    Indian States Under Government Programs

    The PM Surya Ghar: Muft Bijli Yojana, aimed at making households energy-independent, has been criticized for imposing free electricity programs on rooftop solar, despite the government’s efforts to promote solar adoption.

    The PM Surya Ghar program, aimed at making households energy-independent, has been criticized for its lack of investment in rooftop solar systems in some states. Consumers receive up to 300 free units per month, making them reluctant to invest in such systems. Additionally, these programs put financial strain on power distribution companies, many of which are already struggling with debt. The Parliament’s standing committee on finance has warned that the ministry of new and renewable energy will face challenges in achieving the 2026 target of installing 3.5 million rooftop solar systems.

    Punjab

    Punjab, a state in India, provides 300 free electricity units per household, but this has reduced interest in rooftop solar adoption. Installers argue that consumers are often hesitant to invest in solar due to the lack of free power and the loss of their right to free units. Punjab’s billing system is also flawed, with frequent errors and unexpected charges causing frustration.

    The latest figures show a billing efficiency of only 89.27%. Stakeholders in Punjab are calling for awareness programs to educate consumers about the long-term savings of solar and a modification of the 300 free unit policy to offer a buyback system, allowing people to sell excess solar energy at a fair price. This would increase consumer interest in solar systems.

    Delhi

    Delhi offers 200 free electricity units per household, but many people believe it is entirely free up to a certain limit. This perception leads to a reluctance to install solar panels, as they believe they won’t get any additional financial benefit. During peak summer, households may consume around 350-400 units, exceeding the free limit, which can offset these additional charges.

    Customers often assume everything is covered under government programs, but they don’t realize they still need to pay an initial amount, including GST. This reluctance to invest is largely due to a focus on immediate expenses. Many rooftops in Delhi are not structurally suited for solar panel installations, and many customers are unaware of how to apply for government-backed solar loans. Increased awareness about the long-term benefits of solar energy, including cost savings and environmental impact, can help change perceptions and increase solar adoption.

    Jharkhand

    Jharkhand offers 200 free electricity units per household, but those within this limit see little incentive to invest in solar. Those with higher consumption levels are more likely to adopt solar to offset additional costs. The free units remain applicable even after installing a rooftop solar system under the PM Surya Ghar program, allowing consumers to reduce their electricity bills further. Many consumers in Jharkhand, especially in rural areas, are unaware of government programs like PM Surya Ghar that offer financial support for solar installations.

    Rural residents often struggle to navigate application processes for subsidies and loans, leading to abandonment or delay in installation. Simplifying the subsidy process and introducing community solar projects could improve adoption rates. Awareness campaigns tailored for rural areas are needed to bridge the knowledge gap and encourage wider participation in solar energy initiatives.

    Karnataka

    Karnataka installers argue that free electricity does not discourage rooftop solar adoption, as 90% of people are aware of government incentives and choose to go for solar regardless of free electricity programs. In cities like Bengaluru, educated and environmentally conscious individuals are motivated by sustainability and long-term savings on electricity bills. However, they suggest that providing additional subsidies on top of existing central subsidies could help encourage rooftop solar adoption.

    In Karnataka, residential consumers who already benefit from state-provided free electricity become ineligible for the free electricity program, making the state one of the laggards in rooftop solar adoption. The government should consider providing additional subsidies to encourage rooftop solar adoption.

    Tamil Nadu

    The Tamil Nadu free electricity program does not currently have regulations preventing customers from removing their names from the program if they opt for the PM Surya Ghar program. Customers benefit from both programs and receive a net-metering tariff for extra power sent to the grid. However, the free electricity program is preventing many people from switching to solar. Installers are urging consumers to be aware that the free electricity program is state-based and can be reduced or removed entirely. If a customer chooses rooftop solar under any program, including PM Surya Ghar, they will benefit for up to 25 years under a fixed tariff agreement with DISCOMs.

    Rajasthan

    Rajasthan’s industry sources argue that the government is not promoting rooftop solar, but rather shifting the burden of free electricity by leveraging subsidy benefits. The government recently announced 150 units of free monthly electricity for the Chief Minister Free Electricity Program beneficiaries, but no guidelines are in place for implementation. Ajay Yadav, President of Rajasthan Renewable Energy Association, suggests that the government should provide direct subsidies of ₹20,000 to ₹40,000 to encourage consumers to adopt solar.

