2Benefits and advantages
2. Benefits and advantages
Intelligent design and assembly:
• Suitable for pitch roof and flat roof mounting as well as for the free standing mounting and façade assembly• For heating of drinking water and operating water for part-solar heating and swimming pool water, as well as
for solar cooling
• High flexibility through collector modules with varying widths
• Connectable up to 15 m2 in series
• Outstanding Design
• Short assembling times due to completely prefabricated collector units and simple flexible rooftop and flat
roof assembly sets
• Simple connection technique for the extension of several collectors next to each other with pre-mounted
connectors. No further pipe work or extensive thermal insulation required
• Solar advance and return flow can take place alternatively on the left of or on the right at the collector
• Exchange of the tubes is possible without emptying of the collector circuit - „dry binding“
• Simple connection of the hydraulic lines by clamping ring connector technology.
Operating reliability:
• High working reliability and long service life by application of high-quality, corrosion-proof materials like
thick-walled borosilicate glass, copper, and corrosion-coated aluminum.
• Permanent vacuum-tightness of the tubes, due to pure glass fusion, no metal-glass transitions, principle
thermos flask.
• High working reliability by „dry binding“ of the evacuated tube to the solar set.
Recycling:
Fully recyclable by dismantle-friendly construction and reusable materials.
Energy yield and performance:
• Extremely high energy yield with small collector gross area.
• Due to circular absorber area, each individual tube has always the optimal adjustment towards the sun.
• Unusually high solar covering rates possible.
• High efficiency through highly selective absorber coating.
• The evacuated tubes reduce the thermal losses of a solar collector with high efficiency, since in the vacuum
there is no air which could transport the heat from the absorber surface to the external glass tube which is
subject to weather influences.
• The heat distribution medium is conducted directly through the tube without a heat exchanger inserted intothe collector.
• Both direct and diffuse solar radiation at varying irradiation angles are always optimally collected by the
circular absorber.
• The CPC mirror and the direct flow through the evacuated tube contribute substantially to the extremely high
energy yield.
• Optimum thermal insulation by vacuum, thereby high efficiencies also even in the winter season and at low
irradiation.
• Unused surplus in summer is lower than with a flat-panel collector. But the gains in winter are substantially
higher.
• Ideally suited also for low-flow systems with layer load and heating support.

3Design and function of the collectors
3. Design and function of the collectors
Historical roots – the invention of the thermos flask
In 1893, Scottish physicist James Dewar invented a double-walled vessel with a vacuum-insulated gap - the
thermos flask.
Based on the principle of the thermos flask, already in 1909 Emmet developed evacuated tubes in order to make
solar power usable. Even today, his patents from that time are the basis for modern evacuated tube technology.
However, the efficiency of this old and well-known technology of the thermos flask could be brought to the highest
level only with the help of modern coating technologies and highly selective layers.
The technology - today
The Ritter Solar evacuated tube collector consists of 3 main components which are completely pre-assembled:
• evacuated tubes,
• CPC mirrors, and• collecting box with heat transfer unit.
The evacuated tube
The evacuated tube is a product that is optimized in geometry and performance.
The tubes are composed of two concentric glass tubes which in each case are half spherically closed on one
side and fused together on the other side. The gap between the tubes is evacuated and afterwards hermetically
plugged (vacuum insulation).
In order to make solar power usable, the internal glass tube is provided on its external surface with an
environmentally friendly, highly selective layer and thus designed as an absorber. This coating is thus protected
within the vacuum gap. It is an aluminum nitrite sputter layer which is characterized by very low emission and
very good absorption.

3Design and function of the collectors
The CPC mirror
In order to increase the efficiency of the evacuated tubes, a highly reflecting, weather-proof CPC mirror
(Compound Parabolic Concentrator) is placed behind the evacuated tubes. The special mirror geometry ensures
that even at unfavorable irradiation angles direct and diffuse sunlight falls onto the absorber. This substantially
improves the energy yield of a solar collector. Unfavorable irradiation angles are given at diagonally incoming light
(azimuth angle) (no south adjustment of the mounting area, sun progress from east to west, diffuse irradiation).
e.g. direct sun exposure
e.g. diagonal, direct sun exposure
e.g. diffuse sun exposure

3Design and function of the collectors
Collecting box and heat transfer unit
The insulated collecting and distribution pipes are located inside the collecting box.
The advance or return connection can take place alternatively on the left of or on the right.
In each evacuated tube there is a U pipe with direct flow-through that is connected in such a way to the
collecting or distribution pipe that each individual evacuated tube exhibits the same hydraulic resistance.
This U pipe is pressed to the inside of the evacuated tube with the heat guide plate.

5. Heat output
The collector output is dependent on the efficiency of the collector ( ) as well as the irradiation intensity (G*)
and aperture surface per collector module (A). This determines the thermal energy output of the collector for a
given irradiation intensity. The following equation may be used to calculate the collector output:
whereby:
If the difference between the collector and ambient temperature ( ) is zero, there are no thermal losses
from the collector to the environment and the efficiency is at its maximum; this is referred to as the optical
efficiency .
A proportion of the solar irradiation (G*) on the collectors is "lost" due to reflection and absorption.
The optical efficiency takes these losses into account.
Heating of the collectors will cause them to transfer heat to the environment through conduction, radation and
convection. Heat transmission coefficients a1 and a2 take these losses into account.
The output curves are virtually horizontal. This means that CPC collectors in contrast with flat plate collectors
can still have a high output even when there is a large temperature difference between the collector and the
environment.

