Shams Power: Types of Solar Panel Systems in Pakistan

Solar energy systems offer a clean, renewable alternative to traditional power sources. They can also significantly reduce your high electricity bills.

However, choosing the right system is crucial for optimal performance and longevity. There are four types of solar panels in Pakistan: Monocrystalline, Polycrystalline, Passivated Emitter Rear Contact (PERC), and Thin-film.

Monocrystalline

Solar Panel systems that use monocrystalline technology are the most efficient. They are made using single-crystal silicon and use the Czochralski method to form large cylindrical-shaped ingots that are sliced into wafers. These are able to convert sunlight into electricity at an efficiency rate of 15-20%, even in low-light or warm weather conditions.

These systems are more expensive than polycrystalline solar panels, but they can save money in the long run. This is especially true if you live in an area that experiences frequent power outages and high energy bills.

A hybrid system is a great choice for those who want to reduce their electricity bills while still relying on the grid for backup. These systems can be connected to both the utility phase line and a battery connection. They also have a built-in inverter to switch between the two connections, providing you with the highest level of energy efficiency possible.

Polycrystalline

Polycrystalline solar panels are made from multiple strands of silicon that have been combined together through melting. They have a lower efficiency than monocrystalline and require more space. They are also less tolerant to heat and have a shorter lifespan than monocrystalline solar panels. 

Bifacial solar panels are designed to capture sunlight from both sides, making them more efficient than other types of PV panels. However, they can be more expensive than other solar panel types. It is important to consult a reputable solar energy provider before purchasing bifacial solar panels. It is also a good idea to have your solar panels regularly maintained by a qualified technician. This will ensure that they are delivering optimal performance throughout their lifespan. Also, a periodic check can help prevent issues from developing before they cause major problems. Keeping track of the electricity output from your solar panels can help you determine whether they are working well or not.

Passivated Emitter Rear Contact (PERC)

Longi solar panels in Pakistan are built with the latest technology and premium materials to ensure maximum energy efficiency and dependability. These panels are designed to withstand harsh weather conditions and produce more power in low-light situations, making them ideal for Pakistan’s unpredictable climate. They also use PERC technology, which improves energy conversion and performance.

PERC solar cells are a type of silicon cell with an additional layer on the back. This layer absorbs sunlight and sends unused wavelengths back across the n-type and p-type junction, allowing solar panels to achieve higher efficiencies than traditional silicon cells.

Unlike conventional monocrystalline solar cells, which are cut from a single piece of silicon, polycrystalline PERC cells are made using a blend of silicon shards. While this produces lower efficiencies than monocrystalline cells, it reduces manufacturing costs. Additionally, a bifacial solar panel’s rear surface allows it to capture sunlight that would otherwise be reflected off the ground or other surfaces.

Thin-film

The process of converting sunlight into electricity using thin-film photovoltaics is much faster than other solar panels and can be easily installed on rooftops. These types of solar panels can also be installed in areas with limited space and are more flexible than crystalline silicon models. They are also lighter, which makes them an excellent choice for roofs that may not be strong enough to support the weight of silicon panels.

In addition, the performance of thin-film solar cells degrades less rapidly than crystalline silicon ones when exposed to higher operating temperatures. They can also absorb more sunlight than mono- or polycrystalline silicon panels.

Shah, who is working with Salamat Ali of Government College University in Lahore, Pakistan, plans to use this technology to create affordable solar power systems that will be able to provide off-grid electrification for remote villages. The project is funded by the U.S. Department of State under Phase 4 of the Science and Technology Cooperation Program.
