Can Solar Panels Power My Whole House-Including A/Cs?

Hello, I’d really appreciate some input on the subject of solar power panels. I’ve ready a lot and I’ve learned
a lot in the recent months by Googl’ing and I realize it’s a big undertaking and in order to generate a small
amount of KWH it takes a lot of hardware/installation. I’ve been very interested for some time in this subject,
not so much for my needs here in California (where my average monthly electrical bill is roughly $65, even
when I run the A/C in my studio from time to time), but more for the time I spend in Rio de Janeiro, Brazil,
where electricity is about 10 times as expensive and where the price per KWH increases every 2 months.
My question is; how realistic would it be to attempt to power a house in Brazil using solar panels?
My question is; how realistic would it be to attempt to power a house in Brazil using solar panels? Of course it
would be preferable to completely power the house with solar power, though partial solar power would also
be helpful. It is hot in Rio 9 months out of the year (sometimes even all year long), and when it’s hot there is
plenty of sun. The cost of electricity is so high in Brazil (roughly 6 times higher than the US…and it goes up
every 2 months or so) making it unaffordable to run A/Cs for most people.
1. Is there any way that I could run between 3-5 wall A/C units in a house, or one central A/C unit for the
whole house (all day and all night) as well as to run the rest of the house’s appliances (fridge, freezer, TVs,
computers, lights, etc) using solar panels? I realize I’m asking a lot and I’m not sure how many KWHs it
would require to run all of the above-mentioned, but is there a chance it could be done by only using the roof
of the house as the resting area for the panels? If so, how much would it cost in hardware/installation to
generate that much electricity?
