Know Which Type of Solar
System for Home is The Best
As the demand for electricity is continuously rising, the world is looking for cost-effective alternatives to meet their energy requirements. Over the last few years, solar energy has become a popular renewable energy source because of its falling costs and improving efficiencies. Sun is an inexhaustible source of power, and solar panels play a key role in harnessing this energy for a plethora of activities in everyday life. In fact, solar panels are an efficient way to offset your energy costs; it helps to combat greenhouse gas emissions and minimize your collective dependency on fossil fuels. A solar system for home can be defined as a set-up which is responsible for generating electricity by utilizing the solar energy system.
To install a solar panel system, you need to consider a lot of things, one of which is what type of solar panels to get. Most solar panels today can fit into two broad categories: Monocrystalline PERC panels and Polycrystalline solar panels.
Monocrystalline PERC Panels
Monocrystalline PERC panels are made using single silicon crystals, whose appearance is in a uniform black shape that includes purity. These panels are 2.5% more efficient when compared to polycrystalline panels, and they function better under adverse conditions like low-light. Mono PERC solar panels are space-friendly, and they can be installed on small rooftops.
Mono PERC panels are the most popular solar panels used in rooftop solar installations. The solar cells within Mono PERC panels come with an additional back layer film which helps them to absorb scattered or reflected sunlight resulting in achieving higher power generation which makes them a popular choice among homeowners. You can easily identify a monocrystalline panel by the shape of the silicon wafers, that are in octagon shape with the corners cut off.
Construction:
Each of the single solar cells contain a silicon wafer that is made with the help of a single crystal of silicon. The single crystal is formed using a method in which a seed crystal is placed into a vat of pure molten silicon at a high temperature. The seed is drawn up, and the molten silicon forms around it, creating one crystal. The large crystal is sliced into thin wafers that are used for making the solar cells. Generally, mono PERC panels comprise of either 60 or 72 solar cells, depending on the size of the solar panel.
Performance:
Monocrystalline PERC panels have the highest efficiency and power capacity when compared to the different types of solar panels. The efficiencies can range from 17% to 22%. Higher efficiency of monocrystalline PERC panels means that they need less space to reach a given power capacity. In other words, you would require less monocrystalline PERC solar panels in your solar system for home to generate the same amount of power.
Polycrystalline Solar Panels
Polycrystalline solar panels comprise of several silicon crystals fragmented together, and their color is in the shade of blue with a pattern that is unique from the mono PERC panels. Polycrystalline panels offer PID (Potential-Induced Degradation) resistance technology which offers a high degree of safety against power failures. These solar panels are an ideal choice for those who want to get an inexpensive solar solution with excellent low light efficiency and anti-reflective coating.
Construction:
Polycrystalline solar cells are manufactured using a seed which is placed into molten silica; instead of pulling out the silicon seed crystal, the whole vat of silicon crystals is cooled down. Just like mono PERC panels, polycrystalline panels generally contain 60 or 72 cells.
Performance:
Polycrystalline panel efficiency will ideally range between 13% to 17%. However, with technological advancements, polycrystalline panels are slowly moving closer in efficiency to monocrystalline PERC solar panels than they have been in the past.
