Perc solar panel is a type of photovoltaic (PV) solar panel that has been gaining popularity in recent years. The term “perc” stands for Passivated Emitter Rear Cell, which refers to the technology used in the production of the solar cells. This technology improves the efficiency of the solar panel, making it more cost-effective and sustainable.
How does a perc solar panel work?
A perc solar panel is made up of several layers of material, including silicon, metal contacts, and a protective coating. The sunlight that hits the panel is absorbed by the silicon layer, which then releases electrons. These electrons are collected by the metal contacts, creating an electrical current that can be used to power appliances and devices.
What sets perc solar panels apart from other types of solar panels is the passivated emitter rear cell technology. This technology involves placing a thin layer of insulating material between the silicon layer and the metal contacts, reducing the amount of energy lost due to recombination. This means that more electrons are collected and the efficiency of the solar panel is improved.
Advantages of perc solar panels
Perc solar panels have several advantages over other types of solar panels, including:
1. High efficiency – The passivated emitter rear cell technology used in perc solar panels improves their efficiency, making them more cost-effective.
2. Better low-light performance – Perc solar panels perform better in low-light conditions, making them ideal for use in countries with less sunlight.
3. Longer lifespan – Perc solar panels have a longer lifespan than other types of solar panels, thanks to their improved efficiency and reduced energy loss.
4. Lower maintenance costs – Because perc solar panels are more efficient, they require less maintenance than other types of solar panels.
5. Sustainable – Solar energy is a renewable and sustainable source of energy that reduces our reliance on fossil fuels.
Disadvantages of perc solar panels
Despite their many advantages, perc solar panels also have a few disadvantages, including:
1. Higher cost – Perc solar panels are more expensive than other types of solar panels. However, their higher efficiency means that they can pay for themselves over time.
2. Fragility – Perc solar panels are more fragile than other types of solar panels due to the thin layer of insulating material. They require careful handling during installation and maintenance.
3. Limited availability – Perc solar panels are not yet widely available in the UK, making them harder to find and more expensive.
Conclusion
Perc solar panels are an innovative and sustainable technology that is gaining popularity in the UK. Their high efficiency and improved low-light performance make them an ideal choice for homeowners and businesses looking to reduce their carbon footprint and save money on energy bills. While they are more expensive than other types of solar panels, their long lifespan and lower maintenance costs make them a more cost-effective option in the long run. As more companies begin to produce perc solar panels, they will become more widely available and affordable, making them an excellent choice for anyone looking to invest in solar energy.
