"It’s hard to argue against solar energy. Where most conventional
energy sources cause pollution, deplete natural resources or contribute
to global warming, solar power offers a clean, renewable alternative.
The process is silent and self-contained, with no moving parts, no
emissions and sunlight as a renewable infinite energy source. It is a
free resource after capital cost of installation. Most solar panels are
warranted for 20 years or more and require little maintenance so it's
ideal in places that are hard to get to."
