Everyone talks about the weather

Helene

I’d been meaning to write up something about hurricane/tropical storm Helene, but I gut busy with my own recovery process and wanted to be able to write the whole story. I’m not sure it’s all over, but, here goes.

In the week leading up to the storm here, it became increasingly likely that we would experience some sort of tropical system here. I don’t think many people, including myself, really grasped the magnitude of what was coming this way. A lot of that is history: we’ve had tropical storms come all the way up there (a couple hundred miles from the nearest coast), but it was always just some extra wind and rain. Rarely would a storm have tropical-storm force winds, and barely that.

Helene was different. It came ashore on the inside corner of Florida, and had a lot of momentum to carry it well inland. Still, though, as I looked at the advisories and forecasts early that Friday morning, 2024-09-27, I was still thinking this would just be more of what we’ve seen before.

Wow (Helene information courtesy of the National Hurricane Center).


I lost utility power at 06:27 EDT that morning as the storm approached with tropical-storm force, but Darn Near Hurricane-strength winds. Locally winds gusted to 70 mph, where it could be measured. As power lines fell, weather reporting stations fell off-line en masse. Knowing power was going to be out for “a while”, maybe even hours (?), I shut down all my IT gear and settled down to wait for daylight.
As the light came, I stuck my camera out during a bit of a lull in the heavy rain.

Once things settled down, I ventured out. WHEW that was close. This tree came down and just brushed the house, doing no damage (to the house):

As I looked around I thought it would be a good idea to let some people know I was still here, but while I had a cell signal, nothing was actually going anywhere. Well, can’t do what I can’t do. I took a cue from Nature: as soon as the storm abated, all the usual birds, squirrels, and others were right back to business in my back yard. I took that to mean I should do the same, get back to work and start doing stuff to recover.

I spent the better part of the day clearing that tree from the house, then headed out into the neighborhood. There was a lot of this sort of thing, mostly on the east side of the neighborhood. That’s the direction the winds were blowing from.

The lake level peaked the day after. There is a dock under all that water, which was close to six feet above normal.

By now it was clear that I was in a disaster area and I should try to find a new normal, at least for the foreseeable future. Fortunately my solar panels were undamaged and my inverters have a stand-alone function: I could flip a switch and activate outlets directly on the inverters to power whatever the available sunshine would power. That necessitated the use of some extension cords run in from the garage.

With my Internet router powered up, I found I had full network access. My local carrier, PRTC, was up and running without any apparent issues, so a big tip o’ the hat to them.

The magnitude of that accomplishment became even more clear as I fired up my laptop and tried to get into systems at work. The data center itself was unharmed and had full power, but communications were out all over the place. Private lines, MPLS, two independent ISPs, all were down at times. As some things came up, I was able to connect (via PRTC) to our New York location and route back south. Our network team moved mountains (and often deferred moving their own personal moutains) to work with what we had and provision a circuit with another ISP that was up in record time.

Meanwhile, I settled down to a pattern of tree clearing, checking in on work and anything I could help with there, and eating back-packing meals (my camping aspirations came in handy – I had no shortage of hot meals). Here’s a few of my favorite things:

As luck would have it, we’re only about 3 miles from the electrical substation, and most of those lines are out in the open with little to fall on them. The Sunday after the storm I went to bed shortly after dark (might as well) and was awakened by a “peep” that the CO2 detector makes when it powers up. After just over 2 and a half days we had power back here. I didn’t want to be too optimistic, but I got up and moved the refrigerator from the currently-inactive solar power feed to utility power.

That was a Big Moment in getting things back towards normal, but checking the Laurens Electric outage map still showed that most all of the county was still without power. It’s a bit ironic that usually our utility crews are going to Florida to help with storm recovery, but now we had crews coming from all over to help us here, including some from Florida as their recovery efforts wound down. It would be a full two weeks before all power was restored to the county. Again, a Big tip o’ the hat to our utility crews and the crews that came from all over to help us.

The day after the storm I called several tree people I knew and left messages. I’d been able to clear the tree in the back yard from the house, but another tree had developed an ominous tilt towards the house that it didn’t have before. Fortunately one of the tree guys was able to get here Tuesday and lay it down. That became another tree-clearing project for me. I didn’t want to tie him up any more than necessary to assure my safety, knowing that there were probably still trees on people’s houses.

