30kW Solar Panel Price in India with ₹78,000 Government Subsidy

As India rapidly moves toward clean and sustainable energy, solar power has become one of the most practical and affordable energy solutions for homes, businesses, schools, and industries. Among various system capacities, the 30kW solar panel system stands out as a powerful and cost-effective choice for medium to large-scale electricity users.

In this detailed guide, we’ll explore everything you need to know about the 30kW solar system in India — including its price, specifications, subsidy, benefits, ROI, and much more.

What is a 30kW Solar System?

A 30kW solar panel system is a mid-size solar power setup capable of generating approximately 120–150 units of electricity per day, depending on factors such as sunlight availability, geographic location, and panel efficiency.

This capacity is ideal for:

• Small to medium-scale industries
• Educational institutions
• Hospitals
• Commercial buildings
• Large residential properties
• Government and agricultural setups

By installing a 30 kilowatt solar system, users can drastically reduce electricity bills while supporting India’s transition to renewable energy.

Types of 30kW Solar Panel Systems

Before understanding prices and benefits, it’s essential to know the three main types of solar systems available in India. The choice depends on your power requirements and grid availability.

1. On-Grid 30kW Solar System

This type is connected to the main power grid. When your solar panels generate more energy than you consume, the excess power is exported to the grid, earning you credit under the net metering policy.

Best for: Businesses and commercial setups with reliable grid connections.
Battery Requirement: No
Average Daily Generation: 120–150 units
Major Benefit: Reduces electricity bills up to 90%

2. Off-Grid 30kW Solar System

An off-grid system operates independently from the electricity grid. It uses batteries to store excess power for use at night or during cloudy weather.

Best for: Rural areas or places with unreliable grid supply.
Battery Requirement: Yes
Major Benefit: Complete energy independence

3. Hybrid 30kW Solar System

A hybrid system combines the features of both on-grid and off-grid systems. It can work with or without the grid, using batteries for backup and exporting surplus power when available.

Best for: Commercial or residential setups seeking reliability and efficiency.
Battery Requirement: Optional
Major Benefit: Continuous power supply and net metering benefits

30kW Solar System Price in India

Here’s an estimated cost breakdown as of 2025:

Note: Prices may vary slightly depending on brand (like Bluebird Solar, Waaree, Tata Power Solar, or Vikram Solar), panel type (mono PERC, bifacial, or TOPCon), inverter quality, and local installation charges.

30kW Solar Plant Price Calculation

Let’s take an example to understand the 30kW solar plant price in more detail.

Cost Breakdown (Approximation)

• Solar Panels: ₹10,50,000
• Solar Inverter: ₹2,00,000
• Mounting Structure: ₹1,00,000
• Wiring, BOS & Installation: ₹1,00,000 – ₹1,50,000
• Total Estimated Cost: ₹14,50,000 – ₹16,50,000 (for an on-grid system)

Electricity Savings

• Daily Power Generation: 120–150 units
• Monthly Generation: ~3,600–4,500 units
• Monthly Savings: ₹25,000–₹40,000 (depending on local electricity tariff)
• Payback Period: 3–4 years

After the payback period, the electricity you generate is practically free for the next 20+ years.

Government Subsidy for 30kW Solar System

The Indian government encourages solar adoption under various schemes, such as the PM Surya Ghar Muft Bijli Yojana and the National Rooftop Solar Programme. However, subsidies are generally applicable for residential systems up to 10kW.

For commercial and industrial setups, subsidies are usually not available, but tax incentives and accelerated depreciation benefits can be claimed.

1. For Residential Users (Up to 10kW):

Under the PM Surya Ghar Muft Bijli Yojana, homeowners can get:

• ₹30,000 per kW for systems up to 2 kW
• ₹18,000 per kW for additional capacity (from 2 kW to 3 kW)
• Maximum subsidy: ₹78,000 for 3 kW
  
  

For larger systems like 30kW solar panels, residential subsidies typically do not apply.

2. For Commercial/Industrial Users:

While there’s no direct subsidy, users can benefit from:

• 40% Accelerated Depreciation on investment
• GST input credit
• Reduced electricity expenses
• Net metering benefits
  
  

This makes a 30kW solar system a financially smart investment for long-term energy cost reduction.
