Sunlight is made of photons, which carry electromagnetic energy.
A Joule (J) is a unit of energy, and a Watt is an energy flow rate (1W = 1J/s).
A 1W device operates at a defined power level of 1J/s.
A 100W solar panel's photovoltaic (PV) cells absorb sunlight and convert some of the photon electromagnetic energy into electrical energy.
The panel delivers the converted electrical energy to a controller, power‑management system, or operating device at 100J/s.
PV cells are not perfect absorbers. In fact, 25% is pretty good for a budget panel.
So, if 1000J of sunlight hit a m^2 solar panel in one second, it converts about 25% of the incoming sunlight energy -- around 250J -- into electrical energy.
The other 75%? Some is reflected away from the PV cell, other converts to heat, panel operating loss, etc.
Why does the panel have a rate (i.e., 100W)? Because every part of the panel as a system -- as well as the systems or devices receiving the converted power -- has designed-in limits on how fast energy can flow.

So this panel converted 25% of the solar radiance to electricity to 100W in ideal conditions.
Nothing can reach 100% that would mean the panel looks completely black and is cold to the touch
