1kW Solar System for Home | Complete Setup with Panels, Battery & Inverter Price in 2025

As energy costs rise and environmental concerns grow, many homeowners in India are turning to solar energy. A 1kW solar system is an excellent entry point for small households, offering a balance between affordability and energy independence. This guide provides a detailed breakdown of the components, costs, and benefits of installing a 1kW solar system in 2025.

Components of a 1kW Solar System

Solar Panels: Typically, a 1kW system requires 3 to 4 panels, each rated between 250W to 350W. These panels capture sunlight and convert it into direct current (DC) electricity.
Inverter: The inverter converts DC electricity from the panels into alternating current (AC) electricity, which is used by household appliances. For a 1kW system, a 1kW capacity inverter is suitable.
Battery (for Off-Grid or Hybrid Systems): Batteries store excess energy generated during the day for use at night or during power outages. Depending on the system design, you might use one or two batteries.
Mounting Structure: This framework supports the solar panels, ensuring they are securely positioned at the optimal angle for sunlight exposure.
Charge Controller: This device regulates the voltage and current coming from the solar panels to the battery, preventing overcharging and prolonging battery life.
Cabling and Connectors: Quality cables and connectors ensure efficient and safe transmission of electricity between components..

Types of 1kW Solar Systems

On-Grid System: Connected to the public electricity grid, this system allows you to feed excess power back to the grid, potentially earning credits. It doesn’t function during power outages unless paired with a battery.
Off-Grid System: Independent of the public grid, this system relies entirely on solar power and battery storage, making it ideal for remote areas without reliable grid access.
Hybrid System: Combines features of both on-grid and off-grid systems, offering grid connectivity and battery backup, ensuring power availability even during outages.

Cost Breakdown in India (2025)

The cost of a 1kW solar system varies based on the type:

On-Grid System: Approximately ₹80,000
Off-Grid System: Approximately ₹1,05,000
Hybrid System: Approximately ₹1,05,000

Government Subsidies

Under the Pradhan Mantri Surya Ghar Muft Bijli Yojana, eligible households can receive subsidies to reduce the upfront cost of solar installations. For a 1kW system, the subsidy can range from ₹30,000 to ₹60,000, depending on the state’s policy and the household’s electricity consumption.

Benefits of Installing a 1kW Solar System

Reduced Electricity Bills: Generate your own electricity and decrease dependence on the grid.
Environmental Impact: Solar energy is clean and renewable, reducing your carbon footprint.
Energy Independence: Especially with off-grid or hybrid systems, ensure power availability during outages.
Return on Investment: Over time, savings on electricity bills can offset the initial investment.

Conclusion

Investing in a 1kW solar system in 2025 is a smart choice for homeowners looking to reduce electricity costs and promote sustainable living. With government subsidies and advancements in solar technology, the transition to solar energy has become more accessible than ever.
