A RADICALLY NEW DESIGN
Insolight’s photovoltaic modules relies on a unique patented technology called planar optical micro-tracking. Embedded under the cover glass, an optical layer funnels concentrated light beams directly onto an array of high efficiency solar cells. The integrated tracking system keeps each cell in focus regardless of the Sun’s position.

The resulting flat panel combines very high efficiency with ease of mounting on any standard rooftop or ground-mounted installation.
RECORD EFFICIENCY
The technology allows unprecedented results for a flat solar panel, with 30% efficiency for sun-to-electricity conversion (300Wp/m2 ) – while mainstream modules achieve 18% on average.

Efficiency is key for the return-on-investment, as it allows a better payback of the solar installation.
BEST VALUE FOR MONEY
Since the solar light input is optically boosted, Insolight’s modules can reach an optimum efficiency with only 0.5% of the surface covered by solar cells. This approach dramatically decreases the cost of space grade photovoltaics and enables its use in a consumer product.
- 40 % more earnings for solar developers and savings for the prosumers on rooftops
- Up to 160% more energy per m2 for agrivoltaic installations, in addition to increased agricultural yields
EASE OF MOUNTING
The technology is conceived from the ground up with simplicity in mind. Sun tracking is achieved thanks to subtle integrated horizontal sliding movements, without movement of the module.

Insolight’s modules can be easily set up in any environment – including rooftops, where the need for high efficiency is the strongest.
RELIABILITY AND DURABILITY
The key components of the technology have already been extensively qualified in highly-demanding applications. The optical layer is made from a polymer known for its durability and resilience to UV light exposure, while the space-grade photovoltaic cells endure extreme conditions of radiation and temperature in satellite applications.

Reliability was confirmed by several pilot installations in Europe, with modules installed outdoor for more than a year without degradation, successfully enduring winter conditions, heat waves and storms.
IMMUNITY TO PARTIAL SHADING
THEIA modules are less sensitive to shading than conventional PV panels, thus allowing higher Ground Cover Ratios. A shade covering a horizontal portion of the module will impact energy production proportionally to the shaded area. A shade covering a vertical portion of the module will impact energy production in increments of 1/6th of total production.
TYPES OF SHADING

HORIZONTAL SHADING

VERTICAL SHADING

SMART TRANSLUCENCY
In addition to producing electricity, THEIA modules allow for dynamic regulation of the transmitted sunlight. The module can be instantaneously switched between an Electricity generation mode (E-mode) where only diffuse sunlight is transmitted, to a Maximum Light Transmission mode (MLT-mode) in which all light is transmitted but no energy is produced.

TWO OPERATING MODES

Diffuse light transmitted

No electricity produced
COMPLEMENTARY TO CURRENT TECHNOLOGIES
Insolight’s system can be assembled as an overlay on top of mainstream PV modules. This hybrid approach is especially interesting to maintain energy harvesting under cloudy conditions.

The technology involves a few module-level assembly steps, which can be added at the end of existing production lines, taking leverage of production capacities already in place. No complex cleanroom processes are required.
