It helps to have extra space to install them.

Do you have any hurricanes, tornadoes or other very strong winds in your area?

FWIW

More square footage too. Mine are about 1 meter x 500mm, so 50 watts for a half square meter would be about 10% efficiency.

Occasional tornadoes but mostly straight line winds, including thunderstorms that can produce more than 74 mph (hurricane force) outflow boundary wind.

Then of course we have the kind of wind where if it has been calm for a few days, all the loose Walmart bags and trash ends up caught in all the fences..

I don't think you can tornado proof it, but with 74mph winds... wow... you would need to anchor the base into solid concrete and ensure the panels are securely bolted to the base.

Yep. But out of numerous installations I see springing up all over various developments, I see clear lack of any engineering studies or workmanship. Such as one house I go past on the way to and from work every day, that has panels on the NORTH side where they will never, ever get much solar radiation.

And i suspect that any of the severe cumulonimbus type straight line wind events will turn most of those panels into deadly projectiles.

Worse, apparently there's an entire fly by night marketing industry on the loose out here. They pay homeowners a certain amount to install the things, but then the outfit is who actually owns the panels and who gets the checks from the electric company, not the person whose roof the panels are on. I think the homeowners get a small pittance, but beyond that they don't worry about maintenance or anything else like that..

So it's more of an exploitative "vulture capitalism" racket that goes on.

My solar panels however, are ones I own, as badly mis-matched and piecemeal that the setup has been done, in little 50 watt or so increments, and a rat's nest of wiring.

The bike ride went very well, and 50 watt panels are easily put in the back seat of a truck with the radio repeater hardware in the bed, hauled to sites along the way, deployed in a few minutes, then after the event is over with, they can be packed up and hauled off pretty quickly too

ROFLMAO... where does he live? The South Pole?

South, YES, East & West... also good... but North? Unbelievable!

Sounds like scammers/skimmers if you ask me!

FWIW

I need to take a picture of that house. I noticed the solar panels on the north (and we are at N32 degrees latitude) which is pretty close to the slope of the roof. So around the winter solstice - actually from Halloween to ground Hog's Day - these panels are going to be in perpetual shade.

If I hadn't been preoccupied with other issues, I'd have gotten a picture of it during the Snowmageddon that started on Feb 15th and ran until Feb 19th. the panels were covered in nearly a foot of snow and it didn't really melt until maybe feb 22 or 23

LOL... so not only are the panels facing north, but also in snow country with close to a foot of snow on top of them for several months! (* ROFLMAO *)

FWIW

Normally it's a desert here. We only got about 6 days of snow, then it all melted within about 3 days of warming. the solar panels I think had most of it slough off when it stayed above freezing for a few hours.

But, even here in July, they get maybe 4 hours of sunlight at a very shallow angle to panels oriented that way.

And by late August, the sun is where it never hits them directly.