    Free electricity programs have serious financial consequences for DISCOMS, which are heavily in debt. Unpaid or delayed government reimbursements for the loss of revenue from freebies push them into a debt trap, impeding their ability to invest in modernizing infrastructure and improving efficiency. The conflict between free electricity programs and solar adoption presents a key policy challenge, potentially slowing the uptake of solar under the PM Surya Ghar: Muft Bijli Yojana.

    The Impact of Free Electricity Programs on Solar Adoption

    ​Free electricity programs, designed to provide affordable energy access, can inadvertently hinder the adoption of rooftop solar installations. By reducing or eliminating monthly electricity expenses, these programs diminish the financial incentives for households to invest in solar energy systems. For instance, in regions like Rajasthan, industry sources have observed that offering 100 units of free electricity can negate the perceived need for a 1 kW rooftop solar system.

    To address this challenge, some governments are implementing targeted incentives to promote solar adoption among low-income households. In India, the PM Surya Ghar: Muft Bijli Yojana offers subsidies covering up to 40% of the installation cost for rooftop solar panels, aiming to make solar energy more accessible and financially viable. ​

    Additionally, community solar programs present an alternative approach by allowing multiple households, including renters and those without suitable rooftops, to benefit from shared solar installations. These programs can expand solar access to low-income families, renters, and multifamily building residents, thereby promoting renewable energy adoption without the need for individual installations.

    By integrating such targeted incentives and community-based solutions, it is possible to align free electricity initiatives with the goal of increasing rooftop solar adoption, ensuring that energy affordability and sustainability objectives are met concurrently.

    How to Overcome the Free Electricity Disincentive

    ​Free electricity programs, while aiming to provide affordable energy access, can inadvertently reduce the incentive for households to invest in rooftop solar installations. To counteract this effect and promote solar adoption, the following strategies can be implemented:​

    1. Implement Targeted Incentives

    Governments can offer additional financial incentives specifically designed to encourage rooftop solar adoption among households benefiting from free electricity programs.

    10 Benefits of Solar Cells You Need to Know

    Solar Cells

    In today’s world, where the demand for sustainable and renewable energy sources is at an all-time high, solar cells have emerged as a revolutionary technology. A solar cell, also known as a photovoltaic (PV) cell, converts sunlight directly into electricity, making it a crucial component of solar power generation. With advancements in solar technology, solar cells are becoming more efficient, affordable, and widely used in residential, commercial, and industrial applications.

    This blog explores the fundamentals of solar cells, their types, working principles, advantages, applications, efficiency, and prospects. If you are considering switching to solar energy, understanding solar cells is the first step toward a greener and more sustainable future.

    What is a Solar Cell?

    A solar cell, also known as a photovoltaic (PV) cell, is an electronic device that directly converts light energy into electrical energy through the photovoltaic effect. Composed primarily of semiconductor materials like silicon, solar cells are fundamental components in solar panels, enabling the harnessing of solar energy for various applications.

    The fundamental construction of solar cells is the same whether they are found in a calculator, a spacecraft, or a central power plant. An optical coating, also known as an antireflection layer, allows light to enter the device and reduces light loss due to reflection. This coating efficiently traps light that falls on the solar cell by encouraging its transfer to the layers below that convert energy. Usually created on the cell surface by spin-coating or vacuum deposition, the antireflection layer is an oxide of silicon, tantalum, or titanium.

    How Do Solar Cells Work?

    The working principle of a solar cell is based on the photovoltaic effect, which involves the following steps:

    1. Absorption of Sunlight

    • Solar cells are made of semiconductor materials, usually silicon.
    • When sunlight (photons) hits the surface of a solar cell, it gets absorbed by the semiconductor material.

    2. Excitation of Electrons

    • The absorbed photons provide energy to electrons in the silicon atoms, causing them to get excited and break free from their atomic bonds.
    • This process creates electron-hole pairs (negatively charged electrons and positively charged holes).

