Understanding Solar Panel Technology
Solar panel technology harnesses the sun’s power to generate clean, renewable energy. At the core of a solar panel are photovoltaic (PV) cells, which convert sunlight into electricity. These cells are made primarily from silicon, a material known for its semi-conductive properties. When sunlight hits the PV cells, it excites electrons in the silicon, creating an electrical current. This process, known as the photovoltaic effect, is the foundation of solar energy production.
Manufacturers assemble multiple PV cells into panels to capture more sunlight and generate more electricity. In conjunction with an inverter, these panels convert the direct current (DC) electricity produced by the cells into alternating (AC) electricity, which can power homes and businesses. Modern solar systems can also include battery storage to retain excess energy generated during sunny periods for use at night or during overcast conditions, enhancing the efficiency and reliability of solar power.
Advancements in solar technology continue to improve efficiency rates and reduce manufacturing costs, making solar energy an increasingly competitive alternative to fossil fuels. With the potential to significantly reduce greenhouse gas emissions and combat climate change, solar panel technology represents a pivotal shift toward a more sustainable future. And as more individuals and organisations adopt solar energy, the demand for further innovation and development will only grow. This presents a promising opportunity for continued advancements in solar panel technology, paving the way for a cleaner, brighter future.
Types of Subsidies for Solar Installations
In India, two main types of subsidies are available for solar installations: capital subsidies and generation-based incentives (GBIs).
- Capital Subsidies
Capital subsidies involve the government’s one-time financial support to cover a portion of the capital investment required to set up solar power projects. This can include subsidies for purchasing solar panels, inverters, and other equipment required for installation.
- Generation-Based Incentives (GBIs)
Generation-based incentives are performance-based subsidies that provide financial support based on the electricity generated from solar installations. The higher the electricity generation, the higher the incentive.
- Feed-in Tariffs (FiTs)
Feed-in Tariffs are a type of subsidy designed to encourage the adoption of renewable energy through government guarantees. Under this scheme, individuals or companies who produce their electricity from solar installations are paid a premium for the electricity they supply to the grid over a fixed period. This ensures a secure and attractive return on investment for solar energy producers, thereby accelerating the installation of solar capacity.

How to Choose the Right Solar Panel System for Your Home
Understanding your energy needs is the first crucial step when considering a solar panel system for your home. Begin by reviewing your household’s electricity bills over the past year to get an average of how much energy you consume monthly. This insight will help you determine the size of the solar panel system required to meet your energy needs effectively. Additionally, evaluate the solar potential of your location; not all areas receive the same amount of sunlight.
Tools like the National Renewable Energy Laboratory’s PVWatts Calculator can estimate how much energy a solar panel system might generate based on your roof’s exposure and location. Also, examine the types of solar panels available—monocrystalline, polycrystalline, and thin-film—each offering different efficiencies, aesthetics, and price points to match your energy needs, budget, and home’s architecture.
Once you have a clear understanding of your energy consumption and solar potential, it’s time to consider the installation options that best suit your home. A rooftop system is the most common type of residential solar panel installation; however, if your roof isn’t suitable for solar panels due to shading or orientation issues, consider a ground-mounted system instead.
Ground-mounted systems are more flexible and can be positioned for maximum sunlight exposure. They also offer installing solar panels on a separate structure, such as a carport or shed, freeing up space on your roof. Another installation option is a solar pergola, which combines the benefits of a ground-mounted system with an aesthetically pleasing structure that can enhance your outdoor living space.
In addition to the installation type, you should consider the financing options for your solar panel system. Purchasing a solar panel system outright may require a significant upfront investment, but it offers the most long-term savings and control over your energy production. Alternatively, leasing or entering into a power purchase agreement (PPA) can reduce your initial costs; however, these options may limit your ability to claim government incentives and result in higher overall costs. Carefully weigh the pros and cons of each financing option, keeping in mind your current budget and future financial goals.
