Problem is, even in high solar radiation areas, it’s not a very “power dense” source. Also, it’s a SUPPLEMENT, not a replacement.
The costs associated with generation of solar go way beyond just the PV cells. Want to hook into your home? Better have an inverter, an isolation switch so you don’t backfeed onto the grid in case of outage, etc, etc...and you’re looking at about 25-40K for that kind of system.
Unless you’re paying over a grand a month for electricity, it’s hardly worth it.
Inverter and automatic transfer switch and grid-tie interface setup is well under $10K, sometimes $4K if you have a smaller solar setup.
What you really do is capture solar generated electricity in 12 volt deep cycle marine batteries. Currently $66 at Wal Mart. Get 10 of them. Run your TV and radio on 12 volts is easy. Lighting is easy because 12 volt is standard for RVs and boats. You go a marine supply store. Power tools will need an inverter unless you hook up a gasoline engine to an air compressor and use air tools I won't deny that other items also will need inverters and that you have to scale back your electricity consumption to go 12volt DC. I have visited homes where this is put into practice
Refrigerator - you run on propane same as your stove
12 volt DC power supply for computers or better yet get a laptop that runs on 12 volts DC
