Solar Thermal Flat Plate Collectors (2011)

Submitted by Raquel Ponte Costa on May 24, 2015

This technical document was created and published by solar manufacturers Chromagen and State Water Heaters. It is a technical readout of their solar thermal flat plate collectors. The document lists and analyzes many of the key features of their collectors including the single plane glazing, the nylon glass fiber moldings, and the absorber plate. A diagram breaks down and labels the various layers of the collectors, from the glazing to the inner tube configuration. Charts and tables end the document by demonstrating various aspects of the collector’s efficiency.

Wind Issues in Solar Thermal Performance Ratings (2009)

Submitted by Raquel Ponte Costa on May 24, 2015

This report comes from the United States National Renewable Energy Laboratory (NREL), and was written by Jay Burch of NREL and Ross Casey of the University of Colorado. It reports on their research findings on issues with the U.S. Solar Rating and Certification Corporation’s (SRCC) solar thermal performance ratings system. The researchers studied potential biases in SRCC’s testing of glazed and unglazed collectors in regards to how wind is factored into the testing.

Solar Water Heating in Brazil (2006)

Submitted by Raquel Ponte Costa on April 9, 2015

This article was written for “Tiempo”, a newsletter on climate and economic development.  It provides information on solar thermal water heating programs targeted for low-income families in Brazil.

Solar Thermal Energy Technology and Market Trends (2010)

Submitted by Raquel Ponte Costa on April 7, 2015

This presentation was created by Frank Proske, the Market Development Manager for Renewables at A.O. Smith Water Products Co. in Pennsylvania, USA.  The focus of the presentation is on the evolution and current state of various solar thermal technologies and the maturation of their market.

The presentation identifies a few key factors as the driving trends in the solar thermal market.

Utility Solar Water Heating Initiative and Energy Star (2011)

Submitted by Raquel Ponte Costa on April 7, 2015

This letter was written by Chip Bircher of USH2O, a solar thermal water heating industry group, to the Environmental Protection Agency (EPA). It answers questions that the EPA had regarding solar thermal water heating and its eligibility for the Energy Star Program.

USH2O makes the argument that solar thermal water heating should remain eligible for the Energy Star labeling program. Solar thermal sales have shown consistent growth, and so it is important to maintain the relationship as the use of solar thermal becomes more widespread.

SOLARGENIX ENERGY, LLC Proposed Guidelines for Implementing California’s Renewables Portfolio Standard (RPS). (2004)

Submitted by Raquel Ponte Costa on April 6, 2015

Solar thermal generation (with gas assist) has been shown to be cost competitive when compared to other similar fossil technologies providing comparable products, i.e. firm on-peak capacity and energy.  The recently published CEC Cost Comparison Report concluded that, essentially, solar thermal generation with gas assist is cost competitive to combustion turbine technology when used in the same application (firm peaking).  

Switzerland: New Buildings to Reach Nearly Zero Energy Standard by 2020

Submitted by Baerbel Epp on January 24, 2015
Swissolar TrogenOn 9 January 2015, the Swiss Conference of Cantonal Energy Directors agreed on nationwide model rules for building energy codes. These rules include a nearly zero energy standard for new buildings from 2020 onwards and a 10 % renewable requirement for heating system retrofits. Although Switzerland is not a member of the European Union, the country’s energy standards are similar to what the European Energy Performance of Buildings Directive (2010/31/EU) requires from member states.

India: First Vacuum Tube Testing Centre Established

Submitted by Baerbel Epp on December 2, 2014
Pune UniversityThe School of Energy Studies at Savitribai Phule Pune University, located in Maharashtra state, has set up India’s first vacuum tube testing centre. The investment was around INR 4 million (about EUR 50,000) and was funded entirely by the Ministry of New and Renewable Energy (MNRE). “Considering the expertise available at our university – in physics, electronics, as well as chemistry - it was the obvious choice,” Professor Subhash Ghaisas, Director of the School of Energy Studies, said. His institution also has the first testing centre for concentrating solar thermal technology, which was inaugurated in July 2014.

Regional Market Assessment Report in the Mediterranean Countries

Submitted by Raquel Ponte Costa on October 28, 2014

The purpose of this regional market assessment report is to help overcome some relevant barriers which currently prevent solar water heating (SWH) systems from providing a larger share of energy supply in Mediterranean countries, i.e. the lack of knowledge and trust on the technology, as well as the lack of systematic statistics on the solar thermal market and industry, and the very limited return on experiences.
