Types of Solar Panels

Solar panels are considered essential components in harnessing solar energy for various applications, including both off-grid and on-grid solar systems.

The residential solar segment in India has been fast growing and has a projected CAGR of about 24% during 2024 to 2029.

Every panel type offers a unique advantage, making them a better choice for different applications in on-grid solar systems.

Below is an overview of the three notable types:

Polycrystalline Solar Panel

Polycrystalline solar panels are a great option for both residential and commercial users looking to save on upfront costs.

This type of panel can efficiently produce electricity for 25 years or more.

Composition: Made by incorporating multiple silicon crystals that are melted together.
Appearance: Typically has a blue hue with a pattern of dots.
Efficiency: They do offer moderate efficiency levels.
Cost: Highly affordable due to its simple manufacturing processes.
Ideal Use: Suitable for large solar panel installations, where space is not a constraint.

Mono PERC Half-Cut Bifacial Solar Panel

Mono PERC Half-Cut Bifacial solar panels are a better choice for users having limited installation space.

While they may have a higher initial cost compared to the traditional panels, the increased energy output does offset the investment over time.

These panels come with a lifespan of approximately 25 to 30 years.

Mono PERC Technology: Stands unique for Monocrystalline Passivated Emitter and Rear Cell. This technology enhances efficiency by adding a passivation layer on the rear side of the cells.
Half-Cut Cells: Cells are wisely cut into halves, further reducing resistance and improving overall performance.
Bifacial Design: Generates power by capturing reflected light from both sides, front and back.
Efficiency: Higher efficiency is possible here due to combined technologies.
Ideal Use: Perfect on grid solar system type for areas having reflective surfaces like sand, that can maximize energy production.

TOPCon Solar Panels (N-Type Panels)

TOPCon solar panels are a better choice for users seeking high durability and efficiency in their solar panel installations.

Their superior performance does lead to better long-term returns of investment. These panels have been designed to last between 25 to 30 years, providing solid power generation all throughout their lifespan.

Technology: TOPCon does stand for Tunnel Oxide Passivated Contact. It utilizes a thin oxide layer to reduce electron recombination, further enhancing efficiency.
N-Type Silicon: Utilizes phosphorus-doped silicon for better performance and longevity.
Efficiency: Provide higher efficiency rates when compared to the other types of on grid solar system.
Degradation: Exhibits lower degradation over time, further ensuring sustainable performance.
Ideal Use: Highly suitable for both residential and commercial installations aiming for long-term use.

Factors You Must Consider to Choose the Right Type of Solar Panel

While selecting a solar panel for installation, you must evaluate certain key factors to ensure the system aligns with your energy generation requirements and given environmental conditions.

Efficiency

To achieve higher efficiency, make sure to measure the proportion in which the panel can convert sunlight into usable electricity.
Highly efficient panels do generate more power per unit area, further making them an ideal choice for locations with limited space.

For example, monocrystalline panels are capable of generating better power production when compared to polycrystalline ones.

Cost

Get to the initial investment and the long-term financial benefits you can have out of installing any type of solar panel in your place.
Highly efficient panels can have a higher upfront cost, but it leads to greater energy savings over time.
Strike a balance with your budget to yield better power output and achieve desired performance expectations.

Durability & Lifespan

Understand the average lifespan and the warranty options provided for the panels.
Panels that are constructed using high-quality materials do offer longer durability, further ensuring reliable performance over decades.

Weather Suitability

Evaluate the ways the panels can perform under local climatic conditions.
Monocrystalline PERC (Passivated Emitter and Rear Cell) and TOPCon (Tunnel Oxide Passivated Contact) panels can perform well in low-light conditions

Purpose & Application

Define whether the installation is for commercial, industrial, or residential use.
For residential setups, you need to prioritize aesthetics and space efficiency, while industrial and commercial installations must focus on maximizing energy output to meet higher power demands.

By carefully analyzing and following these factors, you can wisely select a solar panel system that meets your energy production needs.

What to Expect in Solar Panel Installation in 2025

Lower Prices: With continuous advancements in solar technology, domestic manufacturing, and government policies, we can expect the installation and panel purchase prices to drop by 10 to 15%.
Increased Capability: New technologies like perovskite and bifacial solar panels are about to be more affordable and offer better efficiency.
Battery Storage Growth: With the rise of EVs (Electric Vehicles) and the demand for on grid, off grid, and hybrid systems increasing day by day, energy independence is not so far to achieve.
Government Support: Expect easier net metering policies, better subsidies, and more incentives from the Indian Government in 2025 to encourage the use of solar energy for everyday purposes.

Conclusion

To make the right investment in solar panels, align the type of panel with your energy needs. Consulting with experts will help you understand the most efficient options and the economic benefits of solar panels.
