$2.70 for one hundred miles. That is the equivelant of 100 mpg. And, if you have solar panels on the roof of your residence, you not only provide energy for your home, but the fuel for your car. Pays the cost of solar back rather quickly, particularly if you are reasonably intelligent, and build your own panels. A 5 kw grid parrallel inverter is only about $2000, and you can get the solar cells for about a $1.25 a watt. A 5 kw installation would cost just a bit over 10 grand.
By the way, JR, can you do basic math?
I don't exactly follow what your point is. At 13.5 cents per kw/h it would be $4, just thought I'd toss that in.
I do basic math quite well. I don't know where you get $1.25/watt it seems to me that $3.50 is about as good as you can do. Buy Solar Panels from Top Manufacturers at Lowest Prices I'm a good sport though, we'll use you figures. I'm going to power my home with your $1.25/watt panels. Here we go.
Monthly usage 2400kw/h. Daily output of a 5kw solar system=16kw, monthly=480kw. Number of 5kw systems needed to power house=5. 25,000 wattsX$1.25= $31,250+$2,000=$33,250. At the price everyone else thinks solar panels cost= $99,750. With a battery system and wiring we could probably add another $3-5k to that. At your price it would take almost 10 years to recoup the inital investment if you don't have loss of output or a hailstorm or other problems. At the normal price that people in the real world would have to live with it would take 30 years to break even with regular from the grid power. Again that is assuming no other problems, like having to replace your roof which would cost extra, unless you have super long life shingles or something. So probably over 30 years. Of course the panels only last what 15-20 years? Not exactly a great deal. I would also have to buy both of the neighbors houses who live next to me in order to get all of my panels to fit and cut down the tree in the front yard which would mean I'd have to use even more panels to keep the house cool. So that'd be an extra few hundred thousand dollars. I think I'll just buy a power plant instead since I'm going to be spending a fortune I might as well power the whole neighborhood and make some money off of my investment.
