The Parans Solar Panels are 1 m2 modules that are mounted fixed on
roofs or facades. Inside the panel, 64 Fresnel lenses move uniformly
around their axis, tracking and concentrating sunlight. This
concentration of sunlight is Parans’ solution to bringing sunlight so
far into buildings in such an easy and flexible way. The technology is
patented.
Tracking the Sun
The
Parans SP2 employs an active tracking, guiding the Fresnel lenses so
that they are always orientated towards the sun. This movement is
achieved with three motors, consuming on average under 2 W. Thanks to
the active tracking, the Parans SP2 can be installed or moved to any
location and orientation without pre-programming. On a technical level,
the tracking is controlled by a photosensor that continually feeds the
internal microcomputer with light level data. At installation, the SP2
immediately scans the sky to detect the direction to the sun. It then
learns and remembers the solar path so that it always is ready to
collect sunlight.
Concentrating Sunlight
The
tracking keeps the surface of the Fresnel lenses perpendicular to the
direction of the incoming sunlight throughout the day. The
configuration ensures that the sunlight is efficiently concentrated
into 0,75 mm optical fibers placed underneath each lens.
Performance
The
new Parans SP2 has the capacity of collecting sunlight over large
angles as well as delivering high luminous flux. The SP 2 can collect
sunlight with an incident angle of 60 degrees from the direction to the
sun, thus forming a 120 degrees active cone. This represents on average
8 hours of sunlight. The luminous flux output from the Parans SP2 is 14
000 lumen at a normal solar illuminance of 100 000 lux. See the
following section for luminous flux over varying lengths of the Parans
Optical Cable.
