Solar panels are marketed by the number of maximum watts they can generate.  Solar panels are sold with a data sheet or sticker on each panel to list the number of (V) volts and (A) amperes they output.   Multiply the V times the A will confirm the watts the panel can generate.  Of course 100 watts is the maximum generated by the panel in perfect conditions.  Clouds, rain and shading will immediately alter the performance of the panel. 

A 100 watt panel my generate 18.18 V's at 5.52 A's.  Wiring four 100 watt panels together would create a 400 watt array.

There are two wiring scheme to create the array.  They can be wired in a series configuration or in a parallel configuration.   Wiring solar panels in a series configuration will combine the volts each panel is generating at the same rate of amps.  In the example (4x18.18) x 5.52 is producing 400 watts.  Wiring solar panels in a parallel configuration will combine the amperes each panel is generating at the same rate of volts.  In the example (4x5.52) x 18.18 is producing again 400 watts.

Solar panels do not work by themselves.  The volts and amps they create must be passed to a solar charge controller.  This device processes the incoming volts and boost the outgoing amps, sent to the battery.  The solar charge controller will have its limitation displayed on the unit.  100 / 40 is 100 volts in, from the solar array and 40 amps out to the batteries where the energy is stored.
