diy plug in home portable solar panels?

[Skavatar]

My wife got her M3 last Feb, I just got my MYLR a two weeks ago. We live in hot and humid Houston. We're not quite ready to install roof top solar panels yet. Our roof is still good for another 5 years or so. I've been researching diy plug in portable solar panels like in the video (maybe just 2 panels) to supplement our electricity use during the summer when it'll be +95'F and +80% humidity.

small grid tie in inverters that only work if it detects power from the grid, so no back feed with the power goes out.

only 2 panels so not to produce more electricity that we can use.

roll it out from the back porch, and plug it in when I get home at 3pm and unplug when the sun goes down around 800pm, my backyard is on the East side so entire yard is shaded around 7:30-8pm even though the sun isn't fully set.

no electricity feedback if grid goes down, very detailed explanation of this guy's diy plug in tie in grid solar panels

So when there is a power outage you cannot get power from your solar system...

correct. just trying to supplement the electricity used by the A/C during the summer. last summer during the +100'F summer our electric bill was around $300. and that was with just the M3. now we've added a MYLR.

our electricity hardly ever goes out for too long. during Hurricane Ike we lost power for just a few hours, the 2021 week long ice storm we only lost power for a few hours. we have a Centerpoint substation just a few miles away and they've been quick to restore power.

That depends on the inverter design. Sunny Boy SMA inverters allow for 120/240v AC direct from the inverter if the grid goes down.

When it's hot, vertical panel might generate more power (cooler than at an angle). Plenty of youtubers and companies testing it out. Interesting, probably not for me.... but interesting. Presumably something similar could be done with wind etc.

On my roof, I have East and West vertical panels generating more power
than my South panels (who are almost flat with 10 degree inclination).

In the moorning, one hour after sunrise, the West panels produces almost the same amount than the East panels,
so I assume that the light reflection on the roof is the explanation, as the azimut angle becomes less and less optimal.

My verticals panels are against a wall, and there is not too much wind during the day, except aroud sunset,
so I don't think that wind is really a factor, however natural cooling is more efficient for vertical panels.

Monitoring the temperature behind my panels is something that I plan to do.
