They can but their effectiveness is reduced.
NO
Technically this process is impossible to have power on a cloudy or rainy days. This is the down side. But, with very powerful yet expensive solar panels, you may have a vauge power source with it.
If there is light- there is power
but its proportional.
so cloud cover = less energy
They can, but not as much as without clouds or fog.
It can still produce electricity, just not as much as if there were no clouds in the sky. See this link for more advantages and disadvantages of solar energy:

Photovoltaic solar panels will generate electric energy even when the clouds block the sun. However, the output will be reduced.
Solar panels make use of the sun energy,though there are alot of clouds blocking the sun,i think there should be a little sunlight reaching the solar panel too.
The efficiency is reduced…that’s why you need a heat sink or other storage system to see you through the times when the sun is not out.
You also need to have shutters on your collectors or valves that will shut off the them off otherwise the system can flow backwards and actually lose energy during cloudy days or at night.
In some areas rather then using the collected heat as is its actually more efficient to use it as a tempering or preheating system.
The majority of the energy used to produce (hot water)for example is used to bring the water from cold entry temperature to room temperature say 50-60 percent.
But if you mix your solar heated water into the water to bring it up to room temperature then you only need 40-50 percent to kick it up.
