Hess Collection Winery

Winery Solar Electric Installation Project Profile

Committed to environmentally conscious and sustainable business practices, installing solar power was a natural choice for Hess Collection Winery. SolarCraft designed, engineered and installed the 649 kW solar photovoltaic system at its Napa, CA production facility.

Providing nearly 100% of the electrical needs for their operations, the solar power system will reduce their carbon footprint while saving millions in utility costs in the years to come.

As with all solar power systems, the clean, renewable energy from the solar panels will help lessen the load on the grid and offset the emission of greenhouse gases into the atmosphere.

The solar photovoltaic system is roof-mounted, spanning 44,555 square feet. The system consists of 2,200 Hanwha Solar 295-watt solar panels, powering their offices and production facilities with clean, renewable energy.

The system's solar electric panels are expected to generate approximately 945,450 kilowatt hours of energy annually, providing 100% of the winery's annual energy consumption. The new solar energy system enables Hess to generate enough electricity each day to power 148 average homes. It will spare the air nearly 272 tons of harmful greenhouse gases annually. Over the next 30 years, the air pollution saved will be equivalent to eliminating almost 16 million miles of driving.
