#1. Types Of Solar Panel
While installing solar panels, selecting the type of solar panels is the biggest dilemma. A difference in the efficiency and designation of the panels gives rise to a different type.
Out of plenty of solar panel types discovered so far, there are three most successful kinds of solar panels that are easily available in the market.
These solar panels are different from each other on the basis of their formation, their efficiency, their color and their cost. The types are as follows.
And out of the above three types, mono and poly-crystalline solar panels are popular traditional solar panels that most of the households in India are well introduced to. The third one, the bifacial module, is the latest kind of solar panel that is equipped with advanced technology to provide the highest efficiency.
#2. Mono V/s. Poly V/s. Bifacial
While deciding upon the best type of solar panels for your home, you must be aware of the strength and weaknesses of all the types available. In this section, you’ll find out the difference between the basic composition and functionalities of the three types of solar panels.
Mono crystal solar panels are made out of highly pure single piece silicon. While on the other hand, poly crystal solar panels are made out of fragments of silicon which were melted together to form the wafer. Bifacial panels can be made of any of these traditional solar cells though they are usually monocrystalline cells.
Comparing the energy efficiency of the three types of solar panels, Monocrystalline panels are over 20% efficient while polycrystalline panels are somewhat less efficient with an energy efficiency lying between 15-17%. Being highly advanced, bifacial solar panels are most efficient with an efficiency rate that can go high to 27%.
#3. Polycrystalline Solar Panel
Polycrystalline solar panels are also called multi-crystalline or many-crystal silicon panels. Many silicon crystals are melted together to form the wafers of polycrystalline solar panels. The silicon ingots used to form these panels are low in purity.
The angles of cells in polycrystalline solar panels are uncut from edges and the cells are square in shape. The formation of these panels involves no wastage and that’s what makes the panels highly affordable when compared to other types.
Polycrystalline solar panels are blue in color. Though the composition of the panels results in providing several remarkable features, it makes the panel less efficient and less heat tolerant.
In a nutshell, polycrystalline solar panels are a solution to homeowners who want to install an affordable solar system with cost-effective solar panels that are moderately efficient.
#4. Monocrystalline Solar Panel
Mono crystal panels are made out of a single piece of silicon. Highly pure silicon is used to make these panels. Highly pure silicon is used to make these panels.
Monocrystalline solar panels, also known as single crystalline silicon solar panels, are dark black. The edges of cells in monocrystalline solar panels are cut off to avoid the maintenance cost and also to increase its efficiency level.
The composition of monocrystalline solar panels makes them most space-efficient and highly durable and efficient. It reduces the risk of potential failure while increasing the life expectancy of the panels as high as 25 to 35 years.
As a consequence, monocrystalline solar panels are highly popular for being used in most Indian houses. If high production output and space efficiency are your priorities, the monocrystalline solar panels are for you.

#5. Bifacial Solar Panel
Bifacial solar panels are composed of cells that can be monocrystalline or polycrystalline. But they are different from the traditional solar panel types as they can produce power from both sides of the panel.
The bifacial solar panels are designed in a way that allows the modules to equip both of their sides to absorb the sunlight coming from the sun to convert it into electricity. This feature increases the efficiency of the panels to a significant amount.
This new invention in the field of solar panels has entered the mainstream with a huge list of highly advanced features including UV resistance on both of its sides. The panels reduce the balance of system costs along with reducing the concern of potential-induced degradation.
So for the individual who aims to have a highly advanced form of solar panels that performs best in every condition, bifacial solar panels are next to perfect.

Thin Film Solar Panel
Thin film solar panel is made out of a number of materials. As realize by its name, it is thinner than poly-crystalline or monocrystalline solar power panels. This solar panel comes both blueish and blackish colors, depending upon its making material. But thin film solar panel are now obsolete and therefore not used in India anymore.

#7. Which Solar Panel is Better?
All types of solar panels have their pros and cons. There is no ultimate best solar panel type that can suit the preferences of every customer. It certainly depends on several factors like personal preferences, space constraints and solar financing.
We are here to guide you to find out the best type of solar panel for your home, putting forward information based on the experience of the customers.
Monocrystalline solar panels are proven to be the best kind of solar panels available in the market. These are considered to be premium solar products. Though the panels are moderately expensive, they perform great and cost-effectively in almost all temperature conditions.
#8. Mono & Poly Price Comparison
The price of solar panels is determined using their solar price per watt. The price per watt (average) of polycrystalline panels is around Rs.22 while it is Rs.24 for monocrystalline.
|Solar Panel Model||Mono Panel Price||Poly Panel Price|
|50 Watt Solar Panel||Rs. 1,600||Rs. 1,500|
|100 Watt Solar Panel||Rs. 3,200||Rs. 3,000|
