The SOLID Satin Framed series features a unique anti-glare glass technology, SATIN, which diffuses light directly through the glass structure - without additional coatings or films. This results in a luminance level that is more than three times lower than the market standard, eliminating distracting reflections while maintaining high energy efficiency. This is a key advantage in locations sensitive to glare, such as road shoulders, airports, railway stations, or densely populated urban areas. The panels utilize a bifacial glass-to-glass technology, allowing for energy generation from both the front and back sides of the module. The black aluminum frame gives them an aesthetically pleasing and discreet appearance, making them ideal for visually prominent installations, such as roofs of public buildings, covered parking areas, and building-integrated photovoltaic (BIPV) systems. Resistance to extreme weather conditions - hail up to 5 cm, strong winds, and snow loads - along with DIBt certification, confirm the suitability of this series for critical infrastructure. A 30-year product warranty and a designed lifespan of 50 years make this a long-term, cost-effective investment. SOLID Satin Framed modules are manufactured in Europe, guaranteeing high quality control standards and short supply chains.

Common questions

6 answered
How does the SATIN glass in Solitek SOLID Satin Framed panels differ from standard anti-reflective glass?
SATIN glass scatters light through the glass structure itself, with no additional coatings or films. This reduces luminance to below 3,600 cd/m², compared to the market standard of over 10,000 cd/m² — more than a threefold reduction in glare. Power loss versus standard glass is only approximately 2.3%, so anti-glare performance comes at virtually no efficiency cost.
How much extra energy do I get from the bifacial glass-glass design of the SOLID Satin Framed series?
The TOPCon bifacial design harvests energy from both the front and rear of the module. Real-world bifacial gain depends on ground albedo and tilt angle, but typically ranges from 5% to 20% above a monofacial module with the same 445 Wp nameplate rating. The glass-glass construction (two 3.2 mm panes) also extends the projected service life to 50 years.
What types of installations is the Solitek SOLID Satin Framed series best suited for?
The series was designed for glare-sensitive locations such as roadsides, airports, railway stations, and densely built urban areas. The all-black aluminum frame and clean aesthetics also make it an excellent fit for BIPV systems, public-building rooftops, and carport canopies where visual integration matters as much as energy output.
What warranty does the Solitek SOLID Satin Framed series carry, and what is the expected service life?
Solitek provides a 30-year product warranty covering manufacturing defects and a 30-year power output warranty guaranteeing performance retention over that period. The modules are engineered for a projected 50-year operational lifespan, making them a strong long-term investment for critical infrastructure projects with extended payback horizons.
What does DIBt certification mean and why does it matter when choosing SOLID Satin Framed panels?
The DIBt (Deutsches Institut für Bautechnik) certificate is one of Europe's most stringent structural approvals for PV modules. It confirms the panels withstand snow loads up to 10,500 Pa, wind loads up to 4,500 Pa, and hail up to 5 cm in diameter. DIBt certification is frequently required for critical infrastructure tenders and commercial projects across the EU.
Where are Solitek SOLID Satin Framed panels manufactured, and does that affect quality?
The modules are manufactured by Solitek in Lithuania, making them a European Union product subject to strict quality controls. EU-based production shortens lead times, reduces supply-chain risk, and enables direct process oversight — all of which contribute to consistent electrical parameters and reliable warranty enforcement.
