Description

Technical field

[0001] The invention relates to modular photovoltaic systems that combine electricity generation with heat utilization, cooling, and intelligent control. It is suitable for roofs, facades, carports, or other open areas. Background / Problem statement

[0002] PV modules lose efficiency at high temperatures (approx. 0.4-0.5% / °C above 25°C). Waste heat is often left unused.

[0003] Climate change is causing temperatures to rise in Germany and Northern Europe. This leads to increased solar power generation, but also to a greater need for cooling in buildings. Directly using PV power for conventional air conditioning systems is inefficient.

[0004] Goal: To maximize energy yield through intelligent cooling, simultaneous heat utilization, and efficient summer cooling. Solution approach of the invention • Adaptive, intelligent cooling • Sensors monitor module temperature, outside temperature and building requirements. • Automatic switching between cooling the building or heat utilization. • Evaporation-based summer cooling • Integration of a passive evaporative cooler into the cooling circuit. • Cooling occurs without additional compression cooling, directly through evaporation of the cooling medium. • Multiple uses of heat • PV cooling + hot water + heating support + process heat (pools, heat pumps). • Optimized energy yield per square meter throughout the entire year. • Modular, plug-and-play channels • Plug-in channels for water or air circuits. • Easy retrofitting to existing PV systems or roofs. • Integration into smart home or building management systems • Automatic adjustment of cooling and heating flow to current demand. Advantages of the invention • Higher PV efficiency through cooling of the modules. • Summer cooling without air conditioning reduces electricity consumption. • Year-round use of roof space for electricity, hot water, heating, pools or process heat. • Easy retrofitting of existing PV systems through modular channels. • Adaptation to climate change: rising temperatures → higher energy efficiency and reduction of cooling requirements.
