In Muscat oman we are planning to implement a mw scale solar project in our college campus for own power usage.what are the approval proceedures required.

Typically the power company must ok the use and inspect the connection.  
The College Electrician (a Master if available) should
monitor and inspect while any connection to the local service.

The space for the array pointing to the direct direction and angle so
the plane of the array is positioned for maximum power.  Sometimes on  
roof tops and sometimes on the ground.  Both require planning and some  
security.  The roof must be able to hold tons of 'glass'.  A MW is  
likely going to be on the ground without trees to the east or west for
maximum time - Sun rises over houses/trees keep the array from working
until over them.  If a distance - good.

Installation on the ground (Like I have) use steel pipe (or the like)  
down in the ground with cement.  Then these are linked by pipe to create
a strong frame.  A rail system (typically Al) is placed over the pipe
and locked down.  The array panels are locked down to the rails on both
sides and they to them selves for spacing.  Wiring is done under each to  
create strings of panels going to an inverter.  The inverter attaches to  
the power panel at a site.  Power used on that panel gets the power,  
others do as well as long as the power measuring meter is outside of the  
branches.

If you have a large transformer with a power meter - that is Wonderful.
Attach anywhere inside that can handle the power!  (Large building or  
such).  This needs to be sorted out by the School(electric service) and
the utility and the solar array (or yourselves) and the information
on where the array is and where the connection is is well known.  This
might be a long set of power lines - underground or flying in the air.


Airplanes spew out oils during takeoffs and some landings.  Keeping the
array clean is important.  May not be a problem for you.

Washing might need to be done - rare but if there is soot or oil in the  
air it might collect and it is ok to 'window wash' like hotels.  Best  
done when the glass is cool.  Use soap to allow flow so it dries fast.

Remember the array works only with sunshine.  Moon and stars might bring  
some in but not much.  Use the power during the day and buy power
at night.  If the college campus doesn't use 1MW and you generate more  
than that, will the power company pay you for generating power ?  Mine  
does.  It is a clean power source.  It might not.  Something to  
determine.  My meter runs backwards when I supply and forwards when I  
use at night.

Keep us posted and feel free to ask and such.  Well done Jacob.

panels on ground usually require a high fence around them. for safety. a aquitance did some panel install work for awhile

 I've never seen high fences around them.  I suspect it is for Theft.

the person who told me about the fence requirement has a license to install solar panels
