The Forza series is SoliTek's response to the growing demands of the market for large-scale and commercial installations. By utilizing N-type TOPCon cells in a bifacial configuration, the panels generate energy from both the front and back sides, resulting in significantly higher yields in ground-mounted and reflective installations. The construction, based on a 2+2 mm double-sided glass with an anti-reflective coating, eliminates the risk of PID (Potential Induced Degradation) and provides exceptional mechanical strength - the panels easily withstand extreme snow loads, making them an ideal choice for Polish climatic conditions. The white aluminum frame aesthetically enhances the Forza, which investors appreciate for its consistent appearance on roofs or ground. The panels are certified for resistance to saline fog and ammonia, opening up possibilities for use in coastal and agricultural areas. A 25-year product warranty and a 30-year power warranty with an exceptionally low annual degradation rate are key advantages for installers and investors seeking modules with a long, reliable lifespan. Furthermore, the Forza is approved for the FER X program, which facilitates the qualification of installations for European funding and support programs for renewable energy.

Common questions

6 answered
What warranty does the SoliTek Forza series come with?
The Forza series includes a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty with an exceptionally low annual degradation rate inherent to N-type TOPCon cells. This means the manufacturer guarantees a specified minimum power output for three decades of operation — a key factor when calculating the LCOE of a commercial PV or utility-scale project.
Is the SoliTek Forza suitable for a solar farm or large ground-mount installation?
Yes. The Forza series is specifically engineered for large-scale and commercial installations. The bifacial N-type TOPCon cell layout harvests energy from both the front and rear surfaces, delivering measurably higher yields on ground-mount systems with reflective ground cover (albedo). At up to 720 Wp per module in the B132 format, Forza reduces total panel count and lowers BoS costs per installed megawatt.
What is TOPCon technology in the SoliTek Forza, and is it worth the premium over older PERC modules?
TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology achieving efficiencies above 23%. Unlike PERC cells, N-type silicon is not susceptible to light-induced degradation (LID), which translates into higher real-world energy output over the module's entire lifetime. Combining TOPCon with a bifacial design in the Forza series maximizes energy harvest per square meter and improves the overall return on investment.
Can SoliTek Forza panels handle heavy snow loads typical of Central European winters?
Yes. The dual-glass 2+2 mm tempered construction with anti-reflective coating provides exceptional mechanical strength against extreme snow and wind loads common in the Polish climate. The glass-glass design also eliminates the risk of PID (Potential Induced Degradation), which shortens the service life of conventional backsheet modules — making Forza a reliable choice for year-round outdoor operation.
Can SoliTek Forza panels be safely deployed near the coast or on agricultural sites?
Yes. The Forza series carries salt mist and ammonia resistance certifications, making it safe for coastal zones and agricultural environments where ammonia emissions from fertilizers and livestock operations can degrade standard modules over time. This makes the series an excellent fit for agrivoltaic projects and ground-mount farms in coastal or intensive-farming regions.
Is the SoliTek Forza series eligible for European renewable energy incentive programs such as FER X?
Yes. Forza panels are approved for the FER X program, simplifying qualification for European renewable energy support mechanisms. Manufacturing in Europe (Lithuania) also aligns with the EU's NZIA requirements that favor modules produced to European industrial standards — an important advantage for public tenders and projects seeking EU co-funding.
