随着护林防火网化建设的发展,在林区的防火瞭望台,外站,为解决用电困难,继使用过风力发电之后,有的又想到了用太阳能电池。但又有所犹豫不决。怕的是太阳能电池瓦数选得过高,投资过大、选得过低,使得与其相连结的蓄电池易于过放电,影响其使用寿命。如何根据用电的需要以及经济上的可能性恰到好处地选用太阳能电池组及其配套的蓄电池?现介绍如下。用太阳能电池组所依据的四个量:电压,电流、电功率以及蓄电池的容量——安培小时(简称“安时”)。从充电蓄电的观点来看:一、电压(伏):一定的电 With the development of forest fire network construction, in the forest fire observation station, the station, in order to solve the electricity difficulties, following the use of wind power, and some thought of the use of solar cells. But hesitated. Afraid of the solar cell wattage election is too high, the investment is too large, the election is too low, making it connected with the battery is prone to over-discharge, affecting its service life. How to choose the right solar cell and its supporting battery according to the need of electricity and the economic possibility? The introduction is as follows. With the four solar cells based on the amount: voltage, current, electric power and battery capacity - amps (referred to as “An hour”). From the point of view of charging power storage: First, the voltage (volts): a certain electricity
