"1000 Roofs Programme" - Disseminating Solar Thermal Hot Water Production

As of: September 2021

The project aimed to promote solar thermal energy as a resource-saving and affordable alternative for water heating in selected regions of Brazil. Accordingly, the project partners planned, funded and implemented solar thermal installations in social housing projects. Parallel to this, the project aimed to improve the quality of service provided by local suppliers and maintenance companies. In addition, a national implementation strategy and attractive funding mechanisms were developed together with the project partners to support wider distribution of solar thermal installations. Banks, property developers, installation companies, resident representatives, municipalities and other stakeholders were also involved in the process.

State of implementation/results

  • Project completed
  • Support provided for 43,000 installations (approximately 100,000 m² of collector panels installed) within the context of the national programme for social housing
  • Solar thermal energy working group established as a forum for institutional cooperation among key actors
  • Strategic plan for solar thermal energy 2011-2015 developed; implementation contributes directly to achieving Brazil's climate goals
  • Resolution passed that makes the use of solar thermal hot water production legally binding for one-storey social housing
  • Education and service quality of local suppliers improved through training activities
  • Levels of acceptance and prevalence of solar thermal installations increased through country-wide information campaigns
