In almost all regions of the world.

Autonomy

The Oktosol enables the possibility of fully self-sufficient supply for living spaces.

Dual Benefit

Land use is preserved – energy generation is added as an additional benefit.

Sustainability

Self-protection and maintenance-friendly design enable long-term operation.

Cost/Benefit

The payback period of the Oktosol ranges from 2 to 6 years, depending on the installation location.

A Vision Becomes Reality

Universal Application

Direct Connections

The collectors generate saturated steam in a temperature range from 120°C to 235°C, which can be very precisely regulated. This makes it possible to feed steam lines for industrial production processes. In doing so, fossil fuels are substituted according to the availability of solar energy.

Connections to Peripheral Systems

A key area of industrial application is electricity generation, and thus hydrogen production as well. Supplying the electrolysis station with saturated steam from the collector system further increases efficiency. In addition to pure electricity generation, there are interesting combination options that make use of heat extraction. For example, seawater desalination plants, absorption refrigeration systems, or district heating networks can be operated solely with the “waste heat” (100°C–165°C) from the power generation process.

With latent heat storage in the low-temperature range (around 100°C), it is possible to produce electricity even during periods without solar energy - contributing up to one-third of total electricity production.

Notes on Cooling Generation

Absorption cooling systems are entirely heat-driven, eliminating the need for compressors. These systems also support heat pump operation, enabling simultaneous heating and cooling. Compared to the conventional approach of generating electricity to power compression systems, absorption systems are both more efficient and cost-effective.

Notes on Electricity Generation

Modern steam engines achieve about 30% efficiency in a two- or three-stage process (with a temperature drop of about 195°C). Given a collector efficiency of 80%, this results in an overall efficiency of 24%.

Installation Possibilities

The Oktosol features a unique opening and closing mechanism that allows the mirrors to automatically close tightly and form a secure, weatherproof seal. As a result, this design enables deployment in regions with the harshest weather conditions, including deserts, high mountains, and tropical environments.
Electrical and hydraulic lines are securely routed inside the support structures.
The control unit and hydraulic transitions are completely sealed, ensuring maximum durability.
The system is resistant to environmental challenges such as sandstorms, snow, hail, extreme heat, and severe cold, maintaining reliable operation even under the most extreme conditions.

Regions

Vacuum technology and seamless insulation ensure that the pipelines remain warm with minimal energy consumption. This prevents freezing, even in the coldest regions of the world.

A groundbreaking feature is the automatic cleaning system, which is crucial in regions with high levels of dirt and dust.

In the event of severe storms, such as typhoons or tornadoes, the mirrors of the collector systems can be quickly and easily removed with just a few steps, ensuring their safety and longevity.

Autonomy

Independence in the supply of water, heat, and electricity enables the creation of fully self-sufficient living spaces. The heat generated by a single Oktosol unit can be utilized in a heat-driven distillation process, producing up to 5 m³ of distilled water per day.

Example

Self-sufficient systems also support large-scale food production. Using heat, cooling, and water, agricultural facilities can be operated on a megascale. These production hubs, or "oases," are designed to thrive in inhospitable coastal regions near densely populated urban areas, transforming barren land into productive spaces.

Dual Benefit

Agriculture presents an exciting business opportunity in large-scale electricity production. Beyond self-consumption or feeding power into the grid, farmers could establish hydrogen refueling stations or battery charging points. The viability of these options will depend on the future trajectory of automotive mobility. In this case, investing in large power grids would not be necessary.

The shade provided by the collectors often offers an additional benefit to agriculture by reducing soil dehydration and creating a more favorable environment for plants and animals. This dual-purpose approach enhances both energy generation and agricultural sustainability.

Sustainability

Production
The manufacturing process avoids the use of rare earth materials, resulting in a cost-effective product with a long lifespan, simple recyclability, and minimal maintenance requirements.

Energy Payback Period
The energy required for the production and transportation of an Oktosol is recovered within 2 to 6 months, depending on the installation location.

Low Transportation Effort
Transportation is optimized for efficiency. A single truckload can deliver 10 Oktosol units, ready for assembly, with a combined peak thermal output of 300 kW. The mirrors are designed to be stacked compactly, minimizing space requirements during transport.

Cost/Benefit

Depending on the region, an Oktosol generates between 30 and 90 MWh of thermal energy annually. At an average of 60 MWh per year and an assumed lifespan of 20 years, the cost of high-temperature thermal energy is approximately €10 per MWh (equivalent to 1 cent/kWh-TH). By utilizing the process steam solely for power generation (via Steam engine, turbine), large-scale production achives a cost of 4 Cent/kWh-EL.

Clarification:
A 20-year lifespan is a conservative estimate, as after 20 years, the system retains at least 50% of its value. By reinvesting this residual value in timely maintenance and the replacement of certain components, the system can effectively be restored to a near-new condition, ensuring continued performance well beyond 20 years.

Together, let's unlock the limitless power of the sun
