Solar Power: Step 78

Step-by-step, one small piece at a time the system comes together. The special quick connects came in, but one wire ended up too short, and so I have another on order. Nonetheless, the panels all were producing 70 volts per series pair. They are now wired into the DC breaker panel.

The panels covered for safety. There is no way to turn them off, so
when the sun shines they are "hot" and can potentially cause a shock.

I needed help to raise the panels and put the legs on. In theory, they will not have to be touched for 20 or more years. Panels are quite inefficient converting only about 10% of the power that hits the panel. In 20 years I'll bet 2 panels of this size will replace the 10 I have now.

The panels up and working.

Inside the electrical shed work continues. The inverter weight 66 pounds. I had to build a shelf to place it on while I bolted it to the wall. All that remains, I think, is one solar panel connector, two battery cables and wiring it into the AC side.

Final Failure & the Simpsons

I told the inspectors I wouldn't be back until Wednesday afternoon, but when I arrived I found 3 yellow sheets of paper stuffed in my front door jamb. I failed my final inspection on 3 counts.

1. The inspector couldn't enter the building.
2. There needs to be 3' of flat runnout at the bottom of the stairs, and some of the gravel had sunk down a bit.
3. Lack of adequate hold-down on the porch roof.

Items 1 and 2 could have been handled had I been there. In fact there is nothing left to approve inside, but the inspectors have every right and are naturally welcome to make sure they caught everything. The reason I know that there is nothing left inside is that I had a final inspection 3 months ago in order to get occupancy and at that time there was a list of items to complete: front and back handrails, porch lights, finish siding, and a couple of little nits. Nothing about the porch roof structure, which was finished at that time.

Frankly, I've worked hard keep from using Simpson Strong-Ties in visible locations. The reason being that most of them are as ugly as sin, and meant to be used inside walls and covered over. On an exposed structure like a porch they really can detract from the look. Their popularity stems from the combination of increasing code requirements and cheaper construction methods and materials. Use a Simpson Strong-Tie and everyone is happy because the burden of failure falls on them. It's a CYA sort of thing.

I was delighted when my first final list made no mention of additional hold-downs on the downhill side of the porch roof. The engineer had made much of the uphill connection at the house, but was silent on the lower portion. In the absence of direction my builders had fastened them with a single #10, 4-inch, stainless steel deck screw. My real frustration at not being there for the latest final inspection was that I might have been able to distract him or at least point to the last inspection report and kept the focus on those few items.

When I described the whole situation to my octogenarian neighbor, Roxy Nelson, he laughed. He had commented to me long ago that he thought the roof was liable to blow off in a stiff wind. As a machinist he had used plenty of metal in his place, and he was skeptical about my solution.

I did finally look up some data and the likely uplift on each rafter is 350 pounds. Trying to find the pull-out resistance of the screw was more difficult, but it seemed clear that 350 pounds was a stretch. Moreover, it seemed clear that the real point of failure would be the screw pulling through the cedar. So, in the end the house may be uglier, but safer.

Solar Panels (photos)

Today I finally got to put the panels up...or rather down. The rack system I bought from Uni-rac, "the leaders in the industry," but it had some issues. The panels have legs to raise them to the requisite angle, but it's not really possible to install the panels on the raised rack. Here's why:

• The panels themselves provide the third arm of the triangle. Without the panels in place there is no real frame. A catch-22. Can't install the panels on the floppy rack. Can't make the rack stiff without installing the panels.
• The panels clamp from the top using special clips. The panels must be held in place to install the clamps.
• The clamps between panels hold both panels and thus two panels must be done at one time.

After trying to do this at an angle, I gave up, layed the whole mess down and installed them easily in minutes.

A rack of solar.

Every time I turn around I find I need another specialty part. Most recently I opened up to find the panels have specialty, quick-connect electrical cable pre-wired. Quick if one has this kind of cable around. I don't. It's now on order.

The panels look diminutive because the electrical shed is 10' tall at
the face. The panels are 3' x 5' each and the two racks together is
about 30'. The panels weigh perhaps 30 lbs. each, so I'll need help
raising them.

Adding DC (photo)

I've started working on the solar system. It's not really a good time of year to be doing solar, but I've had the panels for over 2 years now, and I'm interested to put it all together. Besides, it does add a battery backup component, which is a good thing to have during winter storms.

DC (solar) side.

