7.5 HP Solar Pump in India: Price, Specs & Deep Borewell Guide

A 7.5 HP solar pump costs ₹2,80,000–₹3,60,000 before subsidy and is the largest pump size eligible for KUSUM Yojana Component B. It delivers 3,00,000–4,50,000 litres per day and handles deep borewells up to 500 feet — making it ideal for large farms (8–15 acres) and regions with deep water tables. After KUSUM subsidy, farmers pay ₹84,000–₹1,44,000.

• Large farmers (8–15 acres) — growing water-intensive crops like sugarcane, paddy, or banana
• Very deep borewells (400–500 feet) — common in Rajasthan, Karnataka plateau, Vidarbha, and parts of Tamil Nadu
• High daily water demand — farms with multiple crop zones needing 3+ lakh litres per day
• Farmer cooperatives — shared pump serving a village community borewell
• KUSUM maximum benefit — since 7.5 HP is the subsidy ceiling, it offers the highest absolute subsidy value

If your borewell is under 300 feet and farm under 8 acres, a 5 HP pump is more cost-efficient. For borewells deeper than 500 feet or farms over 15 acres, a 10 HP pump is needed (though subsidy is capped at 7.5 HP).

A 7.5 HP system needs 9.0–11 kW of solar panels — 17 to 20 panels arranged in 2–3 rows on a ground-mount structure.

• Ground space: 350–500 sq ft (roughly 15m × 3m)
• Structure: heavy-duty galvanised steel ground mount with concrete foundations
• Cabling: thicker DC cables (6mm² or 10mm²) to handle higher current
• Controller: industrial-grade VFD with MPPT, typically 7.5–10 kW rated

The panel area is significant — plan the location carefully to avoid shading from trees, buildings, or other structures. Many farmers dedicate a corner of the field or use boundary land for the panel array.

7.5 HP is the ceiling for KUSUM Component B standalone solar pumps. This means:

• Central subsidy: 30% of benchmark cost ≈ ₹84,000–₹1,08,000
• State subsidy: 30% ≈ ₹84,000–₹1,08,000
• Farmer share: 40% ≈ ₹1,12,000–₹1,44,000

At 7.5 HP, you get the highest absolute subsidy amount under KUSUM — over ₹2,00,000 in combined subsidies. If you need more than 7.5 HP, a 10 HP pump is available but the additional cost above 7.5 HP is unsubsidised under Component B.

A 7.5 HP system is a significant investment. Get it right with a professional site survey — borewell depth test, yield assessment, and TDH calculation. Solar Vipani connects you with verified, KUSUM-empanelled dealers.
