Also known as multi-crystalline, a poly crystalline solar panel is a variant of solar panels that comprises many silicon crystals in the PV solar cells.
Many silicon fragments are melted and combined to form poly crystalline solar panel wafers. Each cell in the panel has several silicon pieces, allowing the electrons to move freely.
These electrons convert the solar energy into electricity and supply it to nearby areas. They are used in large solar farms. They send electricity to off-grid households and remote regions as well.
While many solar panels have a black shade, the polycrystalline solar panel holds a blue shade. This shade helps in absorbing and storing more sunlight in less time.
These panels have multiple photovoltaic cells. When the sun rays fall on the PV junction, the polycrystalline solar panel charges up the electrons on the cells and makes them pass through the electric current.
These charged-up electrons transmit electricity to electric wires and power household appliances like air conditioners, washing machines, mobile phones, inverters, and heaters.
These solar panels provide noiseless operation and store additional energy for use at night or during the monsoon.
Currently, a residential solar panel produces 250 W to 400 W power for effectively conducting various household operations.
Compared to this, a polycrystalline solar panel provides 100 W to 400 W power. This difference in power capacity depends on multiple factors.
The solar output of a small residence might be 250 W, whereas it can be more for a big home. The usage, climatic conditions, and location also contribute to the efficiency of a polycrystalline solar panel.
For small households, a poly crystalline solar panel is more effective as it can reduce the upfront cost and provide valuable performance for years.
Solar manufacturers are consistently developing new technologies to make solar energy efficient. They are of three types: monocrystalline, polycrystalline, and bifacial.
All the three have different features that make them distinct from one another.
They are less efficient than monocrystalline solar panels but are cheaper than them. Moreover, they are highly sustainable.
They are more energy-efficient than the former but are expensive. They are not as long-lasting as a poly crystalline solar panel.
These solar panels are much less efficient than the other two. However, they are cost-effective and sustain for a higher period. They are easy to mount and do not require a flat surface for installation.
Like all solar panels, polycrystalline solar panels also have pros and cons. Let’s find out both!
The advantages of buying a poly crystalline solar panel are as follows:
The following are the disadvantages of buying a poly crystalline solar panel:
With an energy efficiency rate of 13% to 15%, polycrystalline solar panels are one of the cheapest solar energy systems on the market.
Since these solar panels require less energy to function, they are cost-effective too. Thus, for middle-class solar consumers, it is ideal to purchase a Poly crystalline solar panel.
The polycrystalline solar panel price depends on its size and capacity. The more the size and the capacity are, the higher the price will be.
This price range can vary based on availability, location, solar brand, and promotion. Also, this price is exclusive of the government subsidy on solar panels.
Although the polycrystalline solar panel price is direct, the solar manufacturers charge a specific fee from the homeowners after determining subsidies from the government.
The Indian government provides anywhere between 20% to 40% subsidy on the L1 price to the homeowners for setting up a polycrystalline solar panel on their residence’s rooftop.
Very recently, on the 30th of July 2022, PM Narendra Modi also launched a new National Solar Portal where a fixed subsidy is offered. Even people residing in states that do not offer a subsidy can apply for a subsidy under the National subsidy scheme the portal.
For enhancing the solar system output, maintaining the poly crystalline solar panel is essential from time to time.
Though not complicated, cleaning the system might require time and effort as it accommodates a vast space. The following are some practical ways to ensure the maintenance of a poly crystalline solar panel:
A poly crystalline solar panel is economical, eco-friendly, consumes less energy, and can function in all temperatures. Since most solar panels are generally expensive, buying a poly crystalline solar panel can help save money.
A Polycrystalline solar panel conforms to the basic requirements of a solar panel. Besides, it offers high functionality and meets modern safety needs. It is suitable for both domestic and commercial applications.
The lifespan of polycrystalline solar panels is 25 years. Homeowners can increase their longevity with good maintenance.
A 6.6kW solar panel system provides 26.4kWh of energy each day. This more or less depends on the usage.
Yes, you should consider buying a large polycrystalline solar panel. The bigger a solar panel is, the more energy can be saved.
