1.What’s the difference between mono crystalline solar panel and multi crystalline solar panel?

Monocrystalline solar panels have a higher efficiency rate in generating electricity from light and are a more space-efficient solution. Durable, long living and aesthetically pleasing, these cells are the ideal solution for residential and small commercial rooftop installations.

Multicrystalline solar panels are simpler to produce and offer the most cost-efficient and versatile option. This type of panel is available in a range of sizes and colors, suitable for both residential and larger-scale installations as well as on and off-grid application.

1.How does solar module work?

PV power generation is a method of converting solar energy into electricity via the solar cell. The solar power system generates power via this PV cell. When sunlight is reflected on the cell, the DC current emitted by the cell is converted by an inverter into AC current. By this process, daily electricity demand is met.

The solar power system can be used independently or connected to the public grid. Using the system to generate electricity will reduce expenditure on power consumption and promote application of clean energies.

2.Do we offer customized modules?

Customized module are available to meet the special demands of customers, and are in compliance with the relevant industrial standards and test conditions. During the sales process, our salespersons will inform customers of the basic information of the ordered modules, including mode of installation, conditions of use, and the difference between conventional and customized modules.

3.Will the energy yield be influenced by installation via perforation and welding?

Perforation and welding are not recommended as they may damage the overall structure of the module, to further result in a degradation in mechanical loading capacity during the subsequent services, which may lead to invisible cracks in modules and therefore affect the energy yield.

4.How are the energy yield and installed capacity of modules calculated?

The energy yield of module depends on three factors: solar radiation (H–peak hours), module nameplate power rating (watts) and system efficiency of system (Pr) (generally taken at about 80%), where the overall energy yield is the product of these three factors; energy yield = H x W x Pr. The installed capacity is caculated by multiplying the nameplate power rating of a single module by the total number of modules in the system.

1.Can I only purchase from China?

Our factories are located in China and Thailand, also has warehouses in the United States and EU.

2.What if I have no import experience?

We can provide a door to door service to ship goods directly from China to your location. During the customs clearance period, you are not responsible for the freight logistics, you only need to wait for the receipt of goods.

3.What are the usual terms of payment?

Usually we use 30%T/T and pay the balance before delivery. Of course L/C is also acceptable.

4.How to order?

You just need to leave your contact information on the website, and our professional consultant will contact you.

5.How long can I expect to receive the goods?

Europe takes about 40 days, North America 25 days, Africa 45 days, Southeast Asia and Australia 30 days.

6.Can you help design a whole solar system?

Of course, we have a lot of experience in solar system design, and we can provide all the certifications for grid connection.

7.What’s the MOQ? Is there any discount for bulk purchase?

Under normal circumstances, the minimum order quantity of solar panels is 50KW, and there will be a corresponding discount when it reaches 100kw 500kw 1GW.
