The photovoltaic

The solution to obtain greater efficiency and less deterioration of solar panels



We often hear about Green Energy. But what exactly is meant by this term?

We can define green energy as any energy source that is regenerated at least at the same speed with which it is used, coming from sources that can be referred to as 'green' both for their inexhaustibility and for the relatively less impact they have on the environment. By extension, these are all those forms of energy generated by sources whose continuous use does not affect the use of the same by future generations.

Over the years we have approached this theme bringing with our know-how and the propensity to innovate.

We have developed skills and expertise to provide a customized product and after-sales service, to fully cover the customer's needs.


In the photovoltaic sector, however, there is no maintenance that can overcome the deterioration of materials.

Certain factors can compromise the capacity of a photovoltaic system to the point of making it unusable.

Solar panels are naturally exposed to atmospheric agents typical of the environment in which they are installed: dirt, dust, bird droppings, etc., can veil the surface of the panels and reduce their efficiency.


Deterioration of materials

Hail, stones, branches and debris can cause cracks on the glass surface causing a reduction in efficiency or even replacement of the panel.

The deterioration of the glass protecting the solar panels, as well as that of the solar cell leads to a reduction in efficiency.


A solar panel varies its efficiency, depending on the angle of incidence of the sun's rays that insist on the cells.



The angle of incidence for optimal efficiency is 90°, therefore the technicians adjust the inclination to reach this angle at the moment of maximum height of the sun on the horizon, around 12.00.

Furthermore, the inclination is not constant during the year as the height of the sun on the horizon varies with the seasons.

The geographical orientation and the angle of inclination (tilt) can affect the energy performance of the system.


There is no angle of inclination that offers optimal efficiency throughout the day and for all seasons.

Using the principle of optical diffraction, you can easily observe how by inserting a prism between the source and the target, the light rays are deflected by a certain degree with respect to the angle of incidence.

Furthermore, the light is divided into different frequencies; by inserting suitable filters it is possible to allow the passage of the most efficient frequencies and the blocking of the least ones.

Therefore, after extensive studies and research, it became clear that the path to achieving the goal was in

Adaptive Holographic Diffraction



Performance improvement thanks to optimal incidence and light filtering



Causes of aging of a photovoltaic panel

The main causes of aging of a photovoltaic panel are:

  • UV rays

  • Work charged to the cell

  • Strong fluctuations in inverter operation

Cause danneggiamento

The OQS film protects the panel from UV rays by rejecting them and stabilizes the work carried out by the inverters, avoiding the so-called "peaks" and reducing the production oscillation range.

The result is that OQS increases the life cycle of a photovoltaic panel

Pellicola OQS


OQS film is a self-adhesive film based on adaptive holographic diffraction.

Applied to the surface of the solar panel, the film corrects the incidence of sunlight by optimizing the angle of impact of photons on sensitive cells.

The result is an extraordinary increase in performance and protection from dirt and deterioration.
