An automatically re-configurable solar array apparatus is disclosed. The apparatus includes a solar array electrically connected to an inverter through a power switch controlled by a microprocessor. The solar array comprises a combination of solar panel strings wired in parallel. Each solar panel string comprises a plurality of solar panels wired in series. An output electrical parameter level of the combination of solar panel strings is capable of producing output power from the inverter. The output electrical parameter level of the combination of solar panel strings is equal to about a predetermined electrical parameter level under sunny conditions. The solar array is pre-wired to permit microprocessor-controlled switching to reconfigure the array into solar panel strings of varying lengths. The electrical parameter level is at least one of a voltage level, a current level, and a power level.
