“The positive energy building is the global future.” Jean-Louis Esteves, CEO of TCE Solar, can barely contain his enthusiasm. For him, there is no doubt: the positive energy building, a building that produces more electricity than it consumes, is one of the saviors of the photovoltaic industry. The Grenelle has declared, on the basis of the European Directive on Energy Performance of Buildings: As of 2020, in France, all new buildings will be positive energy buildings. This obligation will enter into force for local authorities as of 2018.

And where there is positive energy, there is electricity generation, and, therefore, integrated solar photovoltaics. According to Jean-Louis Estteves, all of the players in this industry have their part to play. “The green building requires mastery of little-known technologies,” he explains. “There is still much progress to be made with regard to, firstly, solutions for integrated production of solar photovoltaic electricity. The industry must address this topic: improving what already exists, and inventing what does not yet exist.” In his opinion, it will then be possible to export this specific ‘French-style’ know-how worldwide for decades to come. Not to mention, all the buildings that will require renovation and rehabilitation. “It’s a challenge which we could look at as saving the planet,” says Jean-Louis Estteves.
