King kong NC Series Solar Panels 300W 20V PERC 260302
Product description
The Kingkong EC series consists of standard monocrystalline photovoltaic modules featuring TOPCON solar cells, which increase power output per unit area. Built with tempered glass and an aluminum alloy frame, these durable modules offer strong mechanical performance and operate stably in diverse environments with high efficiency. They also show minimal power degradation—retaining at least 90% of initial output after 10 years and 80% after 20 years. With excellent reliability and long-term performance, they are ideal for a wide range of applications.

Product Expansion
As the global energy structure accelerates its transformation towards cleanliness and low carbonization, the photovoltaic (PV) industry, as the core pillar of renewable energy, is entering a critical cycle of technological iteration. TOPCon (Tunneling Oxide Passivated Contact) technology has become the absolute mainstream in the photovoltaic cell field due to its comprehensive advantages of high efficiency, stability and economy. According to TrendForce's forecast, by the end of 2025, the TOPCon cell production capacity will reach about 967GW, accounting for 83% of the global total cell production capacity, with an actual output of about 580GW. As of March 2025, the proportion of TOPCon in China's photovoltaic cell output has reached as high as 86.9%, far exceeding other technical routes. We are deeply engaged in the photovoltaic field, focusing on the R&D, production and customization of TOPCon non-standard solar panels. Relying on the latest industry technological achievements after June 2025, we break the limitations of standardized products and provide tailor-made photovoltaic solutions for global customers with different scenarios and needs.
