Quality is not a preference. It is risk management.   After record installation volumes in 2025, the photovoltaic market is entering a different phase. Margins are tighter. Financing criteria are stricter. Warranty claims and system failures carry real financial consequences.  In 2026, the key question is no longer who offers the lowest price per watt .  The real question is who carries the lowest risk over the next 20 to 30 years .    This is where quality stops being a mark

Latkova vas, Slovenia – December 23, 2025  – BISOL Group, Europe’s largest premium manufacturer of photovoltaic modules, expresses concern over the current wording of Article 94 in Italy’s draft budget law, which proposes to exclude the majority of European PV manufacturers from the country’s new tax incentive scheme by restricting eligibility to only certain categories in the ENEA registry. This would effectively exclude nearly all European PV manufacturers listed under sect

Please note that BISOL Group will observe a collective holiday from December 25, 2025, to January 4, 2026 . During this period, our offices will be closed. Normal operations will resume on January 5, 2026 .  Thank you for your understanding. We look forward to reconnecting in the new year.

It becomes a reflection of the identity, values and character of its owner.   A New Feature in Solar: Personalised Engraving on BISOL Supreme™ Customers can now choose to have their name, family

When winter covers rooftops and solar farms in a thick layer of snow, not all PV modules can handle the pressure. Snow accumulation can exert several thousand Pascals of force on photovoltaic panels. Without proper engineering, that pressure can bend frames, crack glass, or damage solar cells. That’s where BISOL, Europe’s largest PV manufacturer, sets itself apart. Engineered for Heavy Snow Loads   BISOL modules are tested to remain mechanically stable under substantial loads

High-performance solar modules are not defined by watt-peak alone. They are defined by the depth of engineering, the integrity of the manufacturing process, and the intelligence of the system that supports them throughout their lifetime. For more than 20 years, BISOL has been committed to exactly that. Our solar modules are fully developed and manufactured in the European Union, with complete control over materials, quality processes, and long-term performance. But our exp

That is why BISOL solar modules are engineered for decades of reliable performance, delivering lasting value with minimal environmental and financial impact. Why Durability Matters Every year of seamless operation saves more than just electricity. It avoids maintenance, costs, and carbon footprints associated with r

A moment of shared knowledge, valuable insights, and solar expertise.  During the recent Energia Italia webinar , Marco De Bortoli, Sales Engineer at BISOL Group , offered participants an in-depth look at BISOL’s 20+ years of experience in the solar industry, from precision manufacturing and quality assurance to our diverse range of high-efficiency solar modules.  He highlighted the latest Italian and EU regulations promoting the use of EU-made modules and explained why choos

As autumn arrives and days grow shorter, many assume PV module efficiency naturally drops. But in reality, this season often brings some of the best conditions for photovoltaic performance, especially for Europe's largest PV module manufacturer BISOL® .  Why Summer Heat Isn’t Always Ideal for PV module efficiency   While summer offers long days, it also brings high temperatures that can reduce module efficiency. Photovoltaic cells perform best in cooler conditions: as ambient
