DNV, a leading independent energy expert and assurance provider, has launched an advanced network of solar resource measurement stations across Italy to accelerate solar development and support the country’s National Energy and Climate Plan (NECP) targets. These state-of-the-art stations measure solar irradiance, albedo (the reflectivity of surfaces), and soiling levels—providing high-accuracy data that enables developers to optimize system design, maximize energy yield, and enhance operational efficiency.

What sets this network apart is its focus on bifacial solar modules, which now represent nearly 40% of new installations in Italy. Each station includes dedicated albedo sensors designed specifically for bifacial technology, offering key insights into ground reflectivity. DNV research indicates that optimizing for albedo can increase energy output by up to 15%. Real-time soiling measurements also allow operators to reduce cleaning costs by up to 30% while maintaining performance, especially important for bifacial systems where surface conditions have a direct impact on output.

“Italy has enormous solar potential, but turning that potential into performance depends on accurate, site-specific data,” said Santiago Blanco, Vice President and Regional Director for Southern Europe, Energy Systems at DNV. “Our precise measurement stations provide exactly the kind of actionable insight developers need to deliver on Italy’s energy transition and Paris Agreement goals.”

Developed in collaboration with Cubico Sustainable Investments, the project underscores a shared commitment to accelerating the clean energy transition through data-driven innovation. It reflects DNV’s leadership in applying R&D-led solutions to meet both global technical standards and local market needs.

Key benefits for developers include:

High-precision irradiance and albedo data to optimize bifacial module performance

Real-time soiling ratio monitoring to inform cost-effective maintenance

Reliable solar resource assessments to guide project siting and investment decisions

As Italy aims to double its solar capacity by 2030, DNV’s high-fidelity data infrastructure will play a vital role in balancing energy production, grid reliability, and sustainability. This initiative cements DNV’s position as a trusted technical partner in shaping Italy’s renewable energy future.
