In a readily switchable multiple solar panel system, the individual solar panels are interconnected with a control or switching apparatus which allows the solar panels to be readily switched into various series, parallel, or series-parallel configurations. With a relay based switching apparatus, a relay is connected between a pair of solar panels, so that in a first state, the panels are in series where the total voltage is the sum of each individual panel's voltage. When the relay is switched to the second state, each solar panel is in parallel, where the total voltage is a single panel's voltage and the current is multiplied by the number of panels. Multiple panels can be connected in this manner, with a relay between each successive pair of panels. With each relay connected in a parallel arrangement, a simple control switch in series with the relay coils can control the panel switching. The coil of each relay can also be individually controlled. Other individual voltage sources than solar panels can similarly be connected through a switching system which provides selective configuration of the sources into series, parallel, or series-parallel arrangements.
