[ RadSafe ] solar advances

[Brennan, Mike (DOH)]

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.

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?
