Across Europe, solar tenders are no longer decided on price alone. With the Net-Zero Industry Act (NZIA), supply-chain resilience has become a selection criterion, and that puts European manufacturing back at the centre of the game. Here’s what’s changing, and how SigueSol can help you turn it into an advantage.

What NZIA changes

Since the end of 2025, EU Member States must apply non-price criteria, resilience and sustainability, to a growing share of their renewable energy auctions (at least 30% of auctioned capacity, or 6 GW per year, weighted at 15% to 30% of the evaluation). The resilience criterion kicks in when a single non-EU country supplies more than 50% of EU demand for a given technology. Solar PV is squarely concerned: over 80% of its components are imported, mostly from China.

The takeaway for developers and EPCs: a diversified, European supply chain is becoming a competitive advantage in tenders, not just a procurement preference.

Italy moved first

Italy opened the way. Its first NZIA-criteria solar auction awarded 1.1 GW to projects built on non-Chinese components: modules, cells and inverters first and foremost. France and Belgium are expected to follow as the framework rolls out country by country. The direction of travel is clear: where your equipment comes from now matters.

Where SigueSol fits

As the Italian market increasingly promotes resilient and non-Chinese supply chains for strategic renewable energy projects, SigueSol offers a significant advantage:

• Our fixed-tilt structures and single-axis trackers contain no components sourced from China.
• Design, engineering and manufacturing are fully controlled within our European supply chain.
• Our solutions can support developers and EPCs seeking NZIA-compliant project configurations.

Beyond the product, our engineering teams stay alongside you to frame the configuration that best fits your terrain and your goals. You keep a direct technical contact, from design through to commissioning.

Two solutions built for NZIA-driven projects

HelioTrack 1P – Single-Axis Tracker

HelioTrack 1P is a robust horizontal single-axis tracker developed for utility-scale and agrivoltaic applications. Its multi-actuator architecture, validated through wind tunnel testing, ensures high structural stability and operational reliability. The advanced control system combines astronomical tracking and adaptive backtracking algorithms to maximize energy production. The tracker can accommodate from 18 to 120 modules per row, withstand wind speeds up to 180 km/h in storm position, and adapt to challenging terrain conditions.

HelioGround Flex – Fixed-Tilt Structure

HelioGround Flex is an all-terrain, dual-post ground-mounted structure designed for maximum adaptability and durability. Its innovative tube-in-tube sliding design allows continuous adjustment of height and tilt, even compensating for differential settlement during operation. The system can combine screw piles and concrete foundations within the same table and is optimized for bifacial modules thanks to its minimal rear shading. It is designed according to Eurocodes and offers a service life exceeding 35 years.

As NZIA-driven tenders and procurement processes become more common across Italy and Europe, this positioning could represent an important differentiator for SigueSol and our customers.
