Photovoltaic system and is typically less useful than a calculation of return on investment. While it is typically calculated to be between 10 and 20 years, the financial payback period can be far shorter with incentives. Due to the low voltage of an individual solar cell (typically ca. 0.5V), several cells are wired "(also see copper used in PV systems)" in series in the manufacture of a "laminate". The laminate is assembled into a protective weatherproof enclosure, thus making a photovoltaic module or solar panel. Modules may then be strung together into a photovoltaic array. In 2012, solar panels available for consumers
Alamosa photovoltaic power plant in comparison to the amount of power generated. Alamosa photovoltaic power plant Alamosa photovoltaic power plant, is an 8.22 MWp photovoltaic power plant located in San Luis Valley, Colorado, USA. The power plant was developed by SunEdison, sells all output to Xcel Energy, and was completed in December 2007. The plant occupies of land, and provided enough power to supply 1400 homes in 2008. This made it the largest producer of photovoltaic power in the United States in 2008. Colorado Xcel customers pay approximately 2% more for electricity to subsidize renewable energy projects. The plant has received some criticism, saying
