Most solar systems on houses are installed on top of roof tiles. This combination does not make much sense when you are building a new house or renovating your roof. Exasun produces integrated solar roof systems that are watertight, generate energy and also look great. The system has a life span of more than 30 years. The tiles are available in different colours for seamless integration into the building design. The smaller tiles make it possible to install panels on the entire roof. This maximises the electricity production.
