Fortunately, solar photovoltaic doesn't need servicing. Energy is big business, revenue will be there for servicing once market share is there.

  Solar photovoltaic probably needs more servicing per kWh than any other method. If those panels aren't clean, you don't get the expected return.

      They actually already exist. Google "solar panel cleaner robot" or similar.
