Scope 12 Inspection

Scope 12 Inspection: Why it Matters – And how ZigZagSolar Ensures Full Compliance

In the world of solar energy, safety is just as important as performance. This is especially true for large or integrated installations, such as solar façades on buildings. That’s why the Scope 12 inspection was introduced — a crucial safety standard that guarantees the quality, security, and insurability of solar installations in the Netherlands. 

At ZigZagSolar, we take Scope 12 compliance seriously. In this article, we explain what Scope 12 is, why it matters, and how we make sure every solar façade we deliver meets this critical standard. 

What is Scope 12? 

Scope 12 is a technical inspection standard established by SCIOS, the Dutch foundation for inspection and
certification of technical installations. It focuses on the electrical and fire safety of solar energy systems. 

The Scope 12 inspection covers: 

  • Proper electrical installation and connections
  • Mechanical safety and mounting quality 
  • Grounding, cabling, and inverter setup 
  • Fire hazard prevention and safety system functionality 

This inspection is especially relevant for larger systems, such as those on apartment complexes, commercial buildings, or properties managed by  housing associations (VvEs). In fact, many insurers require a valid Scope 12 inspection report before providing coverage. 

Why is Scope 12 so important 

  1. Fire safety: Poorly installed or aging solar systems can present a fire risk. Scope 12 helps detect and eliminate these issues right in the beginning.

  2. Insurance coverage: More and more insurers demand certified Scope 12 approval before insuring solar installations. 

  3. Trust and transparency: For property owners, developers, or public institutions, a certified installation ensures peace of mind and professional accountability. 

  4. Legal and social responsibility: Especially in public housing or commercial settings, verified safety is not just good practice — it’s essential. 

Turning How ZigZagSolar Ensures Scope 12 Compliance 

At ZigZagSolar, we specialize in architectural solar façades — custom solutions that combine smart energy generation with beautiful building design. While our façades may look sleek and futuristic, we never compromise on
safety. 

That’s why we partner exclusively with professionals who: 

  • Are certified to carry out Scope 12 inspections 

  • Provide complete documentation and testing reports for handover 

  • Offer periodic inspections and maintenance when needed 

From the early design phase to post-installation inspection, we guide our clients every step of the way. The result: a solar façade that not only looks good and performs well — but is also safe, insurable, and fully compliant. 

Conclusion

Scope 12 isn’t just a box to tick — it’s a vital part of any responsible solar project. Especially for large or integrated systems, it ensures lasting safety and performance. 

At ZigZagSolar, we go beyond aesthetics. We deliver solar façades that meet the highest technical and safety standards, giving our clients the confidence they need to invest in sustainable architecture.

Reimagining Old Buildings with Solar Innovation: ZigZagSolar for renovation and retrofits

Reimagining the Future of Existing Buildings

Architecture today isn’t just about bold new builds—it’s also about breathing new life into the spaces we already have. Across Europe and around the globe, architects, developers, and property owners are under increasing pressure to bring aging buildings up to modern sustainability and efficiency standards. 

That’s where ZigZagSolar steps in. 

As a leader in Building-Integrated Photovoltaics (BIPV), ZigZagSolar offers a transformative solution that combines elegant design with cutting-edge clean energy technology. By integrating solar power directly into building facades, railings, and other vertical surfaces, ZigZagSolar enables existing structures to generate their own renewable energy—without compromising on style or character. 

This isn’t just retrofitting—it’s rethinking what’s possible. 

ZigZagSolar helps future-proof your property by reducing reliance on the energy grid and enhancing resilience in a changing climate. Whether you’re updating a historic landmark or modernizing a commercial complex, ZigZagSolar empowers you to turn outdated exteriors into energy-producing assets—efficient, sustainable, and visually stunning. 

  

Why ZigZagSolar is the Perfect Retrofit Solution for Modern Buildings 

Redefining Solar with Seamless Design 

Retrofitting doesn’t have to mean compromising on aesthetics. ZigZagSolar’s Building-Integrated Photovoltaics (BIPV) are crafted to blend effortlessly with any architectural style—from historic landmarks to contemporary urban facades. With customizable finishes that replicate stone, wood, or even bespoke artwork, ZigZagSolar upgrades your exterior while preserving its character. 

 

More Than Just Solar: A Smarter Building Envolope 

Every retrofit faces space limitations. ZigZagSolar solves that by combining functionality in a single system. Our solar facades aren’t just energy producers—they double as exterior cladding, thermal insulation, and weatherproofing layers. It’s solar with a purpose. 

 

Turn Surfaces into Sustainable Power Sources 

ZigZagSolar transforms passive building exteriors into active energy generators, helping improve energy efficiency and reduce carbon footprints. This innovation supports green building standards like BREEAM and LEED, while opening the door to renewable energy incentives and government subsidies. 

 

Retrofit Projects That Speak for Themselves 

Verstegen Spices & Sauces, Rotterdam – One of our biggest custom solar facade projects! With 1,100+ solar cassettes, we transformed three building facades into energy-generating surfaces, producing 100,000 kWh annually. 

Windhondflat, Tegelen – South facade of Windhondflat residential complex in Tegelen was renovated with 132 solar cassettes, cutting tenant service costs while generating 19,000 kWh per year. A perfect blend of design & sustainability.  

 

The Economic Upside of Solar Facades 

Choosing ZigZagSolar means unlocking: 

  • Eligibility for solar subsidies and green tax incentives (e.g., SDE++, MIA/VAMIL, EIA)
  • Reduced energy bills and grid dependency
  • Enhanced property value through engery-efficient upgrades
  • Accelerated ROI for building owners and investors
 
Retrofit- Ready by Design

ZigZagSolar was made with retrofits in mind. Here’s how: 

  • Tailored BIPV designs that match or enhance existing architecture
