Contingency Planning.
A story:
Following the contingency plan was simple when the alarms went off. It was well written, concise and obvious. When I reached my assigned place I discovered the next stop was to read "Green Book Number 17". Green Book Number 17 was difficult to find at first because it was so small. Merely a thick paper cover and a single sheet of paper.
The single sheet of paper said only "Find box 17 on the lower shelf and follow instructions."
Box 17 was one of only a few boxes on the shelves and was about the size of a shoe box, only made of heavy metal locked with a combination lock. Likely the combination lock for the 6 digit number I'd been told to memorize last year.
The top of the box had a 3"x5" card on top that said "Open box while alone in locked room immediately." Simple enough, the room I was assigned for emergency use was just down the hall so I stepped in and locked the door. Everyone outside was going about their duties in an orderly fashion so no need for me to interfere.
Sure enough the number I had fit the box I had. Inside the box was quite a surprise, not what I'd expected at all. A box of syringes, a small mirror, a headlamp, a bottle of rubbing alcohol, a box of sterile wipes, a 9 mm hand gun and 4 boxes of shells. Also a sealed red envelope with INSTRUCTIONS printed on it.
Inside the envelope was a set of simple instructions I found hard to grasp. Simple to list, difficult to execute.
"If you are following instructions which have led to opening this box, the base will be completely sealed in less than 10 minutes. Follow these instructions as quickly as you can, time is against you.
1. Look in the mirror. If the whites of your eyes have any bright yellow coloring find your next in command and give them this box. If not follow the rest of these instructions.
2. Inoculate yourself immediately.
3. Find your next in command and check their eyes. If no yellow is visible inoculate them immediately. If their eyes are yellow at all, shoot them in the head.
4. Repeat these steps for every person in your section of the building.
If in 4 hours no others have developed symptoms use the intercom to begin trying to contact Central Command.

Solar taxes.
One of the steps in this process that I've sort of doubted all along was the claimed tax refund from installing the solar. Well, I did my taxes and wow was I surprised. Not only did I get several thousand dollars back from my taxes for installing solar but I have an even larger hold over for next year because my deductions were too large. So I get a huge return this year (which is very good since it's going to save my ass) and next year I get a bigger than normal return.
At this point my total outlay for the installation is going to be about $13,500 for a 6.72Kwh system. Then I'll get another chunk back for it next year, probably dropping the total price to around somewhere around $11,000. I won't know for a while yet exactly what my payoff period will be for the system, but at the very least it's making it so that my hot tub increase in power use is offset. During the summer I expect to generate quite a bit more power than I use, even with the hot tub, and I intend to make the hot tub significantly more energy efficient before next winter.
So all in all, I would guess that I'll have this entire installation paid off in about 7 years, so then I should have about 13 years of profit from it before I have to replace it.

Power usage/generation Jan 2010
Ugh...I used 926 kwhs last month in addition to the 590 kwhs I generated. I've got to do something about the amount of power that hot tub is taking. It was a cold month, average temperature of 26, but still...that's a crazy amount of power.
Total so far: 2.03mwhs. Woohoo! December is definitely the low month, and that's likely to be true every year.

Data collection
I've really screwed up the data collection for my power. I was going to put together a nice set of data and comparisons and whatnot for the end of the first year with solar, but it turns out I don't have a baseline. I've just been changing things too fast.
Moved into the house in 2006 and didn't have time or money to do anything for winterizing the house. Nice baseline but that's it.
2007 I had two roommates and did some winterizing. Now way to tell which effects apply to what.
2008 I had one roommate and installed a tankless electric water heater and did some more winterization.
2009 I added a crapload of insulation, had no roommates, installed a hot tub and solar panels.
So...no clue about any of the changes. It appears since I got the insulation done and winterized more this year I'm saving an entire 1 therm at the same average temperature.
Clearly I used more gas and electricity when I had roommates by a tremendous amount and I'm using far fewer therms now that I've got an electric tankless but it's almost impossible to tell if I'm really saving money.
I generated 390kw in December 2009 for a total of 1.52mw since the installation in October. I really wish I could figure out what is required for a monitoring system since REC won't respond to my questions about getting a datalogger installed. Sigh.

Home sized battery systems.
http://green.venturebeat.com/2009/12/24/panasonics-new-home-battery-could-store-a-weeks-worth-of-electricity/
Now I've got to save up money to buy one of these and buy my way out of the Xcel contract. This is exactly what I've been wanting.

11/7/09-12/7/09 power generated
510 KWH, still haven't passed the max generated amount of 6686W, but that's not surprising. In theory, I'll generate about the same amount from 12/7/09-1/7/09 as I did this month, because I have the trees cut back more and intend to cut them back further on 12/21/09 which should be the day the most branches shade the roof as the day the sun is lowest in the sky. All of course depending on me keeping the snow off the roof. I need to go buy some implements to make that easier.
I'm missing a lot of statistics here, just getting the bare minimum because otherwise I'd have to take the readings daily just before sundown and I can't reasonably do that. I really wish REC had included a monitor with this system like I asked, even if I had to pay for it. I tried several times to get a monitor put in, but it failed.
So far I've generated 1.13MWH of electricity in 2 months during the winter. I can't wait to see what it generates during the summer.
