When Liselotte talks about her career, she describes a journey shaped by curiosity and the desire to work closer to the heart of a business. She began her professional life at a large law firm, which she calls “an intense but incredibly valuable learning experience.” Over time, however, she felt something was missing. She wanted cross-disciplinary collaboration, a flatter and more accessible organisation, and a role connected more directly to commercial and operational decision-making.

That shift began prior to Sunrock, during the last year and a half of her traineeship, when she joined a smaller M&A energy team. This is where the energy transition first captured her attention. “It combined the energy of transactions with a clear sense of purpose and impact,” she explains.

An interim assignment eventually brought her into contact with Sunrock. From the very beginning, she felt at home. The organisation’s cross-functional way of working and its mission to scale clean energy solutions matched exactly what she had been looking for.

A Role Shaped by Variety

Today, Liselotte works in a hybrid role that brings together hands-on legal work, strategy, process design, and mentoring. Her scope spans everything from leases and rights of superficies to EPC and O&M agreements, general terms and conditions, and notices of default. She also develops templates, contracting playbooks, and guidelines that support Sunrock’s growth.

What she values most is the diversity of her work. “No two days are the same, and that’s exactly what I enjoy about the role,” she says. One moment she might be deep in a legal analysis or negotiating with a customer’s counsel, and the next she is designing a new process or coaching a colleague.

What Makes Sunrock Stand Out

For Liselotte, Sunrock’s strength lies in its combination of a young, ambitious team and a culture defined by accessibility and openness. She loves that colleagues challenge one another, share knowledge freely, and work closely across countries, departments, and seniority levels. This environment allows people to grow rapidly while also delivering direct value to clients and partners.

She believes Sunrock stands apart because it continuously anticipates rather than reacts. Whether the topic is EMS, BESS, flexible energy solutions, or grid congestion, teams collaborate to translate complexity into practical, forward-looking solutions.

Proud Moments in a Fast-Changing Environment

Instead of pointing to a single project, Liselotte is most proud of the transformation she has witnessed since joining Sunrock. The company expanded into new countries, reshaped teams, adjusted to shifting market realities, and evolved its business model beyond standard roof lease projects.

Reflecting on this period, she says: “I’m proud of the flexibility and creativity we have showed and how we adapted our business model.” For her, these experiences highlight the pace and dynamism of both Sunrock and the wider energy sector. “Our teams adapt fast and translate complexity into practical solutions. I think this allows Sunrock to move at the pace of the energy transition instead of being held back by it.”

A Deep Personal Connection to the Mission

Liselotte’s motivation comes from the knowledge that her work contributes to a cleaner and more future-proof energy system. She enjoys being hands-on and thinking critically, as well as constantly looking for ways to improve processes and outcomes. She feels energised by colleagues who are ambitious, open, and curious, and who share the commitment to move the energy transition forward.

Looking Ahead With Curiosity and Confidence

Looking ahead, Liselotte feels especially inspired by Sunrock’s more complex and multidisciplinary projects. These are the projects that combine multiple assets and services, require creative structuring, and bring technical, legal, financial, and commercial teams together.

As she puts it: “It’s really inspiring and valuable to help build something new, rather than simply applying an existing template. The space to rethink, improve, and refine; asking how we can make a project, process, or a contract more robust and future- proof, is something I really enjoy.”

Together with our Sunrock team, Liselotte looks forward to continuing to shape innovative solutions that meet the needs of clients and the realities of a decentralised energy system.

Panattoni entrusts Sunrock with the photovoltaic equipment of its new logistics site in Ormes, France

Paris, 29 January 2026 – Sunrock, the European leader in photovoltaic solutions for logistics real estate, announces the extension of its partnership with Panattoni—one of the world’s leading industrial real estate developers—to the French market. Following successful collaborations in the Netherlands and Germany, the two companies are now combining their expertise to develop large-scale solar projects, starting with a first site in Ormes. This project reflects Panattoni France’s ambitious decarbonization strategy.

