Best angle for these days (winter solstice) is latitude plus 15 deg. So for me that's 45 + 15 = 60 deg up from horizontal.
I did.I thought he meant like landscape vs. portrait who knows?!
Why should the best angle be latitude plus 15 deg? wanna know more about this...Best angle for these days (winter solstice) is latitude plus 15 deg. So for me that's 45 + 15 = 60 deg up from horizontal.
In a nutshell, because the earth tilts, seasonally.Why should the best angle be latitude plus 15 deg? wanna know more about this...
I wonder why more installations don't have landscape orientation since most shading I see creeps from bottom to top. Might have something to do with more holes in the roof or longer mounting rails.If you have shading that creeps in from the top or the bottom of the array, landscape is best.
Here's an example:
Unless the trees are on the neighbor's land. Then you need to be tactful.Get a chainsaw and eliminate the shading.
The worst tree problems I see are the ones from the HOA. A south facing roof at the adage of the HOA with Palm trees that have grown 40’ high over the years since the installation. I wonder what the winter production is on those.Unless the trees are on the neighbor's land. Then you need to be tactful.
This is why my panels are landscape, in winter, there is shading on the top row, and I only lose a little bit of power instead of the entire row.If you have shading across your panels, if it comes in from the side, portrait will result in more production.
