Electricity tariffs keep rising, and for most homes, shops and factories the monthly bill is a cost that never goes away. Rooftop solar changes that. Instead of buying every unit from the grid, you generate a large share of it on your own roof, from sunlight that costs nothing. This guide explains how it works and how to decide whether it makes sense for you.

How a rooftop solar system works

A solar system has four main parts. Solar panels turn sunlight into direct current (DC) electricity. An inverter converts it into the alternating current (AC) your appliances use. Mounting structures hold the panels securely on the roof, and a net meter records the electricity you use from the grid and the surplus you send back. During the day your home runs on solar power first, and the grid fills any gap at night or on cloudy days.

Where the savings come from

• Lower bills: every unit your panels generate is a unit you do not buy from the grid.
• Protection from tariff hikes: once installed, the cost of the power you generate stays fixed for the life of the system.
• Low running cost: there are no fuel costs and very few moving parts. Regular cleaning and a yearly check are usually all that is needed.
• Long life: good panels are typically warrantied for 25 years or more.

What decides the size of your system

The right system size depends on your average monthly electricity bill, the shadow-free roof area you have, and whether you want to cover all of your usage or only part of it. As a rough rule, a 1 kW system needs about 80 to 100 sq ft of shadow-free roof space. A site visit confirms the exact figures.

Solar for homes, businesses and industries

Every type of customer benefits, but in different ways:

• Residential solar reduces household bills and suits families who want long-term savings.
• Commercial solar cuts operating costs for shops, offices, schools and hospitals, which use most of their power in the daytime when solar produces the most.
• Industrial solar serves factories and warehouses with large roofs and heavy power use, where the savings are the biggest.

Government support

Central and state schemes, such as the PM Surya Ghar: Muft Bijli Yojana for eligible homes, can reduce the upfront cost of a residential system. Subsidy rules and amounts change from time to time, so always confirm the current terms before you apply. Our team can guide you through the paperwork.

Keep your system performing

Solar panels lose output when dust and dirt build up on them. A regular AMC panel cleaning service keeps generation high and protects your savings year after year.
