Photovoltaic System Design 1 Introduction After PV workers unremitting efforts, solar cell production technology constantly improve, and increasingly widely used in various fields. Posts and telecommunications in particular, the telecommunications industry in recent years because of the rapid development of communication power requirements have become more sophisticated, so stable and reliable power Solar energy is widely used in communications. And how the various regions of solar radiation conditions, to the design of both economic and reliable photovoltaic power system, which is one of the many experts and scholars study the long-standing issue, but there are many excellent research results, for the development of Chinas photovoltaic laid a solid foundation. The author of the study at the design methodology of experts found that the design has only considered the self-maintenance of battery time (that is, the longest consecutive rainy days), without taking into account the loss of electric batteries as soon as possible after the recovery time (ie, two sets of the longest continuous rain days, the shortest interval between the days). This problem particularly in the southern China region should pay great attention to the southern region because of our rainy day is long too, and for the convenience of independent photovoltaic power system, because there is no other emergency backup power protection, so this problem should be included in the design considered together. In this paper, an integrated design method of the previous advantages, combined with the author over the years actually engaged in the design of photovoltaic power systems experience, the introduction of two sets of the longest consecutive rainy days, the shortest interval between the number of days as the basis for the design of one, and comprehensive consideration of the the impact of solar radiation conditions of the factors that made solar cells, the formula for calculating battery capacity,
