Maxwell Technologies, Soitec Join Forces

Soitec's new 5th-generation Concentrix CPV systems incorporate modules,
. . . with a 30% market-leading module efficiency
. . . (or 2X-3X the efficiency of conventional PV technology).
CPV technology converts sunlight directly into clean electricity
. . . via concentrator optics and high-efficiency solar cells,
. . . it delivers environmentally friendly, low-cost, reliable solar-generated electricity. Additionally, the CPV system's 2-axis tracker allows a high and
. . . constant power production throughout daylight hours.

Ultracapacitors are energy storage devices that charge rapidly
. . . from any electrical energy source and
. . . discharge their stored energy on demand.
In combination with a photovoltaic system, their function will be
. . . to act as a standby reservoir of electrical energy
. . . to mitigate the variability of solar energy generation.

Unlike batteries, which produce and store energy
. . . by means of a chemical reaction,
. . . Maxwell's ultracapacitor products store energy in an electric field.
. . . This electrostatic energy storage mechanism
. . . enables ultracapacitors to charge and discharge in as little as
. . . . . . fractions of a second,
. . . . . . perform consistently over a broad temperature range (-40 to +65C), and
. . . . . . operate reliably for up to one million or more charge/discharge cycles.
These Systems will also utilize forecasting, and predictive energy control.
