SolReina’s patented photo voltaic window wins greatest protected invention award in Spain – pv journal International


The home windows, composed of glass-glass BIPV panels with thermal and acoustic insulation, are designed to be used in constructing exteriors. They can produce between 150 and 225 W/m2. While presently manufactured and marketed in Spain, it could quickly be out there in Germany.

Spanish BIPV producer SolReina gained the award for Best Utility Model for it BIPV window of the Spanish Patent and Trademark Office’s Best Invention Protected by Industrial Property Awards.

Competing towards 153 different competing initiatives, José Reina García introduced his invention from the Asturias-based building firm Asturbath Reformas (SolReina Group): a photo voltaic window with a PV panel as a folding and adjustable shutter, able to effectively producing electrical energy from daylight.

Reina spoke pv journal concerning the photo voltaic window, which he says “past the same old definition of a window.”

The home windows are composed of BIPV glass-glass panels with thermal and acoustic insulation and are designed to be used in constructing exteriors. They use high-security tempered glass and “obtain wonderful resistance towards mechanical stress, akin to hail, and modifications in temperature,” stated Reina.

The entrance half has tempered photo voltaic glass with excessive transmissivity, low reflectivity and low iron content material. They use high-efficiency crystalline silicon cells to transform the power of photo voltaic radiation into direct electrical power. Each cell is electrically labeled to optimize the module’s efficiency.

The cell circuit is laminated between two sheets of polyvinyl butyral (PVB), which has anti-aging properties, as an encapsulant for defense towards humidity, stability towards ultraviolet (UV) rays and electrical insulation.

The again of the PV modules consists of tempered glass with a low iron content material.

The junction field, with IP67, is fabricated from excessive temperature resistant plastic and comprises terminals, connection terminals and bypass diode. These modules are supplied with cables of symmetrical size, with a diameter of 4 mm copper cross-section and really low contact resistance, designed to realize minimal loss as a consequence of dropping of voltage.

The home windows can regulate their orientation and undertake completely different steady positions, for instance, relying on the angle of photo voltaic radiation to maximise the gathering of photo voltaic power. It may also be absolutely folded ready parallel to the wall to supply much less resistance to wind, rain or on days with excessive radiation and excessive temperatures.

The home windows may also be tailored to completely different sizes, shapes and architectural designs, measured in keeping with the precise wants of every undertaking, and constructed with completely different BIPV panel finishes. The body is fabricated from aluminum.

“In common phrases, an ordinary photo voltaic window generates roughly between 150 and 225 W/m2,” stated Reina, emphasizing that, “It has been confirmed that this window can scale back of the necessity for electrical air con as much as 80% of the times and produces 15% extra photovoltaic power than a rooftop set up.”

The home windows are presently produced and marketed in Spain, however the producer has prolonged the patent to Germany with the intention “not solely to broaden our market share, but in addition to determine strategic collaborations with European companions.”
