What Is Solar Rooftop Installation for Homes?

Solar rooftop installation involves placing solar panels on the roof of a residential building to generate electricity from sunlight. The generated power is used for household consumption, and any excess electricity can be exported to the grid through net metering.

A typical residential solar system includes:

• Solar panels
• Solar inverter
• Mounting structure
• DC and AC cables
• Net meter

Solar Rooftop Installation Process (Step-by-Step)

1. Site Survey & Roof Analysis

• Available roof area
• Shadow-free space
• Roof orientation and tilt
• Structural strength

2. Load Calculation & System Design

Your electricity consumption is analyzed to determine the correct system size such as 1 kW, 3 kW, or 5 kW.

3. Structure & Panel Mounting

Mounting structures are securely fixed, and solar panels are installed at the optimal tilt angle for maximum energy generation.

4. Inverter Installation & Wiring

The inverter converts DC power into usable AC power, and all electrical connections are completed with proper safety protection.

5. Net Metering & Commissioning

After inspection and approvals, the net meter is installed and the system is commissioned.
