MAKING USE OF SOLAR ENERGY
Solar energy is among the most abundant and available free renewable energies on the earth’s surface. To have an idea of
the energy that the sun radiates onto the earth, according to the latitude, the average daily solar radiation in Italy varies
from 4 to 5.5 kWh on a surface of 1 square metre.
The use of a solar heat collector with vacuum technology is accredited, as shown by the experts in the solar sector and
by laboratory tests carried out according to EN European Standards, to be the most technically efficient system for captu-
ring the energy released by the sun through the entire year.
Considering the daily heat energy request per person for domestic hot water use, the use of solar collectors with vacuum
technology with CPC reflector, combined with a standard state-of-the-art designed system, allows energy saving regarding
domestic hot water of up to 80%. While, considering the global load of heat energy requested for domestic hot water and
heating, the total saving can exceed 40%.
This considerable energy saving constitutes an important contribution to the reduction of the emissions of noxious
substances, deriving from combustion, into the atmosphere and particularly to the reduction of CO2, the main reason for
environmental heating due to the greenhouse effect.
The functioning principle of a solar heating system can be described simply.
The solar vacuum collector with CPC reflector captures solar radiation and heats up. The heat gathered is transferred by
heat exchage to a water tank, which acts as a storage tank. The amount of solar energy that the collector can transfer to
the tank depends on its capacity to absorb solar radiation and on the level of insulation, which reduces the loss of energy
captured by the collector.
The creation of the vacuum by removing the air from the gap in the glass tube achieves a layer of the best heat insulating
material existing in nature. The principle has been known about for a century and is appreciated in the form of the
thermos.
Using this arrangement, the collectors optimise the use of solar energy also during the change of seasons and during the
winter.
ADVANTAGES OF CPC DIFFUSION VACUUM TECHNOLOGY
- High temperatures and yields even in unfavourable atmospheric conditions, e.g. with low external temperatures.
- High absorption even with diagonal light thanks to the circular shape of the absorbing device.
- Top quality and high efficiency solar vacuum tube, of our own production and with high level of forced vacuum.
- Duration through time: no delicate glass-metal couplings that degenerate the level of vacuum in the glass pipe through
time.
- Duration through time: high resistance and duration of the selective capturing layer also thanks to the protection of the
vacuum.
- Loss of load contained thanks to the circulation of the flow in parallel in the circuit with "U"-shaped pipes.
- Maximum yield with less requirement for surfaces (half of the absorbant surfaces are normally necessary with respect
to a traditional absorbing panel).
- Treated spacial aluminium concentrator reflector, with double CPC paraboloidal section (Compound Parabolic
Concentrator) with optimised optics for the solar collector, to convey the sun’s non-incident rays onto the vacuum tube.
- High efficiency all year round.
- Low assembly costs: collector already assembled and easy to fix.
- Easy and immediate tube replacement with the EASY CHANGE system.
- Excellent heat insulation performance of the heat-carrying circuit also at low temperatures.
- Modern and elegant design.

THE VACUUM TUBE
AN OLD PRINCIPLE APPLIED TO AN INNOVATIVE TECHNOLOGY
The creation of the vacuum by removing the air from the gap in the glass tube achieves the best heat insulating material
possible. The principle has been known about for a century and is appreciated in the form of the thermos.
Using this arrangement, the collectors optimise the use of solar energy also during the change of seasons and during the
winter.
The internal surface of the vacuum gap is made selective to the absorption of the solar radiation by means of the laying,
by sputtering, of multiple metal layers with a micro-metric thickness, which is called CERMET and which cover the
absorption of the entire spectrum of electro-magnetic radiation of the sun.
The selective layer is designed especially to resist the high temperatures that are generated, through time. The presence
of the vacuum ensures the protection against infiltrations of humidity and atmospheric agents, thus guaranteeing unlimi-
ted duration and the maintenance of the capturing perfomance.
TRANSMISSION OF HEAT TO THE HEAT-CARRYING FLUID
The exchange of the heat collected takes place by a relevant absorbing device in aluminium, which on contact with a “U”
-shaped copper pipe transfers the heat to a heat-carrying fluid present in the solar collector circuit.

