FAQ
what is the difference of your product's surface treatment between salt damaged areas and ordinary areas?
The average anodized thickness of solar mounting structure in ordinary areas is 10um, the average galvanized thickness of ground screw pile is 80um.But the average anodized thickness of solar mounting structure in salt damaged areas is 18um, and the average galvanized thickness of ground screw pile is 100um. In addition, the bolt material we used in ordinary areas is SUS304, and the bolt material we used in salt damaged areas is SUS316.

How long does it take from receiving the order to shipping?
Basic aluminum solar bracket products take about 10-15 days, other special materials need to confirm the delivery time of each order.
The current inspection requirements for large-scale projects in Japan are very strict. If we have any question during the inspection by the Ministry of Economy, Trade and Industry, could you help prov
Our company also has corresponding experience in large-scale projects before. We can provide calculation report and relevant information according to the requirements of the Ministry of Economy, Trade and Industry. We will do our best to respond to questions.
Do I need to worry about solar panels in the snow?
Snow and ice are a reality of installing solar arrays in the Northeast and we design our systems to withstand the toughest weather we get. The reality is, after a snowstorm, your solar panels will be covered in snow. Don’t panic! Usually theymelton the next sunny day. On an annual basis, the amount of energy production loss due to snow is fairly minor.
Will the solar array put holes in my roof, or be too heavy?
The solar panels will be mounted on a purpose-built aluminum rail system. For examples, if on a standing seam metal roof, these accessories are made directly to the standing seams, with no roof penetrations. We guarantee all roof work will be free from leaks. As for the weight of the array, it is less than 5 pounds per square foot, so a typically framed roof is more than adequate to carry the weight.
What are the benefits of using Solar ?
1. Reduce Energy Bills 2. Safe Investment, High Returns 3.Minimal Maintenance 4.Environment Friendly. Solar is like saving for retirement, the sooner you start doing it, the better.
What is the process to get my system plan permitted?
Because solar permitting is handled by the local authority, the permitting process will vary based on where you live. Most localities require installers to file for a solar permit, the stipulations of which differ by jurisdiction. Solar permits are in place to ensure that your system is installed safely and follows local code.
On what roof materials can solar mountings be installed?
usually it can be installed on almost any kind of roof material and almost any roof structure (flat roof, inclined roof, tin roof or tile roof etc.). Our team will work out the best structure design for your roof accordingly.
Can you provide the strength calculation of mounting system and foundation?
Yes, but the strength calculation of the foundation (Pile) needs to provide land survey report and we will calculate the strength according to the land N value and nature(clay or sandy soil).
What information should I provide when I quest for solar structure quote?
Before designing, we need to confirm dimension,output power and layout of solar panel used in the project,the maximum wind speed and snow load in this area. If it is a ground project,then it needs to confirm the ground is sloping or flat; If it is a roof project, the roof height and roof structure need to be confirmed. You had better be able to provide detailed CAD drawings of roof building and so on. Other information need analyze according to the actual situation.
What material is used for flat roof?
Modern flat roofs solar mountings can use Aluminum, SUS304, EPDM synthetic rubber, etc. There are many types of solutions for your rooftop project in WINTOP. There's always a right one for you.
In winter, when the weather is cold, will the power generation system run out of power?
The power generation of PV system is indeed affected by temperature, but the influence is very small. The factors that directly affect the power generation are the irradiation intensity and sunshine as well as the operating temperature of solar panels. In winter, the temperature is lower and the sunshine time is shorter, so the electricity generation is less than that in summer, which is also a normal phenomenon.
What are the requirements of the installation of rooftop solar system for the surrounding environment?
If there is a large dust pollution source around the PV power generation system, large sand, heavy smoke and so on affect the use of light, then it will lead to a decrease in power generation.
What is the maximum wind resistance that your solar structure can withstand?
Usually ,within 60m/s wind speed is no problem for our solar structure.
Have your products ever had quality problems or less delivery?
strict quality and quantity inspection will be carried out before shipment, we usually provide spare parts for small components,such like screws,mid clamp, end clamp. If there is a lack of long parts, air transportation will be arranged
What materials of your bolt and screw?
It is usually SUS304, and some projects require SUS410.
What conditions need to be confirmed before the solar mounting design?
Before the design, it is necessary to determine the size and capacity of the panel used in the case, the arrangement of the panel, the maximum wind speed in the region, and the snow load. If it is a ground case, it is also necessary
Can you provide strength calculation report?
Yes.
How can I trust your company?
We specialize in solar installation business for 6 years, our office and factory are located in Xiamen City, Fujian Province, you are welcome to visit in any way. After the production of the product is completed, we will send the pictures.

Yes, we do OEM, We produce according to customer's product needs to meet the customer's products market.
Can you provide projects design drawings?
Yes, after providing relevant project information, we will provide free design drawings to customers.
What test reports and certifications does the company's products have?
SGS tensile test report, Salt spray test and IOS certification
Could I get the quotation without the confirmed array drawing?
Yes, we could recommend the array and send you the quotation, but including the other necessary conditions, pls also provide us the specific size of the site in CAD and the latitude and longitude for us to count shadows.Yes, we co.
Whats the advantage of your aluminum solar mounting?
1. About the weight, our aluminum structure is much lighter, which is only about one third of the weight comparing to the steel structure. 2.About the working time, aluminum brackets can reach more than 25 years, while the service life of steel brackets is only about 10 years at most. 3.About the construction period, lightweight of the aluminum brackets is more easily to construct, even only one person could finish the assembling 100%. That means shortening the construction period and reducing the construction cost. 4.About the corrosion, aluminum brackets have better corrosion resistance. Considering so many points, our aluminum mountings can also guarantee 10 years warranty.
Aluminum Structure VS Posmac
In south Korea the unit price of Pomac should be a little lower than aluminum structures.But from the perspective of construction convenience ,aluminum structures are more conducive to construction,Shorter construction period can.
