• South Africa: Solar Water Heating Strategy & Implementation Plan -

  Last November, South Africa's Department of Minerals and Energy (DME) published the draft of an “Overall Recommended Strategic Framework”. The framework is to come into effect in April 2010. This strategy should help to equip 1 million households with solar water heaters by 2014.

• Mauritius: Rebate Programme Drives the Market-

  The new subsidy programme of the government of Mauritius has been a successful one. More than 4,000 solar water heaters have received a subsidy of 10,000 Mauritius Rupee (MUR), approximately € 279, by the Development Bank of Mauritius (DBM) since August 2008. The target for the first year of the programme is to install around 20,000 systems in households.

  “Now, the solar water heating market is booming,” Raj Appalaswamy, sales coordinator of Kaylor Rotomoulders, a manufacturer of solar water heaters, affirms.

• Chile: Tax Rebate for Construction Companies-

  Sunny Chile: On 19 November 2009, the National Energy Commission held a presentation on the “regulatory framework for solar thermal in Chile” that led to the introduction of a new tax rebate programme for solar water heaters (SWH) in August this year and will last until 2013.

• PROMASOL: Democratizing Access to Solar Water-Heaters (2011)-

  This is a case study prepared by the UNDP in the framework of the project PROMASOL, a UN-funded initiative aimed at developing the Moroccan solar water heating market.

• Design Process and Construction of a Solar Water Heater Operating by Thermosiphon (2006)-

  This article, written by engineers from the Universidad Tecnologica de Pereira in Colombia, presents the design process and construction of a solar water heating collector for domestic consumption, operating by thermosiphon. The processes explained in this article are based on the Colombian technical standards NTC 4368 and the NTC 2461. The article details the mathematical design, selection of materials and process construction.

• Yemen: Framework to Promote Domestic Solar Water Heaters (2009)-

  This presentation was made during the Regional Workshop on SWH Certification and Standardization organised by RCREEE (Regional Center for Renewable Energy and Energy Efficiency) in Tunisia in autumn 2009. The presentation shows the results of a study on the framework needed for the introduction of domestic solar water heaters in Yemen.

• India: Efficiency Labelling for Solar Water Heaters under Discussion-

  The Indian government is thinking about the implementation of a kind of “star label” for solar water heaters. The institution responsible for the national Standards & Labelling Programme scheme is the Bureau of Energy Efficiency (BEE). The national solar industry, however, has some reservations about this plan.

• China: Rebate Programme Increases Market Transparency-

  The result of the first bidding in the spring of 2009: 92 Chinese solar thermal system suppliers, offering a total of 806 products, qualified for the rural incentive programme. The figure shows the number of systems per price range in RMB (10 RMB is about 1 EUR).

• Solar Hot Water and Building and Plumbing Codes – Canada (2005)-

  This page explains revisions that the CanSIA requested in the National Plumbing Code (NPC) regarding solar hot water heaters in Canada. You can find the actual request letter from the CanSIA here

  Among the problems in the National Codes are mis-referencing in certain sections, and clarification of code for custom built solar units.

• Solar Energy in Canada-

  The Canadian Solar Industries Association (CanSIA) produced this bulletin to explain feasible applications for solar energy in Canada. It talks about how cost-effective solar water heaters can be after installation in residential and commercial applications. It also mentions the benefits of the operating costs for solar compared to oil heating systems, as well as residential solar pool heaters that are used seasonally.

• Economic Analysis of Solar Water Heaters in GuangZhou (2006)-

  As a mature applied technology, the largest obstacle to the promotion of the solar water heater is the high initial investment that makes an impact on consumers’ choices.

  The initial investment and maintenance cost of the solar water heater, gas water heater and electrical water heater in Guangzhou was compared and the Annual Cost Calculation Method (ACCM) was used to explain the remarkable economic benefits of solar water heaters.

• Namibia: Solar Water Heaters at Educational Institutions-

• International Experiences with the Promotion of Solar Water Heaters (SWH) at Household-level-

  The objective of this paper is to analyse and evaluate international experiences with the promotion of solar water heaters at household level.

  During the compilation of this study, it became apparent that responsible organisations did not pay much attention to a distinct monitoring and an explicit evaluation of promotion programmes. The study shows which promotion measures resulted particularly successful, which difficulties occurred during their implementation and how these circumstances possibly could have been avoided.

• Use of Renewable Energy in Buildings: Experiences with Solar Thermal Utilization (2006)-

  This 2006 paper gives an overview of the possibilities of solar thermal applications in buildings in China. The paper looks into the current state of solar thermal applications: solar water collectors, floor radiation heating and air conditioning systems. It also touches upon the design aspects and practicalities of integrating solar systems in both residential and public buildings.

  The paper concludes by underlining the expected growth in importance of integrating solar thermal schemes in buildings.
