Solar power for independent industrial goods, devices, instruments, island systems, off-grid-systems and stand-alone systems.

A multitude of products and devices have to be supplied with electricity independent of the grid. Either there is no grid connection available or the connection is too expensive and extravagantly. On top of that there are over two billion people on the earth without access to the regular grid.

But without electricity many modern devices don’t work. Ticket machines, illumination as well as the communication in its function from mobile to internet only works on the basis of a reliable power source. SOLARA solar panels and complete stand-alone systems can provide the power necessary. SOLARA has high quality and affordable solutions for solar electrification. We have independent solar electricity for locations without the needed power connection or in remote areas.

Many important applications - safely and reliably supplied with solar power!


The following are examples for commercial use of solar energy

Solar application explained and illustrated in detail on this page:

Car2X or car-to-infrastructure powered by solar power are the future in modern mobility. The communicating vehicles need an appropriate infrastructure in cities and municipalities that can be supplied with solar power regardless of location.

 

 

Traffic lights can also be equipped with solar systems for this purpose so that they can communicate with cars in the future.

Communication between traffic lights and vehicles powered by solar power is independent of an electrical infrastructure. The traffic light systems are equipped with solar WiFi hotspots and are connected to a traffic control center. This solar-powered technology is called V2X, where V stands for vehicle, and X for different devices or facilities. Via V2X, traffic lights can send data to cars via solar WiFi hotspots and also receive data via WiFi from vehicles. In addition, solar traffic lights send data to the so-called "mobility data marketplace", which contains all information about traffic jams, construction sites, traffic flows and provides much more.

Energy-efficient LED variable message signs equipped with solar systems enable road users to receive current traffic information on motorways and all other roads. Traffic signs and speed indicators equipped with solar cells help to prevent accidents and to positively influence the flow of traffic. Lanes can be flexibly displayed and changed with solar. Dynamic solar route information boards with a small solar system can display alternative routes at any location in the event of traffic jams or roadblocks. Measuring devices with solar cells as weigh-in-motion (weighing vehicles while driving) can also be used at locations without a power connection to monitor overloaded trucks.

Measurement technology is important in every aspect and is now mainly digital. Therefore it must exist a power supply. A solar system is the perfect solution for independent power supply.

 

For the environmental areas of air, noise and water, routine measurements have to be performed, often operated with solar power. Solar systems are designed to ensure that measurements of air, noise and water quality can be continuously monitored. The independent power supply enables measures to secure and improve the media. Solar measuring devices for emission and immission measurements relating to air are carried out for the measuring tasks in a special procedure. It serves to comply with and monitor the air pollution control regulations. Such solar measurements can detect air pollution at the point of its origin (emission) and at its place of action (immission) because the solar panels ensure a safe and independent power supply at every location.

Equip emission measuring devices with solar to detect noise, fine dust and sources of danger on site. With professional solar systems from SOLARA, measuring devices can reliably record and store all data.

 

It is essential to prevent harmful substances, noise, fine dust and harmful radiation. For this reason, emission values must be observed. But this can only be measured on site. Solar modules provide the necessary power for this even if no power connection can be used directly. This also applies to gas leaks, light sources and suspended matter. Inaccurate measurement results due to measuring points that are too far away or an unreliable power supply can be a disaster. Only with solar energy you can be on the safe side and be up to date to generate professional data.

Appropriate measurement technology is absolutely necessary to determine different physical quantities. Measurement technology is indispensable for automation today. In production, measurement and test data are necessary for the quality of a product. Therefore sophisticated measurement technology has an overarching effect.

 

To achieve this, modern measurement technology must always work reliably. Therefore it is sensible to use self-sufficient solar systems to ensure reliable measurements at all times.

The measurement technology supplied with solar power today is used for the following processes:

 

Production process, product quality in one production at the incoming inspection, intermediate inspection and outgoing inspection.

The test technology supplied with solar system includes material testing, dimensional testing and functional testing

When it comes to measuring technology with solar panels for material testing, the focus is on material quality testing technology in quality assurance. A distinction is made between destructive material testing and non-destructive material testing. In the destructive material test a specimen is examined e.g. with the following properties: tensile strength, yield strength, bending strength, hardness, toughness and chemical composition.

 

Electrical conductivity also plays a role for measurement technology with solar power supply in plastics processing.

 

Professional measurements of the measured values quickly, precisely and galvanically isolated, as well as being intelligently preprocessed or monitored, are often location-independent. Such smart data and industrial analytics, or measurement technology as an interface to the virtual world, can ideally be safely and reliably supplied with electricity using solar cells or small solar systems.

