Cellafredda MAX · hybrid PVT panel
Cellafredda
A photovoltaic panel turns about a fifth of the light it receives into electricity. The rest becomes heat: it warms the cells, lowers their yield and is lost. Cellafredda recovers that heat for thermal cycles, cutting the demand for gas and other fuels.
Up to
1.500 W
Electricity and heat from the same panel
500 W electrical and 1000 W thermal combined: that is what Cellafredda MAX draws from two square metres of roof. A conventional photovoltaic panel, in the same space, stops at the electrical part.
Up to
80%
The highest energy density you can reach
The principle is stated outright: innovate the technology, do not add surface. From the first generation in 2010 to the fifth the footprint has not grown, but the power has.
Efficiency
75%
Of overall efficiency, electrical and thermal together
A photovoltaic panel turns about 25% of the light into current and loses the rest as heat. By recovering that heat, the panel's overall efficiency rises from 25% to 75% and beyond.

Five generations, fifteen years
The first Cellafredda patent dates from 2010. Every generation since has worked on the same constraint: more yield, same surface.
2010
Cellafredda Hybrid 250
First generation. The patent that introduces solar cogeneration.
2012
Cellafredda Hybrid 280
Second generation. Product refinement.
2015
Cellafredda 300 and 400
Third generation. The move to monocrystalline.
2020
Cellafredda HC
Fourth generation. Advanced efficiency.
2026
Cellafredda MAX
Fifth generation. Photovoltaic cells with ABC technology and very high yield.
Cellafredda technology, without compromise
- 01
Photovoltaic panel
The photovoltaic panel with high-efficiency ABC cells produces more energy due to cooling
- 02
Thermal conductive element
The thermal conductive element ensures rapid transfer of thermal energy from the photovoltaic cells to the absorber and optimizes the different thermal expansions of the various components
- 03
Heat absorber
The heat absorber is able to recover over 60% of the generated thermal energy, increasing the panel's total efficiency beyond 80% and significantly reducing thermal energy dispersion into the environment
- 04
Thermo-reflective insulation
The special thermo-reflective insulation minimizes heat losses
The four layers
Four stacked layers: the photovoltaic panel, the element that conducts the heat, the absorber that recovers it and the insulation that keeps it from escaping.