5Heat output
Solar irradiation values are low during the winter season and transitional periods (water heating as well as heating
support) (e.g. 400 W/m2 ). The temperature difference between the collector and the environment is also very high
due to the low outdoor temperatures.
The following tables (source: ITW test report no. 06COL513) precisely depict how the collector output varies
depending on the irradiation intensity and temperature difference. The stated values are for vertical irradiation
angles.

6Configuration of the collector area
6. Configuration of the collector area
For the accurate design of a solar plant, the following parameters must mandatory be known:
• for solar plants for water heating: warm water requirements, user behavior, consumption profile, etc.
• for solar plants supportive of heating, additionally: heat requirements, heating surface design temperatures, etc.
In the majority of all cases, these are not fully known.
Therefore, the specifications in the following 2 tables are to be regarded as recommended approximate values
which in individual cases may be exceeded or fallen below by up to 25%, depending upon customer request
(comfort, costs).
Furthermore, the specifications were based upon the assumption of an approximate adjustment of the collector
field towards the south and a roof pitch between 25° and 50° at the location of Würzburg, Germany.
With deviating boundary conditions, a detailed design with simulation programs is recommended.

7Notes on solar controllers
7. Notes on solar controllers
Solar controllers for evacuated tube collector systems should include a "boost function". This "boost function"
prevents an excessively high temperature difference between the temperature measured by the collector sensor
and the temperature in the lower/centre part of the pipes. When the collector sensor recognises a temperaturerise, the "boosting" (switching on) of the pump should occur two to three times per minute for ca. 3-5 seconds
to feed the hot solar fluid to the measurement point.

8Configuration of the collector connecting pipes
8. Configuration of the collector connecting pipes
For the dimensioning of the pipes, a medium throughput of approx. 30 - 40 l/h m2 aperture area
(approx. 0.5 - 0.7 l/min m2 ) can be assumed. In particular with large solar plants, we recommend „low-flow“
operation where the specific flow rate can be reduced to approx.12 - 18 l/h m2
(approx. 0.2 - 0.3 l/min m2
).For the reduction of the pipe work requirements, we recommend a series connection of max. 9.0 m2 (high-flow)
and 14 m2 (low-flow) collector aperture area.
In order to keep the pressure drop due to the pipe system of the solar plants as low as possible, the flow velocity
in the copper pipe should not exceed 1 m/s. We recommend flow velocities between 0.3 and 0.5 m/s. The cross
sections are to be dimensioned as with conventional heating equipment according to throughput and speed.
For the installation of the collectors we recommend commercially available normal copper pipe and gunmetal
fittings. Due to the high standstill temperatures, the junction points of the pipe lines should be hard soldered or
connected with clamping ring screw connections.
Galvanized pipes, galvanized pipe fittings, and graphitized gaskets should not be used. Hemp is to be used only
in connection with pressure and temperature resistant sealant. All components used must be resistant against
the heat distribution medium.
The thermal insulation of pipe lines in external areas must be temperature and UV radiation resistant as well as
resistant against bird pecking.

9Configuration of the expansion vessel size
9. Configuration of the expansion vessel size
Design fundamentals for the determination of the expansion vessel size
The following formulas as indicated are based on a safety valve of 6 bar. For the accurate calculation of the
expansion vessel size, first the volume contents of the following components must be determined in order toafterwards be able to calculate the vessel size with the following formula.
Formula: V nominal (V unit · 0.1 + V vapor · 1.25) · 4.8
Vnominal = nominal size of the expansion vessel
Vunit = contents of the total solar circuit
Vvapor = contents of the collectors and pipe lines that are situated in the vapor area
Example for the determination of the individual volumes:
Specification: 2 collectors CPC 12 OEM / INOXPipe line: Cu 15 mm, 2 x 15 m length
Static height H: 9 m
Contents of the reservoir heat exchanger and the solar station: e.g., 6.4 l
Pipe lines within the vapor area: Cu pipe 15 mm, 2 x 2 m
You can determine the individual contents of the equipment components from the respective data tables of the
product description. On the following page, the contents of the usual sizes of Cu pipe lines and contents of the
CPC tube collectors are indicated.
Vunit = contents of: Heat exchanger of the reservoir + pipe lines + collectors
= 6.4 l + 30 m · 0.133 l/m + 2 · 1.6 l = 13.59 l
Pipe lines above or on the same level of the collector collecting box (with several collectors one above the other,
the lowest collecting box applies) can be filled with vapor during standstill of the solar plant. Thus, the contents
of the concerned pipe lines and of the collectors are comprised in the steam volume Vvapor.
Vvapor = 2 · 1.6 l + 4 m · 0.133 l/m = 3.73 l
(contents of 2 x CPC 12 OEM / INOX + 4 m pipe Cu 15 mm)
Calculation of the expansion vessel size:
Vnominal (Vunit · 0.1 + Vvapor · 1.25) · 4.8
Vnominal (13.59 l · 0.1 + 3.73 l · 1.25) · 4.8 = 28.90 l
Selected expansion vessel: 35 l
Determination of contents of the unit, primary pressure, and operating pressure:
For the determination of the required amount of solar fluid, the feed of the corresponding expansion vessel must
be added to the unit contents.
The feed in the expansion vessel results from filling the solar plant from the primary pressure to the operating
pressure (dependent on the static height „H“). The following table shows the percentage of the feed, based the
selected vessel nominal size, and the pressure specifications.
With a static height of 9 m, the following applies (see table on the following page):
Vfeed = Vnominal · 12.5 % = 35 l · 0.125 = 4.4 l
