The SoliTek SOLID White Framed series is a range of photovoltaic panels designed for installations where aesthetics are just as important as performance. They are characterized by a white anodized aluminum frame combined with a white rear glass, making the modules perfectly complement light facades, white-covered roofs, or modern pergolas and carports. Technologically, the series is based on N-type TOPCon bifacial cells - a next-generation solution that provides an exceptionally low annual degradation rate of 0.40%, guaranteeing up to 87.4% power after 30 years of operation. The 2+2 mm glass construction with an anti-reflective coating on the front, as well as its ability to withstand extreme snow loads, makes the series suitable for the challenging climate conditions of Poland. The modules have certifications for resistance to salt and ammonia corrosion, making them suitable for industrial and agricultural environments as well. A key advantage in the Polish market is compliance with the FER X program, which simplifies the process of obtaining funding. The series is aimed at individual investors and developers seeking modules that combine high durability with a modern appearance.

Common questions

6 answered
Is the SoliTek SOLID White Framed series still available for purchase?
The SoliTek SOLID White Framed series has been discontinued and is no longer offered as a new product. If you need a similar aesthetic — white frame combined with N-type TOPCon bifacial technology — ask your distributor about a current alternative from SoliTek's lineup or another European manufacturer. Stock availability at individual resellers may vary.
What warranty does SoliTek provide on the SOLID White Framed panels?
SoliTek offers a 25-year product warranty and a 30-year power output warranty on the SOLID White Framed series. The manufacturer guarantees at least 87.4% of nominal power after 30 full years of operation, which is backed by an exceptionally low annual degradation rate of 0.40% — well below the 0.55% market standard for PERC-based modules.
What does bifacial technology mean in the SoliTek SOLID White Framed series, and is it worth the premium?
Bifacial means the N-type TOPCon cells generate electricity from both sides of the module — direct irradiance on the front and reflected albedo light on the rear. The white back glass in the SOLID White Framed series enhances this effect by bouncing additional photons back into the cells. In practice, when installed above a light-colored surface or white facade, annual energy yield can increase by 5–15% without adding extra roof area.
Are SoliTek SOLID White Framed panels suitable for a white roof or pergola?
Yes, that is one of the primary use cases for this series. The white anodized aluminum frame and white rear glass allow the modules to blend seamlessly with light-colored rooftops, modern carports, and pergolas. The 2+2 mm glass-glass construction with an anti-reflective front coating provides adequate snow load resistance for Central European climates. The modules also carry salt and ammonia corrosion resistance certifications.
What is the maximum power output of the SoliTek SOLID White Framed module, and is it a good fit for a large installation?
The top variant in the series reaches 720 Wp. This power level is typical of large commercial-grade modules, making the series well-suited for both sizable residential prosumer systems and developer-scale projects. Higher per-module wattage reduces the total number of panels required, lowering balance-of-system (BoS) costs — racking, wiring, and labor — for any given target system size.
Does an installation using SoliTek SOLID White Framed panels qualify for the Polish FER X subsidy program?
Yes, the SOLID White Framed series meets the requirements of Poland's FER X subsidy program, which simplifies the grant application process for both individual investors and developers. However, since the series has been discontinued, we recommend confirming the validity of the certification with your distributor before submitting an application, as program requirements may have been updated.
