NOVELTY - The system has an electric circuit comparing a portion of an electrical signal having distortion in a power line to a desired reference signal to form a corrective signal. An electric circuit selectively sinks and sources current from a DC rectifier and a solar panel to the electrical signal having distortion according to the corrective signal to correct the distortion. The electric circuit selectively injects an additive current from the solar panel into a load or a power grid. A processor (107) switches between the DC rectifier and the solar panel for sinking and sourcing current.    USE - System for reducing distortion e.g. harmonic distortion, noise, elevated spectral noise, and amplitude modulation, in an electrical signal (all claimed) delivered to a load.    ADVANTAGE - The system allows for increasing efficiency and quality of power delivery over a power network to a load. The system can correct distortion caused by all non linear loads in a residence at one point, thus improving the quality of the power. The system is energy efficient as it improves distortion and power factor (PF) as necessary without increasing PF or distortion and without the addition of any other electrical load within a property network.
