Question:

Can you overload solar panels with too much light?

If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.

Answer:

A photovoltaic cell will only be 'sensitive' to a band of radiation...and would probably not even 'see' the energy from a heat lamp. So, no, the solar panel would not be 'overworked' if somehow you could put 2 or 3 suns in the sky at once. It would simply ignore, so to speak, the photons that it didn't need. But, the heat from the heat lamp, or the extra photons, would eventually heat up the glass and the plastic the thing is made of, and it would fail prematurely.
Solar panels have a upper temperature limit, and it's only a bit more than it would reach in a very bright sunny day near the equator. Start shining heat lamps on it and you will raise it past it's max temperature, and it will die. .
yeah, as you shine light over a solar panel, it begins to lose electrons to the circuit. if you shine light with enough intensity (that means not strong light, the photoelectric effect makes no distinction between a powerful photon and a weak one, as long as they're both over a certain energy, but a lot of it, as in, a lot of photons), the material may not recover electrons at the same rate it loses it, and would stop working, until you gave it a rest.
Solar panels do not wear out the way machinery does. The semiconductors used give up electrons by receiving photons, and do not experience a net deficit of particles. However, if you placed a heat source such as a heat lamp too close to a solar panel, you could damage the panel by overheating it, which would denature the semiconductors or cause damage by scorching or melting. The problem would be the heat, not the light. Solar panels do have a finite life expectancy, though it is several decades under normal circumstances. The panels will eventually become scratched, warped, and dented. The electrical conductors will eventually be broken by metal fatigue as the panels heat and cool on a daily basis. So they will die of old age, but they don't wear out in an electrochemical sense.
