I was of the impression solar panels were not quite so environmentally friendly in their production, had a limited lifespan, and their disposal again caused issues.  

This really isn't solving the world's problems. 

If one looks into it, I believe you'll find that in the production of most everything that is considered "green' the manner in which it is produced completely contradicts the practice of sound environmentalism.

You really don't think so?  Notice that the other, more expensive sources of generation in this graph have their own environmental problems.

We were not particularly discussing cost, so you went off on a tangent. 

Let us see if this installation is still productive in a few years, albeit at a meagre 45MW (half the time)  this large footprint does not seem efficient.

Great idea. But maybe won't be working at capacity for a couple  of months until the hot season kicks in.

From the domestic consumption viewpoint that may be true, however, commercial consumption (shops, offices and factories etc.) will take as much as is available and more.

We are always discussing cost when considering power generation.  Lower cost of generation implies more resources available for mitigation of environmental effects.  

 

Also, the costs including environmental costs of various alternatives for generating power can only be considered relatively, which you haven't done.  Are the environmental costs of PV power higher than that of coal, natural gas, or nuclear?  That is the context that matters.

The international space station has been working on solar power for 23 years.  It's -454.8°F in space.  Solar energy works on rays, not warmth.

Yes, but its wet season and with some of the heavy clouds and rain we get at this  time  of year the panels won't be working anywhere near their  maximum efficiency.

A step in the right direction .

The average lifespan of a solar panel is about 25 yrs . After that it just does not deliver it's full capacity anymore .

Thailand does quite well lately concerning renewables .

If the electricity generated by solar is , at least , partly used to produce hydrogen for fuel cell powered cars , the dependency on oil can be reduced . That is good news , but needs to be done now .

Every little step in the right direction helps , as it can serve as an example for others to copy it , once they have realized that it is not difficult to do .

We do not yet fully know..... all the fuss wrt wind turbines some years ago was hype. Low generation, weather dependent and short lifespan, tied to being environmentally damaging. Many of these new sources are inactive at night or are weather dependent, and hence would obligate massive power storage installations or a need to be backed up by conventional generation like Natural Gas turbines anyhow. 

We made mistakes turning our backs on nuclear... France appears to have succeeded even selling power to UK. 

 

I see the subject of this topic as a useful experiment, and likely not a solution.

Don't worry , nuclear energy is rising like a phoenix from the ashes now . It's environmental costs are considered not as high as the costs related to the use of fossil fuels .

Next thing to come is cold fusion ...

Maybe that's true for environmental costs, but what about its cost costs?

Yes , it is expensive .

And conversion rate is still 2:1 only .

But the costs are improving ...

Hydrogen is highly volatile so storage is difficult .

But new storage technology is coming soon .

If you consider the environmental costs related to the burning of fossil fuels , it is still cheap .

 

And from the link you gave :

" Hydrogen applications which require minimal additional steps (e.g., conversion, storage, transportation, etc.) to reach the end user will most likely achieve cost competitiveness sooner than those that require greater site or application-specific investments. "

Kennedy Space Center in Florida is preparing to build the world's largest liquid hydrogen storage tank. It will involve new technologies developed by researchers at the spaceport's Cryogenics Test Laboratory.

The innovation is like going from an ice box to a modern refrigerator. "
