LCPV drives solar panel cost to 1 EUR/Wp.

Nesher, Israel (ots) - Although externally simple in concept, low
concentration devices will require optimization of many parameters
involving optical concentration acceptance angle with and without
tracking, cost of materials and low cost fabrication methods. This
multidisciplinary task is essential for optimizing the
techno-economics for a low cost solar solution.

At SolarOr - an Israeli start-up such skills and the basic
foundation for a new technology promising low cost solar harvesting
performance within the silicon framework, i.e. offering solar
conversion efficiencies of about 15% with panel cost rivaling the
thin film technology. Based on the LCPV concept, two product lines
are in the final stage of development. The first is curtain wall with
high efficiencies (~15%) and the second is utility scale panels
offered with built in proprietary dual axis trackers. Moreover,
SolarOr's activity is supported by an Israeli solar consortium
offering improved collaboration between several key players of the
local industry.

1. SolarOr Facade Product Line

For example, SolarOr technology is implemented in a prismatic
solar curtain wall product line characterized by diamond like
aesthetic appearance. In this application a prismatic glass or
plastic elements are used to solve the daunting task of optically
concentration on one hand, and to have a relative high acceptance
angle on the other hand. By carefully optimizing and simulating the
sun movement, an array of prismatic elements each equipped with a
solar cell was developed. This array yields a concentration ratio of
2.5 times more (x 2.5) over wide range of sun movement of about 60%
(+/- 60%) in respect to its noon time position. The sun's
concentration features cuts the total silicon amount by a factor of
2.5 while keeping the curtain wall efficiency at values close to 15%.

Making the curtain wall optimized to sun trajectory, which is in
its upper hemisphere further increases the overall usefulness of the
system since it is facilitating selective light handling as follows:

- Light direct plus diffuse from the upper hemisphere is
concentrated and absorbed by solar cells.

- Diffused light is from lower hemisphere is transmitted and serves
as interior illumination.

The curtain wall comprises of a solar prismatic array having a
beehive appearance with mounted solar cells each cell pointing
upwards. Double glazing applied in the back and font completes the
overall curtain wall design allowing improved thermal isolation. With
a simple yet innovative design it is time to summarize main system
advantages.

a. Lout

- Front plane - Low Iron Glass
- Interlayer - LCPV with Solar Cells
- Rear Plane - Float Glass (Thickness according to static load
requirements.)

b. Characteristics of SoalrOr's BIPV Module are as follows:

- Optimal design for vertical installation offers the best sun
harvesting performance.
- Translucent technology permits light transmission and provides
noise insulation.
- Total internal reflection technology enables back reflection
(towards the sun) of excessive sun energy.
- Best price performance in the industry.

2. LCPV Utility Scale Product Line

Since 2009 the worldwide crisis drove the silicon based panels
pricing down to earth where the LCPV Utility Scale Products promise
to drive prices further down.

Based on a unique mirror concentration technique ratio of 3 and
actual concentration exceeding 2.5, this technology will drive its
cots toward 1EUR/Wp in the near future. Together with a built-in
proprietary efficient tracker, this technology is offering solar kilo
watt hour pricing with near grid parity by replacing expensive
silicon material with reflective solar mirrors.

In summary characteristics of SolarOr's LCPV module and
applications are as follows:

Characteristics of SolarOr's LCPV Module

- Innovative proprietary design with high accuracy, built-in
dual-axis tracker.
