With Haryana emerging as one of India’s fastest-growing solar hubs, the demand for large-scale solar power plants has skyrocketed. A 500 kW solar power plant is ideal for factories, educational institutions, corporate parks, group housing societies, and hospitals that have high daytime power consumption.

At Smart Roof Solar, we specialize in engineering and installing such systems, offering complete transparency in solar installation charges, helping clients make the most of government solar subsidy schemes, and ensuring the total cost of solar installation remains economical and efficient.

What Is a 500 kW Solar Power Plant?

A 500 kW solar power plant can generate 6-7.5 lakh units of solar electricity per year, depending on sunlight availability and site layout. Given Haryana’s high solar radiation, this capacity provides excellent energy savings and quick returns.

This system size is perfect for:

• Large manufacturing units and industrial estates

• Commercial buildings and educational institutions

• Corporate parks and multi-story office complexes

• Housing societies with shared power requirements

Such a plant drastically reduces dependency on grid power, ensuring your facility enjoys reliable, clean, and renewable solar energy all year round.

Price & Cost Breakdown of 500 kW Solar Power Plant in Haryana (2025)

Typically, a 500 kW solar system in Haryana costs around ₹36,000 – ₹48,000 per kW, depending on material quality and site conditions. That brings your overall solar energy installation cost close to ₹1.8 – ₹2.4 crore for a complete turnkey solution.

Once installed, your effective cost of solar per kWh installed falls below ₹3 over the system’s lifespan, far cheaper than grid tariffs.

Power Generation, Payback & Savings

The payback period generally ranges from 3.5 to 4.5 years, after which the electricity generated is almost free. Over a 25-year lifetime, you’ll continue to save tens of lakhs annually, making solar one of the smartest long-term investments for any business. 

By opting for efficient panels and reliable components, your solar installation cost per kWh drops further, maximizing ROI. Refer to our blog – Solar Panel Payback Period Guide – Smart Roof Solar to know more.

Subsidy & Incentives in Haryana (2025)

PM Surya Ghar: Muft Bijli Yojana (Central Subsidy)

The PM Surya Ghar Scheme, launched in 2024, aims to make rooftop solar affordable for Indian households.

While commercial 500 kW systems don’t fall under this scheme, here’s how it works for smaller setups:

• ₹30,000 per kW for the first 2 kW

• ₹18,000 per kW for the next 1 kW (up to 3 kW total)

• Maximum subsidy capped at ₹78,000
  
  
• Applicable only for residential rooftop consumers.

State-Level Incentives (HAREDA & DISCOMs)

The Haryana Renewable Energy Development Agency (HAREDA) offers additional benefits under the state policy:

• Simplified net metering approval up to 500 kW (as per HERC regulation).

• Exemption from electricity duty and wheeling charges for captive use.

• Encouragement for Group Housing Societies (GHS) and Resident Welfare Associations (RWA) to install shared solar plants.

• Generation-Based Incentive (GBI) discussions for community rooftop and institutional projects (subject to new 2025 guidelines).

Although large C&I setups like a 500 kW solar plant do not directly qualify for subsidies, they gain a massive financial advantage through tax savings, depreciation benefits, and lower operational costs, ensuring that making solar energy economical remains achievable for every sector.

Factors Affecting Cost & Efficiency

Solar panel quality

Premium modules with higher efficiency reduce solar panel area per kW and maximize generation.

Roof or land condition

Structural reinforcement adds to the solar roof installation cost.

Cable quality and length

Impacts voltage drop and long-term reliability.

O&M & monitoring 

Timely maintenance reduces downtime and protects your investment.

Net metering approvals

Compliance with HERC norms ensures billing and credit accuracy.

At Smart Roof Solar, we help you plan every detail, from technical layout to approvals, so you know exactly how your solar panel system costs break down.
