"Energy Source largest in the world, the source of life of every
plant and animal, but still the source used so little? Today is the
sun. This energy can be converted into a driving force, dynamic
and electric, and even after exhausting all uranium and thorium
from? Earth Energy sun will continue to flow to us almost without
limit "? David Ben-Gurion in 1956
Picture: Dr. Zvi Tabor and Prime Minister David Ben-Gurion imply the
panel's first solar developed Tabor International Laboratory for Physics

policy guidelines in renewable energy
• Creating certainty in renewable energy electricity
generation in clarifying the goals by 2020.
• Encouraging the construction of electric power
plants using renewable energy in Israel in general
and in particular the outlying areas.
• Increasing the energy security of the State of Israel.
• Encouraging electricity generation technologies
"friendly" environment.
• Increasing electricity generation from renewable
energy sources while reducing the cost burden for
consumers.

The heart of the development of photovoltaic private
industry market in Israel and its neighbors will be
reflected in the way we produce, distribute and
consume energy
 Renewable energy sources in 2012 accounted for only 5% of primary energy
consumption in Israel, where the main energy source is utilized mainly solar
water heaters.
 For power generation renewable energy contributing only about half a percent,
which is the lowest rate in the world. In contrast, the supply of solar heating
contributes approximately 39%, which is the highest rate in the world. As of
2012, still about 95% - Israel's primary energy supply comes largely imported
fossil fuels.
The market PV world grew by more than 40% a year in recent years and turns
valuable contribution for electricity generation.
 Energy PV is important because of the nature decentralized / centralized,
flexible use of the urban environment and there is a huge potential to lower
costs.
 Industrial photovoltaic exploiting the potential of a more and more in recent
years, with the most downloaded installation prices in half in recent years.
 Existing developments focused on improving existing modules and system
components by improving energy efficiency and reduced use of materials.

An advanced system for hybrid solar (PV-T)) produces simultaneously
electricity (photovoltaic) and hot water (solar thermal) for homes and
buildings combines photovoltaic panel with a heat exchanger on the
bottom board, to produce 2 to 4 times more energy than photovoltaic
traditionally panel. The solution is ideal for new regulations for energy
efficiency and is designed to make homes and buildings to power
stations Mini positive energy..
1. Innovative heat
exchanger:
completely
integrated into the
board, allowing
excellent heat
transfer between the
photovoltaic panel
front and the water
flow.
2. Super slim
design: standard
dimensions of the
photovoltaic panel
(cell 6 inches, 60
cells).
3. High-performance
photovoltaic cells
volts: mono-
crystalline, high
efficiency, cooled by
water flow.
Hybrid system

2in 1 integrated system to produce
electricity + hot water
 The hybrid system provides hot water and electricity, and is a nice solution
for private homes, new construction, government offices, schools, new PV
installations, or to existing PV.
 The solar panels capture the wasted heat of the solar panels and turn up
the heat in their water and electricity for a private home.
 This hybrid solution provides incredible 60-70% of solar energy compared
to 15-20% with a PV system, which means watt manufacturing cost is cut
in half as a result of "heat extraction“ of the PV cells and converting them
into electricity.
 Solar systems hidden under the PV panels and requires no additional roof
space, as opposed to separate solar thermal systems.

Volther Hybrid PV- T Panels
PARADOX & PROBLEM
Photovoltaics (PV) are semi conductors and operate in a
paradox.
They need sunlight to generate electricity but suffer a
degradation in performance as they get hotter.

A typical PV Efficiency
A typical PV panel on
a bright sunny day will reach
temperatures in excess of 110°C.
This can reduce efficiency
by as much as 43% on a hot day
or 0.5% for every 1°C temperature
rise. Standard PV Panels typically
only convert 10-15% of solar
radiation into electricity and the rest
is dissipated as waste heat.

