That light has way less than 1% of the intensity of sunlight.
Edit: from here you get that the brightness of moonlight is 0.05 - 0.3 lux whilst that of direct sunlight is 32,000–100,000 lux
Our eyes deceive us (our pupils dilate or contract and we have different more sensitive cells in our retina for seeing in low light conditions) and make it seem brighter than it actually is whilst making sunshine during the day seem less bright than it actually is.
You can use any light of the right frequencies on a solar panel to produce electricity, but the amount of current you can get on a solar panel from moonlight and starlight is minuscule.
My bet is that the 1% comes from things like molten salt solar power plants which during the day use sunlight to heat up some kind of salt (which is used to produce steam that powers a steam turbine), some of which will only be used to actually generate power during the night.
