Do you want to install a rooftop solar system at your house? If you’re ready to embrace green energy and adopt a sustainable power source, the first crucial step is selecting the right solar panels for your home.
You may have come across the categories of Monocrystalline vs. Polycrystalline Solar Panels efficiency. Both types harness the sun’s rays to generate electricity through the photovoltaic effect. It’s easy to get confused between the two. But don’t worry, we have your back
In this blog, we will make a detailed analysis of Monocrystalline Vs. Polycrystalline Solar Panels efficiency and help you select the best solar system.
Let’s begin by understanding the concept of solar panels.
What is Monocrystalline Solar Panels?
Photovoltaic solar panels are best suited for residential use. They do not require complex installation and are easy to operate. Monocrystalline panels are made from monocrystalline silicon cells that are wire-cut into an octagonal-shaped wafer. This allows better electricity flow due to more space.
The silicon has a unique dark blue color that’s easy to detect. A monocrystalline solar panel will contain approx 60 to 72 solar cells, depending on the size of the panel. The name is derived from high-purity silicon molded into a single structure. Some of the basic features of mono solar panels are:
1. High-Efficiency
Monocrystalline panels are efficient as the single crystal structure allows for better electric flow. This means they can generate more electricity, resulting in high energy conversion. The efficiency range is between 25%-30%, which is higher than other solar panels.
2. Space-efficient
Solar panels have the capacity to produce a lot of energy in a relatively small area. Moreover, gradual technological advancements have increased the power output exponentially. This makes them a good choice for limited roof and ground space.
3. Longevity
Mono panels have a long shelf life, exceeding 25 years with proper care and maintenance. They are durable and can withstand severe environmental conditions.
Before comparing monocrystalline vs. polycrystalline solar panels efficiency, let’s take a look at poly solar panels.
What are Polycrystalline Solar Panels?
The structural contrast between Monocrystalline and Polycrystalline Solar Panels is evident in their composition. Unlike Monocrystalline panels, Polycrystalline solar panels are crafted from multiple crystal structures, formed by melting and shaping silicon into tiny cubes, impacting their efficiency in Monocrystalline vs. Polycrystalline solar panels efficiency comparison.
The thinly-cut wafers are formed in an amalgam to cut production costs. This makes the process easier. Some of the key features are listed below
1. Lower Cost
Poly solar panels are less expensive than mono solar panels and easier to produce. This is a cost-effective solution for solar panel operators.
2. Slightly Less Efficient
Polycrystalline panels are less efficient at converting sunlight into electricity. The solar cells are neatly stacked side by side, leaving less room for the electrons to move freely. The efficiency ranges from 15% to 25% which is less than the efficiency rate of mono panels that are around 25% to 30%.
3. Space Requirement
They need more space to generate electricity. Areas with limited space will not benefit from polycrystalline solar panels.
Now that you are clear about mono and poly solar panels, it’s time to do a comparative analysis of Monocrystalline Vs. Polycrystalline solar panel efficiency.
