|Title:||Building Integrated Photovoltaic Power Systems Guidelines for Economic Evaluation|
|Description:||The objective of the Guidelines for the Economic Assessment of Building Integrated Photovoltaic Power Systems is to identify the economic parameters of BIPV systems. The guidelines are structured in three major parts: the investment analysis itself (i.e. methods and ownership issues), the benefits and the costs of BIPV systems. Also, a short comment is paid to measurement and verification. The (brief) outline and evaluation of the various general methods to analyze investment showed their effectiveness for BIPV systems. Naturally, all investment methods can be used to evaluate the BIPV economics (in relation to other techniques). However, for the purpose of designing and sizing BIPV systems, either the net present value method or the life-cycle cost method is recommended as BIPV has the tendency to have increased net benefits and/or leads to reduced (future) life cycle costs. The criteria for the cost-effectiveness are subjective depending on the investment decision-maker. The most likely investor / decision-maker is the long-term owner-occupant as he / she is best positioned to reap benefits from BIPV systems, as these are capital-intensive and have low operating costs. The benefits of BIPV cover a broad range of aspects, as there are: multiple (building) functions, electricity benefits, grid-support benefits, control of load growth by utilities (institutionalized by utility and national incentives & programs), demand savings, power quality and reliability, promotional & educational benefits, environmental benefits, shading and thermal benefits, security. Each of these topics are addressed, if possible with (international) examples. The costs of BIPV depend on the system technology, utility interconnection costs, labor & installation costs, associated costs for building permits, maintenance costs, costs for replacement & repair and the salvage costs (or value). Each of these topics are addressed, if possible with (international) examples. As the international market BIPV is divers, rapidly developing and market by various market segments, no general quantitative data could be presented of the cost and benefits of BIPV. However, this report reflects an extensive list of valuable data addressing all possible economic factors, relevant for an economic analysis. As incorporated in the title, the report can be used as a guideline to perform an economic analysis of BIPV systems.|