WHY CHOOSE KLOBEN
The research carried out to increase the yield of the Kloben solar collectors have allowed to discover efficient and
innovative solutions to make the best of the sun and its diffused light. For this reason particular direct and diffused light
capturers, with CPC, Compound Parabolic Concentrator, geometry have been studied and realised using materials able to
supply optimal yields in total reflection (> 90%) and in reflection with diffused light.
The combination of vacuum tube technology and CPC reflectors applied to the solar collectors, guarantee the best yields,
most of all in situations of little radiation and low external temperatures. The advantage of the Kloben system therefore
has an immediate effect also at an economical level.
Efficiency curve with radiation at 800 W and average temperature inside heat-carrying fluid of 50°C of the Kloben SKY
CPC 58 DIFFISION model (Test Report no. 07COL623/1 (according to EN 12975-2:2006), ITW Institute, Stuttgart - Solar
Keymark certification).
Efficiency curve with radiation at 800 W and average temperature inside heat-carrying fluid of 50°C of a Solar Keymark
certified flat solar panel (data from Solar Keymark Database - Estif site, (European Solar Thermal Industry Federation))
From the comparison it was seen that for an average T of heat-carrying fluid of 50°C, the Kloben SKY CPC 58 Diffusion
vacuum collector has greater efficiency that the flat collector, up to 35°C of environment T. The difference in efficiency
increases even more on the decrease of the external temperature.

Dimensioning
Kloben makes use of a complex software that allows quick, precise and customised calculation of the enrgy requirements
requested, the number of panels necessary and the solar integration supplied, in relation to the destination of use of the
solar system, the details of the structure on which it is to be applied and the climatic data referring to the area of
installation.
For the dimensioning of all components, it is recommended to contact Kloben-authorised staff. However, it is possible to
perform approximate dimensioning of the components necessary for small solar systems (systems up to max 10 m2of solar
collector surface, optimal exposure of collectors max 20° from South and inclination at 45°, average daily consumption
per person of about 60 litres at 45°C), using the data shown below:

Checks and parameters indispensable for dimensioning
In order to start with a correct design, aimed at the realisation of the solar system that is the most suitable for maximising
the benefits of the final customer, some important preliminary checks must be carried out and indispensable data must be
gathered for correct dimensioning:
PROJECT LOCALITY:
The locality where the system is to be installed supplies precious indications for dimensioning, such as: average monthly
radiation, average monthly external temperature, mains water average monthly temperature, average relative humidity
temperature, average monthly wind speed.
METHOD OF CONSUMPTION AND PERIOD OF USE OF THE SYSTEM:
Consider the daily requirement of the family; an approximate consumption of hot water at 45°C variable from 50 to 70
l/day per person. Identify any simultaneous requests for the use of domestic hot water. Check the period of use of the
system (seasonal or months of use).
TYPE OF SYSTEM USE:
heating domestic hot water: identify the consumption and temperature of the water requested and the capacity
of the existing storage tank. For maximum dimensionimg of the capacity of the storage tank to be envisioned, it
is possible to refer to about the double of the daily consumption envisioned for the family or inhabitants.
heating non-domestic hot water: hotel, gym etc.-indicating that stated previously regarding the methods of
consumption and periods of use. For this type of system, therefore, an ad hoc design by designers or Kloben tech
nical staff is always necessary.
room heating: only radiating - identify surfaces to be heated, space between tubes and type of insulation.
swimming pool: specifies if covered or outdoor, any night cover use, requested temperature, period of use.
FEATURES OF THE INSTALLATION STRUCTURE:
The surfaces that house the field of solar collectors are an important restriction of the design, which must be considered
as the positioning of the solar collector affects the capturing efficiency of the sun’s radiation. The checks to be carried out
are: possibility of assembly on flat or sloped roof, availability of roof pitch with orientation towards the south or
alternatively with orientation towards east or west, inclination of the pitch, presence of obstacles, etc.
From the existing Standard, UNI 9182, the data inherent to flow rates and requirement of domestic hot water according
to the activity in question and the single appliances, are gathered.
The dimensioning indications stated above refer to maximum dimensioning and are relative to homes with the standard
consumtion of an average family. However, for the correct dimensioning of all parts of the system, it is necessary to
consider the preliminary checks indicated along with all of the details of use of the final user to then proceed with the
definition of the energy requested, the modes of distribution (flow rates, temperatures, period of request) and
successively with the correct dimensioning of all system components on the basis of powers and exchange yields of the
various components: solar surface, solar heat exchanges, storage, etc.
For this reason and for accurate dimensioning refer to Kloben specialised technical staff.
N.B. IF THE SOLAR INSTALLATION IS INTRODUCED ONTO SYSTEMS THAT ALREADY
FUNCTION, IT IS INDISPENSABLE TO HAVE THE DETAILED LAYOUT OF THE EXISTING
HEATING STATION, WITHOUT WHICH IT WILL NOT BE POSSIBLE TO SUPPLY ANY
PERFORMANCE GUARANTEE.

