Heterojunction solar module (HJT)

HJT (Heterojunction) solar panels offer several advantages compared to traditional solar panel technologies.

Here are some of the advantages of HJT solar panels:

High Efficiency: HJT solar panels have a high conversion efficiency, meaning they can convert a larger portion of sunlight into electricity. The use of multiple semiconductor layers with different electronic properties allows for improved light absorption and enhanced current-voltage characteristics, resulting in higher overall efficiency.
Better Performance in High Temperatures: HJT solar panels exhibit better performance in high-temperature conditions compared to some other solar panel technologies. They are less affected by the heat and show reduced efficiency egradation,
making them suitable for regions with high ambient temperatures or strong temperature variations.
Low Light Performance: HJT solar panels perform well under low light conditions, including cloudy or shaded environments. They have a higher sensitivity to weak light, allowing them to generate electricity even in sub-optimal lighting conditions.
Long-Term Reliability: HJT solar panels are known for their long lifespan and durability. They demonstrate excellent stability over time, with minimal degradation in performance. This longevity makes them a reliable choice for long-term solar installations.
Aesthetically Pleasing: HJT solar panels often feature a sleek and aesthetically pleasing design. They can have a uniform and visually appealing appearance due to the use of thin, transparent conductive layers. This makes them suitable for architectural applications where the visual aspect is important. Overall, HJT solar panels offer advantages such as high efficiency, better performance in low light conditions, enhanced performance in high temperatures, long-term reliability, and an appealing design. These features make HJT panels a promising choice for various solar energy applications.

The Technology of Flexible Cylindrical solar module

Flexible Cylindrical solar module with 24% efficiency Hetro Junction solar cells with unique super wire flexible connection technology

High Efficiency Light Weight Wrappable HJT Solar Panel

High efficiency Hetro-junction Solar Cells (efficiency>24%) are laminated inside with excellent weak-light performance and superior Power Temprature co-efficient, which enable the solar panel to achieve 5%-10% more power.

Unique super power flexible connection technology ensures an excellent ability to resist cell cracks and impact force, even under extreme conditions, solar cells and the panel still generate as long as they are not destructively damaged

The Unique Design of 6-10 circuits in parallel connection ensures a semi-cylinder area always faced the sun to achieve stable voltage and high-efficiency power storage.

The solar panels are applicable for poles with diameters>168.3mm. Each flexible HJT solar panel is 1.33 meters long and its rated VMP is 17.7V or 34V. One or more lengths can be installed on a pole to make the fullest use of the pole’s lenght to achieve the highest power.

FFC/PET/FFC thin film (Transparency>90%) is laminated with good abilities to resist UV, low and high temperature, heat, humidity and salt spray. Vertical instalation can protect the solar panel from dusts, storms, sand and snows and reduce solar panel’s cleaning frequency.

A boost constant current charge controller integrated with an LED driver is a combination of two essential functions in one circuit. Let’s break down each part:

Boost Constant Current Charge Controller: This component is responsible for managing the charging process of a battery or energy storage system. It takes the variable voltage from a power source (like a solar panel or another power supply) and boosts it to a higher level while maintaining a constant current flow during the charging process. This ensures that the battery is charged efficiently and safely.
LED Driver: An LED driver is a device that regulates the current and voltage supplied to LEDs, ensuring they receive the appropriate electrical parameters for optimal performance and longevity. LED drivers are crucial for maintaining a consistent and stable current flow to the LEDs, preventing overcurrent or voltage spikes that could damage the LEDs. When you integrate a boost constant current charge controller with an LED driver, you essentially combine the functionalities of charging a battery and driving LEDs into one integrated circuit. This integration is commonly used in solar-powered LED lighting systems, where the solar panel charges the battery during the day through the boost constant current charge controller. Then, during the night or when needed, the LED driver utilizes the stored energy in the battery to power the LEDs, providing efficient and reliable illumination. This integrated approach is convenient and space-saving, making it a popular choice for solarpowered LED applications, especially in outdoor lighting and remote areas where a reliable power source is crucial.
