Factors Affecting the 50 kW Solar Panel System Price in India in 2025

On-grid solar systems are the most cost-effective because, unlike hybrid and off-grid solar systems, they do not require batteries. This reduces both the installation and maintenance costs. However, that’s not the only factor that affects the final price of a 50 kW solar panel system in India. Several other factors, such as the type of solar panels and inverter, roof height, and the height of the mounting structure, also impact the final price. 

Let’s check out all the important factors that influence the final 50 kW solar system installation cost in India:

• Type of solar system: On-grid systems are the most budget-friendly and don’t need batteries. However, if you opt for off-grid or hybrid solar energy systems, you’ll need lithium batteries, which are both expensive to install and maintain.
• Whether or not you’re eligible for a subsidy: If your society is eligible for the government subsidy, you’ll save a good amount on the total installation cost. 
• Type of solar panels: DCR solar panels are eligible for a subsidy, which reduces the overall system cost. Also, if you pick high-efficiency panels, you’ll pay more, but they’ll generate more power from the same amount of solar radiation.
• Type of solar inverter: MPPT inverters are a bit pricey, but they ensure your solar panels generate maximum power throughout the day. So, you’re spending more upfront for better performance and higher returns in the long run.
• DISCOM charges: Your local electricity provider (DISCOM) may charge extra based on the complexity of connecting your system to the grid.  
• Mounting structure height: Taller frames need more materials and skilled labor. Hence, the taller the structure, the costlier it is.
• Type of after-sales service: If you choose a plan that includes regular servicing or repairs, like an AMC, it’ll cost more upfront. But it can save you from surprise expenses later if something goes wrong with the solar system.
• Roof height: The higher your roof, the trickier it is for workers to carry materials and install everything. This adds to your final bill.
• Number of floors in your society: More floors mean longer wires to connect your rooftop system to the main meter. This makes the job more complex and increases both material and labor costs.

What Are the Types of a 50 kW Solar System in India?

The three primary types of 50 kW solar systems in India are on-grid, off-grid, and hybrid PV systems. On-grid solar systems are the most recommended options for homes, housing societies, and commercial or industrial buildings because they’re the most effective and have the highest and quickest ROI. 

• On-grid solar systems: They’re connected to the utility grid through a bi-directional net meter. The solar panels produce DC output during the daytime. The inverter converts this DC output to AC, which is supplied to your housing society. If there’s any surplus current generated, the net meter will transfer it to the grid. At night, the same net meter will import electricity from the grid to keep the load running.
• Off-grid solar systems: Instead of the grid, they’re connected to a lithium battery bank. The solar panels produce DC output, which the inverter converts to AC to keep the load running during the daytime. Surplus DC is used to charge lithium batteries through the built-in MPPT charge controller present in the solar inverter. This stored solar energy is used to keep the load running at night.
• Hybrid solar systems: They’re connected to both the grid and a lithium battery bank. The solar inverter converts a portion of DC power from panels to AC power and keeps loads running during the daytime. If there’s any extra current generated, it’s used to charge the batteries. If the batteries are full or more current remains after they’re charged, it’s sent to the grid through the bi-directional net meter. Stored energy in the batteries is used to keep the load running at night.

Here’s a tabulated snapshot of how the three types truly differ and why housing societies with a reliable grid connection benefit the most from an on-grid rooftop solar panel system:

Here’s the formula that we’ve used:

Based on this formula, let’s check out the precise calculation:

Ground-Mounted vs Rooftop Solar: Why’s Rooftop Solar Better for Housing Societies?

A rooftop solar system is better than ground-mounted solar systems because of the following reasons:

• It needs only unused rooftop space: Unlike ground-mounted solar systems, which need large areas of open land, a rooftop solar system can be set up on the unused, shadow-free area of your roof.
• It’s eligible for a subsidy: The Indian government offers a subsidy to housing societies only for installing on-grid rooftop solar systems, not ground-mounted systems.
• It’s cheaper: There’s no need to buy acres of land since rooftop solar systems are installed on rooftops. Moreover, the government subsidy further reduces the 50 kW solar panel system price in India. 

So, when to choose rooftop solar systems?

• When installing rooftop solar panel systems for homes
• When installing rooftop solar for housing societies
• When installing commercial and industrial rooftop solar panel systems

When to choose ground-mounted solar systems? If you’re installing utility-scale solar systems to produce gigawatts of electricity, ground-mounted systems are suitable options.
