Solar Lighting For Consumers

The University of Virginia's Solar Decathlon House shows excellent use of direct solar lighting.

Hybrid Solar Lighting promises numerous benefits to consumers. Initially targeting large commercial audiences, the HSL technology could eventually be viable for home use. The HSL technology will drastically reduce system cost and the cost per lumen generated as the table below illustrates. The economic benefits will be extended as worker productivity increases and health improves from working in and environment that has sufficient full spectrum sunlight.

The table compares the projected cost and performance of the proposed system with that of a state-of-the-art commercial system. The anticipated cost per delivered lumen of the proposed system far is much less than that of its only commercial counterpart.


Cost and performance comparison between hybrid solar concentrator and commercial system applied to both applications.
