Tezzbuzz Desk- To reduce the rising electricity bills, a large number of people are now installing solar panels on the roof of their houses. But due to different types of solar panels available in the market, it is not easy for people to choose the right option. Especially regarding monocrystalline and polycrystalline panels, there is often a question as to which of the two produces more power and which would be better for a roof with limited space.

If you are also planning to install a solar system at your home, then before purchasing the panels, it is important to understand their efficiency, price, available space and power requirement.

What is the difference between monocrystalline and polycrystalline?

Monocrystalline solar panels are made from a single type of silicon crystal. Their color is usually dark black and they are considered more efficient panels. These panels can be especially useful when more power output is needed in a smaller space.

Whereas, polycrystalline panels are made by combining several silicon crystals. Their color often appears blue. Their efficiency is usually lower than monocrystalline panels, but their initial cost can be lower in many cases.

If you want more power in less space then monocrystalline is better

The most important thing while choosing a solar panel is its efficiency. This means the amount of sunlight the panel can convert into electricity. Modern monocrystalline panels generally provide higher efficiency than polycrystalline panels. In such a situation, if the space on the roof of your house is limited and you want to generate more electricity from the same area, then monocrystalline panel can be a better option.

For example, a higher efficiency panel can be installed over less ceiling area for the same capacity system. However, actual production does not depend solely on the type of panel. Availability of sunlight, angle of the panels, shade, temperature, system design and quality of the inverter also affect power output.

Even in extreme heat, the efficiency of the panel is affected.

In a country with hot climate like India, the effect of temperature should not be ignored while purchasing solar panels. As a solar panel gets hotter, there may be some reduction in its output capacity. Therefore, buying a panel just by looking at the efficiency is not the right decision. Nowadays monocrystalline panels with modern technologies like TOPCon and HJT are also available in the market. Features like better temperature performance and high efficiency are seen in these. However, the performance of a panel depends on the technical specifications of its model and manufacturer.

When might polycrystalline be a good choice?

If you have enough roof space and your budget is limited, polycrystalline panels can also be considered. Their efficiency may be lower than monocrystalline, so more space may be required to produce the same power. In such a situation, the decision should not be taken just by looking at the price of the panel. The panel's warranty, expected life, efficiency, temperature coefficient, manufacturer's reliability and quality of installation should also be taken into consideration.

Keep these things in mind before buying

When purchasing solar panels, assess the available roof space and average power consumption of your home. After this, get information about the system capacity and estimated annual production from the installer.

If there is less space on the roof and more power output is required, then monocrystalline panel There may generally be a more suitable option. At the same time, consumers who give priority to adequate space and budget polycrystalline panel Can consider.

However, don't make the final decision based only on the type of panel. Before purchasing, please check the actual efficiency, temperature coefficient, warranty and technical information of the manufacturer of the concerned model. Good installation with the right panel and choosing the right capacity inverter is equally important.