A strategic partnership in service of decarbonization

Installing photovoltaic panels on the roofs of logistics buildings transforms previously unused surfaces into genuine sources of renewable energy—available for tenants and surrounding communities. For Panattoni, the objective is twofold: 

• Significantly reduce the carbon footprint of its buildings throughout their lifecycle
• Offer clients real estate solutions aligned with their CSR commitments

“These projects generate a virtuous circle at the territorial level: each logistics warehouse becomes an active link in the local energy chain. This strategy is fully aligned with national energy transition objectives, meeting regulatory requirements (Climate & Resilience Law) as well as the increasing expectations of territories, clients and investors regarding environmental responsibility,” explains Llorenç Jalle Garrido, Technical Director, Panattoni France.

Commitment beyond regulatory obligations

Since establishing its presence in France more than four years ago, Panattoni has committed to reducing its carbon footprint and environmental impact beyond regulatory requirements. While regulations mandate photovoltaic coverage of 30% of usable roof space, the company far exceeds this threshold. A signatory of the Afilog charter since 2021—which requires at least 50% roof coverage—Panattoni commits to surpassing regulatory thresholds and aims for 100% coverage of usable roof space. Two additional solar projects between the two partners are expected to be announced in 2026.

“Sunrock’s expertise in the European market enables us to support Panattoni’s ambitions with a turnkey approach tailored to French specificities. We manage the entire value chain: engineering, regulations, insurance, grid connection and local energy resale. Our objective: develop several dozen MWp per year in France,” states Romain Bajas, Project Developer at Sunrock France.

Renewable energy serving local communities

Installing rooftop photovoltaic panels on logistics platforms transforms unused areas into renewable energy sources for their territories. The electricity produced will be partly sold to building tenants and nearby businesses through collective self-consumption operations.

The Ormes site (total capacity: 1.8 MWp) produces the equivalent of the annual electricity consumption of around 500 French households. This logistics site thus becomes an active contributor to the local energy production ecosystem.

A competitive advantage for clients

Equipping logistics platforms with photovoltaic panels and sharing the generated electricity with tenants directly contributes to reducing the buildings’ carbon footprint while improving energy performance, a key factor in obtaining BREEAM certification.

This also represents a competitive advantage for Panattoni’s clients—both users and investors. These installations help reduce energy costs while ensuring high-performing real estate assets aligned with their own CSR commitments, adding value in the eyes of partners, employees and end clients.

To address the challenges of grid congestion at the eCommerce distribution centre in Ede, AS Watson Health and Beauty Benelux has partnered with Sunrock. A reliable and sustainable energy solution is needed to support the growth plans of the international health and beauty retailer.

As part of the collaboration, Sunrock developed an innovative, fully integrated behind the meter energy solution. By combining rooftop solar panels with battery storage controlled by an intelligent Energy Management System EMS, a stable, comprehensive solution is created that supports AS Watson’s sustainability ambitions. It not only safeguards the reliability of today’s energy supply, but also provides the foundation for future expansion and sustainable growth for AS Watson, known for retail brands such as Kruidvat and Trekpleister.

AS Watson enlisted Sunrock, one of Europe’s leading developer of integrated clean energy solutions for logistics and industrial sites, to support the mechanisation rollout at the eCommerce distribution centre in Ede. The facility, where all online customer orders for Kruidvat and Trekpleister are processed, was faced with rising energy consumption while simultaneously being restricted by grid congestion. To overcome this challenge, an investment in the local energy infrastructure was required. The behind the meter solution enables the distribution centre to expand its operations without being limited by grid congestion. The battery system absorbs peaks in electricity consumption and maximises the use of solar energy within AS Watson’s operations. All of this is fully controlled by Sunrock’s EMS platform. The complete behind the meter solution consists of:

• 300 kW / 929.5 kWh Battery Energy Storage System (BESS), and a 0.8 MWp solar system, converted from grid export to local consumption to optimise the use of solar energy,
• advanced Energy Management System (EMS), enabling operational growth despite grid constraints, maximising on site use of renewable energy, and ensuring a future proof energy supply during peak periods.

