Types of Solar Panels: What Should You Know?

Types of Solar Panels

If you have already started shopping the different types of solar panels, you might have probably noticed that they don’t all really look exactly alike. But it’s not simply about a cosmetic difference. Yes, solar panels don’t all work or perform the same way. Each of the types have different capabilities, energy-efficiency levels, and even complete installation costs.

Wondering which sort of solar panels are perfect for you? The finest possible solar panel option for your home is going to depend on your budget. You must consider the cost to install, roof space, overall access to sunlight, and energy-efficiency.

Monocrystalline solar panel

Monocrystalline Solar Panel cells are the ones that tend to accomplish higher levels of efficiency. This is because they use more pure silicon to make them. You are going to notice a uniformity in their overall coloring. Their cylindrical shape even helps these cells accomplish a higher level of efficiency. Once choosing between a monocrystalline and even polycrystalline solar panel system, it is going to be important to find your overall solar sun number score. This is going to permit you to find out how much caliber your system will have with your overall place or location and the amount of sunlight it gets.

How are they made?

Remember to make them, solar manufacturers like Loom solar carve silicon ingots into proper wafers. In the process, they smooth and even round the cell edges. Since the form and content they have helps them generate more electricity, you would require less of them. But you know what, monocrystalline cells even cost more to manufacture than any sort of polycrystalline solar panels. For this reason, they are pricier to purchase. On the other side, they incline to last longer, and they even often come with long warranties. The good news is that both types of solar panels are easy to install on your roof or even by installing solar panel mounts on a chosen area of your land.

What is the efficiency rating?

Remember that the efficiency ratings of this type of solar panel range from 17% to even 22%. It earns them the overall title of the most efficient solar panel type. The higher efficiency rating of monocrystalline panels actually declares them perfect for homes with minimal roof space. It is because you would need fewer panels to produce the electricity you desire.

Monocrystalline panels have their manufacturing procedure to thank for being so effective and efficient. Because monocrystalline solar cells use a single crystal of silicon, electrons are in a position to easily flow across the cell, enhancing the overall efficiency.

Not only do monocrystalline type of panels have the highest efficiency ratings, but they even typically also have the highest power volume ratings, as well. Most of the monocrystalline panels on the market at the present time will have a power output rating of a minimum three hundred watts, but can go up to even nearly three hundred seventy-five watts or higher!

Polycrystalline panels

These are the panels that are sometimes referred to as multicrystalline panels. These are popular among homeowners looking to install solar panels on a specific budget. Similar to monocrystalline panels, polycrystalline panels are formed up of silicon solar cells. However, the cooling procedure is somewhat different as it actually causes multiple crystals to develop, as opposed to one. Remember that the polycrystalline panels on residential homes ususally include sixty solar cells.

Polycrystalline panels are less efficient than their mono counterparts. The melted silicon fragments have less space for the electrons or negative atoms to move around. Therefore, the efficiency rating of polycrystalline panels is only 13 to 16 percent. But the latest manufacturing innovations paved the way for polycrystalline solar panels to generate efficiency outputs close to monocrystalline solar panels.

While monocrystalline solar panels are highly favored for efficiency and output, this trend is about to change. The narrowing gap in the performance of poly and mono entices many consumers to choose the more affordable option. Polycrystalline solar panels are more budget-friendly without significantly compromising performance.

Thin film solar cells 

These are the cells that large-scale utility and industrial solar installations use most of the time. This is because of their overall lower efficiency ratings.

What are they made of?

Thin film solar panels are formed up of depositing a thin layer of a photovoltaic substance onto a solid type of surface, such as glass. Some of these photovoltaic substances even encompass Amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium selenide (CIGS). Each of these materials forms up a different kind of solar panel, however, these all fall under the thin film type of solar cell umbrella. During the overall manufacturing process, the photovoltaic substance develops a thin lightweight sheet that is, in some instances, flexible.

A thin film deposition system provides solar panel manufacturers with various deposition options. During thin-film deposition, the different techniques include sputtering, pulse laser deposition, thermal evaporation, and organic physical vapor deposition.

Sputtering involves creating high-quality thin film coating for solar panels using spluttered atoms. On the other hand, thermal evaporation involves using a stream of evaporated material that coats the substrate surface in a vacuum chamber.

Many manufacturers upgrade to higher-level components for modular and simple installation of thin-film solar panels, decreasing system downtime. As a result, solar panels made of thin films are considered the most cost-efficient type nowadays.

These are a newer kind of solar panel and are less popular for residences or homes. But they are absolutely growing in popularity. However, remember that thin film solar panels do incline to be less efficient than crystalline solar panels, and demand a lot of roof space. These even tend to damage more quickly, so companies or providers might offer shorter warranties to homeowners.

Also, remember that thin film is even inexpensive and more flexible in comparison with crystalline solar cells. They can be readily manufactured into shingles. So for the ones who don’t really like the appearance of solar panels on a roof, thin film can prove to be a great alternative.

Bifacial solar panels

Solar PV panels form by using one of two diverse types of crystalline cells; monocrystalline or even polycrystalline cells. The majority of bifacial solar panels using monocrystalline cells. This is because monocrystalline cells are more effective, and efficient, despite being pricier.

What makes them different?

Solar cells in bifacial solar panels are exactly the same as in the realm of monofacial solar panels. The only true difference is how they form the panel. Whereas the traditional type of monofacial solar panels have an impervious type of backsheet, bifacial solar type of panels have a reflective back or even dual panes of glass gripping the solar cells in place.  They expose the solar cells to sunlight at the back as well as the overall front.

As an outcome, bifacial solar panels have a higher level of efficiency, as they are capable of capturing overall sunlight on both sides. Since these bifacial solar panel are fully transparent, they are mostly frameless in the absence of metal gridlines. This makes them absolutely stronger in structural integrity and even easier on the eye, as well making the solar panel simpler to clean.

Conclusion

To sum up, since you have a good idea about some of the types of solar panels, make sure that you get the best ones from Loom Solar, a government-recognized start-up manufacturer of solar panels.
