1. A method, comprising:
providing a solar array electrically connected to an inverter through a microprocessor-controlled power switch, the solar array comprising a first combination of solar panel strings wired in parallel, wherein each solar panel string comprises a plurality of solar panels wired in series, an output electrical level of the combination of solar panel strings capable of producing output power from the inverter, wherein an output electrical level of the first combination of solar panel strings is equal to a predetermined electrical parameter level under sunny conditions, and wherein the solar array is pre-wired to permit microprocessor-controlled switching to reconfigure the array into solar panel strings of varying lengths; monitoring in a microprocessor the electrical level of the first combination through an electrical level sensing circuit, the first combination of solar panel strings comprising a first combination of one or more switchable mini-groups of hard-wired solar panel strings; and when the monitored electrical level of the first combination falls below the predetermined electrical parameter level, re-configuring the solar array by microprocessor control to a second combination of solar panel strings wired in parallel, the second combination of solar panel strings comprising a second combination of the one or more switchable mini-groups of hard-wired solar panel strings, the second combination of the one or more switchable mini-groups having a configuration that combines at least a portion of the first combination of one or more switchable mini-groups of solar panel strings to raise the monitored electrical level of the second combination of solar panel strings to be equal to the predetermined electrical level under sunny conditions, wherein each solar panel string comprises a second number of solar panels wired in series, and wherein the output electrical level of the second combination of solar panel strings is capable of producing output power from the inverter. |
