A 3 kW solar panel system in India costs around ₹2.30–₹2.50 lakh, produces 12–15 units of electricity per day, needs 250–300 sq.ft of rooftop space, and comes with a ₹78,000 government subsidy under the PM Surya Ghar Muft Bijli Yojana
In a world where energy bills continue rising as steadily as the sun itself, a sustainable and cost-effective solution stands out — a 3kW solar power system. Whether you’re a homeowner looking to reduce electricity expenses or a business exploring greener alternatives, these systems offer a perfect balance of affordability and performance.
This blog covers 3kW solar panels, explaining how they work, their benefits, price breakdown, specifications, installation requirements, government subsidies, and how Freyr Energy supports your solar journey.
Understanding the Working of a 3kW Solar Power System
A 3kW solar power system is a moderate-sized installation capable of generating enough electricity to meet the needs of a small home or business. It typically consists of 8–10 solar panels, an inverter, mounting structures, and required wiring.
How a 3kW Solar System Works
- Solar panels absorb sunlight and generate DC (Direct Current).
- The inverter converts this DC into AC (Alternating Current) for home use.
- Surplus electricity is fed back to the grid (on-grid system), helping reduce overall consumption.
- A 3kW system can generate 12–15 units per day, depending on sunlight conditions.

3kW Solar Panel System Specifications, Installation, and Panel Types
- Monocrystalline: High efficiency, sleek design, ideal for limited roof space.
- Polycrystalline: More affordable, slightly lower efficiency, needs more space.
- TOPCon: Advanced technology, highest efficiency, long-term reliability.
- Bifacial: Captures sunlight from both sides, best for ground-mounted or large setups.
- Thin-Film: Low efficiency, niche use, rarely used for homes.
Installation Process and Space Requirements
- Typically installed on rooftops or open yards.
- Requires 250–300 sq. ft. of shadow-free space for a 3kW system.
- Proper tilt angle and south-facing orientation are crucial to maximize efficiency.
Factors Affecting 3kW Solar Panel Price in India
- Solar Panel Type: High-efficiency monocrystalline panels cost more, while polycrystalline panels are more affordable but slightly less efficient.
- Inverter Quality: Premium inverters improve energy conversion and system performance, but they increase the overall cost.
- Installation Type and Complexity: Rooftop solar installations are simpler and cheaper, whereas ground-mounted or complex roof systems cost more due to extra labor and materials.
- Location and Sunlight Availability: Regions with less sunlight may require more panels to achieve the same energy output, affecting the total cost.
- Government Subsidy: Under the PM Surya Ghar Yojana, residential consumers in India can avail financial assistance for installing rooftop solar systems, including a subsidy for a 3kW solar system, which significantly reduces the upfront investment.
- Energy Requirements: The higher your electricity consumption, the larger the system you may need, which impacts the overall price.
