Complete Rooftop Solar Installation Process (Step-by-Step Guide for Mumbai Homeowners & Businesses)

Understand How Rooftop Solar Installation Works from Consultation to Commissioning

Switching to rooftop solar is a smart financial and environmental decision. However, many homeowners and business owners hesitate because they are unsure about the installation process.

Questions like:

• How long does installation take?
• Is government approval required?
• What is net metering?
• Will installation damage the roof?

This guide explains the complete rooftop solar installation process step-by-step, helping you understand what to expect before investing in solar energy.

Step 1: Site Survey & Feasibility Assessment

The first step in rooftop solar installation is a detailed site inspection.

During the survey, professionals evaluate:

• Roof size and structure
• Sunlight exposure
• Shadow analysis
• Electricity consumption patterns

This helps determine the correct system size and expected energy generation.

Step 2: System Design & Proposal

Based on the site survey, the installer designs a customised solar solution.

This includes:

• System capacity (kW size)
• Panel layout design
• Inverter selection
• Estimated savings calculation
• Cost breakdown

A clear proposal ensures transparency before installation begins.

Step 3: Documentation & Approvals

For grid-connected systems in Mumbai and Maharashtra:

• Net metering application may be required
• Utility approvals must be processed
• Government subsidy documentation (if applicable)

An experienced solar EPC company handles these procedures smoothly.

Step 4: Mounting Structure Installation

After approvals:

• Mounting structures are installed securely on the rooftop
• Structures are aligned at proper tilt angles for maximum sunlight exposure

Proper structural work ensures durability and long system lifespan.

Step 5: Solar Panel & Inverter Installation

Next:

• Solar panels are fixed onto mounting structures
• Wiring and DC connections are completed
• Inverter installation connects solar energy to usable power

Safety and quality checks are performed at every stage.

Step 6: Net Meter Installation & Grid Connection

If net metering is applicable:

• Bi-directional meter installation
• Grid synchronization
• Final inspection by authorities

This allows surplus energy to be exported to the grid.

Step 7: Testing & Commissioning

Before handover:

• System testing
• Performance verification
• Safety checks
• Demonstration to the customer

Once completed, the system starts generating electricity immediately.

How Long Does Rooftop Solar Installation Take?

For most residential systems:

• Site survey: 1–2 days
• Approvals: varies depending on process
• Installation: 1–3 days

Overall timeline depends on system size and documentation speed.

Is Rooftop Solar Safe for My Property?

Yes. When installed properly:

• Roof integrity remains intact
• Structures are securely mounted
• Systems are weather-resistant
• Minimal maintenance required

Professional installation ensures safety and performance.
