RaffSun is designed for a 20-25 year usage period. More precise figures coming soon.

This cannot be said in general terms, as every project and every building is different depending on materials, facade accessibility and installation requirements. Our approach is to plan from the very beginning in a holistic and forward-looking manner in order to ensure that as little unnecessary work as possible is carried out and that the installation can be carried out in a time-efficient manner.

Basically RaffSun does not need to be cleaned. However, we strongly recommend this to increase the life span and to keep the power yield as high as possible. We arrange for companies that specialize in cleaning RaffSun.

RaffSun has not yet been installed. This year RaffSun will be used in a pilot project.

RaffSun has interfaces for common building automation systems and at the same time the possibility to be controlled safely and reliably via software provided by us. The intelligent control, which enables maximum power yield while taking user needs into account, can be used in all control constellations.

The modules are installed by companies commissioned by us. In this way we can guarantee that no errors occur during installation and also promise the fastest and smoothest possible installation process, so that your employees lose as little time and productivity as possible.

It is impossible to say this in general, as each project and each building is different depending on materials, facade accessibility and installation requirements. Our approach is to plan from the very beginning in a holistic and forward-looking manner to ensure that as little unnecessary work as possible is required and that the installation is efficient in terms of time.

RaffSun is cleaned using brushes and cleaners. We can arrange for companies with trained personnel to carry out a cleaning with simultaneous inspection. In this way you can always be sure that RaffSun is used to its maximum potential.

Since the RaffSun blinds retract completely into the top box, cleaning of the windows can be done without any further complications. When cleaning the windows, care should be taken to ensure that the detergents are compatible so as not to damage the encapsulation of the solar slats. We will provide a list of compatible as well as incompatible cleaners in the near future.

We can arrange for companies who are familiar with RaffSun and can already carry out an inspection during the cleaning process, so that any damage can be detected at an early stage in order to ensure the longest possible service life and high efficiency.

The power is routed from RaffSun through cables to an inverter. Depending on the design of the infrastructure, this may be several small inverters or one or a few large inverters. From there it is then possible to use the electricity processed by the inverter in the form of e.g. 230 V, 50 Hz AC (German standard) for conventional end devices.

As with conventional solar systems, it is possible to store the electricity in suitable storage devices. RaffSun can be integrated into an existing structure, or such a storage device can be installed when RaffSun is installed.

It can either be stored or fed into the public grid for a feed-in tariff. Storage of the electricity offers the highest economic efficiency.

If a single slat is broken, the slat-curtain of RaffSun can be removed and repaired using minimally invasive procedures. Since the curtain is simply hung into the frame, no complex work steps are necessary.

This requires specialist personnel trained for heights. Since the installation differs only in certain points from that of a normal external blind, the specialists trained for this purpose are also already available.

RaffSun is manufactured in Germany. We pay as much attention as we can to ensuring the lowest possible emissions and fair conditions along the entire production chain.

This must always be assessed and decided on a case-by-case basis due to different regulations and guidelines. However, we are planning to expand the market and thus soon offer you the possibility to use RaffSun as standard.
