Research starts into creating bespoke solar panels for buildings

10 Apr 14 A new EU reseach project has been launched aimed at creating tailored solar facades at the click of a button.

The SmartFlex project aims to demonstrate how photovoltaic building elements can be individually designed and then manufactured on an industrial scale, all at the click of a button. Over the next three years, eight project partners seek to develop a technical solution that fulfils this aim.

“The intention is that architects will be able to use an intuitive piece of planning software to design solar modules that integrate into their buildings as desired,” said Paul Grunow, director of the Photovoltaik-Institut Berlin in Germany. For example, the glass module elements could be round or triangular. “What makes the project unique is its aim to produce these remarkable solar elements using an automated process, reducing manual operations to a minimum. Such an approach has never been seen before as, to date, only standard modules have been manufactured in bulk and customised solar products have always been painstakingly produced by hand. SmartFlex is striving to find a way of manufacturing modules on a large scale using an extremely smart and flexible process that makes even tailored solar elements fully affordable.”

The project is developing a prototype production line capable of manufacturing photovoltaic modules in accordance with architects’ individual requirements. This involves directly transferring the data relating to the requested shapes, colors, sizes and materials of the solar elements from the planning software to the production line. Tests are being conducted on an office building with a facade measuring approximately 200m2 to ascertain which modules are particularly suitable for generating power when integrated into a building.

Around 20 different solar elements are being tested, including modules up to 3.5m in length with a maximum output of 750 watts peak. Furthermore, all of the mounting systems currently available on the market and a number of inverters are being put through their paces during field tests. The test building, which is the headquarters of project partner Glassbel, is located in Klaipeda, Lithuania.

“In addition to being generated on the roof, solar power can be produced on building facades. In fact, building-integrated photovoltaics has an enormous potential that is still far from being unlocked,” said  Dr Juras Ulbikas, senior researcher at the Applied Research Institute for Prospective Technologies (ProTech) in Vilnius, Lithuania, and coordinator of the SmartFlex project. “We are working on a plug and play solution for buildings that is easy to install and fulfils the needs of architects and installers. It’s an ambitious aim to say the least but I’m delighted that we’ve been able to secure such high-caliber partners to help us achieve our goal.”

The project partners include ProTech, Photovoltaik-Institut Berlin, glass manufacturer Glassbel, the international engineering company Mondragon Assembly, solar systems manufacturer Via Solis, the Swiss BIPV Competence Centre (SUPSI), the planning software developer Creative Amadeo and specialist renewable energy agency Sunbeam Communications.

The European Union’s Seventh Framework Programme for Research & Innovation is contributing €2.9m (£2.4m) of funding to the project.
