A solar power system for a marine dock includes a telescoping vertical member affixed to a dock via a bracket. A solar panel is pivotably and rotatably affixed to the top end of the telescoping vertical support. A weatherproof equipment container is affixed to the telescoping vertical support. A meter unit, battery, and inverter are housed within the weatherproof equipment container. First leads connect the solar panel to the meter unit, which is configured to measure and display energy and/or power generated by the solar panel. Second leads are configured so that current is passed through the meter unit to the battery in a charging configuration. A third lead connects one terminal of the battery to a measurement terminal on the meter unit, which is configured to measure and display the output voltage of the battery. Fourth leads connect the battery to the inverter in a discharge configuration.
