Solar Panels


A solar panel, often known as a PV panel, is a device that transforms solar energy into usable electricity for electrical loads. A PV panel consists of several photovoltaic (PV) cells connected in series. Silicon, phosphorous (which produces the negative charge), and boron (which produces the positive charge) are the three major elements that make each solar cell’s layers.

The current that results in the generation of green power is known as the “Photovoltaic Effect.” Following that, the solar panel’s output of electricity is converted into alternating current and delivered into your home’s electrical system via an inverter

When sunlight strikes the surface of a solar panel, the solar energy packets (known as “photons”) are absorbed through the PV cells. It allows the cells to charge and begin vibrating. After that, it produces the power necessary for free electrons to be released into the electric field and drawn into a directed current.

PV panels have several uses other than creating electricity for homes, such as remote power systems for cabins, telecommunications gear, and remote sensing. In this article, we will discuss PV panels. You can find these panels at a discount on Tecno Wear.


Various types of PV panels are available on the market today, each providing a particular demand and purpose. Thus, it is vital to understand the difference between these before making any choice.

There are four different kinds of PV panels available on the market today, which include

  • Monocrystalline
  • Polycrystalline
  • Passivated Emitter and Rear Cell (PERC)
  • Thin-film panels


Monocrystalline panels are the most advanced and oldest of all four types. It is the most often used component in rooftop PV panel systems due to its power output and efficiency.

Monocrystalline panels, often called single-crystal (crystalline) panels, are produced from a single pure silicon wafer split into multiple crystals. These are the most durable PV panel options, and they look black because of the way sunlight interacts with silicon.

As compared to other kinds of panels, monocrystalline has a higher pricing point, but when it comes to their performance, these panels are the finest at doing their job.


These panels are often known as “multi-crystalline” panels because they consist of several crystal fragments, unlike monocrystalline panels, which are made of one crystal only.

Silicon solar cells are also used in polycrystalline panels. However, their cooling process differs from that of monocrystalline panels; therefore, they are similar to monocrystalline panels in that way.

They are designed as a more accessible alternative to monocrystalline panels and are relatively efficient and cost-effective for the typical user.

Passivated Emitter and Rear Cell (PERC)

PERC solar cells have an additional layer on the backside that reflects some of the sun’s rays into the solar cell, increasing energy conversion and making them an ideal option for homeowners with smaller roofs. They also perform well in high-heat and low-light environments, with a 3% increase in efficiency compared to other conventional panels.

Thin-film solar panels

Thin-film panels are the most recent innovation in solar energy. These panels are made from materials including copper indium gallium selenide, cadmium telluride, and amorphous silicon.

Glass is placed on top to protect them, and these materials are sandwiched between thin sheets of conductive material. Thin-film panels can be black or blue and, as their name implies, are thin in texture (approximately 350 times thin as the other panels discussed above).

Thin-film panels, the least effective of all PV panels, are typically utilized in industrial environments.

All these different types of solar panels are available for purchase at Tecno Wear. We are offering these panels at a discount of 10%. Click the link and add one to your cart right now.

Benefits and drawbacks of solar panels


  • Significantly reduce your electricity bill
  • Lower your carbon footprint
  • Increases the worth of your home if you decide to sell it


  • Initially, it can be expensive to install
  • Lower your carbon footprint
  • Increases the worth of your home if you decide to sell it

Solar Panel Types by Efficiency

  • Most Effective: PERC

PERC panels are 5–6% more efficient than monocrystalline panels.

  • Effective: Monocrystalline

The efficiency of monocrystalline panels ranges from 17% to 22%

  • Least Effective: Thin-Film Panels

The effectiveness of thin-film panels depends on the type of PV material used in the cells; typically, the range is between 6% and 13%, with amorphous silicon having the lowest rating.

Solar Panel Types by Power Capacity

  • Highest power capacity: monocrystalline panels and PERC panels
  • Mid-Tier: Polycrystalline Panels
  • Lowest power capacity: thin-film panels

Factors to keep in mind before buying

  • Location
  • Longevity of Residence
  • Roof


Finding the ideal type of PV panel for your place can be a bit of a challenge for many; however, by keeping your requirements in mind, you can make the perfect choice with the help of this article.

We sincerely hope this article has given you enough ideas to help you decide which solar panel to buy. You can shop for these panels here at Tecno Wear. However, if you are still unsure which one to buy, contact us, and we will be delighted to serve you.


What is the cost of solar panels?

The average cost of installing these panels can range from $10,000 to $35,000, with the median around $15,000, depending on the number of panels you need.

Can PV panels work for me if I live in a cloudy or snowy area?

When cloudy, these panels produce less power and generate no power at night. However, any power which is generated but not used throughout the day will be stored in the battery for later use. The snow will stop panels from converting sunlight into electricity, but most PV panels are slanted, allowing snow to slide off without causing structural issues.

Will I still receive an electrical bill if I have PV panels?

You will still receive an electrical bill; however, it will be lower than the bills you currently get, in some cases $0.

Where can I buy solar panels?

You can buy these high-quality panels at Tecno Wear. We offer these panels at discounted prices.
