LONGi is the best option if you want a solar panel to provide energy for your house. Its performance as well as cost is comparable to premium brands like SunPower/Maxeon or Panasonic. LONGi solar panel panels are cheaper than their higher-end counterparts and are made in China.
PERC
LONGi's Solar Hi-MO 4 range may be a good option if you want a high-efficiency panel. This panel range is based on monocrystalline PERC semi-cut cell technology. The Hi-MO 4 range features panels in 60-cell and 66-cell formats. These panels are also built with gallium-doped silicon to reduce light-induced degradation. These panels are less susceptible to light-induced degradation than N-type cells. They will still retain approximately 11% to 12% their power after 25 year.
Longi panels' PERC technology is among the most effective on the market. The high-efficiency cells convert more sunlight into electricity. Longi modules may be mounted both on rooftops and on ground-mounted polemount systems. This makes them an excellent choice for a variety of site conditions.
Half-cut
Longi-cut half-cut panels are more affordable than traditional solar panels. These modules use newer technology to deliver high efficiency, including gallium-doped silicon, which helps reduce light-induced degradation. This resulted in a lower annual degradation rate, and a higher power output in times of shade. These panels are ideal for commercial and utility-scale installations and are available in various cell count sizes.
In addition, this type of panel is less prone to breakage. The method of assembling half-cut solar panels involves cutting the cells in half. This decreases power loss up four-fold and increases efficiency. Reduced resistance in busbars results in increased efficiency. A module can experience a 2% increase in power.
bifacial
Longi bifacial solar panels have glass covers on both sides of the panels, enabling you to install them either horizontally or vertically. By reflecting the sun's energy back onto the panels, you can maximize the sun’s energy production. Bifacial panels are also stronger and more durable than traditional solar panels. They are also more efficient in converting sunlight into electricity.
Bifacial panels are an excellent choice for those who are concerned about aesthetics. These panels can be mounted on your roof or ground, and will blend well into the overall look of your home. These panels can also be used in areas where there is heavy snow or a ground-mount system.
Performance warranty
Longi's solar panels come with a 25 year performance warranty. This warranty period is longer than average. After this time, many solar manufacturers will only offer a seventy-five percent or 80% guarantee. This guarantee is impressive, especially when you consider the price. Longi's warranty period is based upon the company's constant financial stability.
To claim your warranty, contact the original installer who installed your solar system. This individual is the best qualified to determine potential issues. They will help you to file a claim. If you are not able to locate the original installer, you may submit your warranty claim online. You can also reach out to Longi distributors.
Cost
LONGi is a Chinese firm that produces photovoltaic and solar power panels. LONGi, formerly Xi'an Longi Silicon Materials Corporation is a major supplier of photovoltaic and solar power modules. The company is also involved in the development of solar power projects within China.
Panels from the company are affordable without sacrificing on efficiency. The panels have high wattage modules which help reduce installation cost and material costs.
