Solar Power

One solution for off-the-grid living in Arizona.

Our little off-the-grid vacation place has solar power. It’s an extremely simple system that consists of two 120-watt (I think) solar panels mounted on the roof and four deep cycle batteries in a little cabinet. The panels are attached to the batteries with a charger. Whenever there’s sun — which is just about every day in Arizona — the solar panels charge the batteries. All we do to maintain them is make sure there’s enough distilled water in the battery cells.

The building has both AC and DC power. That’s a weird thing that we decided on when we first set up the place. It’s a very small place with just one room, a loft, and a bathroom alcove. There are very few electrical appliances, and they’re split between AC and DC. On the AC side is an iHome clock radio (the kind you can put an iPod in), a 700-watt microwave, and a 600-watt single cup coffee maker. There are also outlets that can power a small ShopVac or laptop. Everything else is powered by DC power: 9 small light fixtures, the water pump, and a ceiling fan. (Do you know how hard it was to find a DC ceiling fan?) There are round DC power outlets everywhere there’s a standard AC power outlet. The fridge, stove, water heater, and furnace are all propane gas.

Theoretically, we can run the whole place on DC power with gas. On very short stays, we don’t even bother with the fridge. But since the batteries are hooked up to a 2000-watt AC inverter, we usually turn on the inverter so we can use those AC appliances and outlets when we want to. We have a little meter that plugs into a DC outlet to monitor the amount of juice in the batteries. At night, the power level gets low, but never too low to run lights or watch a movie on a laptop with power connected. And, in the morning, even before dawn, there’s always enough power to run my coffee maker.

It’s a great system. It cost about $2K for Mike to design and install and it meets all of our limited needs. I’m certain that if we built a house up here with more conveniences, a system just three or four times the size — perhaps supplemented with a small wind generator — would easily meet those needs. After all, it’s cool enough up here that air conditioning is not required in the summer — especially if the house had an energy efficient design that kept the hot air out. And if the sun isn’t shining, the wind is probably blowing.

Today, while relaxing with a book, the radio suddenly died. I checked the little DC meter and saw that we had plenty of juice — 15.4 volts, in fact. That’s the highest I’ve ever seen it. I went out to check the inverter and found lights blinking on it. Consulting the manual revealed that we had too much power for the inverter to use. The system is designed to shut down when available power exceeds 15 volts.

Oddly enough, to get the AC power to work, I had to come inside and turn on a bunch of lights and the ceiling fan and run the pump for a while. In other words, I had to throw away excess power. Once I got stored power down to 14.8 volts, I went outside and turned the inverter back on. Everything worked fine.

Keep in mind that this is a very small system and there’s no tracking on those solar panels. The panels are fixed to the roof, pointing southwest. (Imagine how much power we’d pull in if the panels were set up to track the sun?) It was about 2:30 PM when the problem occurred; it’s now almost two hours later and the sun is lower, so I don’t think the problem will reoccur.

My point is this: Arizona is a perfect environment for solar power, especially for small to moderate use. There’s no reason why solar can’t be set up to at least supplement power coming into an on-the-grid home. And for an off-the-grid home with modest needs, it seems to be a perfect solution.

So why aren’t more homes built with solar as part of the standard builder package?

On Product Registration Questionaires

Answer these questions so we can sell your contact information to others.

About two weeks ago, I went on a little shopping spree at Best Buy. One of the things I walked away with was a Nikon CoolPix S550 compact digital camera. I needed it (yes, really) to replace the 2-1/2 year old Canon PowerShot I kept in my purse. The PowerShot had become unreliable (to say the least) and, although it has several features I really like, it had to go.

Yesterday, while weeding through the stack of paperwork that came with the CoolPix — including both a full-length manual and Quick Start guide in Spanish — I stumbled across the registration form. “Return this card to register your purchase and enter our $100,000 Give Away VI,” the yellow folded sheet proclaimed. So this morning, as I sipped my first cup of coffee, I began to fill out the form.

Where they get the idea of calling this a “card” is beyond me. It’s a sizable sheet of paper, folded in thirds, with registration form fields on one full side and a third of the other. There are 30 questions.

I began filling out the form with basic information like my name, address, and e-mail address. They’d need this information, I reasoned, to contact prize winners. I also provided basic product information, such as the date of purchase, model purchased, serial number, and place of purchase. Then I answered questions, via check boxes, about the features that influenced my purchase decision and the other similar products that I owned or planned to buy. This is all basic market research stuff.

Next they asked about my skill level as a photographer (I checked “advanced amateur”) and computer skills (“advanced”). But I paused when I reached question 15: “Would you be interested in a digital camera course?” I would, but I didn’t want Nikon trying to sell me one via annoying e-mails or mailings. Still, I checked Yes.

