What are Longi Solar Panels?
Longi Solar is a Chinese company specializing in manufacturing high-efficiency monocrystalline solar panels. Monocrystalline panels are made from a single crystal of silicon, which gives them a higher performance and durability than polycrystalline panels, made from multiple silicon fragments.
Longi Solar is the world’s largest producer of monocrystalline silicon wafers, the raw material for making solar cells. Longi Solar has been in the solar industry since 2000 and has been recognized as a Tier One module manufacturer by Bloomberg New Energy Finance, meaning it is financially stable and bankable and manufacturer by PV Evolution Labs.
Longi Solar has also been breaking world records in solar cell efficiency, reaching 25.09% in 2020. Longi Solar offers a range of solar panels for residential, commercial, and industrial applications, with power ratings from 350 watt to 600 watt and efficiency ratings from 20.5% to 23%.
Longi Solar panels come with a standard product warranty of 15 years and a linear power output warranty of 25 years, guaranteeing that the panels will produce at least 83% of their rated power after 25 years.
Why Choose Longi Solar Panels?
You should consider Longi solar panels for your solar system for many reasons. Here are some of the main benefits:
Cost-effectiveness
Longi solar panels are competitively priced in Pakistan, offering a low cost per watt and a high return on investment. According to the latest online prices, Longi solar panel prices in Pakistan range from Rs. 42,300 to Rs. 45,900 for a 540 watt panel, depending on the model and the supplier. It means you can get a high-quality solar panel for Rs. 85 per watt.
Performance
Longi solar panels have a high-efficiency rating, meaning they can produce more electricity from the same amount of sunlight than lower-efficiency panels. With Longi solar panels, you can maximize energy production and reduce dependence on grid electricity or diesel generators.
Reliability
Longi solar panels have a low degradation rate, meaning they can maintain their performance for longer than other panels. Longi uses gallium-doped silicon wafers instead of boron-doped ones, which reduces the risk of light-induced degradation (LID) and potential-induced degradation (PID).
LID and PID cause solar cells to lose their efficiency over time due to light or voltage stress exposure. Longi also uses half-cut cells and multi-busbar technology, which reduce electrical losses and increase the panels' power output.
Sustainability
Longi solar panels are environmentally friendly, using renewable energy from the sun to generate electricity without emitting greenhouse gases or pollutants. By choosing Longi solar panels, you can reduce your carbon footprint and contribute to the fight against climate change. Longi also follows strict environmental standards in its manufacturing process and recycles its waste materials.
How to Choose the Best Solar System for Your Needs?
If you are interested in buying Longi solar panel for your home or business, consider some factors before deciding. Here are some of the steps that you should follow:
Determine your energy consumption
Choose your system type
The next thing you need to do is decide whether you want an off-grid or on-grid system. An off-grid system operates independently from the main grid and relies on batteries or generators for backup power. An on-grid system is connected to the main grid and can sell excess power back to the utility company or use grid power when needed.
The choice depends on your:
- Location
- Budget
- Preference.
Select your panel size and quantity
The final thing you need to do is choose the size and quantity of your Longi solar panel. This depends on your available roof space, energy consumption, and system type. You can use an online calculator or consult a solar expert to help you with this step. As a rule of thumb, you should aim for a panel size that matches your daily peak power demand and a panel quantity that covers at least 80% of your annual energy consumption.
What is the difference between monocrystalline and polycrystalline solar panels?
The difference between monocrystalline and polycrystalline solar panels is mainly in the type of silicon solar cell they use.
Monocrystalline solar panels have solar cells made from a single silicon crystal, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
Monocrystalline solar panels are generally more efficient, durable, and aesthetically pleasing than polycrystalline solar panels. However, they are also more expensive and require more energy to produce. Polycrystalline solar panels are cheaper and easier to manufacture but have lower efficiency, performance, and lifespan than monocrystalline solar panels.
The efficiency of a solar panel is the percentage of sunlight it can convert into electricity. Monocrystalline solar panels have an efficiency rating of 19% to 22%, while polycrystalline solar panels have an efficiency rating of 14% to 17%3. This means that monocrystalline solar panels can produce more electricity from the same amount of sunlight than polycrystalline solar panels.
The performance of a solar panel is how well it can generate electricity under different conditions, such as temperature, shading, and angle. Monocrystalline solar panels perform better than polycrystalline solar panels because they have a lower temperature coefficient and a higher tolerance to partial shading. The temperature coefficient is the rate at which the efficiency of a solar panel decreases as the temperature increases. Monocrystalline solar panels have a temperature coefficient of -0.3% per degree Celsius, while polycrystalline solar panels have a temperature coefficient of -0.45%. This means that monocrystalline solar panels lose less efficiency when the temperature rises than polycrystalline solar panels.
The lifespan of a solar panel is how long it can maintain its performance and output over time. Monocrystalline solar panels have a longer lifespan than polycrystalline solar panels because they have a lower degradation rate and a higher corrosion resistance. The degradation rate is the percentage of power output a solar panel loses yearly. Monocrystalline solar panels have a degradation rate of 0.25% per year, while polycrystalline solar panels have a degradation rate of 0.8% per year. Monocrystalline solar panels can retain more of their original power output after 25 years than polycrystalline solar panels.
The aesthetics of a solar panel is how it looks on your roof or property. Monocrystalline solar panels have a sleeker and more uniform appearance than polycrystalline solar panels because they have black-colored cells with rounded edges.Polycrystalline solar panels have blue-colored cells with square edges showing the silicon fragments' grainy texture. Some people may prefer the look of monocrystalline solar panels over polycrystalline solar panels, while others may not care or notice the difference.
Conclusion
Longi solar panel price in Pakistan is one of the most critical factors when installing a solar system for your home or business. Longi solar panels are among the best in the market, offering high efficiency, reliability, and sustainability at a competitive price.
By choosing Longi solar panels, you can enjoy the benefits of clean energy, save money on your electricity bills, and contribute to a greener future.
