Beginning in 2008, 5 percent of Black Hills' generation must come from renewable energy resources. Of that amount, 4 percent must come from solar resources, and half of the solar resources must come from solar technologies located on-site at customer facilities. PV technology is very reliable and has been available for many years. Their incentive program is designed to encourage greater use of solar power by reducing the costs of residential and commercial PV systems. For more information visit their website>>
