Solar thermal heats the water, photovoltaics provide the electricity.

Solar energy forms the basis of most energy sources on the planet. In Czech conditions, we have 950–1100 kWh/m² of solar radiation per year available, which represents a huge potential for direct use.
Solar thermal systems convert this energy into heat for DHW heating and space heating, while photovoltaic systems convert it into electricity. A correctly designed system then saves not only your wallet but also nature.
Converts solar radiation into heat with an efficiency of up to 80 %. Most commonly used for heating domestic hot water, auxiliary heating, or pool heating. The system consists of solar collectors, a hot water storage tank, a pump station, a controller, and other parts.
Converts solar radiation into electrical energy using photovoltaic panels with an efficiency of around 20 %. You can use the generated electricity directly in the household or store it in batteries. The system consists of PV panels, an inverter, batteries, and other components.
We design technology combinations to be efficient, reliable, and economical. If subsidy programs are available, our specialists will handle all the formalities for you.
We have specialized in solar technologies since 1992 as one of the first in the Czech Republic. Over 30+ years, we have grown into a leader with our own development center, testing department, 180 employees, and deliveries to 46 countries worldwide. We are not a fashion trend, but a certainty that will be here for you even in ten years.
We supply complete systems with perfectly matched components for the best possible performance. No shifting of responsibility between different companies; you have one partner for the entire project. From design to long-term service.
We don't do standardized solutions. Even two identical houses might need something different. We design the system for your house exactly according to your needs. We assess everything individually, and if we see that a solution is not cost-effective for you, you will be the first to know.
We know you are investing in technology for 20+ years, not just for a few seasons. Thanks to our long tradition and in-house production, you have the certainty that you will be able to get any necessary spare part even in decades. You don't risk an expensive replacement of the entire system due to the unavailability of components.

Solar thermal collectors convert solar energy into heat with an efficiency of up to 80% and are primarily intended for heating water, pools, and auxiliary space heating. Photovoltaic systems convert solar radiation into electricity with an efficiency of around 20%. For DHW heating, a thermal system is significantly more efficient – it needs a much smaller area than photovoltaics with electric heating.
Yes, thermal and photovoltaics complement each other. Thermal is most efficient for DHW heating and heating support, while photovoltaics cover the household's electricity consumption. By combining both systems, maximum energy self-sufficiency and savings can be achieved.
The return on investment for a solar thermal system is usually 8–10 years, and for photovoltaics 8–12 years. The specific payback period always depends on the consumption of domestic hot water and electrical energy in the building, current energy prices, the quality of the design and installation, and the level of consumption optimization.
Yes, but with lower efficiency. Even in cloudy weather, collectors and panels generate energy, although the output drops. A well-designed system accounts for these fluctuations and effectively utilizes the available energy.
Yes, we provide warranty and post-warranty service across the Czech Republic. We have our own service network, so we won't leave you waiting long. If intervention is necessary, a technician usually arrives within 3 days.
