Consolar Solare Energiesysteme GmbH
Consolar Solare Energiesysteme GmbH is a pioneering German engineering company that specializes in the development and manufacturing of highly efficient solar thermal systems and innovative heating technologies. Headquartered in L?rrach, Germany, and founded in 1994, Consolar has established itself as a technological leader in the renewable heating sector. The company's core mission is to create sustainable and highly effective heating solutions that maximize the use of solar energy, significantly reduce reliance on fossil fuels, and provide long-term energy security and cost savings for homeowners.
Unlike companies focused solely on photovoltaics (PV) for electricity generation, Consolar's expertise lies in solar thermal technology?using the sun's energy to generate heat for hot water and space heating. Their systems are renowned for their high efficiency, particularly in the northern and central European climates, where they are designed to deliver exceptional performance even during colder months with less intense sunlight. Consolar primarily operates on a B2B model, distributing its products through a network of trained professional installers and heating engineers.

Core Business and Technology Philosophy
Consolar's business is built on a philosophy of "solar-optimized heating." This means designing complete, integrated systems where every component is engineered to work together to capture, store, and distribute solar heat with minimal loss. The company is particularly known for its advancements in two key areas: high-performance evacuated tube collectors and highly stratified thermal storage tanks. This combination allows their systems to achieve a very high solar fraction, meaning a large percentage of a building's total annual heating and hot water demand can be met by solar energy alone.
Key Products and Services
Consolar offers a portfolio of interconnected products that form complete heating systems, designed for both new buildings and retrofitting older ones.
1. High-Performance Solar Collectors
Consolar's collectors are the heart of their systems and are engineered for maximum energy yield.
- TUBO Series Evacuated Tube Collectors: This is Consolar's flagship collector technology. Unlike flat-plate collectors, evacuated tube collectors consist of parallel glass tubes with a vacuum layer for insulation, similar to a thermos flask. This design drastically reduces heat loss to the surrounding air, making them exceptionally efficient, especially in cold or windy conditions. The TUBO collectors are known for:
- CPC Reflector (Compound Parabolic Concentrator): A highly reflective, weather-proof mirror is placed behind the tubes to capture diffuse and indirect sunlight and focus it onto the absorber, significantly boosting energy yield.
- High-Temperature Operation: They can achieve higher temperatures than flat-plate collectors, making them ideal not only for domestic hot water but also for providing substantial support for central heating systems.
2. Intelligent Thermal Storage Solutions
Efficiently storing the captured solar heat is as important as collecting it. Consolar has developed highly advanced thermal storage tanks that are central to their system's performance.
SOLARUS Stratified Storage Tank: This is a highly insulated water tank designed to maintain strict thermal stratification. Hot water naturally rises, so the tank is engineered with special inlets and flow calmers to keep the hottest water at the top (for immediate use) and cooler water at the bottom, without the layers mixing. This ensures that the solar collectors can always feed into the coolest part of the tank, allowing them to operate at their highest efficiency.
COMO Stratified Storage Tank: A versatile storage tank that can integrate multiple heat sources, such as a solar thermal system, a heat pump, and a conventional boiler, all within one unit.
3. Integrated Hybrid Heating Systems
Consolar's most innovative products are complete hybrid systems that combine solar thermal with other renewable technologies.
SOLAERA? Hybrid System: This is a groundbreaking product that combines a high-performance solar thermal system with a compact, air-source heat pump. It is designed to provide 100% of a building's heating and hot water needs using only renewable energy.
- How it works: The solar thermal collectors provide the primary source of heat. When solar energy is insufficient (e.g., at night or on very cloudy winter days), the integrated air-source heat pump switches on. The system is intelligently managed to always prioritize the use of direct solar heat, using the heat pump only as a backup. This results in a much higher overall system efficiency (Seasonal Performance Factor - SPF) than a standalone heat pump.
INTERSOL System: This is a highly efficient and compact solar heating system designed specifically for providing the majority of the hot water and heating needs for single-family homes. It pairs the TUBO collectors with a COMO or SOLARUS storage tank for a complete, integrated solution.
4. PVT (Photovoltaic-Thermal) Collectors
Bridging the gap between electricity and heat generation, Consolar also offers PVT collectors.
- PANTHERA PVT Collector: This is a hybrid collector that generates both electricity (like a standard PV module) and heat simultaneously from the same surface area. The back of the PV module has a heat exchanger that captures the waste heat generated by the solar cells. This process has a dual benefit: it provides useful thermal energy for hot water or heating, and by cooling the PV cells, it increases their electrical efficiency. This technology is ideal for applications where roof space is limited.
5. System Controls and Services
To manage these complex systems, Consolar provides intelligent control units that optimize the interaction between collectors, storage tanks, and backup heaters. The company also provides extensive planning support, training, and technical assistance for its network of professional installers to ensure every system is designed and commissioned for optimal performance.
