BIPV

A group of scientists in China constructed a specialized compartment to test the thermal breakage and fallout of BIPV façades under enclosure fire conditions. They examined three different types of BIPV modules and found that tempered-glass PV panels exhibit superior thermal and mechanical resistance to breakage.

A new report from the Netherlands Enterprise Agency (RVO) estimates that building façades could offer up to 36 GW of technical solar PV potential, representing a significant but largely untapped resource. However, high costs, regulatory complexity, and lower performance compared to rooftop systems limit widespread adoption, currently making façade PV a niche solution for specific building types.

Building-integrated PV (BIPV) company ClearVue Technologies is a step closer to commercial deployment of its metal-backed solar panels after securing International Electrotechnical Commission (IEC) certification for the integrated rooftop system.

Researchers in the United Kingdom have developed a smart window that combines switchable polymer-dispersed liquid crystal with integrated PV cells, offering controllable transparency and electricity generation. The system balances light, heat, and solar protection while maintaining high visual quality and stable performance, according to its creators.

Researchers in Hong Kong Hong Kong fabricated a thermochromic bifacial photovoltaic glazing system prototype that passively regulates solar heat gain while harvesting energy from both sides. Experiments and simulations showed it significantly reduces cooling loads and indoor temperatures while boosting electricity generation.

German manufacturer Ehret has launched SolarSlide, a sliding shutter with integrated PV modules developed with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). It provides solar shading while generating electricity for residential and commercial facades.

Germany’s SolarEnvelopeCenter project has launched a web-based planning guide for building-integrated photovoltaics (BIPV), offering standardized design solutions for roofs and facades that comply with building codes and industry standards.

Australian researchers developed a low-cost reflective coating for semi-transparent solar roof tiles that lowers surface temperatures by up to 20 C and boosts power output by up to 11.7%. Simulations across five global cities showed energy savings of up to 5.85%, highlighting the coating’s strong potential for improving both building cooling efficiency and solar performance in BIPV systems.

Fraunhofer CSP researchers in Germany are developing printing and color technologies to make conventional silicon PV panels less visible when installed on building façades, roofs, and balconies.

Spanish building-integrated PV (BIPV) manufacturer Onyx Solar is delivering a custom building integrated PV system featuring almost 1,800 solar glass ‘louvres’ designed to help power Australian tech giant Atlassian’s new 39-storey headquarters in downtown Sydney with 100% renewable energy
