You are correct. Solar power works under sunlight.
Most solar systems have some sort of power backup.
In remote locations that are "Off Grid" or where maintaining constant power is critical, this is often done with a bank of battery and even a diesel generator as backups.
If traditional power is available, then most opt to use their solar to augment the power from the utility company. A common term is "Net Zero". When you generate more electricity than you use the electric meter spins backwards. This happens during the day when the sun is out and no one is home. Then at night and cloudy days, the meter spins normally. So the readout spins back and forth. At the end of a period of time you get billed on the net difference. You want the net to be zero. The goal is to produce just what you use. Any less and you have to pay for electricity, any more and you are giving it away.

If the fibre optics cables could carry energy as well then Solar Energy could be distributed to Dark areas of the globe.

With a solar power system, sunlight is converted into electricity by the action of the sun’s radiation energy (photons) striking the surface of the photovoltaic cells. When more electricity is generated than is being used, the excess energy can either be stored in batteries or channelled back into the commercial power grid.
At night (or when it is rainy or overcast) when there is no direct sunlight striking the solar cells, the energy that was generated earlier and stored in batteries can now be used.
