Parametric Analysis of Investment Tax-Credit Programs for Solar Industrial-Process-Heat Equipment. Final Report

摘要

The results of a parametric analysis of investment tax credits for solar industrial process heat systems are presented. An investment decision model was used to determine when firms could be expected to invest in solar IPH systems based on given assumptions and an investment tax credit ranging from 30% to 60%. The impacts of the different tax credit levels were then aggregated over industries and solar regions. A 30% tax credit was found to be insufficient to yield significant conversion from conventional to solar IPH. At least 40% was found necessary to make solar competitive with oil in most solar regions, and 50% to make solar competitive with gas. (ERA citation 08:038609)
