New ECOWAS Solar Thermal Energy Program : Background, Components, Process (2014)

Submitted by Raquel Ponte Costa on February 24, 2015

On 13 June 2014, Hannes Bauer, Solar Thermal Program Manager at ECREEE, ECOWAS Center for Renewable Energy and Energy Efficiency, gave a workshop in Cabo Verde on the new ECOWAS (Economic Community of West African States) Solar Thermal Energy Program. 

The 1st part of the presentation focuses on the global market growth of solar thermal collectors, showing that from 2000 to 2010 the market has increased steadily by 20% each year. It also shows that West African States were not participating during that period. 

India: UNDP Supports 53 New Concentrating Solar Thermal Projects

Submitted by Baerbel Epp on February 23, 2015
UNDP GEF ProjectThe Concentrating Solar Heat (CSH) subsidy scheme in India, managed by the United Nations Development Programme (UNDP), started in April 2012 with the target to install 90 demonstration and replication projects totalling 45,000 m² of collector area until March 2017. After half the project period had been over, the UNDP was able to present satisfactory results: The scheme has already helped implement 59 projects with a surface area of 16,373 m². The pie chart shows the shares of different applications in the overall collector area. The largest share, 59 % (9,614 m²), is made up of demonstration projects in process heat or solar cooling.

Spain: Canary Islands Publish Guide on Hotel Solar Use

Submitted by Baerbel Epp on February 21, 2015
Reference Hotel Canary IslandThe regional government of the Canary Islands has published a guide on increasing the use of solar thermal in the local hotel sector. The government presented and distributed the study TRNSHOTEL, an analysis and proposals to optimise the solar thermal energy consumption in the Canary Islands hotel sector, during public seminars on 26 and 27 November 2014. The study can be a useful means of developing solar water heating technology in a region boasting a huge tourism sector but great untapped solar potential. The figure shows the 146-room hotel which was used as a reference throughout the study and was simulated in TRYNSYS by the Instituto Tecnológico de Canarias (ITC) to analyse building orientation and list the different solar energy yields and cooling loads (see the attached TRNSHOTEL PDF).

Solar Air-Conditioning System Using Single-Double Effect Combined Absorption Chiller (2014)

Submitted by Raquel Ponte Costa on February 19, 2015

This presentation on solar air-conditioning system was given by Kawasaki’s Hajime Yabase, together with Kiyohshi Saito of the Waseda University and Muhammad Idrus Alhamid of the University of Indonesia, at the ATMOsphere conference which took place in Tokyo from 3 to 5 February 2014.  The speakers outlined the numerous advantages of using double-effect absorption chillers in solar air-conditioning system.    Absorption chillers use water as refrigerant instead of Freon, they consume less energy than electric chiller and different energy sources can be used.  The presentation also compares a

Active Solar Systems: ENGS-44 Course on Sustainable Design (2014)

Submitted by Raquel Ponte Costa on February 19, 2015

This presentation on active solar systems was given during a course on sustainable design by Benoit Cushman-Roisin, Professor of Engineering Science and Director of the Master of Engineering Management Degree Program of  Dartmouth College in New Hampshire.

Report on Solar Energy and Heat Pumps (2009)

Submitted by Raquel Ponte Costa on February 19, 2015

The present economical context prevails upon finding new heating technologies, that would generate primary energy saving and supposed to show competitive investment costs.  In this document we tried to present the main offer available today, and also to determine their advantages and draw backs. 

Resource/Cost Estimates for Solar Thermal Space/Water Heating 2010 and 2020 ((2004)

Submitted by Raquel Ponte Costa on February 19, 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. 

Solar Water Heating Systems in Libya (2013)

Submitted by Raquel Ponte Costa on February 18, 2015

This presentation on solar water heating (SWH) systems was given by Dr. Mohamed Erhouma, Head of Solar Thermal Energy Conversion Department at CSERS (Center for Solar Energy Research and Studies) at a workshop on “Promoting Renewable Energy & Energy Efficiency in Libya” organized jointly by  REAOL (the Renewable Energy Authority of Libya) and the World Bank.

Local Employment through the Low-Pressure Solar Water Heater Roll-out in South Africa (2013)

Submitted by Raquel Ponte Costa on February 18, 2015

This study has been conducted by the Energy Research Center of the University of Cape Town and aims at demonstrating how developing low-pressure solar water heaters (LP SWH) can have an impact on reducing poverty and inequality and creating employment possibilities in South Africa.

Brazil: Mandatory Certification Postponed to September 2015

Submitted by Baerbel Epp on February 18, 2015
Certifica SolOriginally, the Brazilian Labelling Program, PBE, was supposed to become mandatory in July 2014. Now, in 2015, the industry is still waiting for the so-called compulsoriedade to become reality. The label has so far only been mandatory for solar water heaters intended for the federal social housing programme Minha Casa Minha Vida (see photo). In January the press department of INMETRO confirmed per email that there was already a new deadline for manufacturers: From September 2015 on, Brazilians may only produce or import collectors and tanks adhering to the technical requirements for quality based on standard ABNT NBR 15747, which is European norm EN 12975-2 adapted to Brazilian climate conditions. INMETRO also confirmed that resellers would still be allowed to buy non-conforming products until March 2016. After that date they could only sell non-conforming products from their own stocks. From March 2017 on, Brazilian developers would no longer be able to buy or install any solar heating system without an INMETRO certificate – assuming that there won’t be any more delays in implementation.
