The AU-156MH series of photovoltaic panels are modules designed for high energy yields in installations where both power and stable performance in varying conditions are crucial. The use of monocrystalline cells in a half-cut configuration minimizes losses at connections and improves performance under partial shading - making the installation less sensitive to chimneys, skylights, or snow drifts. The module's design is suitable for large roof and ground-mounted projects, where repeatability of parameters and easy installation in standard mounting systems are important.

In practice, the AU-156MH helps reduce energy costs by maintaining efficiency for longer and providing predictable performance in hot weather - which contributes to favorable temperature characteristics. An additional advantage is the watertight connection box with a high level of protection, which improves the safety of operation in harsh environments. This is a good choice for investors who want to maximize production without "over-sizing" the roof or land.

Common questions

6 answered
What cell technology does the Ulica Solar AU-156MH use, and how does it differ from PERC?
The AU-156MH series uses monocrystalline TOPCon (Tunnel Oxide Passivated Contact) cells, which offer higher conversion efficiency and lower power loss at high temperatures compared to older PERC technology. This helps the module maintain more stable energy output on hot days, resulting in higher annual energy yield, particularly in installations operating in warmer climates.
Does the half-cut cell design in the AU-156MH actually improve performance under partial shading?
Yes. Splitting cells in half reduces resistive losses at interconnections and means that shading part of the panel, for example from a chimney or dormer, no longer disables the whole module but only the affected section. In practice this results in smaller output drops in installations with shading obstacles, which is important for complex roof layouts.
Is the Ulica Solar AU-156MH bifacial, generating power from the rear side as well?
No, the AU-156MH series consists of mono-facial modules - power is generated only from the front side of the panel. If additional yield from reflected light is important to you, consider a bifacial model from another Ulica Solar series instead. The AU-156MH is a solid choice for standard rooftop installations where double-sided generation isn't applicable.
What warranty applies to the Ulica Solar AU-156MH solar panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty guaranteeing a minimum efficiency level throughout the panel's service life. This is comparable to offerings from many leading manufacturers, though it's worth comparing terms against Tier 1 brands.
Is the AU-156MH suitable for large rooftop and ground-mount PV installations?
Yes, the module was designed with commercial and industrial projects in mind - both large industrial rooftops and ground-mount installations. Consistent electrical parameters and standard dimensions make it easier to integrate with typical mounting systems, which lowers installation costs on larger-scale projects.
Is the Ulica Solar AU-156MH series still available for purchase?
No, production of the AU-156MH series has ended and the model has been discontinued from the manufacturer's current lineup. Availability is now limited to remaining distributor stock. Buyers looking for a replacement should check Ulica Solar's current TOPCon series with comparable power output, which have superseded this model in the product portfolio.
