Trina announces new dual-glass panel with 22.5% efficiency for C&I settings


China-headquartered manufacturing heavyweight Trina Solar said the new Vertex S+ NEG18R.28 module is currently being reviewed by the Clean Energy Council (CEC) with Trina anticipating the mono-facial dual-glass panel will be available in Australia for purchase in Q1 of 2024.

Trina said the 1.6 mm x 1.6 mm dual-glass solar panels features high-transmission anti-reflective (AR) coated heat-strengthened glass on the front and heat-strengthened glass on the reverse which deliver higher power generation and improved reliability.

The Vertex S+ NEG18R.28 modules yield a maximum power output of 505 W with an efficiency of 22.5%, a performance Trina attributes in part to the N-type technology which the company said ensures “a longer lifespan, less light-induced degradation, and delivers a higher conversion efficiency than P-type panels.”

Trina said the panels have ultra-low degradation rates, including a 1% first year and 0.4% annual degradation.

The panels measure 1,961 mm x 1,134 mm with a width of 30 mm and weigh 23.5 kg, dimensions that Trina said make installation straight-forward while ensuring the panels are robust enough for larger-scale commercial installation.

“Lighter-weight panels make installation in hard-to-reach spaces easier and the panels may also suit older buildings whose roofs were not originally designed to hold extra load long-term,” the company said.

Trina also said the design of the panels provides optimised energy production under inter-row shading conditions, which can be prevalent in commercial and industrial installations.

The NEG18R.28 panels include potential induced degradation (PID) resistance to reduce deterioration due to unwanted charge carrier movements, have increased crack and scratch resistance, meet IEC fire ratings (Class A+C), and have passed 35 mm hail tests.

The panels are backed by a 25-year product warranty and 30-year performance warranty.
