and the thermal yield is about 1.2 GJ/m

year. The PV/T collectors have three
available sizes, e.g. 1,800 9 1,800, 900 9 5,600 and 1,800 9 2,400 mm, and are
suitable for being integrated into tilted or flat roofs using a common connection
method.
The Israel-based 'Millennium Electric Ltd' has developed a MULTI SOLAR
PV/T System that enables conversion of solar energy into thermal and electrical
energy simultaneously using a single hybrid system, as shown in Fig.

. The
MULTI SOLAR PV/T System is made of facade/roof-tile-like panels which
behave as a 'living' skin around the building allowing the flow of water to cool the
PV cells, capture heat and store it in an insulated tank, thus enabling heat control
of the living environment. The system can generate 30 % higher PV efficiency in
production of electricity for domestic use.
In terms of PV/T concentrators, three major manufacturers in the world, namely
Absolicon in Sweden, Menova Energy in Canada and HelioDynamics in the UK,
involved with this kind of business. 'Absolicon' produced an X10 PV/T com-
mercial heat and power system, as shown in Fig.

. The system consists of a
cylinder-parabolic reflector that concentrates ten times the solar light onto the
receiver. It is also equipped with the latest generation of photovoltaic technology
