Are there ways to upgrade old energy sources like dams and old solar panels, to make them as energy-efficient as newer designs?

    Efficiency of the solar panels depends mainly on the way individual photovoltaic cells are manufactured and from what material. Changing the whole panel would make more sense than trying to replace separate cells, especially since with increased efficiency the rest of the system would need to be upgraded to allow for higher electrical output.
    Dams, on the other hand, are frequently upgraded by adding or replacing turbines.
