PHOTOVOLTAIC ROOF
Located in the heart of St. Helena, California, Corison Winery has always been known for its commitment to quality and the craftsmanship in the fabrication of their fine wines. Now, they will take lead in sustainability and design, by installing a photovoltaic glass in their roof that color-matches exactly the metal panel of the roof. It is a dark-green color that goes extremely well with its surroundings landscapes of Napa Valley.
Cathy Corison and William Martin, owners of Corison Winery, knew their roof was due for an update and also wanted to go solar.

The new roof design, with the colors of the original design are combining with the new energy efficient roof, Corison also wanted the solar modules to disappear as much as possible into the lines of the new roof.
Onyx Solar used their photovoltaic glass etching technology to color match the modules with the color of the new roof and to design the right technology mix needed to achieve the solar design.
The owners will benefit from the photovoltaic installation of 148 photovoltaic glasses with 226 Wp/unit savings on roof maintenance since their new roof has a 30-year warranty renovation.
The glass is made of crystalline silicon, measures 1,700x1,000 mm. The total area of the installation is exactly 938 m2 (10,096 sqFt) installed in a façade with a total power capacity of 21.4 KWp.