Having no real reason to go anywhere (I had food, water, and communication), I didn’t venture out until a week after the storm. I didn’t want to risk getting in the way of recovery efforts. As I headed into town, there were areas where you could think nothing had happened, but then just down the road there’d be tree bits piled up on either side of the road. Or utility poles that were leaning over (and weren’t before). Utility crews were working in many places.

Most businesses were open, including the supermarket, although there were bare shelves here and there and they were unable to process credit cards. Fortunately the bank was open. Bar&chain oil was in short supply (and I was about out), but I was able to find some to feed my chain saw.

It was about a month after the storm when I had opportunity to visit the Laurens County Park where there’s a disc golf course through the woods that makes a nice walk (I’m not nearly proficient enough at disc golf to attempt that course). I believe this goal is a par 6, or was a par 6, it’s probably more than that now.

On black Friday I went in the opposite direction to most humans and spent the better part of the day in the woods at Croft State Park. There were a lot of areas like this:

An enormous amount of work had gone into getting trails cleared and re-opened, with still more to do, in addition to repairs to some of the facilities.

I implied that maybe we’re not done with this yet. North Carolina had things a lot worse than we did here and recovery efforts are still going on. There are places that simply don’t exist any more. And every once in a while I’ll look and think “that tree wasn’t leaning over before”, so there are still weakened trees that are at risk of falling. And one could fall on a power line, but I know what I’d do now.

All in all, we survived pretty well here. None of my neighbors, nor I, had any house damage from falling trees. A few had some basement flooding issues. One neighbor said they didn’t know where their boat was, but it’s not a big lake.

Along the way I made up a list of things to be Thankful for:


  1. That tree I had fall over did not hit the house; that could have been really bad.

  2. I had ample food and water on hand.

  3. With the above, I had no need to travel.

  4. My solar panels were undamaged and I could power things like laptops and the refrigerator off them.

  5. Being able to power the refrigerator meant I did not lose any food.

  6. The weather in the wake of the storm was really pleasant and benign, with lots of sun, light winds, and moderate temperatures.

  7. PRTC (Piedmont Rural Telephone Co-op) was there every time I powered up my router.

  8. Our utility power was restored after just 2 days and 14.5 hours.

  9. I was able to get the tree that was threatening the house taken down in just a few days.

  10. Once communications with the data center were restored, I could resume working from home.

  11. The tree that fell over was one I had my eye on, thinking that at some point I’d have to get someone to take it down. That would have cost a large some of money, probably 4 figures. Helene took care of that.

  12. Water and gas utilities were undisturbed.

  13. While a lot of trees fell over, many more were left standing, and forests are intact.

  14. I will miss my fallen trees, which provided a lot of shade around the house, but I found there were some tree-like plants growing up under the one I had cut down, and it’ll be a lot easier to grow vegetables on the back porch now with plenty of sun. There’s a tree that started itself in a pot on the back porch I can transplant to start taking the place of the fallen one.

  15. Everybody in my circle was safe.

Going forward, I still have a couple large chunks of that tree in the back yard. One I might use to make a place to sit and watch the bird feeders and weather station. Another one is kind of propped up on some limbs. I’m thinking I’ll leave that one where it fell (again, it’s in a good place to sit) and carve the storm name and date on it as sort of a monument. And I added chainsaw wood carving to my list of things I might do when I retire; I have a good bit of raw material laying around now.

I actually did take a shot at a little chainsaw carving. I figured my first attempt would be grotesque and hideous, even frightening, so I attempted to carve a bit of a Halloween decoration:

Boo.

Cold Creature Feature 2018 #1

The title says it all: cold.


It’s pretty rare that we get ice on the lake here like that. I took a cautious step onto the ice, about 30cm from the shore and about 4-5cm of water depth. It was probably frozen all the way to the bottom, but I still broke (or cracked) the ice. Don’t try this at home, especially if you’re heavier than a small corvid.

