Key Components of a 3kW Solar System

  1. Solar Panels – The main component that captures sunlight and converts it into electricity.
  2. Inverter – Converts the DC power generated by panels into AC power for household use.
  3. Battery (Optional) – Stores excess electricity for later use (used in off-grid systems).
  4. Mounting Structure – Supports the panels and ensures proper orientation.
  5. Wiring & Other Accessories – Includes cables, junction boxes, and connectors for proper functioning.

  • Price Range: ₹1,50,000 – ₹1,80,000
  • Best For: Homes and businesses with a stable grid connection
  • Benefit: Can export extra power to the grid and reduce electricity bills

2. Off-Grid 3kW Solar System

  • Price Range: ₹1,80,000 – ₹2,20,000
  • Best For: Areas with frequent power cuts or no grid connection
  • Benefit: Works independently using batteries to store energy
