1. What Is Solar Energy?
Solar energy is electricity or usable energy generated from sunlight. In a photovoltaic solar system, solar panels convert sunlight into DC electricity, while an inverter converts that electricity into usable AC power for homes, offices and other applications.
If you are completely new to solar energy, start with our detailed educational guide:

Understanding the basics makes it easier to choose the correct system capacity, panel technology, inverter and installation configuration.
2. Rooftop Solar in India
Rooftop solar allows electricity consumers to generate power using the available roof area of a home, office, shop, factory or other building.
The correct system size depends on several factors, including electricity consumption, roof area, solar irradiation, shading, inverter configuration and the customer's energy requirements.

3. How to Choose the Right Solar System for Your Home
Before purchasing a solar system, homeowners should understand their monthly electricity consumption, available roof space, required capacity, inverter type, installation requirements, budget and applicable government rules.
Our dedicated guide explains the decision process:

4. On-Grid vs Off-Grid vs Hybrid Solar
One of the most important decisions is selecting the right system configuration.
- On-grid: Designed to operate with the electricity grid.
- Off-grid: Designed for locations where battery-backed independent operation is required.
- Hybrid: Combines solar generation with battery storage and grid interaction depending on system design.

11. Solar Installation: What Customers Should Check
A successful solar installation requires more than purchasing equipment. Customers should review system design, roof suitability, installation quality, safety, protection devices, documentation, warranties and applicable DISCOM or net-metering requirements.
- Check monthly electricity consumption.
- Check usable roof area.
- Review the proposed system capacity.
- Understand panel and inverter specifications.
- Review installation and balance-of-system components.
- Check warranty documentation.
- Understand applicable subsidy rules.
- Confirm the required grid and net-metering process.
12. Solar Business in India
India's expanding solar ecosystem creates opportunities for dealers, distributors, installers, EPC companies, sales professionals and technology providers.
A solar business can involve equipment trading, installation, lead generation, dealership, channel partnerships, project development or customer support.
