𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗩𝗶𝘀𝗶𝘁 𝘁𝗼 𝗖𝗵𝗶𝗹𝗲 – 𝗙𝗼𝗰𝘂𝘀 𝗼𝗻 𝗘𝗻𝗲𝗿𝗴𝘆 𝗘𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝗰𝘆 𝗮𝗻𝗱 𝗦𝘆𝘀𝘁𝗲𝗺 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 🔧💫

As part of our project for the European Southern Observatory (ESO) in Chile, Werner and Max recently visited the La Silla site to assess the existing infrastructure for the cooling, heating, and hot water supply – and to define the next steps for improving energy efficiency.

The plan includes the implementation of new, automated systems to reduce energy consumption, along with the integration of a photovoltaic system – enabling the direct use of solar energy on site.

In close collaboration with the client, key functions and safety mechanisms were aligned – paving the way for a resilient and future-ready system at one of the most extraordinary locations on Earth. 🌟🌎

☀️ Solar Energy for Hospitals: Sustainable Hot Water Solutions 🌡️

Hospitals have a high demand for hot water—essential for cleaning and patient care. Solar thermal energy offers an eco-friendly and cost-effective solution:

✔️ Cost Savings: Reduce energy costs and fossil fuel dependence.
✔️ Eco-Friendly: Lower CO₂ emissions help meet climate goals.
✔️ Reliability: Durable, low-maintenance systems ensure a steady supply.

🌍 With extensive experience, we support you from planning to maintenance. One highlight: the hospital in Managua, Nicaragua, where our solar system provides both hot water and cooling.

A direct link between research, plant construction and operation: the district heating plant in Graz, Austria. The plant - built by SOLID - supplies most of the city's district heating, while different collector types are operating under real conditions.

💡𝗦𝗰𝗶𝗲𝗻𝗰𝗲: Unique field test of ten different collector types from seven manufacturers, including flat plate, parabolic-trough and heat pipe collectors.

🔧 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 & 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆: ESCo operation with heat supply to the local utility. The plant has a nominal heating capacity of 5 750 kW.

🌱 𝗘𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁: Solar hot water supply for around 8 000 citizens of Graz. More than 740 tons of CO2 are saved each year.

The test field allows the evaluation of collector performance and to constantly improve quality and increase efficiency. A win-win effect for solar research and industry.🙌

💡Yes? Why not consider using a heat pump?

SOLID offers in cooperation with TIGI both thermal driven and electrical driven heat pumps for applications up to 120°C. We are independent of manufacturers and offer you an all-inclusive service package from concept over design to engineering and installation, commissioning and operation. We also combine heat pumps with other components like solar thermal and energy storage and implement intelligent control systems.

Do not hesitate to get in touch with us if you are interested!🙌

🌍🚀 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀 𝗶𝗻 𝗙𝗼𝗰𝘂𝘀: 𝗦𝗵𝗮𝗽𝗶𝗻𝗴 𝘁𝗵𝗲 𝗙𝘂𝘁𝘂𝗿𝗲 𝗼𝗳 𝗦𝗼𝗹𝗮𝗿 𝗘𝗻𝗲𝗿𝗴𝘆 🌞🔋

Innovation plays an important role at SOLID. Through continuous research and development, we're working to harness the full potential of solar energy and to promote sustainable solutions. Our dedicated R&D team (Picture 1) strives to make solar energy more efficient and environmentally friendly every day.

Here’s a look at some of our key projects driving renewable energy forward:

💡 𝗧𝗿𝗲𝗮𝘀𝘂𝗿𝗲 𝗣𝗿𝗼𝗷𝗲𝗰𝘁: An EU-funded initiative focused on advancing Pit Thermal Energy Storage (PTES) technology, combining research and practical solutions for safer, cost-effective energy storage. We’re proud to be a demonstrator with our 𝗕𝗶𝗴𝗦𝗼𝗹𝗮𝗿 𝗣𝗮𝗻𝗰𝗲𝘃𝗼 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 and recently visited an underground storage tank in Hechingen (Picture 2).

💡 𝗛𝗲𝗮𝘁𝗠𝗶𝗻𝗲𝗗𝗛: Funded by the European LIFE program, this project develops business models for integrating low-quality heat into district heating networks. We recently joined a general assembly in Zagreb to discuss progress and potential solutions.

💡 𝗦𝘂𝗻𝗣𝗲𝗲𝗸: A free, open-source tool for monitoring solar thermal systems, supporting quality assurance and efficiency assessment. It includes a pre-configured demo plant with one year of open measurement data from the district heating plant in Graz, Austria (Picture 3). We’re currently revising the software documentation and updating the tool’s website.

At SOLID, we don't just develop solar technology—we’re shaping the future of energy! 🌱🔋
