Lime Down Solar Park , if it goes ahead will decimate some of the finest agricultural producing land in Wiltshire. It is spread over  five massive sites. Note just how much extra land will be required for the cabling.

The installation of Solar PV does not  "decimate" land as you  have said.  The land will hardly adversely  be affected.  compared to other  human activity the installation won't  have such  deep  foundations as building  a factory  or even a power station. The installation of PV does not  pollute the land like other industrial processes,  and ultimately the land can easily  be returned to completely to farming if or when the PV systems is  no longer  required. Try doing that  for almost  any  other type of building especially  where chemicals or other pollutants may have been used.
Whilst a PV array  might  restrict  arable farming,  in many  places where Solar has been installed the site can still be grazed,  in fact grazing is a great way to keep the site from being  over run by  grasses and weeds.  
The routing  of feed in cables may  be a little contentious,  but  if the area as a whole was to have its electrical supply  updated as a development  of the National Grid without the PV similar amounts of land would have been required for underground systems. As others have said in most  places where such  work is carried out the land is restored and nature quite quickly  disguises the works. The location of the cables may  need to  be protected from future developments but that  is  no  different to the situation today with  power, gas, water mains and sewers.
I can understand that  some locals may  feel the construction of a solar PV farm will spoil the visual appearance of an area, But when its operating  It  wont create  noise,  smells  or spills its Vegan  friendly,  and it  will make the UK even more independent on energy  supplies from fossil fuels,  and source from abroad. 
We have a very  idyllic view of the English landscape,  rolling  hills and hedgerows, meadows and rivers etc - even canals,  But the reality is the English countryside is almost  all been changed by  man,  and most  of the views we seek so hard to protect are not the  natural state of our landmass but  are derived from  centuries of land owners wishing  to partition and demarcate  their land ownership,  along  with farming on an industrial  scale. 
Solar  PV and wind farms are  just the next  phase of our conquering  our  habitat.
