500 Watt Solar Panel Price in India in 2025

Gone are the days when residential solar was stuck with standard 330-watt solar modules that had lower power generation capacity. The advent of 500-watt solar panels like SolarSquare’s 545-watt MonoPERC half-cut bifacial panels has changed the face of power generation by on-grid solar systems at homes. Naturally, what comes to mind next is whether or not the 500-watt solar panel price is still affordable. And the good news is, yes!

But before we can walk you through the ins and outs of the 500-watt solar panel price in India, you must understand that a solar panel alone doesn’t make the entire solar system. When you install solar at home (no matter which module size or type you choose), you’re paying the price for the entire system, not just the panels.  

With that established, the next question is how much a 500-watt single solar panel costs. The cost varies depending on the type of panel in question.

For demonstration purposes, let’s take into account two types here: polycrystalline and monocrystalline modules:

• 500-watt solar panel price for monocrystalline DCR modules in subsidy projects: Rs. 13,500* to Rs. 16,500*
• 500-watt solar panel price for bifacial modules: Rs. 12,000*

*Please note: The 500-watt solar panel price listed above is not fixed. The prices vary from city to city. Moreover, a 500-watt single solar panel cannot make a solar system. You would still require two solar panels of 500 watts each to make a 1 kW solar system.

In this blog, we will walk you through the detailed 500-watt solar panel specifications, prices and the factors that influence those prices, whether or not you get a subsidy for installing a 500-watt solar panel, and a detailed explanation on how to find out the ideal solar system size for your home based on your annual electricity consumption, and more. Let’s begin!

500-watt Solar Panel Price in India and Subsidy Details

Did you know? A solar system combines many components, including solar panels, mounting structures, AC and DC cables and combiner boxes, solar accessories, and a solar inverter. All these components work in tandem to generate electricity from sunlight, which then powers your home.

Solar panels are the most visible component of the system. They capture sunlight and convert it to electricity.  

Earlier, most residential installations used 330-watt solar panels (modules). Using 500-watt solar panels has become the new normal in residential solar. And the final price for solar installation in India heavily depends upon the type of panel technology you pick. The higher the panel efficiency, the higher the cost.

Before we talk about the prices, you must also know that there are four major types of 500-watt solar panels: Monocrystalline, Polycrystalline, Bifacial, and MonoPERC half-cut Bifacial. Let’s look into all of these in detail. 

• Monocrystalline 500-Watt Solar Panels: As the name suggests, this type of solar panel is made of mono-silicon cells. It offers a staggering efficiency of 19% to 20%.  
• Polycrystalline 500-Watt Solar Panels: The second type, polycrystalline solar panels, are cheaper than monocrystalline panels. They are made of multi-crystalline cells and have an efficiency of about 16% to 17%. 
• Bifacial 500-Watt Solar Panels: Unlike the other two, this solar panel has mono cells attached to both sides. Therefore, it is more efficient and provides up to 22% energy output. For this reason, a 500-watt solar panel price for the bifacial type is higher.
• MonoPERC 500-Watt Half-cut Bifacial Solar Panels: These are the latest types that use a blend of many technologies to increase efficiency. They are made of monocrystalline silicon, using the PERC technology. They’re the most efficient type of modules out of the four types. Their efficiency rate can shoot up to 22.5%.  

Now that you know the four major types, let’s also break down their prices:

• 500-watt solar panel price for DCR monocrystalline modules in subsidy projects: Rs. 13,500* to Rs. 16,500*
• 500-watt solar panel price for MonoPERC half-cut bifacial modules: Rs. 12,000*

*Please note: The 500-watt solar panel price listed above is not fixed. The prices vary from city to city. Moreover, a 500-watt single solar panel cannot make a solar system. You would still require two solar panels of 500 watts each to make a 1 kW solar system.

➡️ In fact, if you plan to install an off-grid or hybrid solar system, you’ll also have to keep in mind the nominal system voltage when purchasing. Whether you plan to have a 12-volt or a 24-volt battery bank must be considered. In general, the 500-watt 12-volt solar panel price in India is cheaper than the 500-watt 24-volt solar panel price in India. 

Do You Get a Solar Subsidy to Install 500-watt Solar Panels?

To set the record straight from the very beginning, let’s make this clear: the Indian government does offer a subsidy, but it starts from 1 kW solar systems only. Which means, if you install a system with just a single 500-watt solar panel:

• You will not get a subsidy
• The system will not be practical since a single 500-watt solar panel cannot generate enough electricity to keep an average Indian household running

Having said that, when you use 500-watt solar panels to install higher capacity solar systems, you automatically qualify for a subsidy (provided, you meet the eligibility criteria, which we have discussed in a later section).

