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
Shigatse Photovoltaic Power Plant Shigatse Photovoltaic Power Plant The Shigatse Photovoltaic Power Plant () is located 3 km northwest of Shigatse, the second largest city in Tibet, China. It was connected to the grid in July 2011. The plant sits in the industrial photovoltaic area of Shigatse about 3 km northwest of the city in the Xigaze Prefecture, at an altitude of 3895 meters. According to Suntech CEO, “with intense sunlight and cool temperatures, Tibet is extremely well-suited for the utilisation of advanced photovoltaic technology”. Tibet has abundant solar energy with more than 3,000 hours of sunshine annually. Construction was undertaken by the Linuo