PV.T POWERVOLT Type
 PV.T Developed to maximize the
electrical return of the hybrid panel
 Produces up to 50% more than an
equivalent standard PV collector and also
produces a reasonable amount of usable
heat.
Peak Panel Outputs:
190w Electrical
460w Thermal (1,570 Btu/Hr)
16m2 of PV-T panels give equivalent
performance to 21m2 of standard PV
panels and 4m2 of standard thermal
collectors.
Size of Panel = 828x1655x90mm
Type of PV cells: Mono-Crystalline
Weight: 24,4 kg

PV.T POWERTHERM Type
 Developed to maximize the thermal return of the hybrid panel
 Contains an extra layer of low - iron solar glass to aid heat
retention
Produces approx. 80% of an equivalent standard thermal
collector and also produces electricity
 Peak Panel Outputs:
170w Electrical
 610w Thermal (2,080 Btu/Hr)
 Size of Panel = 860x1660x105mm
Type of PV cells: Mono-crystalline
Weight: 34,4 kg

6.75KW system performance

For Pitched Roofs
 Pitched roof mounting kits are
designed with ease of installation
and aesthetics in mind.
We developed mounting
systems with hanger bolts and
roof brackets as well as
accessories for all roof types.

For Flat Roofs
 Using the Premium Flat roof mounting
system, PV-T panels can be installed on
flat roofs of every type.
Together with the module frames, the
rear supports of the mounting elements
form a static unit capable of bearing
particularly heavy loads.
It is possible to make installation
horizontally or vertically

For Roofs Integration
 Roof integrated mounting option allows highest- flexibility to choose between landscape
and portrait orientation and to arrange the respective PV-T modules according to your own
preferences. The advantages of this method of installation include perfect integration of
panels so they lie particularly flat on the roof, and the very slender appearance of the system.
While aesthetic considerations take precedence, the performance of the cells will never be
a problem.

System Components
Typical system components are listed below.
Actual configuration will vary according to each application:
 PV-T Panels
Inverter
Control System & Sensors
Pump Station
Heat Exchanger
Hot Water Storage Tank
Mounting kit
Cables and Pipes

Optional System Components
The PV-T panels can be used in conjunction with other
technologies to further enhance energy efficiency if
desired. Examples are:
 Geothermal Heat Storage: Excess heat produced by the PV-T panels can be
stored in the ground for use at a later time => summer heat can be used into the
winter to maximize energy use.
 Battery Storage System: Can be used to create an off-grid system => excess
electricity generated during daytime can be stored and used at night.
 Fuel Cell Storage:
Excess electricity from daytime can be used to generate hydrogen for use in a fuel
cell system at night.

Case Study

The largest Hybrid PVT installation in the UK to date and the first to use the new Vother
PowerVoltpanels. The installation has a combination of PowerTherm and PowerVolt, making this
Installation a world first by using both types of Hybrid collector. The heat from the system is being
used for the building with excess heat being vented through a 30 kW fan assisted heat dump.

Great setup of the hybrid system to generate
electricity on the roof of the Federal Building
in Boston
Boston, MA – The U.S. General Services Administration has committed itself to
sustainability at an Earth Day event held today at the Thomas P. O’Neill, Jr. Federal
Building.
This solar energy system is designed to produce electricity and hot water through the use
of an innovative photovoltaic-thermal hybrid technology that combines a solar panel and
thermal collector into a single module. The installed array of hybrid modules will produce
approximately 30,000 watts of electricity and 69,000 watts of thermal energy to heat
water. The reduction in greenhouse gas emissions associated with this project is
estimated to be approximately 64,904 pounds of carbon dioxide, equivalent to the work of
4,993 mature trees. The system is the largest rooftop hybrid solar installation in the U.S
and is also the first installation of photovoltaic-thermal hybrid solar technology on a federal
or commercial building.

Is one day we dare to look in the eyes of our children
and to admit that we had the chance but we did not
have the courage ? We had the technology, but we
did not have a vision?
