The direct use of solar energy by
the auto-consumption in buildings
gets more and more important to
minimize negative grid influences.
Therefore the BFH PVLab launched
the project PVOB that will help to
optimize photovoltaic applications
in building envelopes to match the
user’s energy consumption and
reduce negative grid influences.
Creating a data base by measuring
and evaluating buildings with PV
installations on all sides on
building façades will be one part
of the project. Furthermore cost
optimization in planning and
realisation processes, as well
improvements of fire prevention
are
aspects
which
will
be
integrated.
The analyses of daily power profiles
of the PV-installations and the power
demand set of the users will give
exactly information of the match of
energy production and demand. This
enable a maximization of PV autoconsumption. Such a kind of
installations provide a longer and
more stable production of PV
electricity and lower, for example,
the handling problems of peak PV
power in the grid.
Fire protection of PVOB applications
PVOB: PV application for less grid overloads during
the daytime.
Fire prevention by electric arc detection
The combination of PV panels and
building material occurred a higher
risk of fire in the envelope of a
building. Less ventilated PV panels
and higher temperatures leads to
more technical failures and increase
fire danger.
The BFH PV-Lab will define technical
strategies against electric arcs and
hot
spots.
Stress
Test
of
components and frequently failure
detection by electrical arc detectors
and IR-measuring are parts of the
project.
Monitoring of PVOB applications
The BFH PVLab is going to measure
different multi-level houses with PVinstallations on each façade and also
houses
with
east-west
PV
installations.
Cost optimization of planning processes
The complexity of planning and
realisation of PVOB projects are
higher than for standard PVinstallations. Different players, like
architects, constructing engineers
and solar engineers are typically
involved
in
PVOB
projects.
Improvements in planning and
realisation processes will save cost
on each project. Support will be
given by planning tools and the
guideline for Photovoltaic Oriented
Buildings PVOB developed at BFH
PVLab.
Hot spot defect analyses with drone and IR-camera.
Future Efforts
All results will be summarized in a
“Guidelines for Photovoltaic Oriented
Buildings PVOB” that enable the
architect , technical engineers and
installer to realize economically and
technically safety PVOB projects.
