IEA SHC Task 51: Urban Planners Know Little about Solar Energy Potential

Submitted by Baerbel Epp on November 3, 2015
IEA SHC Task 51During IEA SHC Task 51, Solar Energy in Urban Planning, the project partners evaluated the legal, process and education issues of solar in urban planning across the twelve member countries. What they found was: Planners and architects know little about the opportunities of solar energy usage. Solar energy in urban planning is also rarely a topic during university courses for architects or urban planners. The photo shows participants of the latest Task 51 meeting visiting a big PV installation. The meeting was held on the French island of Réunion from 28 September to 2 October. The task is about all types of solar energy.

Portuguese 2020 target for solar thermal: Faraway, so close to deadline

Submitted by Baerbel Epp on October 14, 2015
SotecnisolIt’s just like in the Wim Wenders movie: Each year, the Portuguese goal for solar thermal energy seems more faraway, so close to the deadline. The country, which aims at a target of 2,214,282 million m² of installed area in 2020, saw a mere 1,080,317 m² set up until the end of 2014. In 2014, only 54,961 m² were added, 4 % less than in the previous year. This year, market stakeholders expect stagnation, although figures for the first six months pointed downward. An area of 21,852 m² was newly installed during the first half of 2015, which is a decrease of 18 % compared to the same period last year.

Solar Electric and Solar Thermal Energy: A Summary of Current Technologies (2014)

Submitted by Francesco Gattiglio on June 26, 2015

This document, written by Tayyebatossadat P. Aghaei of the Global Energy Network Institute (GENI), illustrates the different applications of solar thermal and photovoltaic technology. 

After a brief introduction on the history of solar energy, the document firstly explains the functioning of large scale solar thermal technology systems, differentiating between flat-plate collectors and concentrator collectors. This section includes also graphic representations of the different systems.

Resource/Cost Estimates For Solar Thermal Space/Water Heating (2010-2020)

Submitted by Raquel Ponte Costa on June 25, 2015

The Solar heat resource is dependent in the first instance on the insolation falling on the surface of Ireland. The usable power generated by solar panels will vary depending on latitude, time of year and weather conditions. According to the European Solar Thermal Industry Federation, current technology produces per square metre of solar panel between 300 and 450 thermal kWh/year.  The resource area is based on the roof area of existing and future dwellings.

How To – Solar Hot Water (2008)

Submitted by Raquel Ponte Costa on June 21, 2015

This is a how-to instructional guide on how to make your own solar thermal hot water heating system. It was created by the website GreenPowerScience.com. The guide explains how to devise a soalr thermal hot water heating system using a black rubber hose and a heat exchanger. The step by step walks the user through how to build and install the system and the various options they have in doing so.

A Direct Solar Water Heating System for the Health Clinic in the Town of Santa Isabel Cholula, State of Puebla, Mexico (2012)

Submitted by Raquel Ponte Costa on June 21, 2015

This report was written by researchers from Appalachian State University in North Carolina and Universidad de las Americas Puebla in Mexico. It reports on a solar thermal water heating installation for a health clinic in Mexico that was installed by the two universities.

Central Electric Power Cooperative, Inc.: Solar Water Heating Study (2012)

Submitted by Raquel Ponte Costa on June 21, 2015

This study reports on the results of monitoring done to a sample of 70 solar thermal water heating systems installed across four cooperatives. Data loggers were installed in 30 of the solar water heating system homes, to monitor both the solar system and the energy usage of the conventional water heating systems. The systems had been installed with grants administered by the state of South Carolina. The final results of the study were positive. Solar thermal water heating homes were able to use solar heated water in the later afternoon and evening.

Solar Water Heater Project: Design for Sustainable Communities (2009)

Submitted by Raquel Ponte Costa on June 21, 2015

This report was written by Professor Ashok Gadgil of the Environmental Energy Technologies Division at the University of California. The professor and a team of student researchers set out to design a solar thermal water heating system for use by native populations in Guatemala, and the document reports on their success.

Solar Water Heater (2010)

Submitted by Raquel Ponte Costa on June 21, 2015

This report was written by Jean Cariou of the Global Energy Network Institute. It is a comprehensive study of the technology, the economics, and the feasibility of large scale solar thermal installations. According to the report, solar thermal water heating has the potential to reduce electricity use and subsequent energy costs by up to 75% annually.
