While solar panels are most efficient under bright, direct light, they can still produce approximately 10-25% of their maximum solar energy output on a fully overcast cloudy day.
[pdf] Concentrating solar power plants use sensible thermal energy storage, a mature technology based on molten salts, due to the high storage efficiency (up to 99%).
[pdf] For a photovoltaic glass transmittance of 40%, the highest photovoltaic power generation efficiency is 63%, while the average efficiency is 35.3%.
[pdf] A single vertical turbine has an efficiency in the range of 35 to 40 percent (though vertical turbine researchers are sure that number will soon reach 50 as well).