“With the deployment of automation and robotics, we make work easier and more efficient while increasing customer satisfaction. A reliable energy supply played a crucial role in this, and in line with our sustainability goals we wanted to source as much of it as possible from fossil free energy. After identifying grid congestion as a major challenge, the Sunrock team developed and implemented an innovative energy solution that fully leverages the PV system, delivering a sustainable and efficient energy supply perfectly aligned with the site’s specific constraints and needs”, says Alexander Webhofer, Head of Supply Chain Online Business Benelux at AS Watson.

“This is an excellent example of how we help our clients stay ahead despite the limitations of the electricity grid. By integrating storage, solar energy and intelligent energy control, we have created a flexible and robust system that unlocks both energy independence and long term value”, says Karlijn Elias Peters, Managing Director Netherlands at Sunrock.

Vincent Meulendijks, Project Developer at Sunrock, adds: “From day one, we worked closely with AS Watson to map out the full scope of the challenge. It is great to see how our customised energy solution enables the expansion of AS Watson’s operations through a combination of sustainable solar energy and battery storage. We thank AS Watson for their trust and the successful collaboration.”

Sunrock is the Dutch market leader in logistics-based solar roofs. “That market is no longer focused on maximising PV,” says Karlijn Elias-Peters. “It’s driven by integrated energy solutions.”

You started last year as managing director of Sunrock Netherlands…

“I’ve been working here for a while, starting in 2021 as a Project Developer and becoming Head of New Markets in 2024. The big question was where we would expand next, besides the Netherlands, Germany, and France. Shortly after, we decided to focus on the countries we were already serving. The market was changing rapidly, and I was asked to lead our activities in the Netherlands and help our clients with new energy challenges.’

 How is Sunrock doing in the Netherlands?

“Good. Sunrock grew its business by installing solar roofs for logistics and industrial companies. We’ve installed approximately 600 megawatts of PV at around 250 locations, making us the market leader in this field and enabling us to build many strong customer relationships. However, the time of simply installing a lot of solar panels on roofs as quickly as possible is over; a new era has dawned.”

What era?

“The energy issue has changed and become part of our customers’ business operations. How can I get more solar power from my own roof? Can I get a grid connection or upgrade it? I want to electrify, but is that even possible? How can I use solar power to charge my trucks? These are examples of current questions that companies are grappling with. In line with this, we are focusing more on existing customers, helping them with long-term solutions.” 

Grid congestion and increasingly negative energy prices are the problem…

” The entire solar sector is experiencing this, including us. But our assets are manageable through an energy management system (EMS). Consider, for example, increasing local consumption, optimising with a battery, and making smart use of the various energy markets. We have our own energy trading team that maximises solar power yields. Integrated, flexible solutions for generation, storage, and consumption are the future. This will provide new market momentum.”

Logistics property owners recognize the importance of this?

“The market is evolving. Some haven’t even started looking at it yet. However, you’re seeing a growing number of interested parties, for example, because they want to go green, control their own energy consumption, or ensure the continuity of their properties by making them more sustainable. We can fully support them in this process.”

Installing a battery is now standard practice for you?

“That’s also gaining momentum. Sunrock is analysing the best options together with customers. We help companies optimise their local energy consumption; a battery often plays a role here. We also sometimes discuss proactive investments, for example, with a view to the future electrification of transport, which we also support. Smartly controlling your energy system with an EMS is crucial in this regard, and it’s something we’ve invested heavily in ourselves.”

Sunrock’s work has become much more complex…

“Sunrock experienced enormous growth by installing solar panels on roofs. However, that’s no longer the norm. There’s been a shift toward energy systems that combine all sorts of technologies and functionalities. The Dutch market has become one of integrated energy solutions. That’s a lot more complex, but also much more exciting. The demand for flexible energy systems will only increase in the coming years. Those who invest now will be at the forefront later.”
