How Solar Panel Prices in India Are Structured in 2026

Solar panel price in India is never just the cost of the panels.

The total installed cost includes panels, inverter, mounting structure, wiring, installation labour, and grid connectivity fees.

Here is what goes into the final per-kW cost

• Solar panels (modules)

  50 to 60 percent of total system cost.

• Solar inverter

  15 to 20 percent of total cost.

• Mounting structure

  8 to 12 percent.

• Wiring, switchgear, and earthing

  5 to 8 percent.

• Installation and commissioning

  5 to 10 percent.

• Net metering and DISCOM charges

  Rs. 5,000 to Rs. 15,000 as a one-time cost.

Solar Panel Price in India 2026 Cost Per kW by System Type

The table below reflects real market prices for grid-tied solar systems without battery storage. These are installed costs, not just hardware.

Prices are indicative for 2026 market conditions. Actual quotes vary by state, brand, and site conditions.

What Factors Change the Solar Panel Price You Actually Pay?

Solar panel price per kW is not fixed. Several variables move the number up or down significantly.

Solar Panel Technology and Brand Tier Affect Cost by 20 to 35 Percent

• Monocrystalline PERC panels

  cost Rs. 22 to Rs. 28 per Wp and deliver 19 to 21 percent efficiency.

• TOPCon panels

  cost Rs. 25 to Rs. 32 per Wp and deliver 21 to 23 percent efficiency.

• Polycrystalline panels

  cost Rs. 16 to Rs. 20 per Wp but are losing market share due to lower efficiency.

For a rooftop with limited space, spending more on high-efficiency TOPCon panels delivers more kW from the same area.

Inverter Type Changes Both Price and Long-Term Reliability

The inverter converts DC solar power to AC power your appliances use. If you want to compare equipment quality before choosing, read best solar inverter brands India.

String inverters from brands like SolarEdge, Sungrow, Fronius, and ABB are the most common choice for residential and commercial systems in India today.

Your Location in India Affects Generation and Therefore Your Savings ROI

States with higher solar irradiation generate more units per kW installed.

• Rajasthan, Gujarat, Madhya Pradesh, Maharashtra 4.5 to 6.5 peak sun hours per day.

• Tamil Nadu, Karnataka, Andhra Pradesh 4.0 to 5.5 peak sun hours.

• West Bengal, Assam, Kerala 3.5 to 4.5 peak sun hours.

A 5 kW system in Rajasthan generates approximately 7,500 to 8,000 units per year. The same system in Kerala generates approximately 5,500 to 6,500 units. This directly affects your annual savings and payback period.

How Much Does a 3 kW, 5 kW, and 10 kW Solar System Cost in India in 2026?

System size is the most searched dimension of solar pricing because most buyers already have a rough idea of their consumption. Here is a detailed breakdown.

3 kW Solar System Price in India 2026

A 3 kW system suits a 2BHK or 3BHK home with monthly electricity consumption between 250 and 400 units. Buyers comparing this segment should also review residential solar system installation for homes in India.

• Installed cost (grid-tied, no battery) Rs. 1.50 lakh to Rs. 2.10 lakh.

• After PM Surya Ghar subsidy (applicable to systems up to 3 kW) subsidy of Rs. 78,000 is available for systems up to 3 kW.

• Net cost after subsidy approximately Rs. 72,000 to Rs. 1.32 lakh.

• Annual generation 3,600 to 4,800 units depending on location.

• Annual savings at Rs. 8 per unit grid tariff Rs. 28,800 to Rs. 38,400.

• Payback period post-subsidy 2 to 4 years.

For a typical middle-class Indian household, a 3 kW system with the PM Surya Ghar subsidy is the single best financial investment available today.

5 kW Solar System Price in India 2026

A 5 kW system suits large homes, independent bungalows, or small offices consuming 500 to 800 units per month.

• Installed cost (grid-tied, no battery) Rs. 2.20 lakh to Rs. 3.50 lakh.

• PM Surya Ghar subsidy applies partially (Rs. 78,000 for the first 3 kW, reduced rate for remaining 2 kW).

• Annual generation 6,000 to 8,000 units.

• Annual savings at Rs. 8 per unit Rs. 48,000 to Rs. 64,000.

• Payback period 4 to 6 years.

10 kW Solar System Price in India 2026

A 10 kW system suits commercial shops, clinics, small factories, and apartment common areas. Businesses comparing this size should review commercial solar installation for businesses.

