2010 Energea Engineering, the Energea Group’s research and
development company, begun to study how to exploit the solar energy
as a renewable resource, this path led to the realization of a
cutting edge system in order to produce energy saving fossil fuels:
this is Solar Power System.
The core of this system is the innovative photovoltaic-thermal
hybrid panel, wholly developed by Energea Engineering, in collaboration
with the Physics Department of the University of Ferrara and with
Istituto Giordano. This panel allows the simultaneous production
of electric energy and hot sanitary water, and a surplus of thermal
energy which can be used in accordance to the customer’s
This panel, patented in 2011, has a refrigerating coil in order
to produce hot water and to cool photovoltaic cells: as a consequence
electric efficiency increases. In addition to this coil, there
are two heat-pipe evacuated tubes which provide high temperature
hot water that can be used together with the one coming from the
coil and/or in order to produce other types of energy.
Power System is a photovoltaic-thermal hybrid panel,
born from the research and innovation of Energea Engineering,
which produce electricity, hot sanitary water and high temperature
hot water using solar energy. This is an all-in-one PVT panel.
IS IT FOR?
is an innovative system to produce electricity and hot water (sanitary
at medium temperatures and at high temperatures), this aim can
be achieved installing only one type of solar panel: if you install
the SPS, you won’t need a photovoltaic and a solar thermal
plant to satisfy your needs anymore.
Using this system in private houses you can fill any requirement
of hot sanitary water, rooms heating and electrical energy. In
the industrial field the SPS allow to save a lot of energy.
For example, a factory which has a correctly dimensioned SPS plant
Electric energy in order to satisfy part of its
requirements, if there’s a surplus of energy it could be
feed in the network accessing the “Feed-in” tariff.
Hot water will be available during the whole
year: from May to September it will be guaranteed by the middle
temperature section, in the wintertime hot water will be provided
by the evacuated tubes which work even in harsh weather.
If there is a long period with bad weather and harsh temperatures
it will be luckily not to reach the right temperature, in this
case electric energy from photovoltaic panels could be used for
this goal. Even in this extraordinary situation the electric energy
balance will be positive, for the benefit of the society and the
Solar cooling, electricity or thermal energy
for industrial processes: from May to September, when the cooling
coil supplies hot water needs, the surplus of thermal energy could
be used in order to increase the global efficiency.
IS IT MADE?
module is made of four parts:
Photovoltaic panel: It is an highly reliable
and efficient panel with monocrystalline cells in order to have
the best performance.
Hot sanitary water coil: Behind the photovoltaic
panel there is an aluminium coil in which flows a working fluid
which take the heat away from the panel and release it to the
sanitary water in an thermal store (boiler).
High temperature water collectors: On both
sides of the panel there is one heat-pipe evacuated tube, on
the first hand to produce high temperature hot water (100°C
temperature can be reached), on the second hand in order to
guarantee hot sanitary water supply when outdoor temperature
is too low and the back coil does not warm enough the sanitary
Control system: It is designed ad hoc in order
to monitor and control each parameter of the plant.
IS IT INSTALLED?

southern exposure (roof, terrace, field). If the tilt angle
of the area is not optimal, they will be installed with appropriate
We use well-established installation techniques and technologies,
this is a guarantee of reliability and ease to assembling.
The photovoltaic part of the panel is linked
to the electricity network with common devices (inverters, control
systems, energy meters, etc…)
The back coil (medium temperature part) is
linked to a thermal store with a well-established active system.
evacuated tubes (high temperature part) is connected
to valves in order to direct the flow to the thermal store (if
there is hot sanitary water requirement in wintertime) or to
a recovery energy system. Customized configurations could be
There is an electronic control system expressly
conceived to manage different parts of the plant and to monitor
operative parameters of the Solar Power System, using several
sensors. Our trained technicians could easily set the control
system in order to fit the customer’s requirements, anytime
it is needed.
LONG WILL IT LAST?
and thermal energy productions are guarantee for 20 years.
I ACCESS INCENTIVES?
SPS you can access the Feed-in tariff for the
photovoltaic part, and the tax deduction for the thermal part.
