Robaroni,

I don't have the numbers yet, may never get them, haven't been on fixed tilt for that long. I do feel I was getting around 15 percent boost with a 4 season tilt for last 3 1/2 years. I really had to get one year in the bank before power company would give me a full year of productivity, credit. There year starts on Feb first.

If an individual wants to harvest the sunlight that’s falling on their property and sell it for a profit, that’s their American right.

teddy,
Nice location, I like the water and building in it.

Getting 12 cents over your rate is fantastic! We get the same rate as our cost which is still better than most places.
The 180 degrees, is that an east/west orientation?

I like your location.
Last month we used 1,600 kwh but we have a Chevy Volt we charge it 2 to 3 times a day.
Each charge takes about 12 kwh the first two charges are complete charges (total 24 kwh). The third charge is usually a partial charge.
This saves us so much gas but it does add up at the end of the month. Since mid Feb we have saved over $1,700 in gas and driven 10,504 EV miles. We fill up with sun solar power.  We just put gas in the Volt that is the first time we have been to the gas station for almost 2 months. We live away from town or we might not use any gas like lots of Volt owners.

PB,
One of my friends told me that Chevy plans on coming out with an EV that goes 200 miles on a charge by 2016.

I think it's great that you're saving so much on gas.

Ted, What cutoff dates are you using for your pie chart? I'd like to generate my own, and it would be interesting to see a comparison to someone else's chart. My 4.4kW system only went online on August 1st, so I'm just in the early days of collecting data. I passed the 1MWh milestone in just under 2 months. Averaged 4.4kWh/kW in August, 3.4kWh/kW in September.

TackyTeddy,

What really bothers me, is how Chevrolet got there bailout, sorry. I've gone the Prius route, 60 miles a gallion is not bad. When the Volt battery is discharged, it's mpg is around 32. I really don't care about mpg, I drive a yellow Hummer below.

I supply compost to the weekend farms here in Arizona where I live. This was a year ago.

Cool compost!

I do not want get into politics. Most days we use no gas at all and drive over 80 miles each day Prius just can’t do that. We are getting about 200mpg right now. We really like the Volt very comfortable and young kids will see we are a elect car and try to take us on the line they usually get surprised.

where2 10-05-13 07:45 PM

Unfortunately, at current fuel prices, even 60mpg won't justify the payments versus the 40mpg (city) I'm getting in my paid for MkIV TDI station wagon. I refuel the little red wagon once a month for $64. Costs more to insure it, than it does to drive it.

pinballlooking 10-05-13 08:05 PM

It would not make sense for you to change cars.
We will drive the Volt 25,000 to 30,000 miles a year that has a lot of potential for savings.
But with any EV they have to be right for the people that need it. You really need to evaluate your exact situation to be sure if one is right for you. It really works for us but that will not be the same for everyone else.
I love not sending so much of my money to countries that produce oil.