More marketing questions followed. Is the camera for business or personal use? What business am I in? What kind of computer do I use? What other brands did I consider?

Then came the big departure from questions about the camera. The questions started getting personal. How many people in my household? Ages? Genders? What is my occupation? My husband’s? What’s our household income? What level of education did I complete? What credit cards do I use? Do I own or rent my home? How many magazines do I subscribe to or buy at newsstands each month?

Finally, the list of things we might do — 64 of them! — with check boxes. You know the options: Shop by catalog/mail, donate to charitable causes, have a dog, have a cat, own a CD-ROM drive, tennis, sailing, power boating, foreign travel. The list goes on and on. This is basically a check list so they know who they can sell your information to.

And that’s what these registration forms are all about — a way to get you to voluntarily provide personal information so they can sell it to others, who will then bother you by stuffing your mailbox with dead trees (as Miraz would say) or filling your e-mail box with special offers and links to their Web sites.

To confirm this, there’s some fine print at the very bottom of the form. It looks like it’s in about 6-point type; I needed my cheaters to read it:

Thanks for taking the time to fill out this questionnaire. Your answers will be used for market research studies and reports. They will also allow you to receive important mailings and special offers from a number of fine companies whose products and services relate directly to the specific interests, hobbies, and other information indicated above. Through this selective program, you will be able to obtain more information about activities in which you are involved and less about those in which you are not. Please check here if, for some reason, you would prefer not to participate in this opportunity.

If I’d finished the questionnaire — which I did not — I’d check this “opt out” box. But would that really protect my information?

So I decided to save the 41¢ postage — you didn’t think they’d cover that cost, did you? — and just shred the damn questionnaire.

April Flowers

Experimenting with a new camera.

I like to keep a camera in my purse. You never know when a photo opportunity might crop up. While some people would be perfectly satisfied using the camera on their phone, I’m a bit picky. So when my 7.1 megapixel Canon PowerShot became unreliable earlier this month, I replaced it with a 10 megapixel Nikon CoolPix.

[A side note here: I cannot believe how advanced and inexpensive digital cameras have become. This was the least expensive of all the digital cameras I’ve purchased, yet it has more capabilities than all of them except my Nikon D80 digital SLR. And the pictures speak for themselves.]

I took the camera along on my afternoon chores at the horse corral and snapped a few photos of what’s currently in bloom around my yard. It’s been warm out during the day — in the 80s — and although there was some rain to the north of Wickenburg today, it remains dry here. Still, there are more wildflowers this year than I’ve seen in a few years.

A close-up shot of some desert marigolds, including a flower bud. Unfortunately, the guy who takes care of our yard pulls these out as weeds.

Globe mallow. (Remember, I’m still playing with my camera, so I’m experimenting a bit more than usual.)

Brittlebush. These took seed in our yard, grew into bushes, and flower every year.

Fix or Repair Daily

It’s not always easy having stuff.

I have too much stuff. That’s not under question. But I’ve learned that one of the problems with having too much stuff — besides finding places to store it all — is keeping it all working and in good repair.

Vehicular Responsibilities

Take, for example, my two motorcycles. Bought brand new in 1992 and 1996, I rarely ride them. I simply don’t have the time. So they sit in storage, gathering dust while the gasoline in their tanks turns to varnish and their batteries die. I’ve tried battery tenders and gasoline stabilizers, but every time I want to take one of them out, I have a heck of a time getting it started. The solution, of course, is to sell at least one of them and I’ve made the decision to do just that. But I still have to get it running and bring it over to the motorcycle guy who said he’d sell it for me.

My new old redneck truck — nicknamed the “Brokeback Mountain Truck” because of the way its 14-year-old pearlized red paint looks pink in strong sunlight — required a bunch of small repairs to get it up to operating standards for the long trip it’ll take me on in May. That bunch of repairs, which I thought would cost about $500 to $700 cost a whopping $1,500. Ouch! The mechanic, who I trust, says it’ll run a good, long time. It better. It’s my first Ford. Some of us know what F-O-R-D stands for. (If you don’t check the title for this post.)

To be fair, we drove it this weekend to Howard Mesa and Flagstaff (so far) and it’s running okay. Sure, its 8-cylinder engine is a dog and the Ford steering is about as loose as you can get, but get it up to highway speed and turn on the cruise control and everything is satisfactory. I’ll have accurate fuel burn numbers when I fill up in Chino Valley on our way home.

Mummies in the Attic

But the ongoing source of our repair efforts is our little vacation cabin. Its exterior was built by people who know how to use the necessary tools and materials and they did a reasonably good job. The place is sturdy, anyway. But after adding plumbing, electrical, fixtures, appliances, and furniture to make it a home way from home, the problems began.

