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.

Solar Heat for Industrital Process Technical Report. State of the Art in the Mediterranean Region

Submitted by Raquel Ponte Costa on February 9, 2012

The objective of this technical report is to provide an overview of the state of the art of Solar Heat for Industrial Processes (SHIP), to describe the main technologies existing worldwide, particularly in the Mediterranean, and give recommendations aimed at supporting the spread of this technology. Although there is a very limited penetration of solar technologies in the industrial sector, there is a great untapped potential.

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 Financial Modeling Tool for Domestic Hot Water

Submitted by Raquel Ponte Costa on January 27, 2012

The SWH Financial Modelling Tool is a spread-sheet modelling tool which can be used to calculate the life cycle cost savings of a Solar Water Heater (SWH) unit and the national monetary benefits and energy savings of installing multiple SWHs systems.

Example of Solar Water Heating System Installation in Mexico

Submitted by Raquel Ponte Costa on July 20, 2010

This document produced in the framework of the the Global Solar Water Heating Market Transformation and Strengthening Initiative (GSWH Project), reports the usage of solar water heating technologies in the soccer club Los Plumas de la UNAM in Mexico.

The installations were made in 1996 and have proved to be very efficient and successful. This document includes the technical characteristics of the equipments installed, the advantages, the savings, and maintenance requirements, among other details.

Albania: 75,000 m2 of Newly Installed Collector Area

Submitted by Baerbel Epp on December 29, 2009

Alongside the government, the United Nations Development Programme (UNDP) and the Global Environment Facility (GEF) officially launched a solar water heater project in Albania, with its first workshop in Tirana on the 4th of December. The project titled “Country Program of Albania under the Global Solar Water Heating Market Transformation and Strengthening Initiative” aims at installing 75,000 m² of new collector area in the country and supporting sustainable market growth targeting at annual sale figures of 20,000 m² by the end of the project in 2015.

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.
