Independence through solar energy for your home or business
The conversion of sunlight into electricity, known as photovoltaics, is becoming increasingly popular. But why is this alternative energy source so popular, and how does it actually work?
Free electricity generation, permanent reduction in electricity costs, protection from rising electricity prices, a reliable supply of electrical energy over a long period of time, as well as the wide range of applications and mounting options are just some of the arguments in favor of acquiring a solar energy system.
The functioning of these systems can be traced back to the properties of the individual photovoltaic modules, which together form the systems. In 90% of all cases, these consist of rectangular silicon solar cells. Since the earth’s crust is about 28% silicon and thus virtually unlimitedly available, the development and production of these systems is also promising and secured for the future. In addition to the silicon content, a small amount of aluminum and silver is also required for the production of the modules, the latter of which can be largely replaced by copper in the foreseeable future.
In the solar cells, the basic building block of a photovoltaic system, the energy of sunlight is absorbed by the silicon and converted into electrical energy. The more intense the sunlight, the greater the amount of electricity produced by the PV system.
Current top modules have an efficiency of 20%, which indicates how much sunlight incident on photovoltaic modules is converted into electricity.
Solar energy is also a pioneer in the field of sustainability: Depending on the technology and location of current photovoltaic systems, they have already generated as much energy after about 5 to 18 months as is needed for their manufacture, operation, and disposal. The lifespan of current PV modules is on average 25 to 30 years. In addition, nowadays already 96% of the solid materials in photovoltaic modules can be recycled.
Optimized grid relief through efficient storage solutions
Our energy storage systems enable you to sustainably compensate for fluctuations in photovoltaic energy generation. The strength of solar radiation fluctuates daily and monthly. In the middle of the day, the sun shines stronger than in the evening, and in the summer it shines stronger than in the winter. However, these problems can be easily overcome by lithium-based battery storage systems, as our storage systems allow you to decouple the time of feed-in from the time of energy consumption.
It is important that the storage capacity in a renewable energy system is large enough to be able to absorb as much energy as possible at the time of the lowest energy generation in order to meet the actual energy demand.
International cooperation
In order to be able to offer our customers affordable, highly efficient, and flexible photovoltaic products, we offer you promising and innovative container solutions in the MWh range together with our partners.
Furthermore, we are diversifying our supply chains and sourcing our resources from growing markets such as South Africa in order to promote sustainable bilateral cooperation on an equal footing and to help in the development of an emerging economic region.
Photovoltaics for your car? Our charging stations make electromobility possible!
Electric cars are the vehicles of the future, but only with CO2-free electricity do they really keep their promise of more sustainability! Cars that are powered by an electric motor and a battery made of lithium-ion batteries have the great advantage that electricity can be directly refueled without having to convert it into hydrogen or synthetic fuels beforehand. This avoids the energy loss that occurs during the conversion. In addition, electric vehicles have an energy requirement that is three times lower than that of gasoline vehicles and also have fewer wear parts, which leads to significantly lower maintenance costs and intervals.
If you charge your car with your own photovoltaic system in combination with an energy storage system, you not only reduce your ecological footprint, but also lower the costs for kWh used when charging.
To illustrate these figures and information, you can look at the following example: a system in Germany with an optimal orientation and a power of 1 kWp produces about 800-1100 kWh of electrical energy per year, depending on the location. This corresponds to about a quarter of the average private electricity consumption of a four-person family in Germany, which makes solar energy a particularly economically attractive and sustainable option, especially in times of energy crisis and climate change.
