The cost of installing a rooftop solar system can vary depending on several factors, including the capacity of the system, the quality of solar panels and other components, installation complexity etc. Prices may have changed since then due to market fluctuations and changes in government policies.
As mentioned earlier, for residential installations, the cost typically ranged starts from ₹60,000 per kilowatt (kW) installed capacity. Commercial and industrial installations may have different pricing structures.
Here's a general breakdown of costs for a rooftop solar system:
Solar Panels: The cost of solar panels depends on their capacity and efficiency. The cost of solar panels per kW could range from ₹20,000 to ₹30,000.
Inverter: The solar inverter is an essential component that converts DC power generated by the solar panels into usable AC power. The cost of inverters varies based on their capacity and type. For a typical residential system, the inverter cost could be around ₹10,000 to ₹20,000 per kW.
Mounting Structures: The cost of mounting structures depends on the type of roof and the complexity of the installation. On average, it could be around ₹5,000 to ₹10,000 per kW.
Balance of System (BOS): The balance of system components includes cables, connectors, junction boxes, and other accessories required for the system. This cost could be around ₹5,000 to ₹10,000 per kW.
Installation Charges: The installation cost covers the labour and expertise required to set up the system. It can vary depending on the size and complexity of the installation.
It's important to remember that prices can vary regionally, and the government subsidies, incentives, and policies in different states can significantly affect the overall cost of installing a rooftop solar system. I recommend reaching out to local solar installers or companies for the most up-to-date and accurate cost estimates for rooftop solar installations in your specific location. They can provide customized quotes based on your requirements and help you navigate any available incentives to reduce the upfront cost.
