The Yingli YLM 3.0 Mini 1 series is designed for installations where high power density is key, while maintaining a convenient and compact module format. This is an ideal solution for individuals and companies seeking to extract maximum performance from rooftops with limited surface area or more challenging roof geometries - without compromising on manufacturing quality. The series stands out due to its half-cell architecture, which helps reduce resistive losses and stabilizes module performance under partial shading. The applied multi-busbar technology improves current collection and increases resistance to microcracks, which is particularly important in Polish conditions (snow, wind, freeze-thaw cycles). The series also emphasizes high reliability in harsh environments, thanks to refined lamination and layer structure design. The YLM 3.0 Mini 1 will perform excellently in single-family homes, small and medium-sized businesses, and renovation projects where long-term, reliable performance and predictable energy yield are crucial.

About the YLM 3.0 Mini 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 Mini 1 panel?
Panels from the YLM 3.0 Mini 1 series reach a maximum power output of up to 415 Wp. Given the module's compact mini format, this represents a very good power density, allowing more energy to be generated from a limited roof area compared to older, less efficient module designs.
Is the Yingli YLM 3.0 Mini 1 suitable for roofs with limited space or unusual geometry?
Yes, this is one of the series' main use cases. The compact module format makes it easier to fit smaller roof sections, dormers, or complex roof shapes. The half-cut cell architecture also improves performance under partial shading, which is common on such roofs.
What warranty comes with the Yingli YLM 3.0 Mini 1 panels?
The manufacturer offers a 12-year product warranty and a 30-year power performance warranty. Yingli is a tier 1 manufacturer, which further increases confidence that the warranty will actually be honored over such a long time horizon, not just exist on paper.
How does the PERC technology in the YLM 3.0 Mini 1 differ from standard cells?
PERC cells feature an additional passivation layer on the rear side that reflects unused light back into the cell, increasing conversion efficiency. Combined with multi-busbar technology, this improves current collection and reduces losses, resulting in higher energy yield from the same panel surface area.
Does the YLM 3.0 Mini 1 perform well in Polish climate conditions?
Yes, the series is designed for demanding operating conditions such as snow, strong wind, and freeze-thaw cycles. Multi-busbar technology increases resistance to microcracks, while careful lamination and layer construction reduce the risk of module degradation in variable climates.
Is the YLM 3.0 Mini 1 a bifacial panel?
No, the YLM 3.0 Mini 1 series uses monofacial PERC cells, generating power only from the front side of the module. This makes it well suited for standard rooftop installations, where the module is mounted directly on the roof surface with no light access from the rear.
