The SV108M.3.4 series consists of photovoltaic modules built on the latest TOPCon N-Type technology, designed for investors who expect stable energy output even under demanding weather conditions. Half-cut cells arranged in a multi-busbar layout reduce resistive losses and improve tolerance to partial shading, allowing the panel to maintain performance even when a roof receives uneven sunlight. What sets this series apart is the patented SELF-C self-cleaning coating, which limits the accumulation of dust, pollen, and other contaminants on the glass surface, resulting in less frequent maintenance and more consistent yields over time. The module's construction has been reinforced for increased mechanical durability, withstanding snow and wind loads up to 8000Pa as well as hailstones up to 55mm in diameter, making it a solid choice for roofs exposed to harsh weather, including installations in northern and central Poland. A black frame version is also available for projects where facade aesthetics matter. The SV108M.3.4 series is well suited both for installers handling residential projects and for companies seeking a reliable component for larger commercial installations, where long-term durability and a predictable LCOE are essential.

About the SV108M.3.4 series

6 answered

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

What is TOPCon N-Type technology used in Selfa SV108M.3.4 panels, and how does it differ from standard PERC panels?
TOPCon N-Type is a newer generation of silicon cells that, compared to the popular PERC technology, offers higher conversion efficiency (around 21.5% for the SV108M.3.4), lower power degradation over time, and better performance at high temperatures. Combined with multi-busbar technology and half-cut cells, it reduces resistive losses and improves yield stability, resulting in higher energy production over the system's lifetime.
Do Selfa SV108M.3.4 panels with the SELF-C coating need regular cleaning?
Not under typical conditions. The patented SELF-C self-cleaning coating reduces the buildup of dust, pollen, and other contaminants on the glass, so most of it is washed away by rainfall and UV radiation alone. In practice, this means less frequent system servicing and more stable year-round energy yields, especially on roofs that are hard to access.
Can Selfa SV108M.3.4 panels withstand heavy wind, snow loads, and hail, e.g. in northern Poland?
Yes, the module's construction has been reinforced for increased mechanical resistance, withstanding snow and wind loads up to 8000Pa as well as hail impacts up to 55mm in diameter. This makes the SV108M.3.4 a solid choice for roofs exposed to harsh weather conditions, including installations in northern and central Poland where snow loads can be significant.
What warranty comes with Selfa SV108M.3.4 solar panels?
The manufacturer provides a 20-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the panel maintains a defined minimum energy output level for three decades as specified in the datasheet, giving investors predictable yields and a favorable impact on long-term LCOE calculations.
Is the Selfa SV108M.3.4 a bifacial panel that generates power from both sides?
No, the SV108M.3.4 series is a monofacial module, optimized for standard mounting on pitched and flat roofs where the rear side has no access to reflected light. If you're planning a ground-mounted installation or one on a bright, reflective surface, a bifacial model from the manufacturer's lineup may be worth considering, but for typical rooftop installations the SV108M.3.4 is a fully adequate solution.
Who is the Selfa SV108M.3.4 series designed for, and is a black frame version available?
The SV108M.3.4 suits both installers handling residential projects and companies looking for a reliable component for larger commercial installations, where durability and predictable energy cost matter most. A black frame version is also available, well suited to projects where facade aesthetics are a priority, such as roofs visible from street level.
