100kW Solar System Price – On grid, Off grid and
These costs can range from Rs. 50,00,000, depending on the brand of solar system you choose. Energy plays a very important role
Subsidy and ROI Calculations Included The 100 kW solar panel system price in India in 2025 for on-grid DCR subsidy projects ranges between ~Rs. 40,000* to ~Rs. 45,000* per kW + 13.8% GST, after you receive a subsidy.
Aside from the main solar components (solar panels and a solar inverter), the system is equipped with a net metering system to record the flow of power between the grid and your solar system. Due to fewer components, an on-grid 100kW solar system cost in India is the lowest among all the three types of solar systems.
Due to fewer components, an on-grid 100kW solar system cost in India is the lowest among all the three types of solar systems. During peak sun hours on sunny days, your solar panels are likely to generate a surplus. All the unused solar energy is fed to the grid in return for solar credits.
A 100 kW solar panel system, capable of generating 1.35 lakh* to 1.4 lakh* units of electricity annually, varies in cost based on whether it's an on-grid system without lithium batteries or an off-grid or hybrid system with batteries. *Please note: The number of units generated by a 100 kW solar panel system listed above is indicative.