For all the cold and ice, the wildlife is still here. This Kingfisher was still fishing:

and ducks were still out on the water.

And, of course, the obligatory Great Blue Heron picture:

First winter storm of 2017

As often happens, this area is right where things change, and just a few miles can make a difference between the 4-6″ of snow in the counties to the north, and the dusting we got here in Laurens County.


Actually, I saw the first snowfall a week ago on December 31, 2016. We had to go to 9500′ over Oconee County to find it, but it was there, and it was falling, even if it wasn’t reaching the ground.

Awash

The weather is finally turning more seasonable. New Year’s Day was just warm enough to go out and get the new boat permit stickers wet.

I’ve never been out on the lake when it’s been up this high, at least a meter above normal. I was able to take a “short cut” and turn out to the right across the dock when I left the boat ramp.

And there were some other interesting things to see out there.

I wish I had more time, because there’s a lot more lake to explore out there right now.

Talk about the weather…

Yes, here it is, Boxing Day, temperatures in the upper 70F’s:

…and I’m sitting around out on the lake in shorts.

This picture is also notable because it was taken in a place on the lake that wasn’t lake before. All the heavy rain and runoff has created some more “lake” to kayak on.

Rain

We didn’t have nearly the rainfall that areas to the southeast had, and few problems. I saw a total of 7.13″ of rain here at the house, and the lake is definitely higher than I’ve ever seen it in the last 16 years that we’ve been here.

Sunday, as the rain was ending:

but the runoff continues to come in from the north. On Monday:

I wouldn’t be surprised if it goes even higher (not sure at what point the spillway kicks in), as it’s usually 2-3 days after heavy rains to the north before things peak here.

Solar power update

So far, our solar power system has provided a little over 65% of our electrical needs. I’ve been keeping a spreadsheet of the daily electric meter readings (delivered, which is what we got from the electric company; received, which is what we shoved back to the electric company; and net, the difference, which what we’re paying for). Add on the power produced by the solar panels, and I can calculate what our consumption was and how much of that was covered by the sun.

We had a string of cooler and sunny days, and without the AC running, we were able to push that electric meter backwards a good bit. I calculate that we had about 11 days of “free” (in quotes, because the system still hasn’t paid for itself yet) electricity, with our surplus offsetting some days when we had a deficit.

As winter comes, the days will get shorter and that will eat into our production, but then again we won’t be running the AC, so we should come out ahead.

Bluejay goes green

No, I’ve not changed my plumage or species affiliation (yes, there is a Green Jay). It’s more in the human sense that I’ve “gone green”. I’m now harvesting most of the electricity my house uses from what falls on the roof.

What it is

How I’m doing this is with a grid-tied solar power system. This consists of a bunch (26) of solar panels on the roof to collect energy from the sunshine and convert it to DC electric current (kind of like what you get from a battery, but up to around 400 volts), two inverters in the garage to convert that to AC household current, and an electric meter that measures power going both ways, to and from the electric company.

Because we’re still tied to the electric grid, we can draw power from there when the solar panels aren’t producing enough power for our needs, like at night or when it’s too cloudy. At other times, when we’re producing more power than we need, our excess flows back into the power grid to help power our neighbors. Through the magic of “net metering”, we get credit for any power we push back up the line, and only pay for the “net” usage; that’s why we have the electric meter that records power going in each direction. Not all electric utilities do this, and some don’t credit power you send them at the same rate as what they send you, but Laurens Electric does.

Getting the project going

I actually started this process back around the beginning of 2014, but things got sidelined last year due to a family member’s medical needs. I started by contacting a number of installers in the area that I google’d up, getting quotes and reference lists, checking BBB, etc… I awarded the job to Sunstore Solar in Greer, SC because they’ve been in business a good while, I’ve seen their people in the media (so I had no qualms about them being who they say they are: always a concern when you meet people via the Internet), and they were very accommodating of my constant questions and delays (one installer I was communicating with just stopped returning my Emails).

The project went through several iterations, but we settled on an 8.5kw (that’s the amount of power that can be produced at any given moment, best case) system, which should just about cover our needs based on my electric bills.

