Metal roof photovoltaic system for energy-saving California winery add luster

Rodney Strong Vineyards in California, Sonoma County, and the vineyards of the output of juice (this word pun, both the "juice" in Italian, can be interpreted as "electric energy", translated as suggested here: " essence ") is not derived from some vines, but thanks to the sun nurtured here.
California sunlight gave birth to high-quality grapes, the vineyards of wine brought honor to Strong, but visitors might not notice, it is these sun also for road lighting and winery facilities provide a large number of refrigeration systems energy.
In the winery warehouse roof metal plate installed on the 766 080-watt crystalline photovoltaic (hereinafter referred to as pv) power generation system is expected to provide 30% of the electricity needs of the vineyards.
The system consists of California Berkeley's PowerLight Corporation installed, containing 4032 pv modules, covering 100,000 square feet winery half of the roof. Each module produces 190 watts power. PowerLight Corporation is the largest construction of a straight seam metal roofing in a gentle slope on the pv projects.
In April last year to start planning the system, from the initial cost, government discounts, generating capacity, return on investment projections to the construction of logistics in all aspects of the study. In September, the winery and PowerLight Corporation reached a consensus and signed a contract. In the next eight weeks to complete the project design, pouring a concrete pad is good, and solar modules shipped to the construction site. All materials are available, it only took less than five weeks, the entire system is installed in place.
General interest in the construction of such a problem, that does not destroy the material and the roof closed at the same time, how to pv module installed standing seam metal roof. Called S-5-U's new fixed-roof technology provides a solution for this. The technology of the fixture by the Colorado Springs, Colorado, the company customized according to customer needs. Although the installation has more than 10,000 single fixed point, but this fixture in its annex (Round brake bolt) under the coordination of the Galvalume steel roof has a hole on the need.
The pv with standing seam stone coated metal roof system that combines the concept is increasingly widely accepted, and this concept has been a reasonable explanation. Roof plate film pv systems often need to be replaced before the end of life, and standing seam roof is precisely to overcome this shortcoming, and crystal module because it has the same life.
In addition due to the high reflective metal roof, this roof system installed pv ultimately proved to be a cooling effect of the roof. Pv module installed in the roof a few feet away from high places, so that the metal roofing  is in its shadow, while between the formation of an air ventilation system. U.S. Department of Energy Oak Ridge National Laboratory study shows that, due to shadowing effects and the ventilation system air flow, the temperature of the roof can be reduced 65F, so as to reduce the burden of cooling the building.
The combination of metal roofing and pv system can make the roof of the net weight per square foot less than 3.5 pounds, the support structure and thereby reducing the cost of board design.
Despite Strong winery pv system cost $ 4.3 million, but the California public utility commissions to provide $ 2.1 million as an incentive, so Strong winery only take $ 2.2 million. In the government's tax incentives, the costs will be easier to accept. So whether from environmental or economic point of view from California wineries such new energy are reasonable.

Legend: Installation in California's Rodney Strong Vineyards Sonoma County on the roof of the more than 4,000 solar panels, give the vineyard to provide 30 percent of its electricity needs. Thus brought about shadows and forced ventilation can reduce the roof temperature 56F, thereby reducing the internal cooling load (above). Each board has four fixed points, with the S-5-U clamp (see insert map) they are fixed in the seam metal roof on the stand, so you do not have a hole in the roof.
