Unscramble the Blue Letters

Besides looking nice, these integrated solar cells come along with two more important benefits. Do you remember the solar cell attaehcd to a roof I showed before? In this case, we install the roof first, and as a second layer, the solar cell. This is adding on the itlasaonlitn costs. In the case of integrated solar cells, at the site of construction, only one element is installed, being at the same time the envelope of the building and the solar cell. Besides svinag on the installation costs, this also saevs resources, because the two fncotiuns are cinobmed into one element.

Besides looking nice, these integrated solar cells come along with two more important benefits. Do you remember the solar cell attached to a roof I showed before? In this case, we install the roof first, and as a second layer, the solar cell. This is adding on the installation costs. In the case of integrated solar cells, at the site of construction, only one element is installed, being at the same time the envelope of the building and the solar cell. Besides saving on the installation costs, this also saves resources, because the two functions are combined into one element.
