光伏气象数据来源分析

Meteo data comparaison

本文列举了市场上的主流气象数据软件及数据源（），比较分析了气象数据源的差异及优先应用地区，对于光伏系统设计仿真，发电量的预测具有很好的实际指导意义，供各位光伏同行讨论学习。


Global comparison between all sources: the figure shows a comparison between all available sources, for 12 locations in Europe. All values are by respect to the Meteonorm values (PVsyst internal default).
Except the first green bin, which shows the difference of Meteonorm by respect to the average of all other sources (excluding Helioclim 2005).
We can observe some trends:
        We cannot say which source is the more representative of the reality  (and which reality? - no one is of course able to foresee the future climate).
        Meteonorm often gives lower values than the average. This means that simulations with default values in PVsyst will be rather conservative, and give prudent results for the final yield of the customer’s systems.
        Except at Barcelona, very little differences between Meteonorm “old” (1961-1990) and “new” (1981-2000) data.
        PVGIS seems to be one of the more compatible with Meteonorm data.
        Also, when available, the WRDC data are well representative of the Meteonorm data.
        Satellight data seem to overestimate the average by 5 to 10% (except in Berlin and Roma).
        The Helioclim data response seems to be chaotic. Especially the 2005 values (Helioclim-2 hourly file) are very high over the other data, by a factor which is not compatible with the 2005 irradiance (see below for Geneva).

楼主能给Meteonorm最新版的么！我现在用的才是5.1版的，谢谢了邮箱

Meteonorn 6.0软件和破解可以在论坛下载，地址如下：

这个是Meteonorn网站介绍气象数据分析嘛

没错啊，也没说是原创嘛。
这么专业的东西，不是一般人能总结出来的，呵呵。

只是发出来大家讨论，因现在光伏项目业主越来越看重后期发电量的保证了，甚至还会要求建设承包商做出担保，所以不能盲目的选择乐观的气象数据，要具体分析，选择比较符合当地实际的气象数据，这样才能模拟计算出贴近实际的发电量，降低风险！

采用当地气象站多年平均数据最准确

很多地方都没有测量仪器的

这也得当地有这些数据啊

冰山一角

当地气象站的数据是要怎么获取啊

NASA参考参考，但是我也不知道用什么更见准确

NASA的数据哪里找？
