Abstract: Stand-alone, interactive modular solar-energy-production system. This system consists of an oblong frame that supports the photovoltaic field that receives the solar energy, an azimuth/zenith tracker, an actuating means generator and computerized control means. The base of the frame is supported in a rotary fashion on a shaft fixed securely in the ground and is supported by rolling means that can move in a rotary fashion over the ground with respect to said fixed shaft. During rotation, the rolling means adapt to the ground via tilting means associated with the fixed shaft that enable the frame to maintain balance. The base is coupled to said fixed shaft in an off-centre position and the rolling means, also, are off-centre with respect to said fixed shaft, which enables the frame to be oriented with respect to the wind in the manner of a wind vane.
