Which Type of Solar Panel Is Best for Residential Use?  

Gujarat currently accounts for approximately two-thirds of all residential rooftop solar electricity in India, covering only 6% of its land mass.

India requires additional solar power to cover half of its electricity needs by 2030 and reach net-zero emissions by 2070. Solar presently accounts for 7% of India’s electricity generation, and the country’s solar energy potential is expected to rise rapidly. However, improvement is gradual, with solar capacity expected to reach 370GW by 2030. Gujarat has emerged as a pioneer in rooftop solar installations.

Gujarat’s residential rooftop solar segment increased from 0.085 GW in 2019 to 1.2 GW in March 2022. Despite only achieving 77% of the intended capacity, the states’ residential market share increased significantly.

The report illustrates how Gujarat achieved widespread deployment by accomplishing the following:

  • Ensuring suitable supply and demand
  • Digitization

Here’s a comprehensive guide, infused with real-world insights, to help you choose the right solar panels for residential use:

A) Assess Your Energy Needs
Calculate Your Consumption: Review your electricity bills to understand your average monthly consumption.

Future Needs: Consider any future changes that might increase your energy usage, such as new appliances or an electric vehicle.

B) Evaluate Your Roof Space
Available Area: Measure the available roof space to determine how many panels you can install.

Orientation and Tilt: Ensure your roof is oriented towards the south (in the Northern Hemisphere) and has an optimal tilt angle for maximum sunlight exposure.

C) Consider the Cost and Financing Options
Initial Investment: Compare the costs of different panels and installation services.

Subsidies and Incentives: Take advantage of government subsidies and incentives, such as the Surya Gujarat Scheme, which offers up to 40% subsidy for residential installations.

Financing Options: Explore financing options like solar loans or leases to reduce the upfront cost

Selecting the Solar Panels for Residential Use

Opting for a residential solar system can be a highly advantageous choice for residents looking to cut energy costs, generate additional revenue, and attract a larger client base through environmentally aware branding and marketing.

Considering the large investment, it is critical to ensure that the solar panels and system you choose meet the energy requirements of your residential structure.

Types of Solar Panels

Monocrystalline solar panels are known for their high efficiency and streamlined form. They are built of a single continuous crystal structure. They are suitable for homes with limited rooftop space since they produce more power per square foot.

Polycrystalline solar panels are manufactured by melting silicon crystals together. They are less efficient than monocrystalline panels but more cost-effective, making them a popular choice for residential applications.

Thin-film solar panels are lightweight and flexible, manufactured from a range of materials such as cadmium telluride and amorphous silicon. They are less efficient but useful for unusual roof forms or portable applications.

Mono PERC is an advanced version of monocrystalline panels, PERC technology adds a passivation layer on the rear side of the cell to improve efficiency by reflecting unabsorbed light back into the cell.

TOPCon (Tunnel Oxide Passivated Contact) technology builds on PERC by adding a thin oxide layer and a layer of doped polycrystalline silicon to further reduce recombination losses and improve efficiency.

HJT (Heterojunction Technology) combines crystalline silicon with amorphous silicon layers to create a high-efficiency cell. HJT panels are known for their excellent performance in high temperatures and low light conditions.

Several Benefits to Inspect Your Residential Solar System

Scale and scope: Residential solar systems can be customized to your home’s exact energy needs. Whether you need a modest system to offset a portion of your electricity consumption or a bigger system to meet all of your energy requirements, solar panels provide design and installation flexibility.
Financing alternatives: Several financing alternatives are available to help make solar systems more affordable. Solar financing options include loans, leases, and power purchase agreements (PPAs). Government incentives and subsidies can also greatly lower the initial costs.

Regulatory Considerations: Understanding local rules and building codes is critical when installing a solar system. Many regions have net metering regulations, which allow homes to sell excess energy back to the grid, increasing the financial benefits of solar power.

As India strives to meet half of its electricity needs with solar power by 2030, residential solar systems play a crucial role in achieving this ambitious goal. Not only do these systems contribute to a cleaner and more sustainable future, but they also offer significant financial benefits. With government subsidies, tax incentives, and long-term energy savings, investing in a residential solar system is a wise and forward-thinking decision.
