XRSOLAR WHOLESALE SOLAR MODULES
offers a variety of modules and solutions to fit your project needs.
Solar Module Categories
TOPCON Solar Module
XRSOLAR N-Type Solar Module use N-type solar cell. TOPCon takes the passivation concept a step further by adding an ultra-thin tunnel oxide layer and a thin layer of polysilicon to the rear of the cell.The efficieny significantly higher than PERC, with typical commercial efficiencies reaching 23%-25%.
KEY Performance : Better temperature coefficient; Lower degradation; Better low-light performance.
PERC Solar Module
XRSOLAR P-Type Solar Module use PERC solar cell. A PERC solar cell adds a dielectric passivation layer to the back of a standard solar cell. This extra layer has two primary functions:
1.Reflects unabsorbed light – increases the amount of energy absorbed.
2.Reduces electron recombination-maintain a higher voltage and current.
BC Solar Module
XRSOLAR BC SOLAR Module is By moving all the contacts to the back, the entire front surface of the solar cell is free and unobstructed, allowing it to absorb the maximum amount of sunlight. Advantages of BC Solar module: Highest Efficiency and Superior Aesthetics, Excellent Low-Light Performance. Best for RVs, boats, or small, high-value rooftops.

Frequently Asked Questions (FAQ) of Solar Module
What is the efficiency of a solar module?
Solar module efficiency is the percentage of sunlight that a panel can convert into electricity. Most modern residential panels have efficiencies ranging from 18% to over 24%. Higher efficiency means the panel can generate more power from the same amount of sunlight, which is important for limited roof space
How is a solar module’s power output rated?
The power output is measured in Watts (W), which indicates the maximum power a module can produce under Standard Test Conditions (STC). These conditions are a controlled environment with a specific temperature () and solar irradiance ().
How long do solar modules last?
Most solar modules have a lifespan of 25 to 30 years or more. Manufacturers typically provide two types of warranties:
Product Warranty: Covers defects in manufacturing, materials, or workmanship, usually for 10-12 years.
Performance Warranty: Guarantees that the module’s power output will not fall below a certain percentage (e.g., 80% to 85%) of its original rating over a period of 25 years.
Do solar modules work on cloudy or rainy days?
Yes, but they are less efficient. Solar modules need daylight, not necessarily direct sunlight. On a cloudy day, they can still produce 10-25% of their typical output.
Are solar modules affected by heat?
Yes. Solar module efficiency decreases as the temperature of the module increases. This is measured by the temperature coefficient, which tells you how much the output decreases for every increase above . A lower temperature coefficient is better.
Do solar modules need maintenance?
Solar modules are generally low-maintenance. Occasional cleaning (1-2 times a year) to remove dust, dirt, and debris is recommended to ensure optimal performance. In most cases, rain will do a sufficient job of cleaning them.
Can solar modules be recycled?
Yes, most components of a solar module can be recycled. The aluminum frame, glass, copper wiring, and a significant portion of the silicon can all be recovered and reused. Recycling processes are becoming more widespread as solar panels reach their end-of-life.
What is the difference between a solar cell, solar module, solar panel, and a solar array?
Solar Cell: The smallest component that converts sunlight into electricity.
Solar Module: A group of solar cells wired together, forming a single, self-contained unit.
Solar Panel: Often used interchangeably with “solar module,” but can also refer to a single module.
Solar Array: A complete system of multiple solar modules, mounted together and connected to an inverter and other electrical components.
