Specifically for the case of solar energy collectors, job creation is mainly related to the construction and installation of the collectors. The latter is a decentralized process, since it requires the installation of equipment in every building or for every individual consumer.
These technologies use the sun’s energy and its direct and indirect effects on the earth (solar radiation, wind, falling water, and various plants; i.e., biomass), gravitational forces (tides), and the heat of the earth’s core (geothermal) as the resources from which energy is produced.
Solar collectors are the main components of any solar system, so in Chapter 3, after a review of the various types of collectors, the optical and thermal analy- ses of both flat-plate and concentrating collectors are given. The analysis for flat-plate collectors includes both water- and air-type systems, whereas the
The book can also be used as a reference guide to practicing engineers who want to understand how solar systems operate and how to design the systems. Because the book includes a number of solved examples, it can also be used for self-study. The international system of units (SI) is used exclusively in the book.
The present state of solar energy technologies is such that single solar cell efficiencies have reached more than 20%, with concentrating PVs at about 40%, and solar thermal systems provide efficiencies of 40%e60%. Solar PV panels have come down in cost from about $30/W to about $1.4/W in the past 3 decades.
The two primary solar technologies used are central receivers and distributed receivers employing various point and line focus optics to concentrate sunlight. Central receiver systems use fields of heliostats (two-axis tracking mirrors) to focus the sun’s radiant energy onto a single tower-mounted receiver (SERI, 1987).
