The Hitouch 5B series is Hanersun's answer for investors who expect both high performance and aesthetics worthy of prestige projects. At the heart of the module lies back contact (BC) cell technology, where all electrical contacts are moved to the rear of the cell - leaving the front surface free of visible grids and busbars, which translates into maximum utilization of incident light and a smooth, uniform panel appearance. This makes it an ideal solution for installations where visual impact matters just as much as energy output - facades, street-visible rooftops, or prestigious commercial buildings. The panel features a bifacial design with a transparent back glass, allowing it to capture additional energy from reflected light and boosting overall annual yield. Thanks to optimized electrical design and lower operating current, the module offers reduced hot-spot and micro-crack risk, resulting in greater durability in demanding environments - salt exposure, humidity, high temperatures, or ammonia contact. The series is backed by a warranty insured by Munich RE, giving investors added financial security over the long service life of the system. Hitouch 5B is the choice for those seeking a combination of modern technology, longevity, and elegant design in a single module.

What owners get
Back contact cells - no front-side grid

All electrical contacts are moved to the rear of the cell, leaving the front surface free of busbars and grid lines, delivering module efficiency of 23-24.5% and a uniform, aesthetic appearance ideal for facades and highly visible roofs.

Bifacial design with transparent rear glass

The module harvests additional energy from reflected light thanks to a transparent rear glass, increasing total annual yield compared to monofacial modules of similar 470-500 Wp nominal power.

Efficiency on par with segment leaders

Efficiency of 23-24.5% matches Gokin GK-3-54HGF (24.5%) and clearly exceeds Silfab SIL HM (21%) and Lina Energy LEPV 132 HC (21.06%) at the same 500 Wp max power - roughly 3.5 percentage points ahead of several comparable series.

30-year linear power warranty insured by Munich RE

The linear power warranty extends to 30 years and is backed by a Munich RE insurance policy, giving investors extra financial security over the long operating horizon, independent of the manufacturer's own standing.

Lower hot-spot and micro-crack risk

Electrical optimization and lower operating current reduce the risk of hot spots and micro-cracks, improving module durability under harsh conditions - salt mist, humidity, high temperatures, and ammonia exposure.

Trade-offs
No confirmed Tier-1 bankable status in provided data

Per the supplied context, Hanersun is not listed as Tier-1 bankable, which some lenders (banks, infrastructure funds) may treat as requiring additional collateral compared to established brands like Silfab. Worth verifying with the specific financier, since independent 2026 BNEF rankings indicate the manufacturer has since been recognized as Tier 1.

Product warranty range spans 15-30 years

Depending on the variant, product warranty ranges from 15 to 30 years - entry-level/earlier variants in the series offer only 15 years of product coverage, half the duration of the stated 30-year power warranty, so it's worth checking the specific model chosen.

About the Hitouch 5B series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is back contact (BC) cell technology in Hanersun Hitouch 5B panels and how is it different from standard cells?
In back contact technology, all electrical contacts and busbars are moved to the rear side of the cell, leaving the front surface completely smooth with no visible grid lines. This results in better light absorption and a uniform, aesthetic panel appearance. It's particularly suited to installations where both performance and looks matter, such as facades or roofs visible from the street.
Do the bifacial Hitouch 5B panels actually generate more energy?
Yes, thanks to the bifacial design with a transparent rear glass, the module captures additional energy from light reflected off the surrounding surface, such as a light-colored roof, gravel, or snow. The actual energy gain depends on the albedo of the surface beneath the panel and mounting height, but typically ranges from a few to over ten percent of annual output compared to a monofacial panel.
What warranty does the Hanersun Hitouch 5B come with, and is it backed by anything?
The Hitouch 5B series comes with a 30-year product warranty and a 30-year power warranty, well above the industry standard. As additional security, the warranty is insured by Munich RE, meaning the manufacturer's warranty obligations are backed by an independent insurer even if the manufacturer were to cease operations.
What is the power output of the Hitouch 5B panel and what installations is it suited for?
Hitouch 5B series modules reach a maximum power output of up to 500 Wp. High power combined with an aesthetic appearance makes them a good fit both for residential rooftop installations and prestigious commercial projects where visual appearance of the roof or facade matters alongside energy production.
Are Hanersun Hitouch 5B panels resistant to hot spots and micro-cracks?
Yes, thanks to electrical optimization and a lower operating current resulting from the back contact technology, the module has a reduced risk of hot spots and cell micro-cracks. This translates into higher durability in demanding conditions such as salt-laden air, high humidity, ammonia exposure, or elevated operating temperatures.
Is Hanersun a tier 1 manufacturer, and where are Hitouch 5B panels made?
Hanersun is a manufacturer based in China, but it is not currently listed as tier 1 under the Bloomberg NEF classification, which mainly evaluates bank financing scale rather than technology quality itself. In practice, panel selection should be based on technical specifications and warranty terms - and for the Hitouch 5B, the warranty being insured by Munich RE partly offsets the lack of tier 1 status.
