Solar power is relatively pollution free.

no maintenance after initial solar power installation Systems can operate with little maintenance or intervention after initial setup.

   Solar power is becoming more and more economical as costs associated
   with production decreases, the technology becomes more effective in
   energy conversion, and the costs of other energy source alternatives
   increase.

solar power a viable energy resource    The US has begun investigating solar power as a viable energy resource
