When Ontario had coal fired plants, the fly ash was sold to make concrete and drywall. No one worried about the radioactivity except when we tried to recycle some plastic liners from the fly ash hoppers. They set of the portal alarms at the waste plant.

Just a quick question - -pls don't blow it
out of proportion.
As part of the nuclear industry (disclosure) I have a
pretty good
understanding of nuclear plant maintenance requirements. The
question is,
what are the maintenance requirements for solar arrays. It seems
like
they're pretty trouble free on the ISS, but would it be the same for an
'earthly' environment.. For example, could temperature variations, dust,
wind, storage batteries, etc., increase maintenance costs enough to make a
difference?

I think the best answer is, "It
depends".
You are correct that there are a lot of things on the ground that
have to be taken into consideration. It would be foolish to not engineer for
whatever the extreme weather is for that location: the cost per unit of energy
goes up a lot if the entire array has to be replaced after every wind storm.
Cleaning is probably going to be the biggest ongoing maintenance cost,
especially as it will be needed most often in the urban areas where solar energy
can be used with the least line losses. I suspect that dust and biofilms can
really cut into efficiency.
On the other hand, servicing a solar array has
to be much cheaper per unit of energy than servicing wind turbines.

Friends,
I could gather some more information on
the solar powered airport in India.This airport was constructed in record
time.The management Cochin International Airport Limited (CIAL) is very
progressive.In 2013, They erected a 100 kWp to begin with and progressively
raised it to higher levels.
The solar power system is grid connected with no
battery stage.The 12 MWp solar power plant,?comprising of 46,150 solar panels
laid across 45 acres near cargo complex now ?produces 50,000 to 60,000 units of
electricity per day to be consumed for all its operational functions, It needs
48,000 units of power per day.The entire power produced during the day is fed to
the State's electricity grid. The airport buys back whatever it needs from the
grid.The airport has a power purchasing agreement with the Kerala State
Electricity Board. CIAL is a profit-making company . The Company paid 21%
dividend to the investors
Kerala State is sunny. The humidity in the region is
also high. As Mike said ?dust and biofilms can eat into the efficiency of solar
cells. Hot climate with lot of humidity can accelerate the growth of all sort of
little beasts including fungi!
Yes maintenance issues may be humongous. We have
to watch how successfully it operates over periods of months and years. Reality
will set in once the celebrations are over.
India plans to construct 100 GW of
solar power in the next five years. Many consider this as too
ambitious.

You are correct that there are a lot of
things on the ground that have to be taken into consideration.? It would be
foolish to not engineer for whatever the extreme weather is for that location:
the cost per unit of energy goes up a lot if the entire array has to be replaced
after every wind storm.?
Cleaning is probably going to be the biggest
ongoing maintenance cost, especially as it will be needed most often in the
urban areas where solar energy can be used with the least line losses.? I
suspect that dust and biofilms can really cut into efficiency.?
On the other
hand, servicing a solar array has to be much cheaper per unit of energy than
servicing wind turbines.?

Just a quick question? - -pls don't blow it out of proportion.
As
part of the nuclear industry (disclosure) I have a pretty good understanding of
nuclear plant maintenance requirements.? The question is, what are the
maintenance requirements for solar arrays.? It seems like they're pretty trouble
free on the ISS, but would it be the same for an 'earthly' environment..? For
example, could temperature variations, dust, wind, storage batteries, etc.,
increase maintenance costs enough to make a difference?

Hmmmm,
Sounds like solar power will compete
with farming for many acres
of viable crop-growing land. Not so good.

Duke University has rediscovered that coal fly
ash has radioactivity. Is
the next step to call it TENORM? Being a nuke
(disclosure) this is not
necessarily a cause for alarm. However, it could
become the next
radioactivity scare. - Thoughts, opinions,
