The sun casts its light on your solar panels, which is absorbed by semiconductor layers within the solar or photovoltaic (PV) cells. This absorption of light energy stimulates the movement of electrons, leading to the generation of an electric current, also known as DC. The inverter captures this DC, processes it through a transformer and
The answer is yes, artificial lights such as incandescent bulbs can be used to charge solar cells, provided the light is strong enough. But it will not be nearly as efficient as charging the cell in direct sunlight.

Solar cells are at the center of turning sunlight into power. These cells use the endless sunshine to create energy.

1.2.1. Working Principle A solar cell is an optoelectronic device. It can convert light directly into electricity (Fig. 1.2). Light shining on a solar cell produces both electric current and bias voltage that generate electric power. This process requires, first, the generation of electron and hole carriers by the absorption of incident photons.
Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.

Solar cells are able to convert roughly half of the infrared light they absorb into energy, and a portion of the ultraviolet light (but not much of it, making UV lights some the least efficient lights to charge a solar light with).
Provided that the artificial light in question emits the same kinds of wavelengths of light present in sunlight, the solar cell will be capable of collecting electricity from that light in exactly the same way it would in direct sunlight.
