Heliostat Production Evaluation and Cost Analysis

摘要

The primary objective of ths study is to provide a factory cost for the production of heliostats in terms of 1979 dollars. Factory cost is defined as the sum of all direct labor, direct material and burden expenses that are incurred in the manufacture of a heliostat, and its packaging for shipment. Transportation, installation, taxes other than plant real taxes, profit, selling expenses, and all other profit and loss items are not included. Two production volumes are considered, 25,000 heliostat units per year and 250,000 heliostat units per year. The study concluded that the factory cost to manufacture heliostats is $95.99/m exp 2 at 25,000 units per year and $67.95/m exp 2 at 250,000 units per year. The Policy Analysis Branch of the Solar Energy Research Institute estimates that this implies an installed price of $122.12/m exp 2 at the 25,000 unit per year volume. (ERA citation 05:025617)
