石渠县地处康藏高原,位于北纬32°59′,东经98°06′,海拔4200米,气候严寒。县局担负着成都至西宁的省间电话通信和石渠至康定的通信任务,其通信设备最大耗电电流2A。由于无市电,自机务站建立以来,全靠柴汕机供电,年耗柴油9.8吨,加上油料的运输费,造成生产成本较高。但石渠地区大气透明度好,年日照都在2500小时左右,对应用太阳能电池电源解决一个县局的生产用电创造了极为有利的条件,加之近年来,我国硅太阳能电池的成本不断下降,其组件的封装工艺也不断提高,大大的降低了一次性投资的费用和延长了硅太阳能电池的使用寿命。鉴于以上情况并考虑到其技术和经济效益都是可观的,因此于83年 Shiqu County is located in the Tibetan Plateau, located at latitude 32 ° 59 ’north, longitude 98 ° 06’, 4200 meters above sea level, the climate is cold. County Bureau is responsible for Chengdu to Xining telephone communications and Shiqu to Kangding communications tasks, the maximum current consumption of communications equipment 2A. Since no electricity, since the station was established, thanks to Chaishan power supply, the annual consumption of 9.8 tons of diesel fuel, coupled with fuel transportation costs, resulting in higher production costs. However, the atmospheric permeability of Shiqu area is good, and the annual sunshine is about 2,500 hours. This will create extremely favorable conditions for the application of solar cell power to solve the electricity consumption of a county bureau. In addition, the cost of silicon solar cells in China has been declining in recent years. Component packaging technology has also been continuously improved, greatly reducing the cost of one-time investment and extending the life of silicon solar cells. In view of the above and taking into account the technical and economic benefits are considerable, so in 83 years