First it was the mice, who seemed to invade the premises every time we left. That means a thorough cleaning and disinfecting each time we arrived. I don’t know about you, but after a 3-1/2 hour drive, the last thing in the world I want to do is spend four hours vacuuming and washing floors and countertops, and furniture. The mouse moved into the walls, so we’d often hear them scurrying around at night. It took a long time to find and seal up all the holes where they were coming in. When I got sick of dealing with the humane mouse traps, I resorted to rat poison. The worst night we ever at the place was the night after Mike threw rat poison into the roof rafters and sealed up the holes on either end with steel wool. All night long, the doomed rodents were running back and forth over the ceiling.

And yes, there are now mouse bodies in our ceiling. But thanks to the dry Arizona air, they mummify quickly.

Split Pipes

We were still battling the mouse problem when the plumbing problem began. We’d used PVC piping which, due to our low water usage needs, should have been fine. Trouble is, if you don’t drain the pipes properly, the water in them freezes up in the winter. That causes the pipes to expand until they break.

Our first Christmas at the cabin gave us our first plumbing repair job. We brought everything inside, turned on the water, and turn on the pump. Within seconds, water was gushing out of the wall.

Mike spent most of the next day repairing the broken pipe. When he was done and everything was closed back up, we turned on the pump again. Another pipe was broken. He fixed that one the next day, on Christmas Eve. So yes, on that trip, we didn’t have running water for more than 48 hours.

Despite our best efforts to drain the pipes on departure, this happened again, to a lesser extent, on our next visit. Mike got very good at repairing pipes.

The following Christmas, Mike came prepared. He replaced all the PVC pipes with copper. Unfortunately, there had been water in the toilet valve and that had split. (We had installed an RV toilet to conserve water.) So we had to manually flush with a bucket of water.

On our most recent trip, we discovered a crack in the pump. We bought a replacement and hope to repair the old one as a spare. But when he went to fix the toilet — after replacing the pump — he discovered that the replacement part he’d bought for that didn’t have the piece he needed. So we continue to bucket flush.

Other Problems

We’ve had other problems with the place over the years. There was the mouse nest in the furnace that prevented it from staying lighted until the nest was removed. Before fixing that, the cabin actually got down to the low 40s at night.

And then there was the poorly set windows and doors. I spent a whole day with a caulk gun filling cracks with clear caulk to stop the cold wind from finding its way into the building.

Otherwise, everything has been fine. But now I know why Mike doesn’t like going up to the vacation cabin. Every time we go, there’s something that needs to be fixed.

At Home

Our house is just over 10 years old now, at that age when little things start needing attention.

Original light bulbs all over the house have been dying lately. The guy who built our house probably had stock in the local utility company. Every single light fixture in the house has either 3 or 4 bulbs in it. The master bathroom, which has a long countertop with two sinks and a vanity, is lighted by a row of 16 bulbs. When we moved in, there was a 150-watt bulb in each one. That’s 2400 watts of lighting with the flick of one switch. We replaced all those bulbs with 40s and put a dimmer switch on it. I don’t need to get a tan in my own bathroom.

We’ve had a few minor leaks in the past few years. We’ve needed some paint touchups inside and out. A few of the ceramic tiles between the kitchen and front door are cracking but not loosening up. The appliances are still all working fine, although I know that when they start dying, I’ll replace them with better rated equipment and leave the foo-foo brand names for another sucker. (I’ll take my old Kenmore dishwasher over the JennAire I have now any day.)

So I’m waiting patiently. Something else will break shortly — I can feel it in my bones — and I need to be ready to take care of the repair.

Greetings, Blog Readers!

I’ve been meeting blog readers…in person.

I’ve been blogging pretty regularly since 2003, writing about the things that go on in my life, the things I’m thinking, the flights I’ve been making. I’ve been sharing photos and videos and stories. All the time I do this, I don’t really think about the people who read what I write. They’re a nameless, faceless group, scattered all over the globe.

At least they were. Lately, some of their faces have been coming into full focus. How? I’m meeting them in person.

I met three of them up here in Alaska over the past two days: Keith, Deb, and Marcus. Keith didn’t say much about the blog, but Deb and I discussed some of the things I’ve written in a bit more detail than I’d expect. And Marcus laughed with me about misused apostrophes, including the one on a local restaurant’s take-out menu, which lists Pizza’s. (You may recall that I linked to Apostrophe Atrophy on March 15.)

This is odd. I’m over 2,500 miles from home and meeting people who already know me more than I expect. And they still want to talk to me, if you can believe that!

Anyway, I just wanted to take a moment to say hello to the blog readers I haven’t met yet in person. Maybe I’ll meet some of you one day, too.
