The Sunova Tangra S Pro C Black series redefines the standards of aesthetics and performance in modern photovoltaic systems. Utilizing advanced N-type TOPCon cell technology, these modules eliminate the problem of rapid power degradation, ensuring stable energy yields for investors for many years. Their key advantage over standard solutions is exceptional efficiency in low-light conditions, which allows the installation to produce electricity effectively even on cloudy days or at low sunlight angles. Deep, uniform Full Black aesthetics make the panels an integral part of the architecture, blending perfectly with dark roof coverings without visible silver frames or cells. The solid frame construction and high resistance to mechanical loads ensure this series handles extreme weather phenomena, such as violent wind or heavy snow, perfectly. This is a solution created for demanding home users for whom the priority is maximizing production from a small roof area while maintaining the highest operational standards for the modules. What sets them apart from the competition is an optimized temperature balance that prevents cells from overheating and performance drops on hot days, guaranteeing a faster return on investment in the Polish climate.

Common questions

6 answered
What is the maximum power output of the Sunova Tangra S Pro C Black panel?
The Tangra S Pro C Black series reaches up to 450 Wp, with N-type TOPCon cell efficiency of around 22.5%. That is a strong result for a compact 1762x1134 mm module, allowing more energy yield per square meter of roof compared to older P-type panels of similar size.
What does bifacial technology offer in the Tangra S Pro C Black panels?
Thanks to the dual-glass bifacial construction, the panel also captures light reflected off the surrounding surface through its rear side. On a bright roof, white gravel, or ground-mount installation, this can boost energy production by up to several percent compared to a standard monofacial module, with the exact gain depending on surface color and mounting height.
What warranty comes with Sunova Tangra S Pro C Black panels?
The manufacturer offers a 15-year product warranty covering material and workmanship defects, plus a 30-year power output warranty, which is standard for modern N-type TOPCon modules. This means that even after 30 years the panel should still generate a significant share of its original power, supporting a longer and more predictable return on investment.
Are the Sunova Full Black panels suitable for a dark sloped roof?
Yes, the Tangra S Pro C Black series is designed with aesthetics in mind — a uniform black frame, black backsheet, and no visible silver components make it blend well with dark roof tiles or metal roofing. The frame is certified for wind loads up to 2400 Pa and snow loads up to 5400 Pa, confirming its suitability for typical sloped-roof conditions in Poland.
Do Sunova Tangra S Pro C Black panels perform well in low temperatures and low irradiance?
Yes, these modules feature a low power temperature coefficient, which limits performance losses on hot days while also supporting stable output in winter. Additionally, N-type TOPCon cell technology improves behavior under low irradiance, so the system still generates electricity on cloudy days or at the low sun angles typical of Polish autumn and winter.
Who manufactures Sunova panels, and are they a Tier 1 manufacturer?
The Tangra S Pro C Black panels are made by Sunova Solar Technology, a Chinese company specializing in N-type modules. Sunova is not currently listed as a Tier 1 manufacturer under BloombergNEF's classification, though this doesn't directly affect the module's technical quality — it's worth checking this criterion only if project financing specifically requires Tier 1 panels.
