Saw this advertisement for an Anton Bauer Salt-E Dog power station running off a sodium battery. 9kWhr, 6000 watts output, Sodium Nickel Chloride, 4500 cycles at 80% dod, 300kg 661 pounds! It’s marketed for television or movie production and no listed price, so probably expensive as an early...

Everything is an optimization calculation. Changing orientation to get a slightly better evening capture is free. I also bought a $7 closet mirror from Target that I'm going to experiment with and has already given me a little boost. I'm sure I could find a robo-window washing system to clean...

As a followup. I'm observing that lengthening days don't necessarily help a solar array at fixed, uniform orientation (South heading 180, 23 degree inclination). This is because the extra morning and evening sun is when it is ENE and WNW (let's say compass headings of 80 degrees and 280...

Scary if true. I'll take you at your word. When I lived next to the Bay Bridge, I do remember the particulate being a little more black though.

Installer said 22 or 23 degrees. But I haven't taken my protractor out to measure.

I'm in San Francisco. Most of the particulates are likely car exhaust, but some of it is dust from other sources. Despite our access to clean ocean breezes, when it's dry, we get a slow buildup as anyone who observes their window or their car parked outside can attest.

As identical as you can imagine. See the screenshot for the dates mentioned. I have carefully observed high cirrus clouds (that were absent those days). You can see the effect of cloud cover being more dramatic and would reflect in hourly fluccuations. Look no further than the morning of the...

I just got rooftop solar on April 5. Where I live in California, soot is a slow and steady phenomenon. April 12th, April 13th, and April 14th, 3 identical cloudless days, I noticed my production was slightly decreasing day-over-day about 0.7% each day on average. But over these days, the amount...
