Solar Energy in Brazil
– Photovoltaic
• Costs are still high
• Opportunity for stand-alone systems for isolated areas
• Governmental working group is currently conceiving a solar
photovoltaic program
• Brazil is the greatest world silicon exporter, but has no
photovoltaic components manufacturer
– Solar thermal – low temperature (water heating)
• Consolidated industry (more than 15 manufactures)
• Significant market share (replaces electric showers)
– Solar thermal – high temperature (CSP)
• Costs are still high
• There is room for applications at specific regions, such as the
Northeast Region
• Studies are under way to support the development of the basic
project of a solar thermal power plant in the Northeast Region

Final Remarks
 The Brazilian energy policy aims at to assure at least the
current level of participation of renewable energy in our
Energy and Electricity Matrices, while considering its
sustainable development, reasonable prices, energy efficiency
and security as well as access to all population
 Diversification of our electricity matrix is desirable. However
we have to consider (and foster) the stage of development of
new renewables and associated costs
 Hydropower will still have a major role in our system over the
next decades
 Brazil intends to develop its supply resources, including those
in the Amazonian Region, but in a very strict sustainable way,
i.e., taking into account the social, environmental and
economic dimensions
