Yes it´s available parts and all. Companies also install them. Depending in where you live and your intended purpose, solar (most common) wind and even hydroelectic if you have a strong enough running water in the property is possible. I´ll let you research your project according to your specifications:



It´s a general information to give you an idea so that you have the latitude to expand your research as you progress. You can Google translate the pages if you don´t yet speak Portuguese well. Good luck!

Oops! There were 6 links I sent but didn´t materialize! You can always supplement with your own research. Thanks!

Yes, the equipment and installers exist, at least in the Southeast; the farther you get from São Paulo, the iffier both will become.  Solar equipment will be expensive, because while the panels may be produced in Brazil, the photovoltaic cells are imported.  As you're probably aware, Brazil taxes imports heavily.

90% of Brazil's electricity comes from hydro, so there's no climate change related political pressure to diversify, or a heavy carbon footprint to lift.  That translates to no tax breaks or incentives that I'm aware of, even when we have a progressive government.  I certainly wouldn't expect help or encouragement from the current regime. If you want to connect to the grid, you may find yourself needing to educate the local utility first. 

To summarize, like so much in Brazil, it will probably cost more,  take longer, and have a longer payback period than you'd expect now, but if you want to do it enough,  you probably can.

I had a research on that once and a R$20,000 investment on solar panels is sufficient to run a household. 2 years to get your money back... Durability about 20years, according to my research.

I have no reason to challenge you're initial investment numbers.  Our current electric bill, though, runs about $1700/year, and we use a lot of electricity.  There's never a need for home heating in the North, of course, but a two year payback still sounds pretty rosy.

I can´t withstand too much heat. With air conditioning I spend around R$700 a month. Comes winter
the heating bill is almost the same. So the solar panel seems to be a good investment...

Oops - I misread your investment number as dollars.  The numbers are consistent if it's reais.  I'd be shocked if R$20K - $5000 US - would do it, though.

I got the R$20k number from people on U-tube having their solar panels installed by businesses.
