WE INVEST IN SOLAR ENERGY BECAUSE OF
STRONG GROWTH POTENTIAL
The solar energy industry is experiencing explosive growth. According to the International Energy Agency, solar energy could provide one-third of the world's electricity by 2050. In addition to electricity, solar power is crucial in delivering renewable thermal solutions for industrial heating and cooling processes.
COST-EFFECTIVENESS
The cost of solar energy has been declining steadily over the past decade, and it is now competitive with traditional sources of energy in many parts of the world. This makes it an attractive option, increasing the demand for solar products and creating more investment opportunities.
ENVIRONMENTAL BENEFITS
Solar energy is a clean and renewable source of energy. By investing in and promoting solar energy, we can help reduce our reliance on fossil fuels and contribute to mitigating climate change, which is an increasingly urgent issue for governments, businesses, and individuals worldwide.
MATURE TECHNOLOGY
Solar technologies have come a long way and are now considered mature and proven technologies for generating electricity and heat. Both photovoltaic and solar thermal technologies have been in use for several decades, and as a result, they have significantly improved efficiency, reliability, and cost-effectiveness.
OUR SOLAR SUBSIDIARY: INDUSTRIAL SOLAR
Industrial Solar GmbH is a pioneer technology and solution provider of tailor-made solar energy solutions for solar heat and energy supply for industrial processes. In addition to its Fresnel collector, it offers a wide range of solutions to help the decarbonization of industries. As a one-stop shop, Industrial Solar provides turnkey installations to customers in several industries.
THERMAL
Solar thermal solutions can provide heating and cooling for industries.
PHOTOVOLTAIC
Generating electricity with PV is the cheapest form of electricity production.
ENERGY CONCEPT STUDIES
Energy concept studies help clients find the optimal solar energy solution tailored and optimized for them.

Fresnel Collectors
The flagship product of Industrial Solar is the Fresnel collector. It is a unique technology for industrial applications. This concentrating solar thermal collector can provide heat up to 400°C and generate steam. It is also suitable to be combined with absorption chillers to utilize excess heat in cooling solutions. In fact, Industrial Solar is the first company worldwide to provide solar steam commercially for both heating and cooling. Overall, it is an ideal technology for consistently sunny regions, where industrial energy demand is increasing.
WE INVEST IN WATER BECAUSE OF
ADDRESSING A CRITICAL NEED
Clean water is a fundamental human need, and access to clean water is also essential for many industries, including agriculture, energy, and manufacturing. Innovative, sustainable, and cost-effective clean water solutions exist, and they are a key investment opportunity.
COMPETITIVE ADVANTAGE
Investing in unique and patented clean water solutions is an attractive choice as more and more industries are looking to reduce their water-related costs while increasing their sustainability.
GROWING MARKET DEMAND
The market for clean water solutions is expanding rapidly, as the demand for sustainable water solutions increases. Since climate change continues to affect the world's water supply, the need for sustainable solutions will only grow.
ENVIRONMENTAL BENEFITS
Water pollution and scarcity are major environmental issues with far-reaching consequences. Sustainable water solutions help conserve water resources, reduce water pollution, and minimize harmful chemicals and energy use.
OUR WATER SUBSIDIARY: SOLARSPRING
SolarSpring GmbH is an equipment manufacturer of innovative membrane-based water treatment technology for industrial customers. The company is a pioneer in membrane distillation for industrial wastewater treatment. This technology allows clients to reuse process liquids or recover valuable raw materials such as gold, silver, or other costly resources.
Membrane Distillation
Membrane Distillation can treat wastewater to obtain clean water and recover valuable resources from wastewater.
Drinking Water Treatment
SolarSpring’s system guarantees a reliable and safe water supply from dirty and microbiologically contaminated water sources without using chemicals.
Ultrafiltration
Ultrafiltration utilizes a semipermeable membrane as a physical barrier. It is an efficient and low energy-consuming process that retains 99 % of microorganisms, bacteria, and viruses.
Membrane Distillation
Membrane Distillation is an innovative water treatment system that can recover up to 95% of the process water and reduce the wastewater volume. The membrane distillation system separates hot and cold feed streams with a water-repellent membrane. Moreover, valuable by-products from the waste stream can be recovered and recycled too. A unique aspect of this technology developed by SolarSpring is that it can be thermally driven using waste heat or can be combined with other heat sources such as solar thermal collectors.
