Solar power adoption in India has accelerated over the past decade, driven by supportive government policies, improving affordability of solar panels and climate change considerations. A key aspect spurring Solar Panel Prices in India with Subsidy – capital incentives provided to make solar power systems more affordable for homes, businesses, farmers and institutions.

In this comprehensive guide, we analyze solar panel prices in India across various states, the subsidy benefits applicable for 2024 and everything you need to know about the financial schemes accelerating solar adoption.

What are Solar Panel Subsidies?

Solar panel subsidies refer to financial incentives given by central and state governments in India to increase adoption of photovoltaic (PV) solar power systems. They are usually provided as:

1) Capital Subsidies: Direct upfront incentives on the initial purchase and installation costs of solar panels and related components. This lowers the entry price barrier for going solar.

2) Feed-in Tariffs: Preferential rates paid by electricity distribution companies to rooftop solar producers when excess solar power is exported to the grid. Higher than retail power rates.

3) Tax/Duty Exemptions: Relief from certain import, excise and GST duties applicable to the solar value chain – manufacturing, sale and consumption.

These solar subsidies combined with falling global panel prices have made solar power adoption highly viable for residential, commercial and industrial categories in India. The incentives can cover anywhere from 20% to 60% of the initial capital expenditure when investing in rooftop solar. Let’s take a closer look at the national and state-level solar subsidy programs.

Central Financial Assistance for Rooftop Solar

The Ministry of New and Renewable Energy has been running the Grid Connected Rooftop Solar program since 2013. It provides Central Financial Assistance (CFA) or subsidies to residential, institutional and private organizations setting up rooftop solar panels.

As of 2022, around 7,200 MW of decentralized solar capacity has been sanctioned under the program. The plan is to reach 40,000 MW by 2022, hence aggressiveuptake is essential. That’s where subsidies play a pivotal role by improving solar’s value proposition.

Here is an overview of the CFA benefits:

Category Subsidy Rate

Residential 40%
Institutional 20%
Government Organizations 40%

Commercial/Industrial 30%

So a 30-40% base subsidy is provided from the center for rooftop solar installations up to 10 kw capacity. Additionally, state governments also offer incentives over and above this CFA which can sweeten the deal further. Let’s take a look at state-wise solar subsidies and exact panel rates next.

State-wise Solar Panel Prices and Subsidies

Many Indian states provide additional benefits for distributed solar installations by households, shops, offices etc. beyond the central subsidy grants. These include higher feed-in tariffs for solar power exports, low-interest financing, net metering incentives etc.

When combined with central assistance, the total subsidy grant can cover 40-60% of the initial solar system cost depending on your location. This significantly accelerates return on investment for solar power.

Here is a quick snapshot of solar panel rates across states for a 3 kw residential system along with applicable subsidy benefits:

▪ Rajasthan

3 kw Solar Panel Price: ₹1.2 lakhs
Subsidy Benefits: Up to 60%
Effective Price: ₹50,000

▪ Gujarat

3 kw Panel Price: ₹1.3 lakhs
Subsidy: 35%
Final Price: ₹84,500

▪ Maharashtra

3 kw Solar Panel Cost: ₹1.5 lakhs
Subsidy: 50%
Effective Price: ₹75,000

▪ Tamil Nadu

3 kw Panel Rate: ₹1.4 lakhs
Subsidy: 55%
Final Expense: ₹63,000

As you can see, the net outlay for solar panels after claiming subsidies reduces quite drastically across states, catalyzing faster paybacks.

Now let’s analyze solar panel prices, subsidies and returns in detail for different system capacities – 1 kw, 2 kw, 3 kw and 5 kw.

1 kw Solar Panel Rates and Subsidies

1 kilowatt or 1,000 watt solar panel systems are apt for very small loads like minimal lighting, a couple of fans, phone charging etc. Here are the indicative 1 kw solar panel price across India:

● Standalone 1 kw Panel Price: ₹55,000
● Standalone Price after 30% Subsidy: ₹38,500
● Expandable 1 kw Price: ₹45,000
● Expandable Price post Subsidy: ₹31,500

So thanks to central financial grants, the effective 1 kw solar panel investment comes down to ₹31,500 to ₹38,500 based on panel wattage and type.

Some states also allow residential consumers to claim higher CFA of 40% instead of standard 30% for commercial cases. This further lowers solar panel prices by 10%.

