What is solar energy and the implication of solar energy in your life!

Solar energy is a remarkable and sustainable source of power derived from the sun’s radiation through high efficiency solar panels. It plays a pivotal role in reducing our carbon footprint, mitigating climate change, and contributing to a cleaner and more sustainable future. Let us explore the fundamental workings of solar panels, the technology behind them, and the implications of solar energy in your life, with a particular focus on India’s solar industry.

How Solar Panels Work

Solar PV module are at the core of harnessing solar energy. These panels convert sunlight into electricity through the photovoltaic effect. Here’s how it works:

Photon Absorption: Sunlight contains photons, which are tiny packets of energy. The PV cells in the solar photovoltaic module are made of semiconducting materials like silicon. When photons strike the PV cells, they transfer their energy to the electrons in the cells, causing them to become excited.

Electron Movement: The excited electrons now flow through the material, creating an electric current. This flow of electrons is directed through an electrical circuit within the panel.

Electricity Generation: The movement of electrons results in the generation of direct current (DC) electricity. In most homes and industries, alternating current (AC) is used. To convert the DC electricity into AC, an inverter is typically employed.

Grid Connection: The converted AC electricity can be used to power your home, and any excess energy can be sent back to the grid, earning you credits or even financial compensation through net metering.

The Technology behind Solar Panels

The efficiency and lifespan of solar photovoltaic modules largely depend on the technology used. There are mainly two types of solar panels available:

Monocrystalline Solar Panels: These panels are made from a single crystal structure and are known for their high efficiency. Monocrystalline panels are more space-efficient and perform better in low light conditions.

Polycrystalline Solar Panels: These panels are made from multiple crystal structures, making them less efficient but more cost-effective. They are a good choice if you have ample space for installation.

Recent advancements in high efficiency solar panels, such as bifacial solar panel, Mono PERC modules and thin-film panels, have further improved efficiency and versatility of solar modules from Tier-1 solar manufacturers like Vikram Solar. Bifacial panels can capture sunlight from both sides, while thin-film panels are lightweight and can be integrated into various surfaces.

Efficiency and Lifespan of Solar Panels

Solar panel efficiency is an important factor in determining how effectively they can convert sunlight into electricity. Modern high quality solar panels from Tier-1 solar manufacturers like Vikram Solar have efficiencies ranging from 15% to 22%, depending on the type and manufacturer. High-efficiency panels capture more energy and require less space for installation.

The lifespan of high efficiency solar panels is impressive, typically ranging from 25 to 30 years or more. Most reputable manufacturers offer warranties that guarantee their performance for at least 25 years. Proper maintenance and cleaning can extend the panels’ life even further.

Implications of Solar Energy in Your Life

Reduced Electricity Bills: Residential solar panels provide a consistent source of electricity, which can significantly reduce your monthly utility bills, especially in sunny regions.

Environmental Benefits: Solar energy is clean and renewable, which means it reduces your carbon footprint and helps combat climate change.

Energy Independence: Solar panels empower homeowners to generate their own electricity, reducing dependence on centralized power grids

Government Subsidies and Incentives: Many governments, including India, offer subsidies and incentives to encourage the adoption of solar energy.

Solar Panels in India: Subsidies and Benefits

The Indian government has taken significant steps to promote solar energy adoption, including various subsidies and incentives. Some of the notable programs and benefits include:

Solar Subsidy Schemes: The Ministry of New and Renewable Energy (MNRE) offers subsidies for both residential and commercial solar installations. The extent of the subsidy varies depending on the type and size of the installation.

Net Metering: Many states in India have implemented net metering policies, allowing solar energy system owners to sell excess electricity back to the grid and earn credits or compensation. This is particularly beneficial for reducing electricity bills.

Tax Benefits: The government offers tax benefits and exemptions for solar photovoltaic module installations, including a reduction in property taxes and exemption from the Goods and Services Tax (GST) on solar equipment.

Low-Interest Loans: Financial institutions in India often provide low-interest loans for solar projects, making it more accessible for homeowners and businesses.


High quality solar panels and the technology behind solar panels have made significant strides in recent years. Efficient energy conversion, long lifespan, and environmental benefits of solar panels from Tier-1 solar manufacturers like Vikram Solar make them an attractive choice for homeowners and businesses. In India, government subsidies and incentives further encourage the adoption of solar energy, providing a cleaner and more sustainable future while reducing energy bills and promoting energy independence. Investing in PV module systems not only benefits your wallet but also the planet. It is time to harness the power of the sun for a brighter and more sustainable future.
