TW Solar is a branch of the Chinese Tongwei Group, which has been a leading player in the photovoltaics industry since 2006.

Based in Chendu, China, TW Solar is one of the world’s largest manufacturers of both its own solar modules and solar cells used by other companies. In the first half of 2024, TW Solar shipped 18.7GW of solar modules (7th largest) while also shipping the among most solar cells of any company in the world.

TW Solar is making highly efficient solar modules for the mass market with the latest improvements in N-type TOPCon cells in its TNC2.0 range, which promise module efficiency exceeding 24%.

High bifacial solar cells gains, the equal of the best available today, can further increase the power gains and financial returns of TW Solar modules, particularly in commercial and industrial applications.

TW Solar stays at the forefront of the latest technologies in solar PV, developing the first large-scale production line of HJT cells and industrialising the manufacturing of N-type TOPCon cells to make high efficiency modules more affordable.

TW Solar is also investing in the research and development of perovskite solar cells to be ready to jump on the next big leap forward in solar technology.

TW Solar modules are manufactured with 2mm temperature glass covers on both the front and rear sides, offering improved protection against damp, overheating, and microcracking from environmental stresses.

The thicker glass also offers better kinetic protection against impacts compared with thinner 1.6mm covers.

Looking to the future, the upcoming THC range promises to bring annual degradation levels down to 0.375% per annum, below the 4% we see in the best modules today. This promises to give customers better returns from their solar panels over a 30 year lifespan.
