Introduction
Imagine transforming two massive, 50-year-old satellite antennas, each resembling a flying saucer with a diameter of 32 meters (105 ft), into a state-of-the-art solar installation. Nestled 1,000 meters above sea level in the picturesque Swiss Alps, this groundbreaking project leverages the unique advantages of these obsolete structures. With a peak output of 117 kW, the Luek site now harnesses the power of 307 solar panels, 156 P850 optimizers, and 1 SE100k inverter.
This innovative solar installation is a testament to the vision and ingenuity of the CKW Group. By repurposing the satellite antennas, CKW has unlocked a host of strategic benefits. The antennas' ability to track the sun throughout the day ensures optimal energy production, significantly outperforming conventional fixed roof systems. This dynamic tracking capability not only maximizes solar exposure but also allows the antennas to be angled away from adverse weather conditions, protecting the installation and ensuring consistent energy output.
Located atop the mountains, these antennas capture unobstructed sunlight, even during winter months, avoiding the mist and shading typical in lower-lying areas. This optimal positioning ensures higher efficiency and reliability in solar power generation. Each antenna can produce enough electricity to meet the energy demands of 25 homes, showcasing the project's impressive capacity and impact.
The CKW Group’s initiative addresses several real-world challenges, including shading and varying weather conditions. Their expertise in managing these factors has resulted in a safe, reliable system that sets a new standard for solar energy projects. Despite the lack of comparable projects in Europe, CKW has successfully navigated these hurdles, demonstrating the feasibility and benefits of using obsolete satellite antennas for clean energy generation.
This project not only enhances Switzerland's energy security but also paves the way for similar innovations worldwide. By repurposing existing structures, CKW Group highlights the potential for sustainable solutions that are both economically and environmentally beneficial.
Technical Specifications and Features
The innovative solar installation at the Luek site is comprised of 307 solar panels, 156 P850 optimizers, and a single SE100k inverter, all working in harmony to achieve a peak output of 117 kW. Each component plays a crucial role in maximizing the efficiency and reliability of the system.
The 307 solar panels capture sunlight and convert it into electricity, while the 156 P850 optimizers ensure each panel operates at its maximum potential by mitigating the effects of shading and panel mismatch. The SE100k inverter then converts the DC electricity generated by the panels into AC electricity, which can be used to power homes and businesses.
One of the standout features of this installation is the ability of the satellite antennas to track the sun throughout the day. Unlike fixed roof systems, which are limited to a static position, these antennas can rotate to follow the sun's trajectory, ensuring optimal exposure and energy production from sunrise to sunset. This tracking capability significantly boosts the system’s efficiency and output.
Additionally, the antennas offer innovative weather protection. By adjusting their angle, they can be positioned to avoid harsh weather conditions, such as strong winds or heavy snowfall, thus safeguarding the installation and maintaining consistent energy production. This dynamic adaptability makes the system not only more efficient but also more resilient, ensuring long-term reliability and performance.
Overcoming Challenges
The project to convert obsolete satellite antennas into a solar installation at the Luek site faced several unique challenges, primarily due to the lack of comparable projects in Europe. This pioneering effort required innovative solutions and meticulous planning to ensure success.
One major challenge was managing shading and varying weather conditions. The mountainous location, while advantageous for sunlight exposure, introduced complexities such as fluctuating weather patterns and potential shading from the terrain. To address this, the installation utilizes 156 P850 optimizers, which help mitigate the impact of shading on individual panels, ensuring each one operates at peak efficiency. The tracking capability of the antennas also plays a crucial role, as they can adjust their orientation to maximize sunlight exposure and minimize shading throughout the day.
Another challenge was ensuring the system's reliability and safety. Given the absence of similar projects for reference, CKW Group had to prioritize creating a robust and dependable system. The ability of the antennas to adjust their angle for weather protection adds a layer of resilience, allowing them to withstand harsh conditions such as strong winds and heavy snowfall. This adaptability not only protects the installation but also maintains consistent energy production, demonstrating the importance of a safe and reliable system.
Environmental and Economic Benefits
The transformation of satellite antennas into a solar installation at the Luek site has significant environmental and economic benefits. Environmentally, this project contributes to increased solar energy production, reducing reliance on fossil fuels and significantly lowering carbon emissions.

Globally, there are several inspiring examples of this trend. Cold War satellite imagery is being repurposed for ecological research, helping scientists identify and protect areas of high ecological value. In the United States, former coal plants are being converted into renewable energy sites, turning sources of high pollution into clean energy hubs. These initiatives not only make use of existing infrastructure, saving time and resources, but also significantly reduce construction pollution and environmental disruption.
In Ireland, a similar approach could be taken with the numerous decommissioned windmills and industrial sites scattered across the country. These structures, often located in windy and sunlit areas, could be repurposed into hybrid renewable energy sites combining wind and solar power. This would maximize energy production while preserving historical landmarks and reducing the need for new construction.
Utilizing existing structures for renewable energy projects offers multiple benefits. It saves time and money compared to building new facilities from scratch. It also minimizes environmental impact by reducing construction-related pollution and land use. Moreover, repurposing infrastructure promotes sustainability by extending the life and utility of existing assets.
These innovative projects underline the importance of thinking creatively about renewable energy solutions. By turning obsolete structures into functional, green energy sources, we can make significant strides in reducing our carbon footprint and achieving energy security. The Luek site project is a powerful example of how imaginative engineering and sustainability can go hand in hand to address our energy challenges.