• Installed cost (grid-tied) Rs. 3.80 lakh to Rs. 5.50 lakh.

• No residential subsidy at this capacity under PM Surya Ghar.

• Annual generation 12,000 to 16,000 units.

• Annual savings at Rs. 8 per unit Rs. 96,000 to Rs. 1.28 lakh.

• Payback period 3 to 5 years for commercial consumers at higher tariff slabs.

What Is the PM Surya Ghar Muft Bijli Yojana Subsidy and How Does It Reduce Your Cost?

The PM Surya Ghar Muft Bijli Yojana is the Government of India's flagship residential solar subsidy program that directly reduces the upfront cost of rooftop solar for homeowners.

PM Surya Ghar Subsidy Slab Structure in 2026

Key points to understand

• Subsidy is credited directly to the homeowner's bank account after system commissioning and DISCOM inspection.

• Only systems installed by empanelled vendors under the PM Surya Ghar portal qualify.

• The scheme targets 1 crore households and remains active through 2026 with strong budget allocation.

• Some states like Gujarat and Maharashtra offer additional state subsidies on top of the central amount.

For a homeowner installing a 3 kW system at Rs. 1.80 lakh, the Rs. 78,000 subsidy brings the net investment to Rs. 1.02 lakh. At Rs. 8 per unit grid tariff, that investment pays back in under 3 years.

On-Grid vs Off-Grid vs Hybrid Solar Which System Type Should You Choose?

Choosing the wrong system type is one of the most common and costly mistakes in solar buying. Each type serves a different need.

For a deeper comparison, see on grid vs off grid vs hybrid solar. If you want backup-ready equipment, explore WAVE hybrid inverter solutions.

Comparison of Solar System Types for Indian Homes and Businesses

On-grid systems are the best financial choice for urban and semi-urban locations where grid power is available most of the day. They have the lowest cost, generate credits through net metering, and deliver the fastest ROI.

Off-grid systems make sense where grid connectivity is absent or highly unreliable. They cost 60 to 80 percent more than on-grid systems due to battery banks.

Hybrid systems combine the best of both they export excess power to the grid and provide backup during cuts. They suit homes in Tier 2 and Tier 3 cities where outages of 2 to 6 hours per day are common.

How to Calculate the Right Solar System Size for Your Home or Business

You do not need to guess your system size. A simple formula gives a reliable starting point.

Step-by-Step Method to Size Your Solar System

1. Find your average monthly electricity consumption from your last 3 bills (in kWh or units).

2. Divide by 30 to get daily consumption. Example 300 units per month divided by 30 = 10 units per day.

3. Divide daily consumption by average peak sun hours in your city. Example 10 units divided by 5 hours = 2 kW.

4. Add 20 percent buffer for system losses and future load growth. Example 2 kW multiplied by 1.2 = 2.4 kW.

5. Round up to the nearest standard size 2.5 kW or 3 kW.

For a factory or commercial building, the same formula applies but your daily consumption may be 200 to 5,000 units, leading to systems in the 50 kW to 1 MW range.

A reliable solar EPC partner will run a detailed load analysis rather than guessing. Any installer who quotes a system size without reviewing your electricity bills is cutting corners.

What Are the Real Savings and ROI Numbers for Solar in India in 2026?

Solar ROI in India is among the best available in any passive investment class for both homes and businesses. For more detailed ROI benchmarks, visit solar payback period India 2026.

Savings Scenario for a 5 kW Residential System in Maharashtra

• System cost Rs. 2.80 lakh (installed, grid-tied).

• PM Surya Ghar subsidy applicable Rs. 78,000 (subsidy capped at 3 kW equivalent).

• Net investment Rs. 2.02 lakh.

• Annual generation approximately 7,000 units.

• Grid tariff Rs. 9 per unit (Maharashtra residential HT slab).

• Annual savings Rs. 63,000.

• Simple payback period approximately 3.2 years.

• Savings over 25-year system life (at current tariffs, not accounting for tariff increases) Rs. 15.75 lakh.

Every 5 percent annual increase in grid tariff improves the effective ROI because solar cost per unit stays flat while grid cost rises.

How Solar ROI Differs Between Residential and Commercial Consumers

Commercial and industrial consumers benefit even more from solar because they pay higher tariffs.

A factory paying Rs. 10 per unit for grid power and installing a 500 kW rooftop system at Rs. 2.80 per unit effective solar cost saves Rs. 7.20 per unit.
