光伏成本的持续下降趋势以及各种各样的支持措施，使光伏并网系统（PVGCS）在满足某些经济条件时成为有利可图的投资。内部收益率（IRR）对于这些光伏系统的潜在业主来说是一个有意义的参数。然而，这一参数必须通过非分析方法进行估计。本文介绍了一些易于使用的表格，以估计内部收益率，避免繁琐的计算，这是一个有吸引力的功能，业主，营销人员和设计师。首先，目前和近期的成本PVGCS审查，连同一些财政奖励目前可用。这就引入了使用表格的经济情景。对这些系统的经济分析的简短介绍为最终提出用于估计IRR的表格提供了坚实的基础。最后，三个例子说明了表格的使用。
A continuous decrease trend in PV costs together with a wide variety of supporting measures have turned photovoltaic grid-connected systems (PVGCS) into a profitable investment when some economic conditions are met. The internal rate of return (IRR) is a meaningful parameter for prospective owners of these PV systems. Nevertheless, this parameter has to be estimated by means of non-analytical methods. This paper presents some easy-to-use tables addressed to estimate the IRR avoiding cumbersome calculations, which is an attractive feature for owners, marketers and designers. Firstly, current and near-term costs of PVGCS are reviewed, together with some financial incentives available at present. This introduces the economic scenario, where the tables are to be used. A short introduction to the economic analysis of these systems provides a solid ground to eventually present the tables intended to the estimation of the IRR. Lastly, three examples demonstrate the use of the tables.
