Luan 420W solar panel known for their high efficiency and sleek appearance, these panels are made from single-crystal silicon. They perform well in low-light conditions and have a long lifespa.
ZHU JKL108-B-(420-440)NH Solar Panel utilizes monocrystalline silicon solar panels, applying Topcon solar cell technology, and single-sided design, which can meet the installation requirements of most environments while ensuring high efficiency, and at the same time, lower costs for use, installation and maintenance.

Most conventional solar panels are designed for single-sided power generation, where photovoltaic conversion is performed by absorbing solar radiation on the front side, and the back side is usually closed and has a protective material, such as a backsheet.
Single-sided power generation solar panels have three relative advantages:
1. Lower cost: Due to the simpler structure and less material usage, the manufacturing cost of single-sided panels is usually lower than that of double-sided panels, and the installation and maintenance costs are also relatively low.
2. Mature technology: the production technology of single-sided battery panels has been developed over the years, the process is very mature, high reliability, and widely used worldwide.
3. Suitable for all kinds of installation scenarios: single-sided panels are widely used in rooftop installations and ground-level power plants, and are not restricted by reflected light conditions.
1. Residential and commercial rooftop photovoltaic systems: Since rooftop installation usually limits the exposure of the back side of the solar panel, single-sided panels are better applied and less costly.
2. Traditional ground-mounted power plants: In areas where the ground does not reflect much light, single-sided panels are still the more economical choice.
3. Mobile applications or small off-grid systems: Due to their simple structure and light weight, single-sided panels are suitable for installation in small mobile power systems or off-grid PV systems in remote areas.
