The type of solar panels and inverters you choose, as well as the brand reputation, are critical factors that affect the solar system installation cost in India. For example, high-efficiency half-cut solar panels made with TOPCon or PERC technology tend to cost more than polycrystalline solar panels. But they’re still preferred because, when compared to almost-obsolete poly panels, they generate more electricity, perform better under shade and at high temperatures, and offer higher solar savings over 25 years. 

In this blog, we’ve explained the cost of installing rooftop solar panel systems for homes, conditions to avail a solar subsidy, and the benefits of on-grid over off-grid solar systems. We’ve also provided a detailed breakdown of the solar panel price per watt for homes, housing societies, and commercial complexes, explaining the factors that affect the cost and the myths you shouldn’t pay heed to when purchasing solar panels.

Top Factors that Affect the Solar Cell Price in India

The price of a solar panel system in India varies significantly depending on factors such as the type of panel and inverter you choose, brand reputation, manufacturing quality, and even warranty. 

Here’s a detailed breakdown of the multiple factors that influence the overall cost of solar installation in India:

• Component availability and market prices: Prices for panels, steel, silicon used to make solar cells, inverters, and copper wiring fluctuate based on global supply chains, foreign exchange rates, and import duties. When the cost of components changes, it is reflected in the final price of the solar system installation, too.
• The type of solar panel you choose: High-efficiency mono PERC, TOPcon, or bifacial panels cost more than basic polycrystalline panels, which are almost obsolete in India. But they also produce more power from the same space, making them worth the investment.
• Brand reputation: High-quality modules from premium solar panel manufacturers cost more because reputed brands ensure they use the highest quality products. They also test their panels rigorously to ensure optimal performance throughout the panel’s life. This increases manufacturing and testing costs, which, in turn, raise installation costs. However, these panels prove cost-effective in the long run, as they generate more power, resulting in higher savings.
• Warranty and longevity coverage: Longer product and performance warranties from top brands cost more upfront but provide better value and reduced risk over the long term.
• Size of the solar system: A larger system means more panels, wiring, inverters, and structure. So, the final cost increases with size, but the per-watt cost reduces.  
• Inverter technology: String inverters are up to 90% cheaper and widely used. Microinverters are more expensive and should be used only if nearby objects shade your rooftop during peak sunshine hours. 
• Structure height and custom design: If your system needs a taller mount to avoid shade, that will increase the cost. More height means more steel and more labor, which increases the cost of installing the system.
• Your roof and site conditions: Flat RCC roofs are easier and cheaper to install on. If your roof is uneven, sloped, shaded, or fragile, it may need special structures and safety gear.
• City and DISCOM-related charges: Application, inspection, and net metering fees vary across DISCOMs. Local labor rates and logistics also lead to small price differences across cities.
• Subsidy eligibility: If you’re eligible for the PM Surya Ghar Muft Bijli Yojana, the government will cover a part of your cost. That brings down the price sharply.
• Type of solar system: On-grid photovoltaic systems are the most affordable options. Off-grid and hybrid solar systems require lithium batteries, which are expensive and need to be replaced every few years.
• AMC (Annual Maintenance Contract): Opting for a full-service AMC will cost more upfront but protects your system over time. It covers things like inverter health checks, solar panel cleaning, and service visits.

*Please note: The above-mentioned solar panel price in Pune for on-grid solar systems listed is indicative as of 29th October 2025 for the SolarSquare Blue 6ft variant. The final solar plate price depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change. Additionally, when calculating savings, we have considered an annual tariff escalation of 3% and an annual plant degradation rate of 1%. The actual final savings from an on-grid rooftop solar system depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

On-Grid vs Off-Grid Solar Systems: Which is a Better Investment for Homeowners?

On-grid solar systems are preferred for residential installations because they do not require lithium batteries to store solar energy. Lithium batteries are expensive, and because on-grid systems do not need them, they’re a lot less expensive than off-grid solar systems.

On-grid systems are connected to the main utility grid:

• When panels generate more power during the day, excess energy is sent to the grid.
• At night, the system draws energy from the grid to keep your appliances running.

Here are the key differences between on-grid and off-grid solar systems that make it abundantly clear why on-grid systems are a better investment:
