Perc solar panels are fairly new on the market and they are becoming increasingly popular, especially in the commercial solar sector. But what are they and how do they work?

The other types of panels used for domestic properties are Polycrystalline Solar Panels, Amorphous thin-film solar panels, and monocrystalline solar panels.

PERC Solar Cells

What are PERC solar cells?

The PERC acronym stands for “passivated emitter and rear contact” or “rear cell.” PERC solar panels use PERC cells, which have an extra layer on the back of traditional solar cells.

This additional layer enables greater amounts of light to be absorbed and converted into electricity, resulting in greater efficiency than traditional solar cells.

Types of PERC Solar Modules

Mono PERC cells

Monocrystalline solar cells are cut from a single sheet of silicon, resulting in higher efficiency than polycrystalline panels. PERC layers can also be utilized to boost efficiency even more.

Poly PERC cells

Polycrystalline cells are a combination of silicon shavings, which are less efficient than mono cells but cheaper.

Adding a PERC layer to polycell efficiency improves it significantly, as with mono cells.

Poly PERC cells, on the other hand, aren’t being utilized at the same rate as mono PERC cells.

How do PERC solar cells work?

The extra layer on the back of the cell allows for more photons (light particles) to be absorbed. This increases the amount of electricity that can be generated from a given amount of sunlight.

The higher efficiency means that PERC solar panels can generate more electricity from the same amount of sunlight as traditional solar panels.

Why are PERC solar cells becoming increasingly popular?

PERC solar cells are becoming increasingly popular because they offer a number of advantages over traditional solar cells.

The lifespan of PERC solar panels

The lifespan of PERC solar panels is 25 years or more. The longer lifespan is due to the fact that PERC solar panels are less likely to degrade over time than traditional solar panels.

The different sizes

The sizes available are the same as the other domestic solar panels. Solar panels can either be 60-cell or 72-cell in design. A single solar cell is shaped like a 6×6 square.

Solar panels are organized in a 6×10 grid with 60-cell modules. 72-cell modules are arranged in a 6×12 grid, resulting in a height difference of approximately 1 foot (30 cm).

PERC solar panel working temperature

Perc Solar panels are typically tested at 77°F and rated to operate at peak efficiency between 59°F and 95°F.

Solar panels, on the other hand, can reach as high as 149°F in the summer. When your solar panel’s surface temperature rises this high, their efficiency might be reduced somewhat.

The Advantages Of PERC Solar Panels

Here are some of the advantages of PERC solar cells:

  • Increased Efficiency – PERC solar cells are more efficient than traditional solar cells, meaning that they can generate more electricity from the same amount of sunlight. This makes them ideal for use in areas with limited space, such as roof tops.
  • Longer Lifespan – PERC solar cells have a longer lifespan than traditional solar cells, meaning that they will last for 25 years or more. This makes them a good investment for those looking to generate electricity over the long term.
  • Less Degradation Over Time – PERC solar cells degrade less over time than traditional solar cells. This means that they will continue to generate electricity at a high level of efficiency for many years to come.
  • Wide Range of Applications – PERC solar cells can be used in a wide range of applications, from domestic to commercial. This makes them a versatile option for those looking to generate electricity.

The Disadvantages Of PERC Solar Panels

Here are some of the disadvantages of PERC solar cells:

  • High Cost – PERC solar cells are more expensive than traditional solar cells. This makes them a less affordable option for those on a tight budget.
  • Limited Availability – PERC solar cells are not widely available and can be difficult to source. This may make them unsuitable for those looking to install solar panels in the near future.

How Much Do PERC Solar Cells Cost?

In 2020, average system prices in the residential sector was be $3.10 per watt with microinverters and monofacial, monocrystalline PERC solar modules used.

Are there government schemes to help with installation?

The UK government has committed £4 billion to solar panel and heat pump installations as a result of the ECO4 initiative.

Local authorities will be able to set eligibility criteria that are based on local demands and circumstances.

This is due to the fact that previous rules had excluded many people who needed financial assistance.

What’s unusual about the ECO4 program is that it accepts applicants from a variety of backgrounds, not just individuals on lower income; the state of the home, the number of people living there, and so on are all factors.

How Do I Know If PERC Solar Panels Are Right For Me?

If you’re looking for solar panels that are efficient, have a long lifespan, and are less likely to degrade over time, then PERC solar cells may be the right option for you. However, they are more expensive than traditional solar cells and can be difficult to source.

You should also bear in mind that the UK government’s ECO4 initiative only covers installation costs, not the cost of the solar panels themselves.

FAQs

Are mono perc solar panels any good?

Yes, mono perc solar panels are a good option if you’re looking for solar panels that are efficient and have a long lifespan. However, they are more expensive than traditional solar cells and can be difficult to source.

What is the advantage of PERC solar cells?

PERC solar cells are more efficient than traditional solar cells, meaning that they can generate more electricity from the same amount of sunlight. This makes them ideal for use in areas with limited space, such as rooftops.

What does “perc” mean in solar panels?

Perc means “passivated emitter and rear contact”. It is a type of solar cell that has an extra layer of material on the back, which helps to reduce light reflection and increase the amount of electricity that can be generated from the same amount of sunlight.

What is the difference between perc and monocrystalline solar panels?

Perc solar cells are more efficient than traditional monocrystalline solar cells, meaning that they can generate more electricity from the same amount of sunlight. This makes them ideal for use in areas with limited space, such as rooftops. Monocrystalline solar cells are made from a single crystal of silicon, whereas perc solar cells are made from multiple crystals of silicon.
