Solar energy systems rely on a vital component - silicon wafers - that convert sunlight into electricity. These semiconducting wafers liberate electrons when exposed to sunlight, establishing a flow of direct current (DC) electricity. This efficient process allows solar systems to harness renewable energy from the sun, providing a sustainable power source
A grid-connected solar rooftop system does not produce electricity during a grid outage. However, battery-based systems don't just provide backup but also help generate electricity using solar during grid outages. Please refer to our products section to know more in detail
No, solar electricity is not wasted if it's not being consumed by the premises. During daytime, the solar system exports any excess electricity not used to the national electricity grid. Similarly, at night, excess electricity required by the premises is imported from the grid as solar generation is absent at night
Meter(s) installed along with the solar system keep a record of excess generation exported to the grid and imported from it. At the end of each period, customers are credited for excess generation exported to the grid as per the prevailing state policy, and charged only for net consumption from the grid
A photovoltaic (PV) system converts sunlight into electricity with the help of solar panels. These panels capture sunlight and create a flow of electrons to generate direct current (DC) electricity. This DC electricity is converted to alternating current (AC) by sending it to an inverter, making it suitable to power household appliances. The AC electricity flows through an electrical panel to power your home or business, while the excess energy is either sent back to the grid or stored in batteries for later use
The capacity of a solar connection installation depends on several factors:
1. Load requirement: The capacity needed to power your desired load through solar energy. This varies from state to state. On average, a 1 kW system is suitable for a monthly electricity bill of approximately Rs. 1,000
2. Shadow-free space availability: The amount of unobstructed space required for the installation. As a rule of thumb, a 1 kW system typically needs around 100 sq ft of shadow-free space
3. Sanctioned load: The maximum capacity allowed by state regulations. Generally, exceeding the sanctioned load capacity is not permitted
Solar energy is the power we harness from the sun’s radiation, converted into electricity or heat using technologies like photovoltaic panels or solar thermal collectors. In a solar photovoltaic system, panels made of semiconductor cells turn sunlight into electric current, while solar thermal systems capture heat. By installing a simple solar panel system on your roof, you can access this renewable, abundant energy, lower your electricity bills, reduce reliance on fossil fuels, and help cut greenhouse gas emissions.
The different types of solar panels in India are monocrystalline, polycrystalline, and thin film. Monocrystalline panels use one solid silicon crystal that gives smooth looks and strong output. Polycrystalline panels are made from blended crystals, so they are more affordable but slightly less efficient. Thin film panels have a thin active layer on glass or metal, making them lighter and flexible though they give lower power per area. For many homes, monocrystalline units rank among the best solar panels.
Solar energy works by converting sunlight into usable and reliable electricity. It converts sunlight into power through four technologies. Photovoltaic systems use semiconductor panels to generate electricity, which inverters refine into alternating current. On-grid solar systems feed surplus energy into the grid for credit via net metering and draw from it when panels produce less energy. Off-grid solar systems pair panels with battery storage to ensure uninterrupted power in remote, cloudy conditions. Solar thermal systems capture sunlight as heat to warm water or air for residential heating or industrial processes.

Solar energy is a renewable source of energy that relies on the sun’s light and heat to generate energy. It taps photovoltaic panels to produce clean electricity and uses thermal collectors to capture warmth for heating water and spaces. Unlike fossil fuels, solar never depletes and emits no carbon pollutants during operation. With abundant daily sunlight and minimal environmental impact, solar energy provides a smart solution for homes, businesses, and communities.
The benefits of solar energy are:
Reduces electricity bills by allowing users to generate their own power
Promotes energy independence for homes and businesses
Provides a renewable and abundant power source that relies on free sunlight
Generates clean electricity with minimal greenhouse gas emissions
Improves air quality and supports environmental conservation
Requires low operating costs after installation
Offers flexible system sizes suitable for both rooftops and large-scale plants
Supports both on-grid and off-grid applications
Drives job creation and economic growth through the expanding solar industry
Benefits from government incentives and subsidies that reduce upfront costs
Solar energy faces several limitations, primarily due to its dependence on sunlight and the inability to generate power consistently throughout the day. The upfront cost for panels and installation can be high, even as prices slowly fall. Production depends on daylight and weather, so cloudy days and night hours reduce output. Solar panel systems also need adequate roof or land space, which can be scarce in dense areas. Panel efficiency faces physical limits despite ongoing improvements. Adding battery storage or backup systems is often necessary to ensure power at night or during extended cloudy spells, increasing investment
Solar energy can reduce electricity bills by letting homeowners generate their own power. This means they rely less on the grid, and if they produce more energy than they use, they might even get credits through net metering for the excess electricity fed back into the grid. Incorporating battery storage further saves by holding excess power for night or cloudy days. Together these features deliver long-term savings and financial certainty.
To choose ideal solar panels, first measure your roof area and assess daily sunlight, then match panel types accordingly. When space is tight, monocrystalline modules deliver higher watt output per square meter, resulting in high efficiency. Larger roofs can accommodate polycrystalline panels which cost less but offer slightly lower efficiency. Thin-film technology is lightweight and flexible yet requires more surface for equal power. Be sure to review efficiency figures, independent durability tests, and warranty terms from reputable manufacturers before making a final purchase.
Solar energy can be a great option for both homes and businesses as it offers long-term savings on electricity bills and is better for the environment too. But to get the most out of it, your system needs to be the right size and designed for your specific location. Things like the age and size of your roof, how much shade it gets, the direction it faces, how much sunlight your area receives, and your current electricity costs all play a big role in deciding whether solar is a good fit and how much you could save.
Net metering is a billing system that lets owners of a solar panel system earn credits for excess electricity sent to the utility grid. You benefit from net metering primarily by reducing your electricity bills, as the credits earned for surplus energy can offset electricity drawn from the grid when your power generation is low, such as at nighttime or on cloudy days. This arrangement lowers electricity costs, speeds up payback, and makes solar power solutions more appealing for homes and businesses.
Yes, several government subsidies are available in India for solar installations.
Pradhan Mantri Surya Ghar Muft Bijli Yojana: Homeowners can receive free electricity up to 300 units per month and a subsidy of up to ₹78,000 for installing solar panel systems up to 3 kW.
MNRE’s Grid Connected Rooftop Solar Programme: Domestic rooftop systems are eligible for Up to 40% subsidy for systems up to 3 kW, and 20% subsidy for systems with capacity between 3 and 10 kW.
PM-KUSUM Scheme: Farmers can avail up to 60% subsidy for the installation of solar-powered agricultural pumps under this scheme.