I had another delay while the roof got re-shingled. I didn’t want to put a bunch of 25-year solar panels up on a roof that was already 16 years old, so that had to be done first.

The total cost of the project (not including the roof) came to just shy of us$40k. That’s a big chunk of change, but tax credits will return more than half of that. I just have to wait on the next couple years’ tax refund checks. Taking that into account, and the savings on my electric bill (over the course of a year, the solar power should cover almost all of it), we should break even after around 8 years, and after that, for the rest of the 25 year life of the system, it’s all savings.

The money is just one reason I did this, of course. In fact, in business, an 8-year ROI (Return On Investment) would probably get nowhere. Getting power from just what falls on the roof, with no carbon or nuclear, is the other big reason. Now, I realize that my paltry few mega-watt-hours ain’t gonna even show up on the digital readouts at the power plants, but, like a lot of things, ya gotta start somewhere. As more and more of us do this sort of thing, we will make a dent in the environmental impact.

Installation

The installation began on 8-June with the arrival of two trucks worth of installers and parts. Some of the guys started on the roof, marking out where the panels would go, while the rest of them went to work in the garage installing the inverters and all the wiring to hook it all together.


Before long my roof gained a set of pimples:

and the garage got covered up with conduit:

A note about what all that conduit is for: one has the wires bringing power down from the solar panels themselves, and going to each of the two inverters, connecting at the bottom of the disconnect switches below the inverters on the right. From there, another set of wires carries the now-AC power over to the small electrical panel on the left. There the output of the two inverters is combined. Then that has to be fed to a disconnect switch on the outside of the house, before coming back in to the main household electical panel.

Because this is a grid-tied system, there has to be a ready way for utility workers to disconnect the system when they have to work on their lines and equipment. They can shut off the power from their end, but they need to be able to ensure that no power is feeding back the other way, which can be a hazard to the workers. The inverters are designed to detect when utility power shuts off and to shut themselves down automatically, but having worked in a lock-out/tag-out environment (where energy sources have to be secured and locked out for safety), I understand the need for a way to ensure that, yes, this wire is really dead and will stay that way.

Anyway, back up on the roof, the racks that will hold the solar panels go up:

and then the solar panels themselves;


According to the spec sheet, those panels weigh 18.6kg (41 lbs.). Yeah, those guys worked hard to get this done.

Eventually all the panels made it up on the roof.

Not being one to be up on a roof myself, I understand why they had all those ropes there. The guys working on the roof were very careful to stay tied off, and it paid off as no one fell off. That would have thrown the whole project off.

By the end of the 3rd day, everything was installed, the area had been cleaned up, and a brief “smoke test” had been accomplished.

Now we had to wait on the county building inspector to come and inspect. That happened on Friday of that week, and didn’t take long. Actually, most of the time was spent by me pointing out the components and what they did. I suspect that the inspector had prior experience with these guys’ work, and knew just what he was looking for. He said it was all “neatly done”.

The last hurdle was Laurens Electric. I was thinking that, since this is a co-op, I own it and could just call ’em up and make it happen, but that wasn’t necessary. Once they got the report from the building inspector, they came out and changed the electric meter. That happened on Tuesday of the next week.

A couple days later the SunStore folks were back to formally commission the system on 18-June, which included connecting the inverters to my network so they could report back data to the manufacturer’s (SunPower) site, where I could monitor the operation and production. When we built the house, I was smart and put a network drop in the garage. Unfortunately, I put it on the opposite side from where the inverters ended up.

I said that the solar power shuts down when utility power goes off, but the inverters I put in do have a provision to provide power via a separate circuit directly from the solar panels in that event. This can be used during an extended utility outage to run a refrigerator or charge phones, so long as the sun is shining. Those outlets are mounted right below the inverters.

Early results

So far, the system is performing to expectation. With the current heat wave and running the air conditioning almost all the time, we’ve been getting a bit over half our electrical power from the solar panels. As the weather cools off, I expect that will increase, even though the days will be getting shorter. In fact, we had one day when the heat wave broke (briefly) and with cooler temperatures (mid-80’s F) and good clear bright sun, we got 92% of our power right from the sun.

