ZHEJIANG RDM TECHNOLOGY Co., Ltd. is a professional manufacture to do the solar panel, solar module. We can do all kinds of monocrystalline / polycrystalline(5W-300W) silicon solar modules according to our customer's different requirement. Our company has a productivity of 100MW units in 2010.
We have been trying to become the best PV products manufacturers in China.
We guarantee that our solar module have a plus tolerance 0-3%. We also provide OEM for other photovoltaic module.
The reason why RDM photovoltaic panel is authorized and chosen by the customers is its long-term high stability and low power attenuation. Its main features include:
1) It has passed the IEC 5400PA mechanical-load test and is able to withstand the worst, high load working environment;
2) 18 core quality monitoring points, 30 important quality monitoring points, and 100% of the current and voltage test ensure that it meets the power requirements of the power tolerance 0 ~ +3%;
3) It has passed a number of international certifications and tests (TUV, IEC61215&IEC61730, CE, CEC, RoHS, ISO)
