More energy from the same roof area – this is why LONGi’s back contact technology is worth it⚡️

🌞 What does LONGi back contact technology offer from a technical perspective?

The performance gain of back contact panels comes not only from their elegant appearance but from their optimized internal cell design. By eliminating front-side busbars, the active light-absorbing surface increases, optical losses are reduced, and overall energy conversion efficiency improves.

HPBC (Hybrid Passivated Back Contact) technology is especially advantageous in installations with limited roof space where maximum yield is required. LONGi back contact panels can produce more energy within the same module footprint, maintain stable output under lower irradiance, and reduce shading-related losses.

⚫ Truly black – not “almost”

One of the strongest visual advantages of LONGi back contact panels is their uniform deep-black appearance. Since there are no visible front-side silver busbars, the entire surface remains sleek and seamless, ideal for design-conscious projects. On a building façade, these panels provide a clearly superior aesthetic result.

🏦 Why does AAA+ bankability matter?

A solar system is a 20–25 year investment. Your customers expect guarantees that last decades.

LONGi’s AAA+ rating means its financial stability is recognized by top independent institutions worldwide. This is your assurance that LONGi will still be around when the warranty ends and that support will be available. It’s peace of mind not only for the end-user, but also for you as an installer.
