| New solar power system at Lake Hennessey Pump Station  The City of Napa dedicated a new solar power system at its Lake Hennessey Pump Station. The 356kW solar power system was designed and deployed by PowerLight Corporation. At over a third of a megawatt, this solar power system is one of the largest municipal solar power systems in Northern California. The City of Napa commissioned a solar power tracking system, PowerLight PowerTracker, to meet a portion of its electricity needs in a clean, sustainable manner. It makes use of an underutilized asset -the grounds adjacent to the pump station- to generate electricity that is clean, silent, and emissions-free.The PowerTracker solar power system features an innovative single-axis design enabling solar panels to follow the path of the sun automatically throughout the day to maximize the panels' energy generation. Napa's solar power generation spares the environment from tons of harmful emissions, such as nitrogen oxides, sulfur dioxide, and carbon dioxide, which are major contributors to smog, acid rain, and global warming. Over the expected 30-year lifetime of the system, the combined solar-generated electricity will reduce emissions of carbon dioxide by 4,200 tons. These emissions reductions are the equivalent to planting 1,170 acres of trees, removing almost 855 cars, or not driving 10.5 million miles on California's roadways. write your comments about the article :: © 2006 Construction News :: home page |
