Find answers to common questions about solar energy equipment
selection, maintenance, and usage.

What are the advantages of your company?: We are a professional manufacturer of solar modules, solar storage system, solar inverters, BIPV products and related accessories. We have our own R&D department for new projects and new products development.
And we have obtained the product certificates,IEC61215/IEC61730 and system certificates ISO9001, ISO14001, and ISO45001.

What is a solar panel?: Solar panel (or solar module) is a device which consists of polycrystalline/monocrystalline solar cells, low iron high transmittance anti-reflective tempered glass, encapsulant (like EVA, POE etc...), functional backsheet, PV ribbon, bus bar, junction box and aluminium alloy frame.
Solar panels are a key as well as significant part in a solar power generation system, whose function is to transfer solar energy into electricity to be restored in batteries, or to power the loads.
Solar panels can be classified into following three types :
Polycrystalline silicon solar panel
Monocrystalline silicon solar panel
Amorphous silicon solar panels.
We mainly manufacture monocrystalline silicon solar panels.

What is the difference between polycrystalline and monocrystalline?: Generally, monocrystalline solar panels have a higher efficiency in converting solar energy into electricity, therefore can reduce more space for you when installation.
On the other hand, monocrystalline solar cells are of black color, which makes the whole monocrystalline solar panel more aesthetic. While polycrystalline solar panels are easier to produce with lower cost.
In appearance, polycrystalline solar cells are of blue color and sometimes with snowflake pattern.

Can you do OEM projects?: Yes, we have rich experiences on OEM service. With experienced R&D engineers, we can satisfy our clients' OEM requirements.

What is your warranty policy for solar panels?: We provide 12 years of product quality and process assurance, and 25 years linear power output warranty ( 10 years 90%, 25 years 80%) for all of our solar panel products.

How do you pack the solar panels for overseas shipments?: It depends on the requirements of customers. Normally we pack our solar panels with pallets, and outside with carton box cover for protection.