Warnings and preliminary checks
The installer is asked to carefully follow the recommendations and indications that are listed successively; as well as
performing all controls requested before system start-up.
ANTI-FREEZE HEAT-CARRYING FLUID:
The heat-carrying fluid used and supplied consists in a special liquid with anti-freeze properties, TYFOCOR LS. This fluid
is specially for use in solar plants with high heat yield like vacuum tube collectors. It is totally pre-mixed and ready for
use. It guarantees protection from freezing to -28°C.
It contains corrosion inhibitors that guarantee efficient protection and duration of the copper pipes, (and all other metals
and alloys used) in particular from corrosion and deposits.
Warnings: In order to maintain the protective features of TYFOCOR LS unaltered, it must not be mixed with other
heat-carrying fluids and anti-freeze or diluted with water. Any top-up owing to the loss of fluid must be compensated
exclusively with TYFOCOR LS. Before loading always check that there is no water in the circuit.
The use of deposited metals is advised for soldering. For welding points the use of deposited metals is recommended for
brazing in silver and copper.
TYFOCOR LS does not attack the sealing materials normally used in solar systems. However, attention must be paid that
all sealing materials are resistant to the maximum temperature of the heat-carrying fluid. Failure to comply with these
checks can lead to the warranty of the solar collector becoming void.
LOADING:
- Before starting the system loading operation, make sure that the solar collectors are at low temperature.
The panels must be covered at least 3 hours before loading.
- The system must be loaded by carefully following the instructions given on page 25 of this manual. The use of the
supplied system loading pump is also recommended (code 101010045).
Correct loading allows the complete elimination of air in the solar circuit and its correct functioning.
- The system’s optimal functioning pressure, to be calibrated in the loading phase is 3/3.5 bar in the heating station and
at least 2/2.5 bar at the panels, with the system at a standstill.
DIMENSIONING:
- Before starting the solar system it is good practice to check that dimensioning and the adjustment of the individual
components ( panels, expansion vessel, glycol, flow rate adjuster, solar station) are in compliance with that indicated on
page 5 of this manual.
- It is indispensable that the diameter of the copper pipes making up the solar circuit are in compliance with that
indicated on page 11 of the following manual. If in doubt, refer to Kloben authorised staff or our technical dept.
INSTALLATION AND RESISTANCE TO LOADING STRESS, WIND AND SNOW:
The installation of solar collectors on flat and sloped roofs envisions indispensable preliminary checks that clarify the
following critical aspects:
- Static stability of the roof for assembly of the collectors
- Accessibility of the roof housing the system and sufficient access and freedom of movement in safety
- Fixing quality of the structure connections and support devices of the solar collectors to the building support (loft
structure, flat roof structure, etc.).
On the basis of the place of installation selected, the locality, the height from the ground, exposure, topography of the
land, the climatic conditions of the areas, etc. preliminary checks must be made of the loading conditions owing to the
wind (average, peaks due to gusts and the presence of storms) and snow on the basis of that envisioned by the
"Departmental Circular dated 4 July 1996, n. 156" regarding implementation "technical standards relative to the general
criteria regarding the safety checks of the constructions and loads and overloads", Legislative Decree dated 16 January
1996.
In the calculations regarding the evaluation of stress of individual and combined loads owing to wind and snowfall, a
maximum sustainable load must be considered, normal to the surface of the collector of 0.90 kN/m2.
The solar collector has been designed to suitably resist combined conditions of wind and snow, the most serious
features of the Italian territory. However, if phenomena of an exceptional nature should occur or situations or loads
exceeding the maximum load of the panel it is good practice to prepare additional protections, such as tie-rods and
Manuale_03_03_08 UK.qxd:Manuale_18_04_07.qxd 26-05-2008 11:23 Pagina 11

12
reinforcements for stabilisation.
MATERIALS:
- All pipes making up the solar circuit must be in copper. The use of other materials such as zinc, stainless steel, plastic,
brass and similar is not recommended. If materials different from copper are used, it will be impossible to guarantee
correct functioning of the system.
- All joints must be welded or with tightening connections for copper pipes.
The use of any other materials can jeopardise the sealing of the joints through time.
- To prevent sealing problems of the hydraulic joints of the solar circuit owing to heat stress, always check the distance
at which the field of solar collectors is found with respect to the storage tanks. In all cases it is recommended always
to make the joints with high temperature Teflon.
- The copper pipes must be insulated using a sheath for high temperatures such as the Kloben Solare.
CHECKS:
- Check that, with the system unloaded, the expansion vessel is calibrated at 2 bar.
- Check the correct connection of the probes to the solar control unit.
- Check that the solar control unit is connected correctly to the mains.
- Check that the setting of the solar control unit parameters is in compliance with that prescribed in the design phase.
N.B.: The solar collectors cannot remain exposed to solar radiation for long periods of time without being
loaded (ten days).
