3.1 x 106 m² is the area of solar heating collectors installed
In Brasil (84% in the residencial sector; 15% in hotels and
services; 1% in industrial sector)
But this represents only 1.72 m² for 100 thousond inhabitants,
far behind Cyprus (84.4), Barbados (26.9) e Turkey (13.5)
The average increasing rate of installed area in Brasil is 14%,
while in Canadá is 50%, in Germany 39%, France and Grece around 34%.
Solar Heating
Great opportunities to increase the use, both in residential and business applications. We need incentive legislation and credit to drive in this direction.

• PV seems to be the natural solution for small communities electrification far from the grid. But PV solutions has to come together with programs of improving the production
capabilities of the community. If not, there is a risk to have just a waste of resources.
• We do not produce PV modules in industrial scale anymore but producing equipment in
Brasil generates much less CO2 emissions (clean electricity mix)
•With lower prices of equipment, due to technical
improvements and production scale, higher prices of conventional sources and the increasing concern with environmental impacts, the penetration of renewable energies can be higher than conservative nowadays forecast.
• Intermediate and small systems can be economically
feasible in specific applications even with the present price conditions.
• Brasil is already a renewable energy country (hydro and biomass). This can be a barrier to the introduction of other renewable sources if their costs are significantly higher than other alternatives.
• Joint programs between countries and regions, changing technology and
experiences, exploring synergies and
improving production scale, seems to be a way to lower costs and strength the role of renewable energies in the near future.
