Frequently Asked Questions
How much light will I get?
The light intensity under a Parans L1 luminaire with 10 meters of Parans Optical Cable is around 2 000 lux, depending on how strong the sunlight is. This can be compared to the light level of window displays and studios. A common desktop lighting is around 500 lux. Check out the Parans Solar Panel section.

How many Parans SP2:s do I need for my project?
The answer is totally depending on the purpose of the installation, how the sunlight is used and what the room the be illuminated looks like. As a guideline, one Parans Solar Panel gives a good natural light experience in rooms of 10-30 m2 but then again, it all depends on the purpose of the installation. Since fiber optic solar lighting design is indeed a new field, Parans, is more than happy to assist you in designing the lighting for a project!

Where can I buy Parans’ products?
Parans solar lighting is sold through a network of Authorized Dealers world wide. To get in contact with a dealer, please email info@parans.com

Can I become a dealer for Parans solar lighting?
Right now we are searching for dealers in Germany, France, USA and Brazil.
If you are interested, please email info@parans.com

Can I install Parans solar lighting myself?
The installation of Parans system is comparable to the installation of for example a satellite dish system. The mounting of Parans Solar Panels on roofs or facades and apertures in buildings shall be done professionally. 

Will I get a tan under a Parans Luminaire?
No, the UV-radiation that creates a tan is blocked by the Parans System (and so is IR-radiation). UV-radiation is also harmful to tissues and textiles. Thus, museums love this product since it enables them to show art in natural light (just as classical pieces of art were created in.)

What is the lifetime and warranty for the product?
Parans products come with a 2-year limited manufacturer’s warranty. All materials and components are designed for a life span of 30 years.
 
Is it possible to store sunlight?
No, sunlight is instant and with exceptions for the scientific achievement of storing light in a Bose-Einstein element 1 ms, is not storable.

Is it really sunlight that comes out of the fibers?
It is indeed the same sunlight that shines on the Parans Solar Panels that is emitted through the Parans Luminaires. Therefore, variations in colour and intensity of the sunlight will instantly be transferred into the indoor environment.

Can I turn the off the light?
Yes, as an additional feature a switch can be connected to the system. This feature is valuable in many situations, for example when you have an on-screen presentation.

What maintenance requires the Parans SP2?
Just as an ordinary window needs to be cleaned, so does the glass on the solar panel. We recommend the glass to be cleaned one to three times per year depending on how dirty the local envronment is.

What happens when cloudy - and at night?
Parans aims at establishing a connection to the outdoor environment. Having the sun as the light source, the Parans Solar Panels do not transfer light when clouds block the sun. This dynamic is one key element of natural light. At night and at other times when there is no sun the Hybrid versions offer complete light solutions.

How does the investment compare to other technologies for natural lighting?
Already the initial investment is often lower than for competing solutions for natural illumination, such as light shafts and atriums. Furthermore, Parans solar lighting has a competitive advantage in that the light transport does not occupy a building’s valuable space. This generates the large economical advantage of being able to use a building’s space more efficiently. Especially since the rent and building cost per square foot rises faster than many other costs in society.
 
How many hours of sunlight will a Parans Solar Panel capture?
Parans SP2.1 collects when facing the sun within an angel of 120 degrees. The number of captured sunlight hours varies depending on geographical situation (latitude) and desired orientation (east, south, west or north) and time of the year. In most situations the performance allows for 8 hours of sunlight to be collected with one Parans Solar Panel.

For which projects can the Parans solar lighting be used?
Parans solar lighting can be installed as easily in existing buildings as in buildings under construction. There are only two factors that are crucial:
1: The location where the Parans Solar Panel is to be mounted must be exposed to sunshine.
2: The resulting length of the Parans Optical Cable must not exceed 20 meters.

Is heat transferred into buildings?
IR-radiation that converts to heat when absorbed by an object is blocked by filters in Parans SP2. This is a great advantage compared to competing techniques for natural illumination as well as to electrical lighting that creates excess heat. This cooling stands for about 15 percent – a large part of the energy consumption in buildings.

How can Parans assist me in planning an installation?
Here at Parans our dedicated staff are open to all ideas for projects. Consulting with you over your needs and desires, our expert staff will then make a project plan. Included in the plan is everything from the design and placement of the Parans Solar Panels and Luminaires and pricing right through to details on delivery and installation. Parans’ team of highly trained architects, designers and engineers ensure the highest quality in every aspect of the installation.

At what point in the building construction process is installation advisable?
This differs from case to case but most often, the actual installation is done around the time of preparing interiors and installing electrical lighting.

Do the Parans Solar Panels require electricity?
The Parans Solar Panel consumes on average less than 2 W, which is a minimal amount of power. The electricity cost per year is less than 1 Euro (based on average European electricity costs).