In terms of returns, 1 kw solar systems can save between ₹800 to ₹1,500 monthly on electricity bills when sized appropriately for self-consumption. The capital investment pays back in 4 to 6 years before providing free solar power for 15+ years.

While returns are modest, 1 kw panels act as great starter capacity before scaling up solar generation. You also reduce carbon footprint while buffering against rising grid power tariffs.

2 kw Solar Panel Rates and Incentives

For slightly larger loads like powering multiple lights, fans, TVs, refrigerator etc. a 2 kilowatt solar system is apt. Here are the market price and post-subsidy outlays:

● Basic 2 kw Solar Panel Price: ₹1 to ₹1.25 lakhs
● Effective Price post 30% Subsidy: ₹70,000 to ₹87,500

In terms of energy savings, a right-sized 2 kw system can reduce monthly electricity expenses by ₹2,000 to ₹4,000. The capital investment pays back in 4 to 5 years before delivering free solar power for 20+ years. A great balance of solar self-sufficiency and returns.

Some states like Rajasthan, Tamil Nadu and Maharashtra offer additional 10-20% subsidies for 2 kw home solar systems beyond the standard central assistance. This further accelerates ROI.

3 kw Solar Panel Rates and Incentives

For medium loads powering key home appliances or an office setup, a 3 kilowatt solar system hits the sweet spot. Here is an overview of market rates and post-subsidy outlays:

● 3 kw Solar Panel Standalone Cost: ₹1.5 lakhs
● Subsidy Amount @30%: ₹45,000
● Effective System Price: ₹1.05 lakhs

In terms of returns, a properly designed 3 kw solar system can save between ₹4,000 to ₹7,000 monthly on grid electricity bills through self-consumption. The capital investment pays back within 4 years before delivering free solar power for 20+ years.

In states like Rajasthan, Gujarat, Tamil Nadu etc. additional 10-20% state incentives can further lower the 3 kw solar panel rates beyond the base CFA subsidies. Accelerating ROI.

5 kw Solar Panel Costs and Incentives

For larger household loads with multiple air conditioners or for commercial setups like shops and offices, a 5 kw solar system may be apt. Here is an overview of the 5 kw solar panel price and post-subsidy outlays:

● 5 kw Solar Panel Standalone Price: ₹2.5 lakhs
● 30% Subsidy Amount: ₹75,000
● Effective System Price: ₹1.75 lakhs

Properly designed 5 kw solar power systems can save between ₹7,000 to ₹12,000 monthly on grid electricity bills, with surplus solar power also being sold back to the utility.

The 5 year returns are very lucrative with the capital investment paying back within 3-4 years in most states before delivering free, green energy for 20-25 years.

In states like Rajasthan, Kerala, Gujarat – additional 10-20% state grants can further reduce effective solar panel prices and accelerate ROI.

So in summary, thanks to the generous federal and state solar subsidies, current rates across India for solar panels are:

● 1 kw Solar Panel Price: ₹31,500 to ₹38,500

2 kw Solar Panel Price: ₹70,000 to ₹87,500

● 3 kw Solar Panel Price: ₹1 to ₹1.2 lakhs

● 5 kw Solar Panel Price: ₹1.5 lakhs to ₹1.75 lakhs

Additional Solar Subsidies and Incentives

Apart from the upfront capital subsidies on solar systems, there are also a few other incentives provided by central and state agencies to catalyze adoption:

1. Accelerated Depreciation: Solar power systems can avail accelerated depreciation of 40% in the first year over and above the subsidies. This reduces tax liability.
2. Renewable Energy Certificates: Solar producers can avail additional revenues by selling the environment benefits of solar power in the form of RECs. 1 REC currently trades at ₹1,100.
3. Low Interest Project Financing: Banks and NBFCs offer financing for solar projects at preferential interest rates as low as 4-8%. This is 2-3x cheaper than retail loans.
4. Net Metering Incentives: Surplus solar units exported to the grid are compensated by discoms at ₹3-5/kWh in different states, higher than grid retail tariffs.
5. Third Party Ownership Models: No upfront solar investment needed. Just pay for solar energy generated every month at 4-8₹/kWh for next 15-20 years

So apart from direct subsidies, there are alternative incentives to improve the value proposition of solar power for any home, commercial establishment or institution.

Adoption Trends

Thanks to the strong policy backing, reducing solar panel prices and rising grid tariffs, rooftop solar uptake has grown at over 60% CAGR in India over the last 5 years.
