Solar panels are called photovoltaic solar modules, solar plates, solar PV modules, and alternative energy panel,s, etc. solar panels are made up of a bunch of 60-72 solar cells that convert sunlight into electricity.
Solar cells are made of a part called “silicon“. To manufacture the solar cells, fragments of silicon or silicon crystals are melted together during mold and cut into wafers.
If we install two or more solar battery together and connect them with a solar inverter, solar panel than it becomes a solar energy system which will be utilized in houses, companies, schools, industries, etc. solar battery is that the main a part of the system and every one variety of the system (on-grid system, off-grid scheme and hybrid solar system) contains the same style of solar battery.
Types of Solar PV Panel
Solar panels are invented in many varieties and capacities. This panel varies from one another on the idea of their formation, the material used, etc. to supply a short knowledge about every type of solar battery, we are listing its type below.
Polycrystalline solar array
Monocrystalline electrical device
Thin Film electrical device
Out of those solar panels, only polycrystalline electrical devices and monocrystalline electrical devices are the foremost successful panel to use for the home schemes and commercial schemes.
Polycrystalline Solar Panel
The polycrystalline solar battery is the most typical kind of electrical device. The efficiency rate of a polycrystalline solar array is around 16%-17%. These panels are best to figure under extreme climate. To manufacture polycrystalline solar panels, low purity silicon is employed.
Mono vs. Poly Technology
Mono vs. polycrystalline solar array both are the best variety of solar array. But often, they create good confusion while it involves choosing the best among them. Here we have a comparison between both forms of solar modules to form the choice process easy.
Which type of solar array is best?
Solar panel efficiency refers to the number of sunlight converted to electricity in a specific area. Under the above two styles of electrical device technology, monocrystalline is the best inefficiency.
The monocrystalline panel has the highest efficiency of up to twenty, requires less space but they’re a little expensive than a polycrystalline solar array. A 100-watt poly and monocrystalline panel will generate an identical amount of power but the mono-crystalline panel will take up less space than a poly-crystalline panel.
Mono-crystalline efficiency – 20%
Poly-crystalline efficiency– 17%
Solar Panel Application
The solar panel basically generates DC electricity and this electricity will be used to power a different variety of applications like solar lights, solar systems, solar pumps, and air conditioners, etc.
Battery-based solar lights are a stand-alone system that will store power from the solar array to illuminate solar street light, solar lantern, solar home lighting system, etc. Generally, an electrical device for solar lights starts from 3w to 75w.
Generally, 300-watt solar array and above rated solar panels are utilized in the on-grid scheme. The on-grid scheme range starts from a 1kW system to a 10 kW system for home purpose and 15kW system to 100kW system for commercial use.
The off-grid scheme starts from 1kW to 100kW. In off-grid solar systems, 100 watts to 330-watt solar array is employed in these kinds of schemes.
