Yes it does make a difference.
To see what difference it can make , a friend of mine took the photo below of his solar Panel that is mounted on his River Boat here in the Riverland.
In the first picture you see the output of the Solar Panel and in the second you see a clear increase in output once the Panel was cleaned .
Why not use the sun’s energy to produce power .
In South Australia we have a lot of sunny days and the Riverland is no exception.
That is why my friend installed this small solar panel on his Riverboat .
Many in the Riverland have taken the initiative and installed a Solar Panel System on their house or Shed roofs to do their part in the solar power industry
