Building My Solar Kit (con't)
Over here in California, we're getting ready for our second "PSPS" (Public Safety Power Shutoff), which is likely to happen every year for the next ten years or so.
At the time, I started building my solar kit with the goal of being able to power my workstation. But by the time my initial equipment arrived, the PSPS was wrapping up.
Thus, the only thing I had in my kit was a 200W external battery (Suaoki S200 Power Station). This was sufficient at the time, but it wasn't really solar powered. I charged it from the wall, which was limited.
Now, I also have my solar panel:
SUAOKI 100W Foldable Solar Panel
I ended up doing a dry-run, to see how well it works. There's a patch of roof next to a window, which is an ideal location to do this setup.
Looks like I need to get a longer DC cable, because with this particular setup, the panel is partially blocked by the nearby tree. But even with this configuration, I can almost gather enough wattage to power my macbook.
Even with the shadow, I can produce 26 watts. But in order to keep from depleting my external battery, I'll need to get above 45 watts. Just moving the panel out of the shadow a little, like this ...
... brings the input power up to this ...
So that's just enough to avoid depleting the battery. In full sunlight, I should be able to get about 80 watts. And this configuration isn't ideal. There are much better places to set up the panel. But with this configuration, I can actually use the panel while in-doors, so it's a good compromise.

A drastic difference in power gain indeed.
So, the panel won't be at a permanent, fixed place?
Here's to your independent power source :)

I'd love to have a permanent panel. But I'd probably need to replace the roof first.
That's a valid reason :)
Good luck with the panel and the roof fixing.
305 w solar power plus a mppt charge controller.
Absolutely phenomenal.
Efficiency is absolutely everything when you get into the solar game.
Well that and also battery size.
However having the backup plan is absolutely priceless!!!
Really wish I could just set my solar system up and plug in and earn a check for the electricity flowing back into the grid.
I love solar, I always wanted to put solar on the house. Seems such a waste not to have it but I just don't get enough sun here due to trees to justify it.
I wish solar wasn't so damn expensive. I've heard we are on the turning point to a big improvement to solar that might make it more approachable for more situations.
We use a shit ton of electricity, between the pool, mining, central air being on non-stop in the summer. Solar wouldn't even make a dent in our Summer bill.
I'm currently looking into telsa battery packs to optimize electricity costs and have a psuedo generator.
That's a pretty cool solution. I may try something like that before I decide to do a pretty big solar panel installation for most of my house needs.
It looks you got some interest from the cat too! 😂

Participate in the next Power Up Day and try to power-up more HIVE to get a bigger Power-Bee.
May the Hive Power be with you!
