5.FAQ of Solar Module

1. Q: Do you have your own factory?

    A: Yes, we have. Our factory located in Jiangyin city, jiangsu province.

2. Q: How can I visit your factory?
    A: Before you take off from your country, please let us know. We will show you the way,or arrange time to pick you up if possible.
3. Q: Could you print our company LOGO on the nameplate and package?
    A: Yes, we can do that.
4. Q: Do you accept custom design on size?
    A: Yes, if the size is reasonable.

 

Q:Can solar panels be used in areas with high pollution levels?
Yes, solar panels can be used in areas with high pollution levels. While pollution may slightly reduce the efficiency of solar panels by blocking some sunlight, they can still generate electricity. In fact, using solar panels in such areas can be beneficial as they provide a clean and renewable energy source, helping to reduce reliance on polluting fossil fuels.
Q:Can solar panels be installed in urban areas?
Yes, solar panels can be installed in urban areas. In fact, urban areas provide great opportunities for solar panel installations due to the abundance of rooftop space and potential to generate clean energy in densely populated areas.
Q:How do solar panels interact with the electrical grid?
Solar panels interact with the electrical grid through a process called net metering. When solar panels produce more electricity than is being used, the excess power is sent back to the grid, and the owner is credited for the energy produced. Conversely, when solar panels don't generate enough electricity, energy is pulled from the grid to meet the demand. This bidirectional flow enables solar panel owners to offset their energy usage and contribute to the overall energy supply.
Q:how to use a motor with solar panel
A solar panel cannot operate a motor by itself. A typical system operates like this: The solar panel is connected to a charge controller which is connected to a battery which is connected to a motor controller which is connected to the motor. All these components must be compatible with each other. So,in other words, you can't run just any old motor with a solar panel.You can buy a system like an electric gate opener which is solar powered.
Q:Can solar panels be installed on a data center or technology facility?
Yes, solar panels can be installed on a data center or technology facility. In fact, many data centers and technology facilities are increasingly adopting solar power as a way to reduce their carbon footprint and lower energy costs. Solar panels can be installed on the rooftops or open spaces surrounding these facilities to generate clean, renewable energy that can be used to power their operations. Additionally, the excess energy produced by the solar panels can even be fed back into the grid, providing an additional source of revenue for the facility.
Q:please help me
Hint: It's behind the foreground.
Q:I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:How do solar panels impact the local economy?
Solar panels can have a positive impact on the local economy in several ways. Firstly, the installation and maintenance of solar panels create jobs, boosting employment opportunities in the area. Additionally, the use of solar energy reduces dependency on traditional energy sources, which can lead to lower energy costs for businesses and residents, freeing up more money to be spent locally. Furthermore, solar panel installations often require local partnerships and suppliers, supporting local businesses and stimulating economic growth. Ultimately, the adoption of solar panels contributes to a more sustainable and resilient local economy.
Q:What is the impact of roof pitch on solar panels' efficiency?
The impact of roof pitch on solar panels' efficiency is significant. The pitch, or angle, of a roof determines how much direct sunlight the panels receive and how effectively they can convert that sunlight into electricity. In general, a roof with a steeper pitch allows for better solar panel performance as it maximizes exposure to sunlight and minimizes shading. However, if the roof pitch is too steep, it can increase wind resistance and make installation more challenging. Therefore, it is crucial to find the optimal balance between roof pitch and solar panel efficiency to ensure optimal energy production.
Q:How does the size of a solar panel affect its performance?
The size of a solar panel directly affects its performance as it determines the amount of sunlight it can capture and convert into electricity. Generally, larger solar panels have more surface area to absorb sunlight, resulting in higher power output. A larger panel can generate more electricity, making it more efficient and productive than a smaller one. Additionally, larger panels often have more individual solar cells, which further enhances their performance and efficiency.
