conditions before finalising capacity.
How to apply for PM-KUSUM subsidy for a 3HP solar pump?
Applications are processed through your state's renewable energy development agency (HAREDA in Haryana, MEDA in Maharashtra, and equivalent bodies elsewhere). Check your state agency's website for open application windows, required documents, and eligibility criteria, since these vary by state and application periods open periodically.
What is the difference between a 3HP DC and AC solar pump?
DC pumps run directly on solar panel output without needing a separate inverter, generally offering higher efficiency for solar applications. AC pumps require an inverter to convert solar DC power to AC, adding a component but allowing compatibility with standard AC motor pumps also usable on grid power as backup.
How long does a 3HP solar submersible pump last?
With proper maintenance, including regular panel cleaning, avoiding dry running, and periodic wiring checks, a 3HP solar submersible pump typically operates reliably for 10+ years, with many government subsidy schemes including 5 years of maintenance support as part of the package.
