Electricity from solar panels on your roof is in the range of 16-23% efficient, but there are no distribution losses. Electricity from a coal plant or single-cycle natural gas plant is ~30-40% efficient, and a combined-cycle natural gas plant can reach up to 60% efficiency under ideal conditions, with an additional 5% of produced electricity lost in distribution.
