A greenhouse used as a solar panel support structure maintains the usability of the greenhouse through at least one solar panel assembly in order to produce electricity, as well as, optimize light exposure for enclosed plants. The at least one solar panel assembly includes an array and a solar tracker. The array is a photo-voltaic module to convert solar energy into electrical energy to power the greenhouse, other onsite devices, or to export excess energy to a local electrical grid. The array is positioned to receive sunlight to produce electrical energy or provide sunlight exposure to a plurality of plants positioned within the greenhouse. The solar tracker controls the position of the array to move in accordance to sun exposure during a solar day, to maximize electrical power generation, and to allow shade created by the array to move evenly within the greenhouse.