    3. Electric Field Creates Current

    • Solar cells have an internal electric field created by a PN junction (a junction between positive (p-type) and negative (n-type) semiconductor layers).
    • This field forces the free electrons to move toward the n-layer, while the holes move toward the p-layer, creating an electric current.

    4. Electricity Generation

    • The movement of electrons creates direct current (DC) electricity.
    • Metal contacts on the top and bottom of the solar cell collect this current and send it to an inverter, which converts DC to alternating current (AC) for practical use in homes and businesses.

    5. Power Distribution

    • The AC electricity can be used to power devices, stored in batteries, or sent to the electrical grid.

    Types of Solar Cells

    There are several types of solar cells, each with unique characteristics and efficiency levels. The most common types include:

    1. Monocrystalline Solar Cells

    Monocrystalline silicon cells are produced using a process similar to that used for transistors and integrated circuits. They are clean, resembling deep blue glass due to their blue crystals. Monocrystalline solar cells are made from single crystalline silicon and have a cylindrical shape. To maintain cost and performance, manufacturers cut out the four sides of the cells, giving them their distinctive appearance. This technology undergoes slow degradation, typically 0.25%-0.5% a year.

    2. Polycrystalline Solar Cells

    Polycrystalline solar panels, introduced in 1981, are a type of solar cell that uses melted and poured silicon into square molds, forming perfectly shaped square cells. These cells are made up of multiple crystalline structures that form a pattern on the cell’s surface. Although they have slightly lower conversion efficiency than single crystalline cells, the manufacturing process is less exact, resulting in lower costs. Module efficiency averages about 15%-16%, and degradation is slow and gradual, similar to single-crystal cells. The multicrystal patterns can be seen on the cell’s deep blue surface.

    3. Thin-Film Solar Cells

    Thin film solar cells are modules made by placing multiple thin layers of photovoltaic material on top of each other. There are various types, including amorphous silicon, cadmium telluride, copper indium gallium selenide, and organic PV cells. The efficiency rates for these cells range from 7% to 13%, depending on the technology used.

    Since 2002, there has been a significant increase in knowledge and popularity for thin film solar cells, leading to increased research and development. Future models may have efficiency rates of 10-16%. Thin film solar panels are made by depositing a thin layer of a photovoltaic substance onto a solid surface, such as glass. These materials create different types of solar panels, but all fall under the thin film solar cell umbrella.

    4. Perovskite Solar Cells

    Perovskites are a family of materials with high performance and low production costs, particularly used in solar cells. They are commonly used in photovoltaic (PV) solar cells, specifically metal-halide perovskites, which are made of organic ions, metals, and halogens. These materials are the main absorbing material in a perovskite solar cell, which absorbs light and excites charged particles called electrons. When these excited electrons are extracted, they generate electric power. Perovskite cells are referred to as thin-film due to their thinner active layers compared to crystalline silicon PV.

    5. Bifacial Solar Cells

    Bifacial solar panels offer several advantages over traditional solar panels, including increased power generation, UV resistance, reduced risk of induced deterioration, and reduced system costs. They can be placed on transparent materials, generating additional electricity from the backside, resulting in 30% increased productivity and cleaner air. Bifacial panels come in various styles, including mounted, dual-glass, and transparent back sheets.

    They use crystalline silicon cells and can be installed at different angles from the ground. While bifacial panels can be used in commercial applications like pergolas and ground-mounted systems, they are not suitable for rooftop deployment. They are best used in industrial or communication infrastructures where panels are tilted and angled away from a mounting surface. Bifacial solar panels are now comparable to traditional solar panels in terms of efficiency and space usage.

    Advantages of Solar Cells

    The widespread adoption of solar cells is driven by their numerous benefits, including:

    1. Sustainable

    Renewable energy harvesting is supported by photovoltaic cells, which are used to create solar panels for residential installations and solar street light systems. Since the sun is a limitless source of energy, these are sustainable solutions. Furthermore, it doesn’t require inputs from fossil fuels like coal, natural gas, and petroleum.

    2. Environmentally Friendly

    Compared with other renewable energy sources, solar PV systems are the most favorable as they provide clean energy. They also create very minimal obstructions in the environment, compared with hydroelectric plants, nuclear and wind power plants.

    3. Eliminate Monthly Electric Bills
