Concentrated Solar Power – Focusing the sun’s energy for large-scale power generation (2009)

Submitted by Raquel Ponte Costa on June 15, 2015

This fact sheet was written by the Environmental and Energy Study Institute in 2009. The document starts with a brief background on solar thermal energy and then describes the different types of solar thermal systems (parabolic trough, linear fresnal reflectors, dish/engine, power tower). It covers nighttime generation and how systems use supplemental fuels or thermal storage. The “Water and Land Impacts” section discusses land requirements for single rooftop systems to large power tower systems and water usage.

American Solar Works – Harness Your Energy for Your Business (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This document was prepared by the American Solar Works Holdings LLC. While it gives background information, it primarily tries to encourage solar thermal use for commercial buildings and businesses. Several commercial examples are used of what solar thermal can be used for including: heating hotel domestic hot water, providing showers for athletes and students, washing livestock, providing “green” clean clothes at a laundry mat, heating a building in the winter and augment your absorption chilling in the summer.

Green Institute Issue Brief on Solar Energy (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was issued by the Green Institute in 2008 and discusses the option of a “solar carve-out” to build Minnesota’s solar future. To develop Minnesota’s renewable sources beyond 25 percent, development of additional renewable energy will be necessary, specifically solar technology. A carve-out is an addition to a renewable energy standard (RES) that specifies a portion of the RES needs to be met with a particular technology – solar.

Heating Water with Solar Energy Costs Less at the Phoenix Federal Correctional Institution (2004)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was released by the Energy Efficiency and Renewable Energy section of the U.S. Department of Energy in 2004. It highlights a large-scale solar thermal system installed at the Phoenix Federal Correctional Institution (FCI) and breaks down the statistical output. The system was financed through an Energy Savings Performance Contract (ESPC), which include an average annual savings of $6,700.

Unified Facilities Criteria (UFC) – Solar Heating of Buildings and Domestic Hot Water (2004)

Submitted by Raquel Ponte Costa on June 13, 2015

This handbook was released by the US Department of Defense in 2004. It presents design criteria and cost analysis methods for sizing and justification of solar heat collectors for potable water and space heaters. Sufficient information is presented to enable engineers to design solar space conditioning and water heating systems or conduct feasibility studies based on solar collector performance, site location, and economics. Both retrofit and new installations are considered.

On the Rise – Solar Thermal Power and the Fight Against Global Warming (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was put together by Environment America Research and Policy Center in 2008 and is about how the use of solar thermal technologies can help stop the threat of global warming. Electricity generation accounts for more than a third of America’s emissions of global warming pollution. Using concentrating solar power (CSP) can make a large contribution toward reducing global warming pollution in the United States. This document states the capacity in the States to expand its solar thermal market.

Field Monitoring of Solar Domestic Hot Water Systems Based On Simple Tank Temperature (1995)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was a joint effort from the National Renewable Energy Laboratory, Sacramento Municipal Utility District, prepared for the American Solar Energy Society at the Solar 1995 Conference. This report has equations to use to calculate solar loop gain and tank losses. Analysis is based upon the tank energy balance – identifying solar gain during the day and tank losses at night. These gains and losses can be compared to expectations based upon prior knowledge and estimated weather conditions.

Canada Shines With Solar Expertise (2010)

Submitted by Raquel Ponte Costa on June 13, 2015

This paper was released by Foreign Affairs and International Trade Canada in 2010. The Vancouver Olympic Games showed large-scale success of solar thermal energy in Canada. Solar thermal modules supplied energy that supplied the Vancouver Olympic Village buildings and utilized it for other purposes. Estimates say that the buildings achieved 30 to 70 percent greater energy efficiency compared to standard buildings built to minimum code.

Conceptual Design of a Solar-Thermal Heating System with Seasonal Storage for a Vashon Greenhouse (2006)

Submitted by Raquel Ponte Costa on June 13, 2015

This is a thesis research paper from the University of Washington in 2006. The objective of the study is to design a solar thermal heating system with seasonal storage for a greenhouse, optimized for the environmental impact, thermal efficiency and cost. The main goals of the study is to: provide 100 percent solar heat to the greenhouse; limit the size of the storage to fit within the footprint of the greenhouse; minimize environmental impact and cost; maintain greenhouse temperatures ideal for optimum growing; maintain historic greenhouse structure.

Underground Thermal Energy Storage (2011)

Submitted by Raquel Ponte Costa on May 31, 2015

This presentation comes from the international polymer processing company REHAU. It provides information on their systems for underground thermal energy storage.
