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.

Financing Solar Energy in Costa Rica: Case Studies (2011)

Submitted by Raquel Ponte Costa on April 6, 2015

This document provides information on the Costa Rican Institute for Electricity’s (ICE) efforts to bring modern energy resources to the, largely rural, 2% of the Costa Rican population whom live off the grid. An essential component of these efforts involved brining solar thermal technology to indigenous communities.

Solar Water Heating Innovation in the US (2012)

Submitted by Raquel Ponte Costa on April 6, 2015

This document provides an overview of the history of innovation in solar thermal technology and its impact on the market for solar thermal energy. It was created and published by the University of Wisconsin.

Resolution E-4188 (2008)

Submitted by Raquel Ponte Costa on April 6, 2015

This document from the Public Utilities Commission of the State of California is an approval of a renewable portfolio standard power purchase agreement with Gaskell SunTower, LLC (Gaskell), owned by eSolar.  This contract complies with the Renewable Portfolio Standard (RPS) procurement guidelines.  Gaskell SunTower, (LLC) is a new solar thermal generating facility being developed by eSolar.

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).  

Applying UNEP’s Solar Water Heating TechScope Market Readiness Assessment in Mauritius and Seychelles

Submitted by Amr Hai on March 20, 2015

Islands face particular energy challenges. Costly imports of fossil fuels, for one, can burden island budgets and inhibit investment in socio-economic development. SWH systems are highly cost effective in an island setting with high electricity prices. Further attempts to increase SWH uptake in islands will need to address the lack of information on system options and how to install them, upfront financing cost, and difficulty in obtaining loans.

Development of a Solar Rating and Certification Laboratory in Minnesota (2009)

Submitted by Raquel Ponte Costa on March 19, 2015

This is a report prepared by the Minnesota Department of Commerce Office of Energy Security (OES) to the Legislature. It focuses on solar thermal technologies for domestic hot water and space heating. This legislation came about from concerns that the nationally recognized solar thermal certification organization, Solar Rating and Certification Corporation (SRCC), process was inadequately serving Minnesota’s solar thermal industry.

Arizona Solar Energy and Economics Outlook (2009)

Submitted by Raquel Ponte Costa on March 14, 2015

This report was arranged by William P. Patton, Ph. D., Economic and Business Research Center, University of Arizona. The document discusses the need for the United States to make the switch from fossil fuels to solar energy as a more reliable and environmentally sound energy source.A study was conducted in Arizona in order to discover the potential for solar electric generation in Arizona and also to figure out the economic and environmental impacts on the increased use of solar power.

Experiences with the Renewable Heat Law (EWärmeG) Baden-Württemberg (2015)

Submitted by Francesco Gattiglio on March 6, 2015

This presentation, prepared by Dr. Volker Kienzlen of Climate and Energy Agency of Baden-Wurttenberg (KEA), was presented at the EU Conference "Heating and Cooling in teh European Energy Transition", held in Brussels on 26-27 February 2015. 

South Africa: Building Regulation Not Applied as Intended

Submitted by Baerbel Epp on February 1, 2015
SOLTRAIN stakeholder meetingExtended South African National Standard SANS10400 XA, Energy Usage in Buildings, is the big hope of the country’s solar thermal system suppliers. Part XA 2, which was added to SANS 10400 in September 2011, reads: "A minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels.” The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority (for more details, see the attached architectural guide). After a transition period and a broad discussion among those affected by the new regulation, XA officially became law on 9 September 2014. The photo shows one of the stakeholder meetings within SOLTRAIN, the Southern African Solar Thermal Training and Demonstration Initiative.
