you can’t run a 60 watt 120 volt light bulb with a 60 watt 12 volt pv it will take 10 of them.

on my 5kw 120 volt inverter at full output needs 50kw 12volt going in.
here this will help ya…

still NOT green
&
still only last 20 years

There is some loss (as heat, whch can be used) but it is small.

To put it another way, 5kw = 416 amps @ 12v or 20 amps @ 250 v.

or nellis sending \$100m to save 1m a year thats a loss of \$80m over the life of the panels.
or take the dumbies in florida, just in todays news. it just dosen’t add up.

The fact is that installing solar panels for your home or business can cut your electric bill to \$0 today. For example, if you spend \$200 per month for electricity, then you will spend \$81,979 over 25 years, including a low annual price inflation rate of 2.5%. No matter how you calculate it, you will save money with a \$5,000 to \$25,000 solar panel system. Remember, you can pay the utility for 25 years, with annual price increases, or you can pay a lot less with solar power.

To do something about this today, visit FreeCleanSolar.com to search a nationwide network of 500 local solar installers. You can also find information about state solar rebates, federal tax credits, solar financing and leasing, system costs and the benefits of going solar. The bottom line is that many home and business owners can afford solar power today.

you wrote “dropped from \$10.80 per watt to \$7.50 per watt”
that’s at 12 volts. 5kw @ 12 volt system “i.e. going in to the inverter” is 250 watt @ 220 volt “going out”
thus a 5 years pay back is 50 years. & the panels last about 20 years & less with a tracker ot concentrator.

not green buy the way there made…..
