What is the cost and benefit of using solar panels as an energy source for my home?

Specifically, how much does it cost to purchase, install, and maintain a solar panel? How much of my energy can I tap out of it?

I live in Phoenix, Arizona. It supposedly rains four days a year here.

I’m in the middle of putting in solar/wind to offset the power needs of a 75 unit condo in St Thomas.

Cut to the chase. Solar systems, with batteries to store power for use at night and inverters to change battery power to 120v cost about $7 a watt installed

in Phoenix you’ll get about 30 watts a square foot about 10 hours a day

a 1000W panel, at $7,000 installed will run 10 100 watt light bulbs or (maybe)) an energy efficient refrigerator.

do the math
