Choosing a 100kW solar panel system is a great option for businesses of any size in India. Resident Welfare Associations (RWA) and Group Housing Societies (GHS) are also getting these systems at discounted prices. Going solar is a smart way to lower your costs and be more independent with your energy.
A solar panel is made up of many silicon solar cells. When the sunlight hits these panels, it interacts with the silicon and changes its electrical characteristics. To put it simply, the sunlight makes electrons in the cells move around, creating a flow of electricity in one direction. This power goes through a device called a solar inverter, which turns it into the kind of electricity we use in our homes (AC electricity).
To power a whole property, you need to strategically arrange multiple solar panels to make a 100kW solar system.
Setting up a 100kW solar system can cost between Rs.30 lakhs and Rs. 55 lakhs upfront. The final cost depends on the quality of the parts and the type of system you choose for your business or home. Despite the initial cost, switching to solar has big advantages that far outweigh the upfront investment.
Businesses today face high costs, especially with the rising prices of electricity in the past ten years. This means you’re probably paying a lot for your monthly utility bills. Installing a 100kW solar system on your property can produce electricity for your daily needs at no extra cost. As you use less power from the grid, you’ll immediately notice a drop in your monthly utility expenses. In about 6-8 years, the money you save on electricity will cover the cost of the solar system.
Choosing solar power is not just about saving money; it’s also a good public relations move. Solar technology helps reduce greenhouse gases globally. By investing in solar, your business can improve its public image by showing that you care about the environment, are socially responsible, and embrace progress.
Think of the cost of a 100kW solar system as an investment to protect your business from future increases in electricity prices. Since it generates power for free, you can lock in a lower monthly electricity cost, removing the uncertainty that comes with grid-supplied power. This makes it easier for your business to plan for growth and the future.
The cost of a 100-kilowatt solar power plant in India ranges from Rs. 30 lakhs to Rs. 55 lakhs. To make the most out of your investment in solar energy and enjoy maximum savings and benefits, it’s a good idea to pick the best option. Let’s take a look at what you can anticipate when you decide to switch to solar power.
Model | 100kW Solar Price |
100kW On-grid solar system | Rs.35,00,000 |
100kW Off-grid solar system | Rs.40,00,000 |
100kW Hybrid solar system | Rs.50,00,000 |
| Key components | Solar panels, solar mounting structure, solar inverter, solar batteries (optional), the balance of system (cables, fuses, MCBs, and Distribution boxes) |
| Energy output | – 430 to 480 kWh of electricity per day – 14,400 kWh of electricity per month – 1,72,800 kWh of electricity per year |
| Area required | To install a 100kW solar system, you need a shade-free space of 600 Sq. Mtr. |
To get the most out of your solar power and save money, it’s important to choose the right size solar system for where you live, the space you have, and how much energy you use. These things help decide the kind of 100kW solar system that’s best for you and how many parts it needs. Let’s break down the different types of solar systems to help you make a smart choice.
On-Grid 100kW Solar Panel System (Works with Net Metering):
Off-Grid 100kW Solar Panel System (For Remote Locations):
Hybrid 100kW Solar Panel System (Grid-Connected with Batteries):
100 kilowatt Off grid solar system works independently without relying on the grid. It has solar batteries to store excess energy for later use. This way, you don’t depend on the grid, and you won’t have monthly utility bills.
Unused solar energy is stored in batteries. During the night or when solar energy is low, your property uses power from these batteries. This system is great for remote locations or areas with high electricity prices and frequent outages.
100 kilowatt Hybrid solar system combines features of both on-grid and off-grid systems. It includes net metering and solar batteries, making it a bit more expensive upfront. However, the higher initial cost pays off in the long run.
You save money on monthly electricity bills, and the solar batteries keep you powered during outages and at night. If you need extra energy beyond what the solar panels and batteries provide, you can still rely on the grid. The system stays connected to the grid and follows net metering guidelines for billing.

Solar energy is a renewable and clean source of power, reducing reliance on resources like water and coal. The Indian government is actively promoting solar power by incentivizing installations on residential rooftops, aiming to solarize 1 crore homes by 2024 with a budget of 5,000 Crore for rooftop solar projects. Challenges such as awareness, funding, rooftop availability, and financing options exist, but initiatives like subsidies and loans are being implemented to encourage adoption. Power distribution companies are also upgrading infrastructure to support increased solar capacity.
For rooftop solar plants installed for residential use all over India, the following Central Financial Assistance (CFA)/ Central Government Subsidy are available.
Rooftop Solar System Capacity | Applicable Subsidy (₹) |
Up to 3 kW | 14,588/kW |
Above 3 kW and up to 10 kW | 7,294/kW* |
Above 10 kW | 94,822** |
Note: *₹14,588/kW for the first 3 kW and ₹7,294/kW for the rest of the capacity up to 10 kW. **The subsidy amount is fixed for rooftop solar systems above 10 kW capacity. | |
| System | Benchmark Cost (₹/W) |
| 1kW | ₹51.10 |
| Above 1kW to 2kW | ₹46.98 |
| Above 2kW to 3kW | ₹45.76 |
| Above 3kW to Upto 10kW | ₹44.64 |
| Above 10kW and Upto 100kW | ₹41.64 |
| Above 100kW and Upto 500kW | ₹39.08 |
