Light guides direct collected light, concentrating it along predefined and strategically chosen paths, and then diffuse it into specific environments. By inserting photovoltaic (PV) cells along these paths, significant amounts of energy that would otherwise be wasted can be collected. Similarly, light can be directed towards the PV cells through specially designed routes. These simple adjustments allow for the creation of solar energy collectors that would otherwise be unfeasible.

The H&S electronic architecture, combined with the patented photovoltaic strip and its associated technology, enables the development of innovative components such as spherical photovoltaic panels with UPS functionality, light guides with storage capabilities, and mobile uninterruptible power supply units that are easy to transport and position.

The spherical photovoltaic panel is an example of a concentrated light energy storage system, consisting of two concentric spheres. This system captures sunlight through reflections and reverberations, storing it in a battery. The inner sphere is coated with photovoltaic cells and diffuser prisms, while the outer sphere is made up of diffusive lenses flanked by strategically positioned mirrors. This creates a fully illuminated spherical crown, where diffused light hits the photovoltaic cells, converting the light into electrical energy stored in the batteries managed by the H&S electronics.

The spheres can have different diameters and be placed anywhere, blending with the surrounding environment through color adaptations. The diameter can range from 50 cm upwards, with the most effective solution typically around 100 cm. Inside the cavity of the sphere are housed the storage battery and the management electronics. The electrical interface includes a 50-volt DC bus and a digital control connection (RF or CAN). In some applications, it is possible to integrate an inverter for the generation of alternating current compatible with national grid standards.

The system is patented and currently in the prototyping phase. Commercial availability of the first version is expected by late 2024/early 2025. Initially, three versions will be available with diameters of 50 cm, 90 cm, and 120 cm, and battery capacities of 5 kWh, 20 kWh, and 40 kWh respectively.
