Large Solar Thermal Systems: Development and Perspectives (2008)

Submitted by Raquel Ponte Costa on February 23, 2010

Currently there are around 120 large scale solar heating plants with more than 500 m2 of solar collectors in operation in Europe, 10 of which are located in Denmark.

The first Danish plant was built in 1987 with 1,000 m2 of ground mounted collectors. Today it still remains active, producing heating for the citizens. The Danish government has set very high targets for district heating in the upcoming years. In the “Strategy for solar thermal”, the Danish Energy Agency has set an ambitious target of 10% of district heating load to be covered by solar thermal in 2030.

Code of Practice for Manufacture and Installation of Solar Water Heating Systems in New Zealand (2004)

Submitted by Raquel Ponte Costa on February 10, 2010

This Code of Practice was published by the New Zealand Solar Industries Association (SIA) to provide guidance to manufacturers, suppliers, and purchasers of solar hot water systems on manufacturing and installation standards to be observed in New Zealand, especially for household installations.

Overall System Performance Modeling: Solar thermal Cooling/Heating of the IW (2006)

Submitted by Raquel Ponte Costa on February 8, 2010

The Advanced Building Systems Integration Consortium (ABSIC) is an industry-university partnership aimed at researching on possibilities to improve building and systems' efficiency.

This presentation goes through a specific project with a twofold objective: design a more efficient solar thermal system and improve the efficiency of existing systems, based on a given building heating and cooling demands.

Results showed that the performance of the systems can be improved up to 27% in winter (around 3MWh) and 49.2% in summer (around 7MWh).

 

Denmark: Delivering Solar Heat at a fixed price

Submitted by Baerbel Epp on January 30, 2010

The newly founded Danish company of Nordic Clean Energy (NCE) offers operators of district and local community heating grids all over Europe a feed-in of solar heat from large collector plants at fixed prices.

Eskom Solar Water Heating Rebate Programme: Claim Process Guide (2008)

Submitted by Raquel Ponte Costa on January 18, 2010

This guide was made to help consumers applying for a Eskom Solar Water Heating Rebate Programme. This rebate programme was set-up by the South African Government to increase the share of renewable energies on the final energy consumption to 10 000 gigawatt hours by 2013.

The guide includes a series of steps that should be taken into account applying for the Eskom rebate scheme, the documents necessary for the application, the systems that are qualified for the rebate and other practical information.

Benefits of Electric Generation Displacement Using Solar Thermal Water Heaters (2005)

Submitted by Raquel Ponte Costa on January 6, 2010

This master thesis, presented at the University of Puerto Rico, explores the benefits of solar thermal water heaters installations. Research has proven that this technology contributes to a demand reduction and reduced power losses at the transmission and distribution levels, which results in reduced costs for both utility and residential customers. Thus, the increased system’s efficiency contributes to a considerable reduction in fuel and energy cost.

Heating Water with Solar Energy Costs Less at the Phoenix Federal Correctional Institution (2004)

Submitted by Hans Craen on December 30, 2009

This report was released by the Energy Efficiency and Renewable Energy section of the U.S. Department of Energy in 2004. It highlights a large-scale solar thermal system installed at the Phoenix Federal Correctional Institution (FCI) and breaks down the statistical output.

The system was financed through an Energy Savings Performance Contract (ESPC), which include an average annual savings of $6,700. The system produces up to 50,000 gallons of hot water daily, 1,000 megawatt-hours of electricity and releases approximately 600 tons of CO2.

Solar Water Heating Legislation in Mexico (2009)

Submitted by Raquel Ponte Costa on December 16, 2009

Jaime Brash G., from the Mexican National Commission for Energy Efficiency (CONUEE), made this presentation during a solar heating and cooling workshop which took place in July 2009 in Mexico City.

The presentation explains the national programme PROCALSOL (2007-2012) created to boost solar energy in the Mexican residential sector. It refers the main obstacles and drivers of the solar thermal development and the new regulations brought by the programme.

Estimations are that by 2012, 1.800.000 m2 of solar collectors will be in place.

REFUND+ Final Report (2009)

Submitted by Raquel Ponte Costa on November 23, 2009

The REFUND + project (2006-2009), supported by the Intelligent Energy Europe and ADEME (Agence de l'environnement et de la maîtrise de l'énergie), intends to identify, monitor and evaluate the impact of incentive schemes on the development of RES heating systems in private households in five countries: Austria, Belgium, France, Italy and Portugal. Implementation of specific financial instruments was simulated in two case studies in Lithuania and Poland.

Solar Thermal Energy Scope in Chile (2009)

Submitted by Raquel Ponte Costa on November 16, 2009

Rubén Muñoz Bustos, from the Chilean National Energy Commission, prepared this presentation for a training workshop on solar heating and cooling, which took place in July 2009 in Santiago, Chile.

The training workshop, organized by different local entities in co-operation with the Spanish Association ASIT and the Spanish Institute IDEA, was addressed mainly to technical staff from public governmental bodies and focused on boosting the use of solar thermal applications in the country.
