Traditional solar power is manufactured by converting sunlight into electricity. Mr. Muhs told the Chattanooga Engineers Club on Monday that hybrid solar lighting is powered by collecting sunlight and routing it through optical fibers into buildings where it is combined with electric light in hybrid light fixtures. Sensors keep the room at a steady lighting level by adjusting the electric lights based on the sunlight available.
“Because hybrid solar lighting pipes sunlight directly to the light fixture and no energy conversions are necessary, the process is much more efficient,” he said.
