Holographic Solar Panels

Views: 127
Solar Bankers uses concentrator technology that concentrates the light,
. . . which reduces the amount of silicon by over 90% and
. . . simultaneously raises efficiency.
The light is concentrated using an extremely efficient nanostructured diffractive lens,
. . . with the cell and the lens positioned closely together.
The lens is placed in front of the cells
. . . causing less silicon to be required for the same module area.
This smaller area of active silicon provides a similar,
. . . if not better output per module.
Light is concentrated on a smaller spot and
. . . targets specific spectral ranges.
The lens does not affect ranges that are not needed,
. . . such as the infrared spectrum.
Compared to the commonly used refractive Fresnel lens,
. . . Solar Bankers' holographic diffractive lens has greater efficiency,
. . . the ability to select wavelengths, and
. . . shorter distance between the lens and active area.

Solar modules within the market require an inverter
. . . to adjust the current to the voltage (MPPT: maximum power point tracking),
. . . to raise the voltage to the target of 800 volts, and
. . . to convert direct current to alternating current.
Typically, a central inverter is connected downstream of a series of modules
. . . requiring a large amount of cabling.
Inverters are prone to failure and require a lot of maintenance.

In the Solar Bankers module, the key functions of the inverter
. . . are integrated into the module's circuit.
. . . This is a substantial reduction in the amount of cabling and
. . . minimizes transmission losses.
Integrating the electronic circuit into the modules
. . . makes it possible to detect differences in output from individual modules and
. . . repairs seamlessly.

Solar Bankers plans 300 MW production of its new concentrated solar module
