and a solar tracking system using special electrical custom-designed high-quality
linear actuators. The aim is to rotate the X10 concentrator to allow the sunlight to
be focused onto the cells all the time. The tracking system has a built-in program
that can automatically protect the photovoltaic cells from being overheated or from
storms. If the temperature exceeds a certain value, the X10 automatically turns the
receiver away from the sun.
'Menova Energy' provides the Power-Spar PV/T concentrator for use in
domestic application, as shown in Fig.
18
. The Power-Spar model has been spe-
cifically engineered to provide enhanced performance even when being exposed to
extreme winter temperature.
'HelioDynamics' provides a tracking, modular PV/T concentrator, namely
'Harmony HD 211', as shown in Fig.
19
. It is designed for being mounted on the
flat and sloping roofs or pole-mounted over parking areas at the mid-latitudes
(20-40).
The ventilated PV with heat recovery is a type of recently emerged PV/T air
collector system. The system is designated to provide solutions for ventilating the
PV cells to maximise the electrical yield and utilizing the PV heat for preheating
the ventilation air. Standardised products for this purpose have been manufactured
in Secco Sistemi, an Italian PV manufacturers, as shown in Fig.

. This type of
system has been used in various engineering projects including the Fiat Research
