Technical Features of Photovoltaic Modules

The efficiency and performance of photovoltaic modules are influenced by various technical aspects. These factors impact the overall energy output and lifespan of the system. Key technical characteristics include cell technology, power output, size, and warranty. Let’s explore these in more detail.

Feature	Description
Cell Technology	Determines the module’s efficiency and cost. Common types include monocrystalline, polycrystalline, PERC, TOPCon, and HJT.
Power Output (Wp)	Indicates the maximum electrical power the module can generate under standard test conditions (STC). Higher wattage means more power.
Module Size	Affects installation design and space requirements. Common sizes are defined by the number of cells used (e.g., 60-cell, 72-cell, 120-cell).
Temperature Coefficient	Measures the change in power output with temperature variations. Lower coefficients indicate better performance in hot climates.
Warranty	Typically includes a product warranty covering manufacturing defects and a performance warranty guaranteeing power output over time.
Bifaciality	Refers to modules that generate electricity from both the front and rear surfaces, increasing power output.
Number of Busbars	Affects current distribution and efficiency. Modules with more busbars (e.g., 9BB, 12BB) generally have higher efficiency.

Types of Photovoltaic Modules

The Chinese PV market offers a wide array of module types, each with its own strengths and weaknesses. The choice depends on factors like budget, climate, and application.

Module Type	Advantages	Disadvantages
Monocrystalline	High efficiency, aesthetically pleasing, good performance in high temperatures.	Higher cost compared to polycrystalline modules.
Polycrystalline	Lower cost, readily available.	Lower efficiency compared to monocrystalline, less efficient in high heat.
PERC (Passivated Emitter and Rear Cell)	Improved efficiency compared to standard polycrystalline.	Slightly higher cost than standard polycrystalline.
TOPCon (Tunnel Oxide Passivated Contact)	Very high efficiency, good low-light performance.	Relatively new technology, potentially higher cost.
HJT (Heterojunction)	Extremely high efficiency, excellent temperature coefficient.	Relatively high cost, limited availability.
Bifacial Modules	Increased power generation due to light absorption from both sides.	Higher cost, requires specific mounting and shading considerations.
Half-Cut Modules	Reduced losses from shading, improved performance.	Slightly higher cost.
