Introduction
Thinking about installing solar panels at home in 2025? You’re not alone! With power bills rising and the government offering attractive subsidies, thousands of Indian homeowners are switching to solar.
This guide will walk you through everything you need to know — from installation costs to savings, subsidies, and whether it’s worth doing it yourself or hiring a pro.
Key Components of a Solar System
Before we get into the numbers, let’s break down what you’re actually paying for:
- Solar Panels: The heart of the system, capturing sunlight.
- Inverter: Converts DC electricity from the panels into usable AC power.
- Mounting Structure: Holds the panels in place, typically on your rooftop.
- Wiring & Connectors: Transfers power throughout the system.
- Installation Charges: Labor, scaffolding, and setup fees.
Types of Solar Systems
Grid-Tied System
- Connected to the local electricity grid
- Great for homes with consistent power supply
- Cheaper and eligible for net metering
Off-Grid System
- Works independently of the grid
- Includes battery storage
- Useful in rural or power-deficient areas
Hybrid System
- Combines grid connection with battery storage
- Offers flexibility and backup power
- Higher upfront cost but more control
