In Brazil, people commonly shower in the evening, the water being heated electrically by instantaneous water heaters. As a consequence the national power supplier "Eletrobrás" must hold high power station capacities ready to be able to cover the peak load in the early evening hours. In order to save power station capacities - and thus costs - Eletrobrás has decided to promote the use of solar thermal collectors for domestic water heating. Meanwhile more and more Brazilian households are using solar power for warm water production. The enormous market has already generated a multitude of companies in Brazil which produce solar thermal collectors. The different products are tested and certified in a laboratory at the Brazilian Center for Development of Thermal Solar Energy in Belo Horizonte. The large number of measurement orders from collector manufacturers and the Brazilian climate - the rainy season in Minas Gerais / Belo Horizonte lasts from November to April - have m otivated the planning for an indoor test stand for solar thermal collectors. The equipment for this test stand is financed by the World Bank as a part of the "Brazil Energy Efficiency Project", the United Nations Development Programme - UNDP being responsible for the project management. A substantial component of the testing facility is a solar simulator, which PSE - a spin-off company of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg / Germany - designed and manufactured in the style of the simulator used at the Fraunhofer ISE. This new solar simulator was installed in Brazil in November 2004. In our paper we present the technology and the performance characteristics of this solar simulator developed by PSE.
