Definitions

• the invention belongs to the broadest field of electricity, the subdomain of photovoltaics, and the narrowest field of optics for improving the photovoltaic response (an increase in electricity production) of solar panels and cooling of solar panels.

• optics for light manipulation that contributes to the better photovoltaic response of solar panels were not found.
• V part with flowing water and the construction of its identical parts on a large carrier, shown schematically further in Figure 1.
• a construction composed of several optical parts with flowing water on a designed carrier for large external solar panels is shown in Figure 1.
• the present invention as a supporting structure for solar panels (Figure 1) technically solves the manipulation of light or light spectra reaching the surface of solar panels at both higher and lower light intensities while indirectly cooling the surface of the solar panels.
• We can manipulate light intensities and light spectra by varying the position of the optical part through which the cooling water flows (by approaching and moving the optics away from the solar panel, as well as moving the optical part at different angles on the plane of the carrier).
• We can have either a concentration effect in which the light intensity increases or a reduced light intensity with simultaneous indirect cooling.
• a change in the light spectra that reaches the surface of the solar panel occurs.
• the water passing through the designed optics is not only used for indirect cooling of the surface of solar panels, but the optics depending on the position of solar panels lead to an increase or decrease in radiation intensity, as well as changes in spectra and thus improvement of the photovoltaic response of solar panels.

• Further patents/inventions are related to various surface-cooling systems for solar panels (1020130105130, 2609630, 1996236798). The claimed patent/invention concerning the possibility of manipulating the light spectra have not been found in the international patent database.
• the optical system for cooling, light manipulation, and photovoltaic response improvement of commercial solar panels is designed and made in a way that certain natural external changes are monitored and solve several technical problems at the same time.
• each above-mentioned problem such as cooling the surface of solar panels, increasing light intensities to improve electricity production, is considered and solved separately.
• the manipulation of light spectra to increase electricity production and at lower light intensities has so far been reported by the authors in scientific papers, while no application has been found in patent information. It should be emphasized that the designed optical system with flowing water allows combining several technical solutions into one system.

• This second direction encompasses everything needed to maintain and use solar panels in their maximum possible use, and these are surface-cooling systems for panels, optics that improve the photovoltaic response of solar panels, and an essential segment, which includes the manipulation of light intensities and light spectra to obtain a larger amount of electricity.
• Our designed optics with flow water belong to the second described direction of improving the operation of solar panels and the production of a larger amount of electricity.
• the increase in electrical efficiency is dependent on the size and type of solar panel device, as well as the season and geographical position (light intensity, light spectra reaching the surface of the solar panel, and the angle at which light falls) and increases overall efficiency and thus electricity. It is generally believed that the intensity of solar radiation and the quality of semiconductors from which the solar panel was made which directly affect efficiency are factors that we can control, while variations in solar radiation or solar spectra reaching the surface of the solar module cannot be controlled. However, any designed cooling system that includes liquid/water leads to a decrease in the intensity of the sun's rays and changes in the spectra because light passes through different environments. Thus, realistic, reduced light intensities and the impact of altered light spectra on the efficiency of commercial solar panels are a reality.
• the invention is shown in the following:
• Figure 1 shows the appearance of an optical carrier (lens system) with flowing water placed above the solar panels.
• the carrier with an optical system for cooling, light manipulation, and improving the photovoltaic response of commercial solar panels consists of a square-shaped carrier made of lightweight materials with the classic size of solar panels, or the size of panels whose efficiency wants to be increased. It is composed of several optical lenses in one row of carriers connected by pipes through which water flows. Several series containing connected optical lenses are interconnected by the carrier structure and represent the whole carrier ( Figure 1).
• the following components comprise the present invention, as shown in the figure: carrier construction 1 for solar panel, side frame 2 of the carrier construction, rotary stand 3 for optical system carrier, guides 4 for lens stand height adjustment, lens stand 5, pipes 6 connecting lens through which water passes, optical lens 7, water supply 8, and water drainage 9.
• Each of the individual optical lenses 7 (mutually identical and connected) consists of two convex (collecting) glass lenses through which cold water (whose flow can be regulated, increased, and decreased) continuously circulates. Due to its convex shape, optical lens 7 has the largest thickness of the aqueous layer in the central part.
• Each of the two interconnected convex glasses (which we call the optical lens as a whole) is completely closed and secured with frames (in terms of possible water leakage), from which on both sides of the optical lens 7 comes pipes 6 that connect the lenses and through which pass cooling water.
• the first and last optical lens 7 in a row is connected to the water supply 8 and water drainage 9, respectively.
• the number of lenses in one row, as well as the number of rows on the construction of carrier 1 depends on the size of the solar panels.
• the rotating stand 3 on which the solar panel is placed together with the entire construction of carrier 1 can move in different positions depending on the position of the Sun.
• cooling is associated with maintaining the outside temperature, given the fact that the water, which flows through the optical part is not in direct contact with the surface of the solar panel, but indirectly affects the surface temperature of the solar panel by cooling the surroundings.
• the water flow velocity can be increased, thus achieving better and more efficient cooling.
• each optical lens 7 on the presented carrier structure 1, which are interconnected can be simultaneously moved away or closer to the guides 4 of the carrier structure 1, relative to the solar panel. Also, each optical lens 7 (i.e. individual rows of connected lenses) on the carrier can be rotated (shown by the arrow in
• Figure 1 at a certain angle concerning the construction of carrier 1 for the solar panel.
• Optical systems for cooling, light manipulation, and improving the photovoltaic response of commercial solar panels can be used to improve the photovoltaic response of the most used silicone solar panels (97% of the market) as well as all other solar panels available on the market.
• the light is manipulated at both lower and high intensities of solar radiation with continuous cooling, so that the optical carrier placed on the surface of solar panels is used in both high outdoor and low outdoor radiation to increase electricity production.
