We are a leading design and manufacturing company of world-class solar products for commercial and residential use, including 3W to 295 W solar panels.
Our products and manufacturing processes are fully compliant with product safety and EMS requirements, including TUV/IEC61215 & 61730, CSA/UL1703,MCS ,CE and UKAS. Additionally, we have implemented best practices to protect the environment and conserve energy.
Topsun main product is solar photovoltaic panel. Company manufacture solar panel ranges from 10wp to 260wp base on mono crystalline & multi crystalline high efficient solar cell.
1. High power module with precisely manufactured to achieve top most module conversion efficiency in the industries.
2. Ar coated cell surface to reduce the reflection of sunlight and bsf (back surface field) structure to improve cell conversion efficiency.
3. Due to use of high quality and iec certified raw materials from international reputed brands we assure our modules reliability, durability and consistency when exposed to real usage.
4. Rugged double-coated aluminum-alloy frame for longevity in adverse conditions.
5. Every batch of cells is individually inspected for optical & electrical parameters to ensure aesthetic appeal & consistent performance when the module is applied to an array.
6. Manufactured under iso 9001:2000 qms
