Solar Bankers' Holographic Film

Solar Bankers’ core technology is a high-tech nano-structured film that manages the light in a smart and innovative way to efficiently convert sunlight into electricity, improve the thermal insulation of buildings and vehicles, and much more. The device, patented by Solar Bankers, is a micrometric-thick polymeric layer that can concentrate, bend and filter the different colors of light. The film is made of a highly transparent and durable thermoplastic, and is printed on glasses.

High transparency

Solar Bankers’ films transmit 97.5% of the visible light and are therefore fully transparent to the human eye.

Long Durability

Solar Bankers’ films have a tested durability of over 25 years.

Low Cost

The cost of Solar Bankers’ film is a fraction of that of standard concentrators. It can be printed at very large scale, similar to a newspaper, thanks to an innovative roll-to-roll manufacturing process.

Tested and Certified

Solar Bankers’ films are tested and certified by the Fraunhofer Institute in Germany.

Introducing DPV, the first Holographic Concentrating Solar Module

Smart, Elegant and Efficient


Solar Bankers’ Holographic Module, also referred to as Deflecting Photovoltaic (DPV), is a solar panel designed for high temperature environments that enables higher performance at a lower cost when compared with standard solar modules. 

30% more efficient

Solar Bankers’ module is up to 30% more efficient than standard panels at high temperatures.

50% less expensive

Solar Bankers’ DPV module uses only 25% of the silicon used in standard panels (silicon is the most expensive components in solar modules).

+25 years

Solar Bankers’ module is tested by the Fraunhofer Institute and has a proven durability of over 25 years

Self-Cleaning Surface

Solar Bankers’ module implements a highly hydrophobic film that renders its front surface self-cleaning and thus significantly reduces dust/sand deposition, which usually incurs high maintenance costs. 

The Umbrella: a Concentrator for Existing Modules

Solar Bankers’ Concentrator is intended for use in combination with standard modules to improve their efficiency and achieve greater energy output. The Concentrating Film, referred to by the name ‘Umbrella’, applies the efficiency-maximising technology used in the Holographic Solar Module to existing installations. 

300% power boost

Solar Bankers’ Umbrella increases the power output of your modules by up to 300%.

Low Temperature = Higher Efficiency

Solar Bankers’ Umbrella reflects the infrared light (i.e. heat) and transmits only those colours suitable for PV conversion. The result is an increase in efficiency of up to 30% due to lower operative temperature.

High Durability

The Umbrella has a tested durability compatible with that of standard solar panels.

Self-Cleaning Surface

Solar Bankers’ Umbrella implements a highly hydrophobic film that makes its front surface self-cleaning and significantly reduces dust/sand deposition, thus substantially lowering the costs of frequent surface cleaning.

Self-Cleaning and Insulating Film

Solar Bankers’ Self-Cleaning and Insulating Film is a fully transparent nano-structured coating that reflects the heat contained in the incoming light and keeps surfaces clean. The film is made of two layers stacked upon each other: the bottom is an optical filter, which reflects the heat-carrying portion of the light, while the top is a highly hydrophobic surface, which substantially reduces water and dust accumulation. 

30% savings on electricity bill

Solar Bankers’ Self-Cleaning and Heat-Shielding Film cools down your house and guarantees up to 30% savings on electricity bill.

50% cost savings on cleaning

Solar Bankers’ film prevents dust and sand from sticking on your windows, thus lowering the amount of time and water needed to keep surfaces clean.

Long Durability

Solar Bankers’ film has a durability of over 20 years. 

Energy Generating Solar Tile

Solar Bankers Tile is a building component that generates electricity out of sunlight. Similar to our solar module, it consists of a 3-cm thick aluminum box that integrates Solar Bankers’ holographic film and silicon stripes. The tile is mounted on rotating tubes, which follow the apparent motion of the sun to generate electricity throughout the whole day. Solar Bankers tiles can be installed both in vertical and horizontal configurations.

Elegant and Efficient

Solar Bankers’ Tile is an elegant solution for exterior building design which generates electricity with extraordinary efficiencies of up to 20%.

30% more energy than fixed tiles

Solar Bankers’ Tiles follow the apparent motion of the sun and therefore generate more electricity than fixed solar tiles.

Modular and Practical

Solar Bankers’ Tile can be adapted to any building size as there is no limit to the number of tiles that can be connected in series.

Less Costly

Solar Bankers’ Tiles are less costly than standard solar tiles as they use only a portion of the silicon (silicon is the most expensive component in solar tiles).

Energy Generating Solar Window

Solar Bankers’ Window is a fully transparent window that generates electricity out of sunlight. Solar Bankers’ nano-structured film covers the surface of the window, re-directing a part of the incoming light onto solar cells integrated in the window’s frame for electricity production.

Reduced energy costs

Solar Bankers’ Window generates energy and brings up to 30% savings on electricity bill.

Efficiency & Elegance

Solar Bankers’ Window is an elegant solution for exterior building design and generates electricity in an efficient way.

Low Cost

The cost of Solar Bankers’ Window is comparable to that of standard windows.

Light Recycling Module

Solar Bankers’ Light Recycling Module recycles artificial light and converts it back into electricity, enabling savings of up to 15% on your electricity bill. The device uses Solar Bankers’ holographic film to redirect a part of the light emitted by fluorescent lamps back onto solar cell mounted under the light source to generate additional electricity.

15 % savings on electricity bill

Solar Bankers’ Light Recycling Module is an elegant solution for interior design and generates electricity in an efficient way, with efficiencies up to 15%.

Modular and practical


Solar Bankers’ Light Recycling Module can be adapted to any lamp, regardless of its size.

Long durability


Solar Bankers’ Light Recycling Module has a durability of over 20 years.
