Unintended consequences of Solar that we see

I'm continually getting questions, frequently from people I don't really know as some intermediary told them about what I was doing.
Or the truck delivery guy while they are waiting to be unloaded, looks up and sees the PV panels, "wow solar; does that run your whole shop?!" - (yes it does!).
 
I can see that point, if you are making enough power in the winter with the tilt, you will make plenty in the summer anyway at the same angle.
Different loads at different times and there is a thing called snow. I did a video about tilting panels in winter, it showed a neighboring town that installed grid tie to lower the electricity cost to run the sewer plant. Fixed angle with snow on top and cold temps (-20°F) led to 10 days of total lost production for that system until it finally thawed while I was producing 50 Kwh/day with clear skies and no snow on my panels.

If you are grid tie, sure, fix the angle. If off grid or maximizing off grid usage, tilting in areas of snow and cold temps may mean the difference between running a generator or switching back to grid.

As a matter of fact, the best angle where I live for winter does get the best snow sliding off :)
i usually do not have to sweep them off, but am prepared for it.
 
...or fitting a long handle to a push broom... ;)
My next array will be over 16 foot high.

Takes a long broom handle. :ROFLMAO:

I have plenty of snow to move when it does snow, from the drive and 3 businesses we own. I sit in a heated truck cab with the radio on.

I'm not standing out there with a broom when it is -20°F and the wind blowing clearing snow off panels. I live by the motto; work smarter, not harder. ;)
 
My main array is above the patio (it was a mini horse corral).
My next upgrade will be the roof on the school.
I prefer a standalone ground mount but have to make compromises.
slight hijack so feel free to pm instead, but what's the mounting structure- looks very neat.

You can always just clear the panels of the snow, I have found at -20 there is no hope of these panels of clearing themselves. Just get a broom and in 20 minutes your back to producing energy.

Covering some of my outbuilding roofs with solar panels have stopped my roofs from leaking, to replace the roofs it would of cost nearly as much as the panels and fitting the panels was quicker and easier...win-win :p

I wonder if some roofing will last longer just due to the shade the PV provides(cooler under the panels), protection from direct heavy rain and reflection of some of the UV.

been thinking along similar lines - roof for lean to is almost as cheap to make using solar panels as roofing materials.....
