The SV120M.2.4 series consists of bifacial Selfa photovoltaic modules built on N-Type cells and half-cut technology, which reduces energy losses and keeps performance stable even under partial shading. The panels feature a bifacial full black construction with tempered glass on both sides, capturing light reflected from the ground and delivering a real yield increase compared to standard monofacial modules. The multi-busbar layout improves connection reliability and lowers the risk of microcracks, while PID resistance ensures stable operation of the installation over many years. An additional advantage is the self-cleaning SELF-C coating, which helps maintain high panel efficiency even with limited access for maintenance, for example on hard-to-reach rooftops. The uniform black frame gives the series a clean look, making it a good fit for installations where roof or facade aesthetics matter. The SV120M.2.4 is aimed at investors looking for a more efficient alternative to standard monofacial panels, suitable for both residential and commercial installations where a lower cost per watt and a long-term manufacturer warranty backed by over eighty years on the market are key considerations.

Common questions

6 answered
Are Selfa SV120M.2.4 solar panels still available for purchase?
The SV120M.2.4 series has been discontinued and is no longer part of Selfa's current product catalog. Panels may still be available through distributors as remaining stock, but once inventory runs out, no further units will be manufactured. Anyone planning to extend an existing array with matching modules should act quickly or consider a newer equivalent from the current lineup, such as the SV120M.3.4 series.
How much extra energy can bifacial SV120M.2.4 panels generate compared to standard modules?
Thanks to the bifacial full black construction with tempered glass on both sides, SV120M.2.4 panels also capture light reflected off the ground surface. Under favorable albedo conditions, such as a light-colored surface or a white roof membrane, energy yield can increase by up to 25% compared to a classic monofacial module of the same 500 Wp rated power.
What warranty comes with Selfa SV120M.2.4 solar panels?
The manufacturer offers a 20-year product warranty along with a 30-year power output warranty. This means the module is expected to maintain a guaranteed efficiency level over three decades according to its power degradation curve, while for the first 20 years the manufacturer covers material and workmanship defects in the module itself.
How do the N-type cells in SV120M.2.4 differ from standard PERC cells?
N-type cells, unlike widely used PERC (P-type) cells, offer higher efficiency (up to 22.60% in this model), a lower annual degradation rate, and reduced sensitivity to LID and PID. Combined with half-cut technology and multiple busbars, this results in more stable module performance and lower energy losses throughout the system's operating life.
Are SV120M.2.4 panels suitable for roofs that are hard to clean?
Yes, the modules feature the SELF-C self-cleaning coating, which reduces dust and dirt buildup on the glass surface and allows rain to rinse it off more effectively. This is especially useful on low-pitch roofs or in locations where regular maintenance is difficult, as it helps maintain high panel efficiency without frequent service intervention.
Who manufactures Selfa panels, and is it a Tier 1 manufacturer?
Selfa is a Polish manufacturer with over eighty years of history in the market, though it is not formally listed as a Tier 1 manufacturer under the BloombergNEF classification, which primarily rates the scale of bank financing behind module production rather than module quality itself. For many buyers, the domestic origin of the product and local warranty support are significant advantages when choosing panels for a residential or commercial installation.
