In our part of the world, heating is a necessity. But in many cases, it’s still done in ways that are harmful to the environment, inefficient, and expensive. At Ritter Solartechnik, we bring solar heat to your home. Since 1988, we’ve been pioneers in solar thermal technology – and today, we’re one of the market leaders in this field. We develop and manufacture high-performance solar thermal systems in Germany: from compact units for private homes to large-scale systems for businesses, industry, and local heating networks – providing hot water, space heating, or process heat. In addition, we offer highly efficient pellet heating systems that use renewable wood and advanced technology to heat with minimal emissions.

We continuously develop our products and invest in training our team – because our goal is clear: to keep every carbon footprint as small as possible.

That’s why we’re especially proud that our commitment was recognized with the TOP 100 Innovation Award in 2021.

Our solar and wood heating systems help you reduce your reliance on fossil fuels, lower your energy bills, and cut CO₂ emissions. In short: we make heating greener. By using the sun as your heat source – delivering free energy right to your doorstep – you also gain independence from fluctuating fuel prices and uncertain supply chains. At Ritter Solartechnik, we pride ourselves on being agile in a world of slow-moving giants. We’re a reliable partner who brings sustainable heating to life – quickly, efficiently, and tailored to your needs.

The “Ritter collector” is regarded by experts in the sector as being synonymous with outstanding quality. Our customers also include renowned companies in the heating industry who rely on this outstanding quality. Apart from perfect compatibility the Ritter collector is also convincing thanks to its careful workmanship, durability, high-quality design and a good price/performance ratio. We offer product variety and flexibility in order to meet individual customer needs. Our customers have several choices in terms of design, gross surface area, number and length of vacuum tubes, hydraulic connections and manifold colours.

Large-scale solar thermal systems supply the energy for industrial plants whose production processes require industrial process heat. They reduce energy costs and improve the life cycle assessment (LCA). Ritter XL Solar achieves the necessary planning reliability by means of a guaranteed annual energy yield of the system. What is more, a large solar thermal system is also worthwhile for local and district heating networks and supplying communal facilities such as hospitals or swimming pools.

We evolve with the times ecologically consequent and go beyond collector mass manufacturing. We offer product variety and flexibility in order to meet individual needs of our customers. Ritter-Inside means customised collectors, high quality collector components, reliable mounting systems, as well as specialised R&D services. A highly qualified team of engineers and scientists undertake R&D activities in our Solar Technology Centre. We perform static pressure tests both for vacuum and flat-plate collectors, as well as for mounting systems to prove conformity with the wind and snow loads, according to the DIN EN ISO 9806 requirements.

Under our Paradigma brand, we offer environmentally friendly heating solutions for homes. At the heart of every solar heating system is a solar thermal collector. It captures the sun’s energy and provides reliable, eco-conscious hot water and heating support. Because our systems use water as the heat transfer medium, they can be seamlessly integrated into existing heating systems without the need for hydraulic separation. In modern homes with low heating demand, our solar thermal systems can even cover the majority of the heating load – making solar heat the primary energy source.
