25 MW Solar System Farms in India

High-capacity Solar systems of over 100kW are called Solar Power Stations, Solar Farms, Energy Generating Stations, or Ground Mounted Solar Power Plants. A 25MW solar power plant can run a commercial establishment independently from the Electricity grid. This size of solar farms takes up 124 to 125 acres of space and gives about 100000 kWh of low-cost electricity every day. Surplus power can subsequently be sold to the Electricity DISCOMs as per net metering mechanism of respective state government.

Cost & Specifications of 25 Megawatt Solar Power Plant

On average, the cost of a 25 MW solar power plant in India ranges between Rs 124 to 125 crores. Several factors influence the initial solar investment.

The key component making up a solar power plant is the solar panel which comes in various forms. Crystalline solar panels (monocrystalline and polycrystalline) are commonly used in most solar energy frameworks.

The monocrystalline version comes with a higher efficiency rating and thus increases the cost of your solar power plant in India.

Similarly, there are many other considerations that a consumer is required to make to put together the most suitable solar plant for their business.

Various Types of 25Megawatt Solar Power Plants

There are three types of solar plants that work on the same principle of ‘Photovoltaic Effect’. Each type of solar framework requires a different combination of solar components and thus determines your 25MW solar power plant cost in India. Your location, monthly energy requirements, and availability of space determine which of the following types of systems suit you best and give you maximum returns on your solar investment.

  • On-grid 50kW solar system (regulated under the net metering mechanism)
  • Off-grid 50kW solar system (suitable for remote locations)
  • Hybrid 50kW solar system (connects to the grid and also includes solar batteries)
Specifications of 25MW On-grid Solar Power Plant

In an on-grid framework, the cost of your 25MW solar plant is the lowest among all types of solar plants because solar panels and solar inverters are the only key components you need to set up an on-grid plant. On-grid means your 25MW solar power plant is connected to the government grid and regulated under the net metering mechanism.

Net metering facilitation (Based on respective state government guidelines and rules) allows your solar panels to sell unused solar power units to the utility company and receive solar credits. This becomes a type of passive income on your 25MW solar power plant. Likewise, you can withdraw grid power when your solar panels’ generation capacity falls below the standard.

Specifications of 25MW Off-grid Solar Power Plant

An off-grid framework works like an independent solar power station. It supplies free electricity to power your factory, manufacturing units, business and stores the surplus energy for later use. In addition to solar panels and the solar inverter, a solar battery bank is required to capture unused power units and create an invaluable energy reserve on-site for your business.

The inclusion of solar batteries increases the 25MW solar power plant cost, although the advantages still outweigh the cost. With the reliance on solar batteries, your business can thrive in remote locations where grid accessibility is costly or unavailable. By eliminating your dependence on the government grid, you also eliminate your electricity bills.

25MW Hybrid Solar Power Plant Specifications

A hybrid framework is the best way to discover your location’s true solar potential and reap this green technology’s maximum advantages. This type of solar plant combines the best of both on-grid and off-grid plants. Your hybrid solar plant has net metering advantages and also the reliability of solar batteries.

As a result, this type of 25MW solar power plant can help you achieve absolute energy independence and also ensure a 24-hour supply of electricity, meaning no downtime for your business

Types of Investment Models

If you are looking to get a 25MW solar power plant for your Manufacturing units, business or industry, you can choose to invest in your plant through either of the two models.

  • CAPEX Model (One-Time Investment)
  • OPEX or PPA Model
CAPEX Model (One-Time Investment)

In the CAPEX or one-time investment model, the consumer chooses to make an upfront capital expenditure. As you settle the entire cost of the 25MW solar power plant with your solar energy company, you become the owner of your solar plant and all the energy it generates.

As a solar power owner, you benefit from the supply of free-of-cost, clean electricity for the next 25+ years. This type of investment model is more suitable for purchasing systems of 100kW or less capacity for commercial or residential use.

OPEX or PPA Model

The cost of a 25MW solar power plant in India in 2024 can be overwhelming for many commercial establishments. However, an easy way to switch to solar and get a high-capacity plant is through third-party financing options. In this model, you’ll only have to bear the operational expenditure of your solar power plant and enjoy its benefits.

A solar energy company installs your solar plant at zero cost for a Power Purchase Agreement (PPA) of 10-25 years. After the installation of your solar plant, you pay a per-unit price every month at a rate lesser than the grid tariff. The PPA rates depend on the PPA period, installation land, and your credit rating. Simply put, a PPA agreement allows you to buy your electricity from a different supplier at a much lower rate.

Instead of signing a PPA agreement, you can consider taking a bank loan for your 25MW solar power plant in India. This financing option doesn’t rip you off of your solar ownership perks.

Income From 25MW Solar Power Plant

Many factors affect the income from your 25MW solar power plant. These include annual power consumption, the daily energy output of your solar panels, and the purchase policies and prices offered by the government. This income or return on the solar investment eventually helps you recover the initial cost within 6-8 years – called the average payback period.

Frequently Asked Questions About 25MW Solar Power Plant

How much area is required for a 25MW solar plant?

On average, a 1kW solar system requires a shade-free area of 6 square meters. Accordingly, to set up solar panels of 25mw, you need over 6000 square meters of land. The number of solar panels required and the mounting structure also affect the total 25MW solar power plant area required for installation.

Which financing model is more advantageous: OPEX or CAPEX?

Both models have their own set of pros and cons. If your business can make the required capital expenditure, you can easily become a solar owner. On the other hand, if you don’t have the flexibility of paying a heavy amount in one go, you can consider signing the PPA agreement under the CAPEX model. This way you pay a much lesser per-unit tariff rate on a monthly basis for a period of 10-25 years.

Is it difficult to operate and maintain a big power plant of 25-megawatt capacity?

Operating and maintaining your 25MW solar power plant is easier than you think. Solar panels require a basic cleaning routine and use a simple cleaning kit. Keeping your solar panels’ surface free of any accumulation is important to maintain their efficiency levels.

How many solar panels Array make up a 25MW solar power plant?

Determining the number of solar panels / Array your solar plant requires is important to figure out the 1-acre solar farm cost in India and the area required to install it. If you go for high-quality solar panels of around 400 watts each, your solar plant will require approximately 2500 panels.

How long do solar panels last?

Solar PV modules are the main component in all types and sizes of solar power plants. Most manufacturers provide a performance warranty of 25 years. In most cases, these solar panels continue to generate power for post the warranty period, however, at a reduced capacity level.
