Watch high-precision automated wire drawing, continuous annealing, and hot-dip tin plating in action at our Meerut facility.
Founded in 1981 in Meerut, UP, Sumati Renewables (Sumati Electronics Pvt. Ltd.) is a pioneer in solar cell interconnects. Manufactured from 99.99% ETP copper with continuous hot-dip tinning, our products power top solar module makers worldwide.
Trusted by 100+ global solar module manufacturers across India, Europe, and Asia.
Dual-axis in-line laser micrometers guaranteeing ±0.005mm thickness accuracy.
Over four decades of metallurgical mastery in silver and tinned copper wire production.
Engineered to minimize internal series resistance, eliminate micro-cracking, and maximize power conversion efficiency.
High-purity TU1 copper (99.99%) interconnect ribbon with hot-dip tinning for low soldering temperature.
Patented micro-grooved triangular prism ribbon redirecting sunlight into cell substrate via total internal reflection.
Precision micro round tinned copper wire (0.22mm - 0.40mm) engineered for 9BB to 16BB solar modules.
Heavy-duty flexible tinned copper lead wire for string connections and junction box lead-outs.
Precision tinned flat copper busbar delivering high current carrying capacity with zero burr edges.
