Mexico: Ongoing Struggle over Legally Binding Standards

Submitted by Baerbel Epp on August 24, 2016
CONUEEDespite being the most robust solar thermal market across North and South America in terms of growth (8 % YoY in 2015), Mexico is still struggling domestically to harmonise its quality standards for solar thermal heaters. The lack of understanding between local producers and equipment importers has been the main hurdle to legally binding and uniform rules. However, the process is ongoing and the market’s stakeholders expect a draft of the official NOM-027-ENER-2015 to be available for public consultation by the end of 2016.

Quality Infrastructure Crucial to Emerging Markets

Submitted by Baerbel Epp on January 11, 2016
IRENA 2In December 2015, the International Renewable Energy Agency (IRENA) published a comprehensive report on how to establish a quality infrastructure (QI) for solar water heaters on small-scale markets (see the attached document). The 76-page study is part of a series on Quality Infrastructure for Renewable Energy, which uses information from 83 survey respondents and data from interviews with 34 experts on QIs for renewable energy sources. The report discusses established international system and collector testing standards as well as examples of implementation across selected countries. It also highlights market barriers and makes recommendations for developing solar water heater Qis, focusing mainly on emerging markets. The programme highlights the complexity of a quality infrastructure, including the establishment of a product label, test labs, installers’ certification and the involvement of inspection bodies.

Uruguay: The Battle for Market Growth Continues

Submitted by Baerbel Epp on September 23, 2015
Uruguay market developmentUruguay, whose population of 3.4 million makes it one of the smallest countries in Latin America, has shown positive market development since 2007. Cumulated installed solar thermal power saw a notable increase from 1 to 9.5 kWth per 1,000 inhabitants. According to numbers published by the National Energy Department and the annual national energy report, the country’s total collector area installed by the end of 2014 amounted to 46,241 m². Mesa Solar, the multi-sector network for the promotion of solar energy in Uruguay calls for accelerated growth to achieve 1 million m² in 2020. The official target of the government is 150,000 m² until 2024.

Latin America on Its Way to Solar Thermal Quality Standards

Submitted by Baerbel Epp on August 31, 2015
Costa Rica WorkshopBrazil is going to implement compulsory certification of solar water heating (SWH) equipment in 2015. Uruguay, Argentina, Chile and Mexico already have laboratories for testing, and Costa Rica has recently set up one. Latin America is working through the regional Pan American Standards Commission, COPANT, on regional standards for SWHs, with the aim of harmonising them with ISO standards. The region is not yet considering a common regional testing and certification scheme, but there is a growing consciousness of the fact that testing and certification performance, as well as quality is very important to developing the SWH markets of the region. It is the reason why 50 experts from 14 countries have recently discussed how to accelerate the process: The Regional Forum (from 29 to 30 June 2015) was jointly organised by the International Renewable Energy Agency (IRENA), the project “Quality Infrastructure for Renewable Energy and Energy Efficiency in Latin America and the Caribbean (LAC)” coordinated by the National Metrology Institute of Germany, PTB, the Latin American Energy Organization, OLADE, the Electricity Institute of Costa Rica, ICE, and the National Standards Body of Costa Rica, INTECO. All presentations are available for download on the IRENA website.

Solar Thermal Heating (2009)

Submitted by Raquel Ponte Costa on June 21, 2015

This brochure was created by CareyGlass Solar. It explains how solar thermal water and air heating function, and the various technologies that make this possible.

The report details how solar thermal collectors are able to capture the heat of the sun and then pump that energy through a home’s air or water heating systems; there is a diagram to demonstrate this process. From here, the brochure explains how to properly fit and select collectors based on a home’s needs, and whether evacuated or flat plate is the proper collector type.

Enhanced and Expanded Solar Thermal Test Capabilities (2011)

Submitted by Raquel Ponte Costa on June 21, 2015

This document focuses on new solar thermal test capabilities used in the certification of solar thermal collectors. The Florida Energy Systems Consortium (FESC) created this document to help explain how their certification systems works and what the benefit will be to the solar thermal market.

Efficiency of Evacuated Tubular Solar Thermal Collector (2011)

Submitted by Raquel Ponte Costa on June 21, 2015

This presentation was created and published by Junkun Ma and Xialu Wei of Southeastern Louisiana University. It provides an overview of how the measure the efficiency of evacuated tubular solar thermal collectors. In particular, the researchers set out how to best determine the efficiency of single ended evacuated tube collectors. Geometric modeling can be used for mounting angles and system analysis can be used for aspect ratios. The system analysis looks at heat transfer, fluid dynamics, volume force; which all are used as inputs in the efficiency function.

Basic Solar Theory and Application for Building Officials (2012)

Submitted by Raquel Ponte Costa on June 20, 2015

This presentation was created by William Lussier of Gateway Community College. It provides information on solar thermal theory, systems, and applications targeted at building officials; including a focus on solar thermal.

2009 Updates and Trends – IREC

Submitted by Raquel Ponte Costa on June 14, 2015

This report was from the Interstate Renewable Energy Council (IREC) Annual Meeting in October, 2009. The report is broken down to cover state incentives & policy trends, solar installation trends, net metering & interconnection updates & trends, and workforce development and training. For current policies that are mentioned to withstand solar growth, they mention the Energy Improvement and Reinvestment Act (part of the federal “bailout bill” in 2008) and the American Recovery and Reinvestment Act (part of the “stimulus bill” in 2009).

Guidebook for Solar Water Heating Projects in Philadelphia (2011)

Submitted by Raquel Ponte Costa on May 31, 2015

This guidebook was created by the US Department of Energy’s Solar America Cities partnership in conjunction with the City of Philadelphia. It explains how solar thermal works, how to size and install, and the permitting and listening system for projects in the city.
