Built to withstand the extreme

When investing in solar, reliability is not a luxury, it is essential.

BISOL photovoltaic modules are designed to perform year after year, in the most demanding conditions on Earth.

From the frozen landscapes of Antarctica to the heat of remote island resorts and the snow-laden rooftops of Europe, BISOL delivers what others only claim. Consistent, real-world durability proven over time.

Proven where others fail.

Some modules pass laboratory tests, few survive real life.

BISOL modules operate reliably in more than 120 countries, across all major climate zones. From hailstorms to heatwaves, from high altitudes to coastal salt spray, BISOL stands strong where others fall short.

• Hail resistance: Certified to HW4. BISOL modules withstand

  40 mm hail at 99.1 km/h, thanks to 3.2 mm tempered glass.

• Snow load: Engineered for stability, up to 6,000 Pa (BDO),

  7,000 Pa (BBO), and 11,000 Pa (BSO).

• Wind load: Tested to 2,400 Pa - the global benchmark for roof-mounted solar.

• Temperature resilience: BISOL modules endure thermal cycling and damp heat far beyond industry norms.

From Japan to Canada, from high mountains to the sea, BISOL performs with confidence.

Not just certified. Verified in every module.

Certification is important. But it is just a starting point.

At BISOL, every single module is built to the same high standard, not just the sample tested for approval.

What makes the difference:

• 100% EU production in Slovenia.

• Full material and process traceability via QR code.

• Open-door policy for factory visits and audits.

• Long-term partnerships based on trust.

BISOL modules are not just made to perform. Instead, they are built to last.

With superior materials, precise European manufacturing, and over 20 years of real-world performance data, BISOL offers one thing no one else can:

Proven durability, designed into every detail.
