Solar Panels: A 5kW off-grid solar system would require approximately 16-20 solar panels, depending on the wattage of the panels. The cost of the solar panels would vary depending on the quality and warranty, but an estimate would be around INR 1.2 lakh to INR 1.8 lakh.
Inverter and Charge Controller: An off-grid solar system requires an inverter and charge controller that converts the DC electricity generated by the solar panels into usable AC power. A 5kW off-grid solar system requires an inverter with a capacity of at least 5kW and a charge controller with a capacity of at least 60 Amps. The cost of the inverter and charge controller would be approximately INR 1.5 lakh to INR 2 lakh.
Batteries: Off-grid solar systems require batteries to store the excess energy generated by the solar panels for use during periods of low sunlight or at night. A 5kW off-grid solar system would require a battery bank with a capacity of at least 20kWh. The cost of the batteries would depend on the type and brand, but an estimate would be around INR 2.5 lakh to INR 3.5 lakh.
Mounting Structure and Cables: The solar panels need to be mounted on a sturdy and durable structure that can withstand harsh weather conditions. The mounting structure should be designed to suit the type of roof or ground mounting and should be installed by a professional. The cost of the mounting structure and cables would be approximately INR 1 lakh to INR 1.5 lakh.
Installation Charges: The installation charges for an off-grid solar system depend on the complexity of the installation, location, and labor charges. The installation charges for a 5kW off-grid solar system would be approximately INR 1 lakh to INR 1.5 lakh.
Therefore, the total cost of a 5kW off-grid solar system would be approximately INR 8 lakh to INR 11 lakh. It is important to note that these prices are estimates and may vary depending on the location, quality of components, and installation charges. It is recommended to get quotes from multiple vendors and compare prices before making a purchase.