There’s nothing on the inverters that’s accessible from the local network by default (they just talk out directly to the manufacturer’s portal), which is a good default setting (too many equipment manufacturers don’t even give a first thought to security), but after doing a bit of research, I found that they will speak modbus (a protocol used in industrial control and building management systems, and which I just happened to be familiar with due to my work around the data center) if you turn it on using the manufacturer’s software (SunnyExplorer). So now I’m able to read data directly and add it to my weather web site on my The Sun page. You’ll probably notice that you don’t see the green “Inverter 1” line on the graph. Both inverters have the same configuration of solar panels, so they’re generally almost identical in output and the two lines lie right on top of each other.

You can too

If you’re interested in doing this sort of thing, I suggest you contact some installers in your area. Each situation will be a bit different: different electrical loads, different siting, different financing… It would be good if you could provide a year’s worth of electric bills, or at least the kWh and cost, so they can design a system to meet your needs. Do check the specs carefully on any proposed system: at one point, I had two quotes where one was double the other; turned out that the cheaper one was also 1/2 the capacity of the other.

The future

Right now we have gas heat and hot water; everything else is electric. The next project is going to be the HVAC, and I’ll be looking into something more like a heat pump with gas backup, rather than just straight gas heat. I’ve got room and inverter capacity to add several more panels to cover that if needed.

One thing I wonder about is how we’re going to pay for all the wires and equipment that makes up the electrical grid. Ultimately, if we all put solar panels on our roofs, producing enough power for each of our needs, and if net metering continues as we have it here, there would be no money going to the electric companies because our “net” usage would be zero. Yet we’re still using the company facilities to keep us suppled when the sun isn’t shining. Maybe the way some utilities reimburse for power (different rates for what they provide vs. what you provide) is the answer, or maybe just some fixed fee for being connected to the grid. I’m sure they’re thinking about this.

Another technology that’s coming into play is batteries. Tesla recently cannon-balled into that market with household batteries to be used with renewable energy sources. Theoretically this can enable you to completely disconnect from the grid if you have the generation capacity to store enough power during the good times and battery capacity to get you through the bad times.

Some time when I get an ambition attack, I’ll put another network drop in the garage by the inverters and eliminate that cat6 wire stretched across the ceiling.

Conclusion

I’ve been wanting to do this for a long time (at least since before my Sister put up solar panels several years ago – sibling rivalry?). Finally, I’m there, and I’m glad I did it. I was taught to not leave a mess, and I’m hopeful this will help clean up some of the mess my being a productive member of this society has caused.

I think I begin to understand, just a bit, what it must be like to be a farmer. The farmer’s crops, and my power production, are at the mercy of the weather. When the clouds roll in and I see that wattage drop to next to nothing, well, there’s not a darn thing I can do about it. But the sun will shine again :).

Winter storm #1, 2015

The first winter storm has rolled across the lake. Just a mild coating of ice here, but by all accounts, it was much worse in other areas.




I don’t think the bluebirds are using this house right now, although they can do some amazing maneuvering to get in and out of places:

Ice and snow always drives a lot of traffic to our bird feeders. Gotta have some creature content:

The promise of Spring? Maybe?

Update: Here’s a few more pics from around the lake:



Don’t get too excited, you can see robins around here pretty much year-round. Hey, where do you think they fly south to?

Snow in November??

In the 30+ years I’ve lived in upstate South Carolina, USA, I don’t think I’ve ever seen snow on the ground this early, November 1st.



While out doing some errands, I decided it’d be a good day to make a pot of my chicken-pantry soup (chicken, and whatever else is handy):

Bill of materials:

  • 1 chicken
  • 2 lb. carrots
  • most of a head of cabbage
  • bunch of parsley
  • 1/4 an onion (usually use more, but that’s what I had)
  • 1 bunch of garlic cloves
  • bunch of celery
  • 1 15oz can of peeled whole tomatoes
  • 1 lb. frozen corn
  • Oregano
  • Italian Seasoning
  • 2 bay leaves
  • Basil
  • Heat to a boil, then let simmer on a low boil for a few hours or until everything is cooked. Serve with noodles and crackers.

    My cared-for thinks this is a good idea, too.
