Two technologies, one goal: maximum utilization of solar energy

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.

Types of solar technologies

Solar Thermal

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.

Photovoltaics (PV)

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.

How does solar thermal differ from photovoltaics?

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.

Is it worth combining both technologies?

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.

What is the return on investment?

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.

Do solar systems work in winter or during bad weather?

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.

What if the system breaks down? Do you offer service?

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.
