Solar panels have reduced carbon emissions, eliminated the need for expensive diesel fuel, as well as the hassle of transporting it to the countryside - often over rough roads. The initial investment in solar panels is recouped in a short amount of time and has resulted in a drastic reduction in water consumption.
