Solar Water Heating Calculator

Submitted by Raquel Ponte Costa on February 17, 2012

The requirement of hot water varies from person to person depending upon his water uses pattern. However, it is estimated that the average hot water requirement per person per day in an average household in India is around 65 liters at 40º C. For calculations of hot water requirement and sizing of solar water heater system, a software was designed in India to help any resident to calculate their Solar Water Heating System needs.

Global Solar Water Heating Market Transformation and Strengthening Initiative (GSWH)

Submitted by Nigel Cotton on February 9, 2012

Generally composed of solar thermal collectors, solar water heaters provide a simple, cost-effective, and sustainable means of heating water for domestic and other uses.  In addition to reducing green house gas emissions, solar water heating (SWH) offers a host of potential benefits to both individuals and governments seeking to reduce their dependence on fossil fuels.  In countries where energy demands are exceeding capacity, SWH can reduce pressure on the national power system and diminish pollution produced by conventional energy sources.  Economic benefits include enhanced employment opportunities and the creation of small- and medium-sized SWH businesses.  The development of such business could, in turn, lead to improved product quality.

While active promotion of SWH in selected countries has resulted in very high rates, so far, relatively few countries have benefited from this technology. Consequently, there are still significant opportunities for promoting SWH in the countries that have not yet profited from this technology.

Solar Water Heating Regional Market Assessment Report on Latin America

Submitted by Raquel Ponte Costa on February 3, 2012

This regional market assessment report focuses on six countries: Argentina, Barbados, Brazil, Colombia, Nicaragua and Peru.

After analysing the solar water heating (SWH) market status (demand, supply, costs and economic and financial incentives) in the respective countries, this report gives a detailed account of the political and institutional framework for the SWH market. It subsequently offers an analysis of the gaps and barriers in each country, alongside a set of suggestions that would improve present conditions.

User’s Technical Handbook on Solar Water Heaters (India, 2010)

Submitted by Raquel Ponte Costa on March 16, 2011

This handbook was prepared in the framework of the Global Solar Water Heating Market Transformation and Strengthening Initiative (GSWH Project), - a project co-executed by the United Nations Environment Programme (UNEP), the United Nations Development Programme (UNEP), funded by Global Environmental Fund with co-financing of the International Copper Association. It was done in collaboration with the Indian Ministry of New & Renewable Energy (MNRE).

Solar Energy for Heating Water in Urban Areas of Egypt (2003)

Submitted by Raquel Ponte Costa on October 30, 2009

This document provides an overview of a project financed under UN GEF Small Grants Programme to boost the use of solar thermal water heating in remote areas of Egypt. The project resulted on the installation of 164 water heaters, reaching 3,790 people, in poor villages and neighborhoods surrounding El Menia, a city in Upper Egypt.

Thematic Review of GEF-Financed Solar Thermal Projects (2001)

Submitted by Raquel Ponte Costa on September 7, 2009

This paper reports the developments of four projects financed by the UN Global Environment Facility (GEF) in India, Morocco, Mexico and Egypt. The GEF chose those countries to develop solar thermal power technology as it has shown to be one of the most cost efficient options for renewable bulk power production, besides being the most cost-effective way of producing electricity from solar radiation.

South Africa: Support Project for Commercial Solar Water Heating

Submitted by Baerbel Epp on May 18, 2009

The Renewable Energy Market Transformation Project (REMT), established in November 2008, was developed to help South Africa address some of the barriers within the renewable energy sector. It is funded through the world bank by the Global Environmental Facility (GEF) and endeavours to fulfil the 2013 renewable energy target of 10,000 GWh, set out by the South African government.
