Smart & Green City: Bifacial & transparent glass-glass/double-glass solar modules ideal for agri-photovoltaics, open-space systems, solar carports and solar fences

As the share of electricity from renewable energies increases, it becomes clear that AI (artificial intelligence) will have to control the energy system's processes on a large scale in the future. While power grids with central power generation have dominated so far, the trend is towards decentralized generation systems. This applies to production from renewable sources such as photovoltaic systems, solar thermal power plants, wind turbines and biogas plants. This leads to a much more complex structure, primarily in the area of ​​load control, voltage maintenance in the distribution network and maintaining network stability. In contrast to medium-sized to larger power plants, smaller, decentralized generation systems also feed directly into the lower voltage levels such as the low-voltage network or the medium-voltage network.

Suitable for:

• Building an intelligent power grid – A decentralized energy system needs AI

An intelligent power grid integrates all actors into an overall system through the interaction of generation, storage, network management and consumption. Power plants (including storage) are already controlled in such a way that the same amount of electrical energy is always produced as is consumed.

Green City and agri-photovoltaics are not just about the maximum output of the renewable energies to be used. Here we are primarily talking about solar modules, the most flexible and widespread renewable energy sources.

So no performance potential at the expense of others and the environment, but economical and environmentally appropriate adaptation such as the use of all possible components according to the principle that a lot brings a lot.

Glass-glass modules represent a technology that, in addition to their high performance efficiency, is characterized by their extreme durability and at the same time an attractive appearance, which makes them interesting for both private users and in the architectural sector such as solar fences, solar carports and also agricultural photovoltaics. Glass-glass modules are glazed on both the front and back. The additional layer of glass ensures better protection and a longer lifespan of the panels.

Although glass-glass modules are more expensive to produce than conventional solar modules, the higher production costs are offset by the much longer service life of these modules. Due to their high resistance to weather influences such as wind and moisture, glass-glass modules have a service life of 50 or more years. In contrast to the plastic films otherwise used, the glass structure does not become porous, which, in addition to longer durability, offers better protection against dirt.

• Two-surface, bifacial or bifacial solar cells – interesting information about solar modules

Another plus point is their higher efficiency. The modules deliver a comparatively high level of efficiency even in poor lighting conditions. Added to this is the greater fire resistance and remarkable stability of the glass-glass modules. There are also other practical advantages in favor of the system: Since the structure does not require a frame or a visually disturbing back film, the modules can be ideally installed in the living environment, for example as sun and privacy protection on the terrace at home. They can also help to generate electricity efficiently in the long term in carports or in larger parking lots (for example in supermarkets).

Compared to traditional roof-mounted solar panels, a vertical orientation prevents any snow accumulation. Among other things, it was found that the solar gain is increased in winter because the solar modules are aligned more towards the lower sun angle in winter. Reflective snow on the ground has also been found to increase solar energy by up to 50%.

Correct planning and selection of the appropriate solar mounting system are also important. Just as solar systems and mounting systems exist in different designs, there are also different types of facades, which not only depend on the type of building (including house, warehouse) and type of construction (including wooden house, brick building, concrete building, lightweight steel hall), but also differ in their construction.
