Questions and Answers
Q:
Are there any instances of breakage, scratches, spontaneous explosions, or bubbles on the modules?
A:

Throughout the entire lifecycle, solar modules may exhibit various abnormal issues, stemming from the manufacturing, transportation, installation, and operational phases. However, by procuring RedSolar products through legitimate channels and following the installation and maintenance guidelines provided by Red Solar, these issues can be effectively avoided. They will not have any impact on the reliability or power generation output of the solar power station.


Q:
What is causing the instability in the current and voltage of the power station, and will it have any impact on the power generation of the station?
A:

The current and voltage of a solar power station are related to temperature and sunlight. Due to the constant variations in temperature and sunlight, voltage and current exhibit fluctuations (higher temperatures result in lower voltage but higher current, while good sunlight leads to higher values for both). The operational temperature range for the modules is -40°C to 85°C, so temperature changes do not have a significant impact on the power generation of the station.


Q:
How do RedSolar's high-efficiency modules contribute to achieving 'zero carbon and carbon negative' throughout the entire lifecycle of power plants?
A:

Redsolar modules build a green and low-carbon chain from raw materials, production to terminal applications, thereby reducing the carbon emissions of the modules themselves.

 

Simultaneously, Redsolar modules, employing advanced module technology and rigorously selected Bill of Materials (BOM) materials, can effectively increase the power generation of the project, ensuring a higher emission reduction throughout the entire lifecycle of the power station.


Q:
What types of rooftops are Redsolar modules suitable for?
A:

Redsolar modules are suitable for a wide range of roof types, including flat/sloped roofs and color steel tile roofs, among others. For actual projects, a rooftop survey is necessary to determine the structure and load-bearing capacity, followed by the design of module layout.


Q:
What are the electrical performance parameters of PV modules?
A:

The electrical performance parameters of photovoltaic modules include open-circuit voltage (Voc), short-circuit current (Isc), maximum voltage (Um),maximum current (Im), and maximum output power (Pm).

 

1. When the positive and negative electrodes of the modules are short-circuited (U=0), the current at this time is the short-circuit current. When the positive and negative electrodes of the modules are not connected to the load, the voltage between the positive and negative electrodes of the modules is the open-circuit voltage.

2.  The maximum output power depends on solar irradiance, spectral distribution, operating temperature, and load size. Testing is typically conducted under Standard Test Conditions (STC), which refer to AM1.5 spectrum, an incident irradiance of 1000W/m2, and module temperature of 25℃.

 

3. The operating voltage is the voltage corresponding to the maximum power point, and the operating current is the current corresponding to the maximum power point.

Q:
How do we increase the power generation of modules in a distributed rooftop solar system?
A:

Rooftop photovoltaic modules require regular cleaning.

 

1. Regularly inspect the cleanliness of the module surface (once per quarter), and clean with clear water, ensuring the surface is thoroughly clean during the cleaning process to prevent residual dirt from obstructing and causing hotspots on the modules.

 

2. In order to avoid electric shock injury and possible damage to the modules when wiping them under high temperature and strong sunlight, it is advisable to clean the modules in the morning or evening without sunlight.

 

3. Ensure that there are no tall weeds, trees, or structures higher than the modules on the east, southeast, south, southwest, and west sides as much as possible. Trim any vegetation exceeding the height of the modules promptly to avoid shading and impacting the power generation capacity of the components.

How do I maintain my photovoltaic power station in summer?

1. Maintain ventilation, regularly check heat dissipation around the inverter to see if the air circulates normally, regularly clean the occlusions on the modules, regularly check if the brackets and module fasteners are loose, and check if the cables are exposed.


2. Ensure that there are no weeds, fallen leaves, or birds around the power station. Do not dry crops and hang out the clothes, etc. on the photovoltaic modules, which not only affects power generation, but also causes thermal spot effects of the modules, triggering safety hazards.


3. It is prohibited to water the modules for cooling during high temperature periods. Although this method has a cooling effect, if your power station is not equipped with proper waterproof protection when designed and installed, there may be a risk of electric shock. In addition, watering for cooling is equivalent to an artificial sunny rain, which will also reduce the power generation of the power station.


How do we choose monofacial and bifacial modules?

Considering the existing price gap between monofacial and bifacial modules, the unobstructed exposure of the back surface in bifacial modules substantially enhances power generation. Furthermore, the glass/glass sealing structure of bifacial modules exhibits superior resistance to environmental factors like water vapor and salt mist. In scenarios involving distributed or tiled installations in mountainous areas, monofacial modules are more suitable.


How does Redsolar ensure the supply of production capacity?

Redsolar has achieved a module production capacity of 10 GW, and its integrated production capacity layout is designed to fully guarantee module supply. The quality and reliability of Redsolar modules have earned recognition from customers worldwide.
