Rodney Strong Vineyard is a family-owned business, founded in 1959. In effort to cut energy costs and be environmentally responsible, Jim Magnus, facilities manager for the winery, began researching and ultimately chose photovoltaic energy as a source of sustainable energy. He chose PowerLight to manage the project, stating that, “There are a lot of outfits jumping into this PV business. We didn’t want to be a teething ring for some newcomer to the industry.”
Careful planning sped up the installation process. The vineyard already possessed a perfect mounting platform for the array - standing seam metal roofs which capped the existing barrel aging rooms. A chief concern was how the PV modules could be attached to the standing seam metal roofs without jeopardizing material and weather-tightness warranties. The answer was found with S-5! attachment technology for standing seam metal roofing.
The design of the attachment clamp and attendant round-point setscrews enabled the entire installation to occur without a single penetration through the steel roof’s surface, even though there were more than 10,000 individual attachment points. One huge environmental perk is that the combination of PV installation over standing seam roofing may prove to be the ultimate cool roof, saving Rodney Strong Vineyards significant cooling costs in the summer. Having PV modules raised several inches above the surface of a roof casts the metal roof panel in shade and creates an air plenum. This reduces rooftop temperatures by as much as 65°F, reducing the building’s cooling load.
After the power conversion from DC to AC power has taken place, the array provides about 680,000 watts of AC power - about 30% of the vineyard’s power requirements. The excess energy the system creates is being fed back into the utility grid and sold to the local utility, avoiding still more burning of fossil fuels and helping with system payback to Rodney Strong. At peak output, the generation system will produce enough electricity to power about 800 single-family homes, and will keep enough carbon dioxide out of the environment during the next 30 years to equal the removal of 59 cars from the roadways each year.
The S-5-U clamp ("U" is for Universal") accommodates most standing seam profiles in North and South America. The clamp offers multiple hole orientations for both horizontally and vertically-oriented double-folded seams.
