Another factor in your favor is the fact that it is cheaper to install solar at construction then to later retrofit on an existing house. I also have a tip for you, it’s great to build to be off the grid but the best way to pay off the equipment and help everyone else is to reverse meter you excess sales. One of the Pillars of the designs we do is to oversize the alternative energy by 30%. The reasons go like this.
1. Over time (20-30 years) homes or buildings need more power as we get more stuff. Example most homes built between 1960’s and 1980’s had 100 or 125 amp service, today the standard is 200 amp so homes have to spend to upgrade usually 3-5 thousand. By planning for this you can use the excess to payoff using reverse metering and grow as you need it.
2. Even as prices come down, usually it is cheaper to oversize now than to do it later, because of inflation- so even though the amount of over sizing is 15% more in cost you still get the benefit of 30% overproduction because it’s the other stuff needed for a system besides the panels that add so much cost, think inverters, battery backups, rectifiers, mountings, permitting and so on. Over sizing now only adds a little cost because all these other things can take a wide range of different sized instillations so the main thing you are buying when over sizing is panels, everything else is already figured in.
3. Suppose you want to someday have an electric car or like myself a Fuel Cell Car ( and I am tell you I want one now and am on the waiting list) over sizing gives you the ability to provide for production of your electricity for the EV or FCV.
4. Over sizing gives you the ability to keep your battery backup fully charged more, meaning you can reverse meter during peak times of the day when you make more money from the reverse metering.
5. The payoff is usually quicker if you over size, meaning that you are free and clear more quickly and because you can show the over production as a long term income allows you to get financing from the bank much more easily.
For our commercial designs we have found over production to be one of the primary ways to add long term benefits, value and revenue that you cannot get by just sizing the system for you base needs. Many times for commercial we do this by designing hybrid systems that incorporate two or more renewable sources. Say solar for electric production and geothermal for heating and cooling, or solar and wind and so on. It provides better overall security for constant power and allows you to provide for additional redundancy and therefore sales. That’s POLY-GENERATIVE SYNERGY.
Final thing every car company that is going with FCV's for 2015 rollout is developing systems to fuel from home, so having a little extra power for my Elecrolyzer means I can then be ready to fuel my FCV at home overnight.

My only hope is that the Chinese don't become the ones primarily producing these as it will be yet another industry that is lost from North America.

I do have a problem with utility owned generation! First, they get the benefit, not the homeowner and you'll pay a premium to boot. Second, due to low module efficiencies they have to aquire a lot of land and all that entails while most peoples roofs are just sitting there idle.
Solar module and film production are highly automated, it takes very few jobs to produce gigawatts of power. I therefore think it is a net gain to have China commoditize them. The only reason i could afford to buy is because they have driven the price down to the point they are affodable to the average Joe. As long as we do the research and develop the processes here, that is what is important for us to keep. The number of jobs lost to manufacture is infinitesimal.

I also like the point you are making concerning who produces these panels because this is a discussion we need to be having here in the United States and around the world. Do we as a country want to lead the world in manufacturing this and other renewable technologies, or do we want to let others gain the competitive advantages that will make alternative energy the economic driver of the 21st century. There are few easy answer, but it’s a conversation we need to have.
I am really glad cost is coming down because now more people like you can make the Alt. Energy Shift that we all want for this planet. Right now the solar industry is in a developing period, as always the market place and capitalism will shake out the kinks and it may very well be that we will continue to let others takeover the mass production of these technologies.
My biggest concern is that people take the time to research and find the best product, at good prices that meets their needs. Congratulations on going solar, I am sure many people would love to know what area of the country you live in and what type and size of system you have, because a lot of people have questions out there. When it comes to making an Alt. Energy Shift the more information the better.

Apple does all it's innovation here and builds in China, as does Dell. I-Pods, I-phones, etc. would not be affordable if they were made here. Unless workers are willing to take a substantial pay cut and the EPA is willing to look the other way, solar would not be viable for at least another decade, if that. One cannot ingore basic economics no matter how noble the goal.
The unfortunate side of technology is increased efficiency. Robots took the UAW from 350,000 members to 35,000. There used to be "steno pools", typists, and secretaries, computers killed all that. Solar just doesn't create that many jobs, and will destroy them in the long run. There have actually been books written about this long term shrinking labor phenomenon.

I live in WA across the strait from Seattle, a stones throw from Canada. I can drive into town and take a ferry to Vancouver, BC. My wife is going there next week in fact!
My system is 42 Canadian Solar CSP-230P for a total of 9.66KW. I use a SMA SunnyBoy SB8000-US 8KW inverter. It should supply 90-95% of my electricity. Payback less than eight years. My electric rate is 6.5 cents/KWH, rather low as rates go. Those with higher rates and better state incentives could see faster paybacks.
My system is self installed. If I had to pay a contractor I wouldn't have done it, it would never have paid for itself. I posted a new thead on government funding idea's for plug and play consumer solar, (buy it, take it home and hook it up), this is the only way to go in my opinion.