Here’s a glimpse of how much solar subsidy is provided to homeowners under the PM Surya Ghar Muft Bijli Yojana:

• Subsidy for 1-2 kW solar system: Rs. 30,000 per kilowatt
• Subsidy for additional capacity till 3 kW: Rs. 18,000
• Subsidy for 3 kW or higher: Rs. 78,000

Did you know? The UP government offers an additional subsidy to the city residents on top of the subsidy offered by the central government. These are the state subsidy details: 1-2 kW systems: Rs. 15,000 per kilowatt Subsidy capped at: Rs. 30,000 So, for instance, if you are installing a 2 kW solar system in UP, the total subsidy you get will be Rs. 60,000 (central subsidy) + state subsidy (Rs. 30,000) = Rs. 90,000.

Based on the metrics above, here’s a simplified table for how much solar subsidy you can avail for systems of different capacities:

Solar System Size	Solar Subsidy for All States Except UP	Solar Subsidy for UP Residents
1 kW	Rs. 30,000	Rs. 30,000 + Rs. 15,000 = Rs. 45,000
2 kW	Rs. 60,000	Rs. 60,000 + Rs. 30,000 = Rs. 90,000
3 kW	Rs. 78,000	Rs. 78,000 + Rs. 30,000 = Rs. 1,08,000
3 kW	Rs. 78,000	Rs. 78,000 + Rs. 30,000 = Rs. 1,08,000
10 kW	Rs. 78,000	Rs. 78,000 + Rs. 30,000 = Rs. 1,08,000

Eligibility Criteria to Get a Subsidy Under the PM Surya Ghar Muft Bijli Yojana

The Indian government has pledged to solarize 1 crore Indian homes under the PM Surya Ghar Muft Bijli Yojana. And offering a subsidy is the government’s way to make solar affordable and more popular. However, this comes with an expiration date. The subsidy will only be offered till March 31, 2026.

Here are some simple conditions to avail a subsidy. If you fit this checklist, you, too, can take the help of the financial assistance being offered by the government:

• You must be an Indian citizen
• You must own a home with a rooftop
• You must install ALMM-approved, made-in-India DCR modules only
• You have never previously availed a solar subsidy

500-watt Solar Panel Specifications

Using a 500-watt solar panel is better than using standard 330-watt solar modules for the following reasons:

• You need fewer panels to design the desired system capacity
• Lesser rooftop space will be required
• Less installation hardware will reduce the installation cost

That said, here are some fascinating 500-watt solar panel specifications you must know:

• 500-watt solar panel dimensions: The 500-watt solar panel size is 6.41 feet in length and 4.20 feet in width.
• 500-watt solar panel warranty for manufacturing defects: 2 to 5 years

How Many 500-watt Solar Panels Do You Need to Make a System of Desired Capacity?

Let’s first talk about how to find the right system size for your home. The process is pretty straightforward.

Here’s what you need to do:

• Review your electricity bills from last year 
• Calculate the average number of units consumed in a year
• Divide your home’s yearly energy consumption by the number of units produced by a 1 kW solar system (1,400* units/year).

*On average, a 1 kW solar system produces 1,400-1,450 units per year.

Here’s what the ideal solar system size looks like based on the calculation tactics listed above:

Yearly Energy Consumption	Ideal Solar System Capacity for Your Home
1,400-1,450 units	1 kW solar system
2,800-2,900 units	2 kW solar system
4,200-4,350 units	3 kW solar system
7,000-7,250 units	5 kW solar system
14,000-14,500 units	10 kW solar system

Now that you know what system size would be ideal for your home, let’s calculate the number of 500-watt solar panels needed to build that system.

Number of 500-Watt Panels Required to Build a Desired System Capacity

Let’s assume you want to install a 2 KW solar system, and you want to know the number of solar panels you need. 

Here’s how it can be done: divide the solar system’s capacity by the solar panel’s capacity. 

In this case, 2,000 watts/500 watts = 4.

Hence, you would require four 500-watt solar panels for a 2 KW solar system. 

Based on the calculation formula above, here’s a tabulated snapshot of the number of 500-watt solar panels needed to design different capacity solar systems:

Solar System Size	Calculation Based on Formula	Number of 500-watt Solar Panels Required
1 kW	1,000 watts/ 500 watts	2
2 kW	2,000 watts/ 500 watts	4
3 kW	3,000 watts/ 500 watts	6
5 kW	4,000 watts/ 500 watts	8
10 kW	5,000 watts/ 500 watts	10
