A system and method for collecting renewable energy includes a solar panel and a down-sun wind turbine that are mounted on a same crossbeam. In this combination, as the crossbeam is rotated on a support pole, the solar panel is simultaneously rotated through a directional arc θ and an inclination arc Φ in accordance with a predetermined daily schedule that is based on the time of day and the latitude of the system.

A photovoltaic encapsulant system incorporates glass spheres within a polymer matrix to address light losses, water and oxygen diffusion, and brittleness in photovoltaic modules. Glass spheres ranging from 4/1000 to 25/1000 inch in diameter create refractive index interfaces that redirect reflected light back toward photovoltaic cells for additional energy conversion while establishing tortuous diffusion pathways that impede infiltration of degrading agents. The encapsulant exhibits light absorption of 6% or less compared to 10-11% for conventional glass fiber composites. The flexible system eliminates brittle glass top sheets, reducing the 5-10% failure rate from cracking during manufacturing and installation while providing enhanced optical efficiency and extended operational lifetime.
