Photovoltaic system in northern climes to 5.61 kWh/m²/day in the sunniest regions. For large systems, the energy gained by using tracking systems can outweigh the added complexity (trackers can increase efficiency by 30% or more). For very large systems, the added maintenance of tracking is a substantial detriment. Tracking is not required for flat panel and low-concentration photovoltaic systems. For high-concentration photovoltaic systems, dual axis tracking is a necessity. Pricing trends affect the balance between adding more stationary solar panels versus having fewer panels that track. When solar panel prices drop, trackers become a less attractive option. Systems designed to deliver alternating
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
