A solar panel comprises photovoltaic cells, which absorb sunlight and convert it into electric current. These cells are connected to make a solar panel, which can be used to generate electricity for a home or commercial building. There are different types of solar panels, and each has its features. If you want to install solar in Pakistan on your property, you must understand the differences between the different solar panels.
Monocrystalline
Monocrystalline solar panels are one of the most common types of photovoltaic solar cells, which convert sunlight into electricity. These cells are made up of monocrystalline silicon crystals that are then exposed to sunlight. The sunlight knocks loose electrons in the solar cells, producing electricity. Since their invention in 1955, monocrystalline solar cells have been widely used in solar energy systems.
Monocrystalline panels have a higher heat tolerance than polycrystalline panels, which can reduce the lifespan of your system. However, industry observers say the impact is minimal in the long run. Still, it would help if you considered the climate in which you plan to install your solar panels before making your final decision. For example, if your home is in a desert climate, it is best to opt for monocrystalline solar panels.
PERC
PERC solar cells are a recent development in the solar industry that are essentially modified silicon cells with a reflective layer on the back. This reflective layer sends unused light back across the junctions of the solar cells, reducing rear recombination and enhancing efficiency. The reflective layer also helps to avoid heat build-up in the cells, which can decrease their performance. PERC solar cells are relatively easy to make and can be added to polysilicon or monosilicon solar cells. These solar cells also work well in bifacial applications.
The two most common PERC solar cell types are polycrystalline and monocrystalline. Monocrystalline panels are cheaper to produce and use a single piece of silicon. In general, monocrystalline cells produce more energy per watt. However, a second PERC layer can be added to polycrystalline panels to improve their efficiency without increasing manufacturing costs.
Thin-film
If you’re looking to reduce your carbon footprint and save money on energy, consider buying thin-film solar panels. These panels are lightweight and can be portable. But there are a few important factors to consider before purchasing this type of solar panel. These panels don’t have the same performance as traditional solar panels and require more space and support elements, such as wiring and mounting brackets.
