🌞 How to Install a Solar System at Your Home — Step-by-Step Guide

Introduction

Installing solar at home can feel complex — panels, inverters, wiring, subsidies, net metering — but when broken into clear steps, the process becomes simple and predictable.
This guide walks you through each stage so you know exactly what to expect before going solar in India.

✅ Step 1: Analyse Your Electricity Consumption

Check your past 12 months’ electricity bills.

Note the following:

• Monthly units (kWh)

• Highest month (peak consumption)

• Connected load

Common rule:
100 units/month ≈ 1 kW solar system.

✅ Step 2: Decide Your Solar Capacity

Based on consumption:

• 150–200 units/month → 2 kW

• 250–300 units/month → 3 kW

• 350–400 units/month → 4 kW

• 450–500 units/month → 5 kW

Your solar installer will confirm the exact size.

✅ Step 3: Choose the System Type

There are three major types:

1. Grid-Tied System

• No batteries

• Maximum savings

• Works with net metering
  Best for: Homes with stable grid supply

2. Hybrid System

• Solar + Grid + Battery

• Power at night + outage backup
  Best for: Homes needing 24×7 stable power

3. Off-Grid System

• Battery-dependent

• No grid needed
  Best for: Remote or low-grid areas

✅ Step 4: Roof Inspection & Site Survey

A technician will check:

• Roof direction & slope

• Shading (trees, buildings, water tanks)

• Available area

• Structural strength

• Distance to electrical panel

Minimum space required:
1 kW ≈ 80–100 sq ft

✅ Step 5: System Design & Quotation

The solar company prepares:

• Panel layout

• Inverter selection

• DC/AC wiring plan

• Safety components

• Savings & ROI estimate

Review:

• Warranty on panels (25 years)

• Warranty on inverter (5–10 years)

• Brand quality (Tier-1 recommended)

✅ Step 6: Apply for Subsidy (If Applicable)

For residential customers under PM Surya Ghar Yojana:

• Register on the national portal

• Choose empaneled vendor

• Upload documents

• Inspection → approval → subsidy disbursement

This step is usually assisted by your installer.

✅ Step 7: Installation & Commissioning

Installation is completed in 1–3 days.

Work includes:

• Mounting structure installation

• Panel fixing

• Inverter setup

• DC/AC wiring

• Earthing & lightning protection

• Testing & commissioning

✅ Step 8: Net Metering Approval

Your DISCOM installs:

• Net meter

• Bidirectional meter
  This allows exporting extra power to the grid.

Processing time varies by state (1–6 weeks).

✅ Step 9: Monitoring Setup

Your inverter app shows:

• Daily generation

• Monthly savings

• System health

• Alerts & faults

This helps ensure peak performance.

✅ Step 10: Maintenance (Very Minimal)

Solar systems need low upkeep:

• Clean panels every 15–30 days

• Check wiring yearly

• Monitor performance through app

That’s it — solar runs smoothly for 25+ years.

🌍 Final Thoughts

Installing a solar system at home is one of the smartest financial and environmental decisions you can make. With the right planning and the right installer, the process is simple, efficient, and highly rewarding.
