The backbone of my home LAN has been 1 Gbps wired Ethernet for decades. The wired backbone is the fastest part of the network while the WAN and WiFi have typically been a fraction the LAN speed. Because the wired network is fastest, I run wires to each Access Point, getting the wireless traffic onto the wires ASAP for the best performance.
WiFi versions 5, 6, and 7 were released in 2013, 2021, and 2024 respectively. When WiFi 6 arrived, I upgraded the (3) APs with the U6-Lite model for a nice speed bump. WiFi 6 was finally “fast enough” that I can’t recall carrying a computer to the wired connection since.
On February 19th, I cross-graded my fiber internet from CenturyLink to Quantum’s. Improvements include shedding the need for PPPoE and getting two public IPs. That timing coincided with WiFi 7 hardware availability so I also picked up a U7-Pro.
To capitalize on the new WAN and WiFi speed, my aged USG-3P router was the slow link so I also upgraded it. Now when I plug into the wired Ethernet, my speedtest results are consistently within a couple percent of the 940 Mbps service cap. Today I carried my M3 laptop around the house to measure the speed of each AP and was surprised to see that WiFi 7 can nearly saturate my WAN connection…when I’m sitting near the AP with no obstructions.
February 26th was the first day of 2025 that I produced more energy than I consumed.
I typically start producing surpluses in late March, but an unseasonably warm (55°F) sunny day combined with the new panels moved the timeline forward.
Update (March 23rd): despite every day of the past week being mostly overcast, I have still produced 8% more electrons that we consumed over the past week.
Over the years I’ve read enough citations that I’ve accepted it on faith that solar panel performance degrades about 2% in the first year and then 1% every year thereafter. Today I had a chance to test that.
Yesterday afternoon I hauled 6 new solar panels up onto my roof and wired them up. Today they’re producing so I spot checked against the production of my existing 290W panels from 2016. The rule of thumb above plus math suggests that those 8 year old panels have degraded about 9% and likely produce about 290W * 91% = 264W. The new panels are rated at 405W so I’d expect each old panel to produce 65% as much as a new one.
Today is an overcast day, which may affect production differently on the new versus old panels, but when I average the production of 10 old panels to 210W and divide that by the average of the 6 new ones at 320W, I get 65.6%. I find it very satisfying when reality matches theory so closely.
A question I’m often asked about my solar is, “how exactly does Net Metering work?” Here in the state of Washington, the rules for Net Metering are enshrined in RCW 80.60.030. Go forth and read, if you’re the nerdy type. For everyone else…
Every year on March 31, my Net Metering kWh balance resets to zero. When the sun shines I harvest kWh. I also run the heat pumps, toaster oven, and charge my phone and car, all of which consume kWh. If I consume more than I produce, I pay my utility (Seattle City Light) for the kWh they provide, just as everyone else does. If I produce more kWh than my house and car consume, then SCL adds those surplus kWh to my Net Metering balance.
In practice, each year in April I produce as much energy as I consume. From May to September I generate surpluses and build up kWh credits. As winter progresses my solar production falls off and I start depleting the kWh credits. In most years, I exhaust my credits by January and have to start buying kWh.
On March 31st, if there’s any kWh credit balance, it gets wiped away as a free gift to SCL. Therefore, under net metering it rarely makes economic sense to produce any more kWh than one consumes.
My average consumption for the past couple years has been about 2,000 kWh more than I produce, resulting in bills of about $400 per year. That is why I just spent $900 on 6 new 405W solar panels to grow my array. With a rated capacity of 2,400 kWh, I expect them to produce about 2,000 kWh per year, getting me very very close to my target of Net Zero energy.
In the summer of ’24 I replaced my North roof (project info). A complication was that the roof was under my solar array. The following graph explains another complication, the cause of my desire to add more solar panels:
The blue bar is my household energy (all electric) consumption and green is electricity to power our electric vehicles. In most years, I produce enough solar (yellow) to nearly power the house. In the last two years the house power consumption has been less and that extra solar was car fuel. I’ve calculated my Levelized Cost Of Electricity at $0.05/kWh. That’s a substantial discount from grid power so it’s advantageous to buy more panels and produce more fuel for the cars.
As part of the roofing project, I removed and rebuilt my solar array (details here) and upgraded two of my subpanels. What I didn’t know when I did the work in the summer of 2024, was that the soon-to-be-adopted 2023 electrical code requires that all electrical panels have a SPD (Surge Protective Device). By the time I scheduled my final inspection, the newer code was in force and that was the only correction Inspector Friendly required of me.
Despite not being required (grandfathering), I had already installed a SPD in the main panel, since it seemed to me like really cheap insurance. I had also installed a Midnight Solar (MNSPD-300-AC) SPD in my PV combiner box, so now I have 4 SPDs. It feels a tiny bit excessive, until I think about how much it would cost to replace a panel full of AFCI/GFCI combo breakers.
