A photovoltaic solar system is used to charge lithium ion
batteries for a grid level energy storage installation. The solar
system converts 19% of the available sunlight to electricity.
Charging of the lithium ion batteries is 95% efficient and
discharge of the batteries to the grid is 95% efficient. What is
the overall efficiency of converting available sunlight to
electricity supplied to the electric grid? Give your answer in
