Design and efficiency

 A unique structure of its kind, RA works as a self-supporting roof designed to produce both electrical and thermal energy.






35% Electrical Power


The RA photovoltaic cells are cooled down by a fluid passing through the panel, hence a higher electrical efficiency production compared to a traditional pv module which loses efficiency when cells are overheated.



35% Thermal energy (+ Heat pump)

For each electrical kw produced almost the quadruple in thermal energy

Three solutions in one third of the space

See power and simplicity


The RA modules, looking like self-supporting beams designed to withstand snow load, form a solar roof that can be treaded. 

In just one third of the space the result is a real roof and two plants

(electrical and thermal energy installation).
