Q1: Why buy Materials & Equipment from OKorder.com?
A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.
Q2: What is a solar PV module?
A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).
Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?
A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.
Q4: What is the typical service life of a solar PV module?
A: The typical life of a PV module is 25 years. However, superior quality PV modules boast service lives up to 35-40 years (electrical generating capacity is often reduced, however by that point).
Q5: What certifications do you have?
A: We are specialized in the photovoltaic field, with a focus on solar cells, modules and photovoltaic power generation systems. We employ advanced monocrystalline and polycrystalline silicon solar cell manufacturing equipment, producing highly efficient and reliable products sold in Europe, the Americas and Australia. Our company has passed ISO9001 quality management system certification, and our products have obtained TUV-IEC, CE and ISO certification.
