The functionality is similar to that of Father Himalaya's solar oven, which has been known for over 120 years.

To simplify the design and reduce the material intensity of the optical connections in conventional solar ovens, the outer sections of the rings were removed, retaining only the central segments. These segments are interconnected using a lightweight wire frame, while the reflectors are fitted with thin mirror foils. This innovative approach results in an exceptionally ultra-light, cost-effective, and multifocal optical system.

For example, a 7 x 7 meter bifocal optic using this method would weigh only 160 kilograms, whereas conventional ring concentrators typically weigh several tons.

The bifocal optic

Performance Comparison: Bifocal Optic vs. PV Modules (Same Area)

The bifocal optic demonstrates a significant performance advantage over conventional photovoltaic (PV) modules. With a total aperture area of 47.3 m², the bifocal optic generates an impressive 44 kWp, compared to just 10 kWp produced by PV panels of the same size.

This remarkable efficiency is achieved through its innovative design, which optimally concentrates sunlight to maximize energy output.

Key Highlights:

• Bifocal Optic Performance: 44 kWp
• PV Module Performance: 10 kWp
• Area Compared: 47.3 m²
• Efficiency Gain: Over 4x the power output of PV panels.

This performance comparison underscores the bifocal optic’s potential to revolutionize solar energy applications, especially in regions where maximizing energy yield from limited space is critical.

This high-performance solar power plant with 5 collectors of a new type optics is specially developed for desert areas. The glass surfaces are cleaned several times a day with compressed air. Therefore, there will be no losses due to dusting of the mirrors. Operating and maintenance costs are kept to a minimum.

These collectors can be equipped with both thermal absorbers and high-performance solar cells. When required, the usable heat or electricity is generated.

The entire system is equipped with biaxial tracking to the sun.
