hybrid solar lighting

Researchers at the Oak Ridge National Laboratory had developed a solar lighting technology employing a rooftop collector and fiber optic cable and needed assistance in evaluating the technology and commercial market. We prepared hardware production cost estimates, and created a model of lighting annual performance for selected geographic regions most suitable for solar applications. We then compared hybrid solar lighting to several potentially competing technologies.

After evaluating expected annual performance, we then estimated the expected national market for this technology and inferred the resulting air quality benefits. The Hybrid Solar Lighting System (HSL) is now available commercially. The visualization here shows how HSL might power a new family of office lighting fixtures using LED illumination when sunlight is not available.

mission

We develop and market energy efficiency strategies and technologies. We focus on the building and transportation sectors, which account for more than two thirds of the energy budget.
