Crane - 250 Wp PVT Hybrid Module - Photovoltaic & Solar Thermal Panel
The PVT Hybrid Module 250 Wp combines photovoltaic power generation with solar thermal technology, offering a dual-function solution for electricity and hot water production. This innovative module features a photovoltaic layer to capture solar radiation, converting it into electricity and heat. Integrated absorbers behind the solar cells effectively transfer this heat to a carrier fluid, such as propylene glycol, to warm water. The continuous heat removal maintains optimal cell temperatures, enhancing photovoltaic efficiency. Electrical outputs conform to standard test conditions with irradiance levels of 1000 W/m², air mass of 1.5, and a cell temperature of 25°C. The system is designed for locations without grid access, making it suitable for remote or off-grid applications. Its high efficiency and reliability make it an ideal component in both domestic and industrial energy systems.

This module performs simultaneously two functions – generates electricity and heats water. It is a combination of a photovoltaic module for electricity generation and solar thermal collector.
The face of the PVT panel absorbs solar radiation and produces electricity and warmth. A highly effective absorber, integrated in the back of the solar cells takes away the heat and by means of a heat carrier (propylene glycol) warms water. And thanks to the heat removal, the photovoltaic cells are constantly cooled, thus increasing their performance and working with optimal efficiency.