First they befriend you online. They provide an extraordinary level of online attention and [usually] romantic interest. They casually “let slip” how much money they’re making from their crypto “investments.” They encourage you to also make money investing in crypto. After investing a little bit to test the waters, you earn unbelievably good returns. They have fattened up your confidence with time, a romantic relationship, and investment gains. After you invest more, they ghost you and both your money and relationship is gone.
The “pig” in this story is the victim and the butcher is a Chinese captive working in a forced labor camp in Myanmar or Cambodia. These scams particularly target the elderly, so do your part and raise awareness with those you love.
I have a Lectric XP 2.0 e-bike I purchased in 2022. I ordered it with the cargo package (front and rear racks & baskets), intending to use it to reduce car trips for local errands and grocery shopping. Without any planning I can easily carry home two grocery bags on it. With a couple bungee cords, I can carry home a fair bit more.
The rather basic single-piston brakes with 160mm rotors that came with it are good enough to stop the bike and I on most terrain. However, I live in Seattle and we have good sized hills out here. When riding down a hill with a load of groceries, a fair degree of planning is required to bring the bike to a stop on time. It seems Lectric was made aware of this deficiency because the XP 3.0 has upgraded the brakes to 180mm rotors and hydraulic brakes.
Today I upgraded my XP 2.0 with a TEKTRO 203mm rotor on the front and I replaced the Zoom single-piston calipers with XTECH HB-100 hydraulic dual-piston calipers. The improvement in stopping power was immediately noticeable and I’m looking forward to testing my next grocery run.
Since I wrote in 2019, the biggest tax prep companies continue to spend tens of millions to prevent making tax filing simple and easy. They’ve been fined for bait-and-switch, hiding the Free File service they were paid to offer, and overcharging Free File eligible taxpayers. Instead of giving Intuit another nickel, use Cash.app taxes, a local preparer, or file paper returns.
At my most recent donation, Bloodworks NW informed me I’ve now donated 4 gallons of blood. They tell me, “each gallon pin represents another eight lives saved.” I tried to corroborate that statistic and the nearest I found was from the American Red Cross who say that a single donation (1 pint) can save up to 3 lives. Each gallon is 8 pints (units).
It would be fun to know how much I’ve donated in total. I previously donated at Carter Bloodcare when I lived in Texas and the American Red Cross when I lived in Michigan.
Compared to rushing into burning buildings, donating blood is an easy and reliable way to save lives. You should consider joining us 2% of Americans who do so.
At 5AM on Friday morning, we set out for the Snowgrass Hikers Trailhead. All proceeded according to plan until 26 miles off the paved road, a sharp rock tore a 1.5″ gash through one of my tires. I used my tire repair kit to insert 5 plugs, greatly slowing down the air leak. That was sufficient to hold air for about 10 miles, so we turned around and headed back towards civilization.
Upon hitting blacktop, we also got cell phone coverage. I called Tesla service and they would flatbed my car back to Fife, WA and replace the tire. Expecting that to take about 5 hours, I declined to explore my options. The two nearby rural tire shops had nothing in the correct size, so we headed towards I-5 and started calling every shop between us and Chehalis.
Les Schwab in Chehalis claimed to have a matching tire in stock. When we arrived, they had a Continental in 245/55R19, but it was the wrong series. They insisted they could only replace all 4 tires. My tires are nearly new, no thanks guys. Another call and Discount Tire in Lacy (27 miles North) had the correct tire, series, and size, so off we went again. The plugs held, Discount Tire replaced the tire, and shortly after lunch, we once again had 4 good tires.
For the second time, we set off for the Snowgrass Hikers Trailhead. As we got into the I-5 freeway, a car 5 car lengths ahead of us threw up something which left a quarter sized chip in my windshield. We pressed on and arrived at dusk. We camped overnight in Motel Tesla.
On Saturday morning we hiked over to Berry Patch Trailhead and headed North. We took the optional scenic detour to Goat Ridge and found the lookout is now ruins. We continued North and took the Lily Basin Trail #86. We stashed our packs and scooted out to Johnson Peak (7,257′) and tagged the summit at noon.
We descended almost bee-lining towards Heart Lake (a better route than our ascent), returned to our packs, and then visited Goat Lake. The camp sites were all full, the lake shore was crowded, but the lake was empty. I dove in and found out why: it was still ice-cold. We filtered drinking water, ate our first dinner, dried off in the sun, and then pressed onwards.
About a mile past Goat Lake we found an empty campground and set up for the evening. It was a lovely evening, cool and brisk and we slept well under my MSR tarp tent. In the morning we set our sights on the summits of Old Snowy Mountain (7,900′) and Ives Peak (7,920′).
Based on our previous days experience and the forecast, we again left our packs behind and headed for the summit of Old Snowy with just an extra layer and water bottles. Oops. As we ascended the wind picked up and the exposure made us regret the choice. To keep warm we picked up the pace and reached the summit before 10AM. We did not loiter and scurried right back down.
50° with 30-40 mph winds. Brrrr…
Being separated from our layers prevented us from hiking the ridge over to Ives Peak. We descended on the PCT, retrieved our packs, and then hiked out Snowgrass Trail #96 to the trailhead and our car.
