BASEL, Switzerland, April 21, 2010 - At this year's Intersolar, TRITEC will present the new generation of the
characteristic curve measuring device TRI-KA: The most significant
innovations are increased input range for current and voltage, two reference
cells at the irradiation sensor, enhanced menu navigation with touch screen
and a new analytical software.

The Swiss photovoltaics distributor and system integrator TRITEC has
developed the new characteristic curve measuring device TRI-KA II that is
perfectly tailored to today's and future needs of PV installers. Using the
characteristic curve analysis, the PV system's output can be measured during
installation, hand-over or maintenance of the system and compared with the
nominal output. Work with the characteristic curve measuring device TRI-KA
could not be more efficient: The device handles very easily and its use is
extremely flexible and variable due to its technical advancements.

In addition, the measuring procedure of the TRI-KA, combined with the
TRI-SEN, is extremely simple. The radio link between the irradiation and
temperature sensor TRI-SEN on the roof and the analytical device TRI-KA at
the inverters in the basement allows for an uncomplicated wireless
measurement of the off-load voltage and the short-circuit current of the
system. Thanks to the increased input range for current (0.1 to 15 A) and
voltage (1 to 1000 V), both individual modules and entire strings can be
measured. The TRI-SEN now has two reference cells (mono- and poly-crystalline
), and thus the sensor provides more precise irradiation values and the
results are even more conclusive.

The TRI-KA is supplied as a full set in a high-quality case, which
contains everything needed for characteristic curve analyses. Due to its
easily manageable size, low weight and sturdy casing, the TRI-KA is perfectly
suited to be used on the roof and in the field.

Also new is the operation of the TRI-KA via a touch screen with enhanced
menu navigation. Furthermore, the software for the analysis of the readings
has been completely revised and designed even more user-friendly in
collaboration with installers. The software can be navigated intuitively and
without much prior knowledge. It guides the user through the analysis step by
step. The programme is downwards compatible so that older measurements can
still be read.

Using the TRI-KA to analyse the characteristic curve opens up totally new
ways to prove quality and reliability:

    - An innovation is the possibility of acceptance protocols during
      hand-over of the system to the client

    - With a few clicks the output of a system can be monitored over several
      years

    - Errors and defects of the system can easily be identified

The end users will feel the benefit of the characteristic curve analysis
mainly in terms of money: A system installed and maintained in the best
possible way will ensure that they achieve maximum yields.

Measuring Procedure

1. Surface temperature of modules can be measured without contact using
the TRI-SEN

2. Install the TRI-SEN at the same level as the modules and measure the
irradiation

3. Use the TRI-KA to measure the off-load voltage and short-circuit
current of the system

4. Establish the current/voltage characteristic curve of the system with
the TRI-KA

5. Wireless transfer of measurements from the TRI-SEN to the TRI-KA

6. Import results from the SD card of the TRI-KA to the PC and analyse
them using the software
