The Yingli YLM 3.0 Plus 1 series is designed for high energy production on limited mounting surfaces, making it ideal where every square meter of roof or field space counts. These modules utilize p-type monocrystalline PERC solar cells, and their refined interconnection architecture ensures stable performance even under partial shading and uneven irradiance, common in many Polish installations. A key feature is the glass-glass construction, which enhances environmental resistance and facilitates maintaining parameters over a long period - a real advantage in projects exposed to wind, humidity, and temperature fluctuations. The series targets high reliability in challenging conditions thanks to high-quality lamination materials and robust construction. The YLM 3.0 Plus 1 is a solid choice for commercial and utility-scale PV projects, where dependable power generation and long-term durability take precedence over catalog specifications.

About the YLM 3.0 Plus 1 series

6 answered

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

What is the maximum power output of the Yingli YLM 3.0 Plus 1 panel?
The top variant of the YLM 3.0 Plus 1 series reaches up to 670 Wp, thanks to 132 large p-type monocrystalline PERC cells. This allows high energy yield from fewer modules, which meaningfully reduces installation time and mounting structure costs in commercial installations and utility-scale PV farms.
How does the glass-glass construction of the YLM 3.0 Plus 1 differ from standard glass-backsheet panels?
Unlike typical panels with a rear backsheet layer, the YLM 3.0 Plus 1 encapsulates its cells between two glass panes. This design better protects the cells from moisture, microcracks, and PID degradation, resulting in a slower power decline over time and greater resistance to harsh weather conditions such as strong wind or hail.
What warranty comes with the Yingli YLM 3.0 Plus 1 panels?
The manufacturer offers a 12-year product warranty along with a 30-year linear power output warranty. This means that after 30 years of operation, the panel should still retain the guaranteed minimum percentage of its initial output, a standard expectation for modern glass-glass modules from a tier 1 manufacturer.
Is the YLM 3.0 Plus 1 suited for large-scale PV farms or more for residential roofs?
This series is designed primarily for commercial installations and utility-scale PV farms, where predictable energy yield and long-term durability matter more than raw datasheet figures. Its large format and high unit power (up to 670 Wp) make it better suited to large mounting areas than to a typical single-family sloped roof.
Are the YLM 3.0 Plus 1 panels bifacial, generating power from the rear side?
No, the YLM 3.0 Plus 1 series uses standard monofacial PERC cell architecture. The glass-glass construction here is meant to boost durability and environmental resistance, not add rear-side power generation - this sets it apart from bifacial models in Yingli's lineup.
Who manufactures the YLM 3.0 Plus 1 panels, and is it a reliable tier 1 supplier?
The YLM 3.0 Plus 1 panels are made by Yingli, a Chinese manufacturer with decades of industry experience, classified as a tier 1 supplier. This reflects solid financial standing and proven manufacturing capacity, which matters when pursuing warranty claims over the multi-decade lifespan of a PV installation.
