works on both sides of the equation. Solar and wind generators are made
more effi cient by the use of thin fi lms to reach grid parity. Thin fi lm batteries
use new materials created using nanotechnology to achieve components
that are used to manufacture batteries 40 times more effi cient than
current batteries. The Solaris with its Multi source capability is the ideal