Exterior is Finished (photos)

There was a bit of a delay waiting for new cedar planks to cover the back wall. We ran out of salvaged, cedar barn planks, but it was amazing that we got 3 sides done in old wood.

Jordon (top) and Jason put the final plank in place.

The back (north) wall gives a sense of what the house would have looked
like if it had all been done in new wood. Dull, uniform, and lacking in
character.

choice to have no windows (only skylights) on the north side.

It finally got cool enough to try baking bread. The results were quite good, but the house got quite warm.

Ready for Final

I finished installing the front and rear porch lights and the rear handrail. This completes my tasks prior to final inspection. As soon as the porch roof and siding are done, I will call for final inspection. Even though I've been living in the house for over 6 weeks now, completing these last couple of items was a big relief.

If It Weren't for Re-work... (photo)

I like it in the dark, ask any of my friends. That's why I hadn't really planned for front and rear porch lights. I thought I would put them in after final and after some experience living in the house. No dice. Front and rear lights are required, I think because of the associated stairways.

Thus I was forced to tackle the problem early. It involved removing a couple of panels and figuring how to get to a switch for the rear light. The front one will be automatic with a motion sensor, and a manual override in the attic. Should be complete tomorrow.

Progress continues. It looks as if there is enough salvaged cedar siding to cover the west, south and most of the east sides.

Stair Rail (photo)

Among the handful of items needed to final the house is the need for "grippable" handrails. The grippable standard is pretty tight, and the 2x4 top rail on the stairs didn't cut it. So here is my solution.

Round rail meets code.

Porch Roof (photos)

Hay season is over and the porch roof starts. It is made from the aluminum roofing salvaged from the nearby barn that we dismantled 2 years ago. Looks like we have plenty of material. Combined with the old siding the house has a weathered look as if it has been on the land for years.

Work Resumes

Hay season ended and work resumed on the house.

Water Shed (photo)

Around mid-July hay season began and work on the exterior of the house ceased. In the meantime I did more work on the watershed, completing the exterior paneling and framing up two of the four barn-style doors.

Day Two: Coffee

I arose this morning to the sound of rain. Padded across the wood floor, over the tile and into the kitchen. I lit a fire in the stove, and threw in a few chunks of wood. While the water heated up, I ground coffee by hand in the coffee mill. About 30 minutes later the coffee was perking, and soon after I had my first cup of coffee accompanied by English muffins toasted directly on the stove top.

It's all good.

Fang Moves (photos)

I carried him by hand in the cat carrier the 200 yards to the new house, and set him down in the living room. He quickly emerged and checked the permiter several times, howling all the while. He returned to his cage as if it were some magical portal, and if he only went through it again, he would return whence he came.

Fang quickly finds a sunny spot.

After a while I left him. When I returned he was sleeping on the bed. It will take him some time to adjust, but it's a far, far better life for both of us.

First Night

Today I got a verbal okay to move in. There is a short checklist of items to complete before final, but for now I will never sleep in the old manufactured home again.

It's a year and one month to the day since groundbreaking, but really over two-years since I embarked on this project.

I celebrate by spending the evening on my new porch. For an instant I thought I saw a forest fire or an emergency vehicle in the opposing hills, but it was only the moon's big orange face rising through the fir trees. I watched him ascend as I sipped some fine Portland whiskey. The silhouettes of a few deer moved across the lawn not 30 feet away. I stood for a time at the deck rail. I could hear their munching as they pulled on the new growth. After the moon had risen in full, and his face calmed to luminescence, I retired, snuggling under the layers of down, the clean night air rushing over my face, and the moon shadows projected on the ceiling high above me. The house snaps and creeks as the timbers cool and gain moisture. A new house with old bones telling stories of another life.

Clean Water

Today I found out that my water tested potable. I'd been drinking it for a week anyway, after having shock treated the lines with chlorine and then activated the UV light. You've got to have faith.

Always willing to try new suppliers, I chose Coffey Labs in Portland lab instead of the usual one used around here, Alexin. Maybe Coffey is used to dealing with professionals who don't need a lot of hand holding, but if they are going for home testers, they need some work. First they forgot to send my bottles, and I had to email and remind them a week later. Then the test bottles they sent came in a makeshift box, with a foam liner. No testing protocols were given, other than to keep the samples chilled in ice during the trip back. They didn't even include a return address label.

Despite all this, I managed to get my samples double-bagged and sent overnight, apparently without leaking, and arriving at the required temperature.
