Snowlar Panels and a slightly off topic use for surplus energy
(05-13-2019, 03:45 PM)OffGridInTheCity Wrote: This is my first full year of steady system.  By steady I mean its fully formed/hooked up.   I actually got my highest production a few weeks ago (46.2kwh for the day) and then its started dropping to 44.5'ish over the last 2 weeks and I think its because the temperatures have gone from 70s to 90s F.   So 20deg F hotter appears to be a 4% drop in power.  

As another tidbit -  I live in severe smoke area of Northwest USA.   Last year the smoke was so thick that you couldn't see beyond 4 blocks for several weeks - like fog.   I 'think' this caused 15-20% PV power drop.   I'm looking forward to pinning this down better if it occurs again this summer.     I note this because clouds cause 50% power drop and I would have thought smoke would be similar to clouds in terms of blocking the sun.    Not sure yet.

I was over Washington State in August 2017 when there was a lot of big wildfires in The Cascades, we were the other side of the mountains in Stanwood. But the smoke moved up and over. We spend some time in Seattle and a few other places and one stage it even blocked out Mt Rainier. There was a particular day we were in Spokane and it was so thick as couldn't stop coughing. Even down by Snoqualmie and North Bend we could still see the smoke.

There was a few days when it turns the sky red and all the birds were quite, found it very eerie.

If memory serves i think they had nicknamed it Smokezilla or something like that.

Still we had a great time visiting our friends in their new place, we used to spend a lot of time with them when they lived on Whidbey Island, loved it over there.

Hoping to get back over again soon, got some other friends down in Salem Oregon that want us to head over too.

Another great new record day of production 39.26kWh. Slowly climbing can't wait to see a 40kWh plus day.

Yea - last summer we  (southern Oregon USA) had a few weeks that looked like this:


and another few weeks about 50% as bad.  Folks are not happy with Forrest management/fire management.

Yea that's just what it was like when we were in Stanwood.

Are you much further down from Salem?

Another great day, not quite as high as yesterday but very close.
Produced 38.86kWh today.

The pick is from Medford Oregon, which is southern most part of Oregon right near the Oregon/California border.  
Salem is a few hundred miles south.  Seattle is few hundred miles north.

LoL yeah some of your states are bigger than all of the UK, point to point most southern Lands End to most northern John O’Groats is only 603 miles, shortest driving distance was 874 miles, but a new route has been found on google maps that only 866 and avoids all motorways.

So pretty small in comparison.

Just for clarity, and despite what many little englanders would have you believe, the UK extends a fair few miles further North than John O'Groats.

Wow.. great production! I am going in the opposite direction ironically. The angle of the sun is hitting the top of some pine trees so I am loosing about 2 hrs. now vs. in March/April. Being my 1st season with the system I knew it would be close.. if the array was placed just a few feet closer to the house i would not have the issue. So now I have a call into the tree surgeon to remove the offending tree.

I take it that you have 0 obstructions - clear sky view?

What an idiot I am sometimes  Dodgy     When I said "Salem is a few hundred miles south" I was conflating Sacramento (CA capital) with Salem (OR capital).    Sacramento is south,  Salem is about 150miles north of Medford.    Sorry for extra post here - just didn't want to leave untrue statement on the thread Smile

True it's commonly regard as John O' Groats, in Caithness i think is the most northern town in mainland Scotland, Dunnet Head is a peninsula that i would think makes it the most northern bit of mainland Scotland about 11 miles northwest of John O' Groats. Herma Ness or Out Stack, in the Shetland Islands i guess would be the most northern part of the UK. But I'm probably wrong, what would a southerner like me know the furthest North I've ever been myself was Aviemore.

Another fair day slightly lower production again.

Managed 36.74kWh.

Just a little shading on the bottom right few panels early in the morning. But as I have micro inverters I get the most from all the panels.
