The SV120M.2 series consists of monocrystalline Full Black photovoltaic modules designed for installations where both aesthetics and long-term reliability matter. The panels use PERC cells arranged with half-cut technology, significantly reducing power losses from shading and the hot spot effect, so the module maintains stable energy output even under less favorable irradiance conditions. The use of five busbars improves current collection from the cells and increases the mechanical strength of the connections, which translates into a lower risk of microcracks and failures over the module's service life. The module surface is coated with a self-cleaning SELF-C coating, reducing dirt buildup and helping maintain high efficiency without frequent maintenance. The panels are resistant to potential-induced degradation (PID-free), and the manufacturer guarantees only positive power tolerance, eliminating the risk of receiving a unit below the declared parameters. The SV120M.2 series works well in both residential and commercial installations, where investors expect a sleek full black look combined with high mechanical durability and genuine service support in Poland, backed by a domestic manufacturer.

About the SV120M.2 series

6 answered

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

Are Selfa SV120M.2 solar panels still available for purchase?
The SV120M.2 series has been discontinued and replaced by newer models in Selfa's lineup. Availability is now limited to remaining distributor stock. The manufacturer's warranty (12 years product, 25 years linear power) remains valid for units already purchased and installed, regardless of the series being discontinued.
What warranty comes with Selfa SV120M.2 panels?
The manufacturer provides a 12-year product warranty and a 25-year linear power warranty. Selfa is a Polish manufacturer headquartered domestically, so warranty service and claims are handled locally, without the need to contact an overseas manufacturer or wait long for replacement parts.
What benefit does half-cut technology bring to the SV120M.2 panels?
The half-cut PERC cells reduce power losses from partial shading, such as from chimneys, antennas, or leaves. Shorter current paths also limit the hot spot effect and resistive losses, resulting in higher module efficiency and lower risk of individual cells overheating during operation.
Are SV120M.2 panels resistant to PID degradation?
Yes, the SV120M.2 modules are designed as PID-free, meaning they resist potential-induced degradation. This means that under typical system voltages, the panels do not experience the gradual efficiency loss caused by potential differences between the cell and the frame, ensuring stable energy output throughout their service life.
How much power does a single Selfa SV120M.2 panel generate?
The SV120M.2 module reaches a maximum power output of 320 Wp. This is a typical value for smaller monocrystalline panels in this class, suited for limited roof space or when an investor prioritizes an aesthetic full-black appearance while still achieving solid, though not record-breaking, energy output.
How is the SELF-C coating different from a standard PV panel glass surface?
The SELF-C self-cleaning coating reduces the adhesion of dust, pollen, and grime to the glass surface, allowing rain to wash away buildup more effectively. In practice, this means less frequent manual cleaning and lower risk of efficiency loss from a dirty surface, especially in installations that are hard to service.
