3.5 Energy Rating comparison services
In 2007, four Energy Rating comparison in field were performed for third-parties. Some of them
including:
� Initial I-V measurement at STC;
� exposure at Voc for first degradation (20kWh/m2);
� second I-V at STC for reference;
� exposure at MPPT for an insolation ranging from 100kWh/m2 to 400kW/m2;
� final I-V measurement at STC.
3.6 MPPT3000 development
During 2007 collaborations with 6 institutes (either Universities and manufactures) have been
achieved for the installation of systems equipped with MPPT3K testing devices which were developed
by ISAAC-TISO.
The communications software "MPP3K Manager" has been improved. The firmware of the DSP has
also been improved; an auto-range and new indicators of setup were added.
3.7 BIPV
The introduction of photovoltaic plants into the building environment requires a sensitivity and nontechnical
knowledge which installers often lack. Although BIPV (Building Integrated PV) makes up
only a small part of the overall PV market, it is becoming increasingly important for the eventual acceptance
of PV. The photovoltaic module is no longer a building accessory which disfigures, but it is becoming
a building element which has a role in the creation of the entire envelope of a building.
In the case of BiPV integration, due consideration at the beginning of a project will permit better integration
from aesthetic, energetic and economic points of view. The architect must therefore have the
knowledge and the tools to promote photovoltaic integration in a building. He must be aware of the
possibilities, the obligations, the advantages and the disadvantages. In order to help them a new
homepage dedicated to BIPV was created.

ISAAC-TISO participates also as
external work partner at the subproject
SP6 of the PERFORMANCE
project in 6 th European Framework
programme. The rule of ISAAC in
this sub-project is to provide input
on present regulations and building
codes in Switzerland and to participate
actively in the work-package
dealing with the development of
tests for novel BIPV technologies.
� In April 2007 the seventh quality audit, for the ISO17025 accreditation maintenance of the sun
simulator, supervised by the Swiss Accreditation Service, was successfully passed.
� A total of 342 indoor I-V measurement were performed for third-parties.
� In addition for several modules other measurements were executed: 22 determination of the temperature
coefficients; 21 I-V characterization at different irradiances (200, 400, 600 and 800
W/m²); 47 outdoor initial degradation (20-40 kWh/m²); I-V determination with multiflash method;
Visual inspection and insulation test according to IEC 61215; Electrical continuity test; By-pass
diode test.