 

In contrast to the earlier imprecise, manual and tedious handling, measurement technology with solar panels is now compact in construction, absolutely precise and with quick measurement and is easy to maintain. Independent and automated data transfers to a central EDP system are possible at any time through the solar system. The connection to a powerful IT or EDP network is the basis of today's measurement technology. The central recording of the measured values, central administration and processing is indispensable today. A high-performance solar system and solar cells with a high degree of efficiency guarantee such quality concepts.

Cellular networks with solar panels and a WiFi hotspot make the internet wireless. Powerful WiFi mesh networks can be installed anywhere thanks to integrated solar panels or solar cells. They are ideal for public outdoors WiFi networks, in the city or in the country. A mobile WiFi hotspot, e.g. at events such as concerts, sports and games is easily possible with solar power. Locations without a network or internet connection are a thing of the past thanks to solar systems. The future belongs to the fully self-sufficient WiFi hotspot with solar panels. This solar WiFi hotspot can be connected to an existing internet connection via WiFi or LAN. In addition, the solar WiFi hotspot can also be useful as a range extender for extended range coverage. Places without access to an existing internet connection can be equipped with the latest mobile (5G, 4G, etc.) cell phone routers through the solar mobile radio network and the solar WiFi access point.

Just sitting on benches used to be. Today you also want to surf the internet or charge your cell phone - solar energy makes it possible. Solar panels integrated in park benches generate the necessary electricity. The park bench also provides free WiFi. Some may also call them WiFi benches. The smart benches only work with solar power. Integrated photovoltaic panels charge the built-in battery so that power is always available for the USB connection and the WiFi. USB ports built into the WiFi bench enable cell phones, tablets and much more to charge. Inductive charging, i.e. charging without cables can also be possible. Those who want to surf the internet via WiFi can comfortably linger in the green on the solar bench in the future.

Emergency telephone with solar energy

An Emergency telephone is basically a telephone installation. The Phone is for making calls to emergency services to ask for help. It is mostly required in a place of special danger or isolated places. E.g. in parks, in the woods, on the beach and at the highway. At the majority of these places there will not be any connection for power supply, it lend itself to consider a solar power plant for a stand-alone power supply.

 

 

The supply of the emergency telephone with solar power is a fulsome technology and is often already being implemented. Well-known manufacturers offer suitable emergency telephones. For the power supply of the emergency telephones SOLARA solar panels are often used, as SOLARA produces absolutely reliable, robust and long-living solar panels. For example, the SOLARA M-series, without glass cover, is ideal for public areas, as glass damage due to vandalism is excluded.

 

 

The emergency telephone also operated with solar power is technically a so-called "special means of communication". Modern emergency telephones are connected via ISDN, IP-telephony (Ethernet) or GSM with an emergency call center or making contact with them if necessary.

 

New emergency telephones also transmit the location of the telephone through the call. With solar power a so-called polling, the accessibility of the emergency telephone can be checked. Polling is a regular request for the functionality of the emergency telephone and the solar power supply.

 

The current emergency telephones are usually equipped with an automatic function-control. The emergency telephones check themselves, as well as the speaker and the microphone. The amplification is set automatically and adapted itself to the environment. Signals or lights on the, emergency call button and the emergency telephone are always supplied with reliable solar power in every season.

 

Wherever there is neither a power connection nor a fixed line telephone network, the emergency call is made on GSM-basis. This is no longer a temporary solution on construction sites and in remote regions. Solar power with solar power plants from SOLARA is ideal for GSM-emergency telephones.

 

More and more emergency telephones are equipped with voice-over-IP-technology nowadays. The relatively high energy requirements of VoIP-emergency telephones or of the network components can be perfectly covered by the solar technology from SOLARA.

 

In conclusion, with SOLARA’s solar panels emergency telephones can also be reliably operated away from highways and urban areas without a power and telephone cable connection. In addition, nowadays the solar power supply is cheaper than a power connection and it does not incur any basic charges and power consumption costs.


Solar facades for buildings

Even a facade can gain power. Many think in terms of solar power generation on systems on the roof or even open space. Solar panels can also be mounted on the exterior walls of a building. The so-called curtain wall not only produces solar power but also protects the surface of the building. Nowadays solar panels have a life expectancy of up to 40 years. A variety of weather conditions can bear up solar panels.

 

 

Due to the vertical installation or orientation of the solar panels the low sun will be used in particular. Especially in the winter months the solar yield is thus optimized.

 

 

Here is an example of a beautiful solar facade in the center of Cologne, which has been producing reliable solar power for many years.


The SOLARA stand-alone systems for devices without a power connection

SOLARA is specialized in custom off-grid-solutions for many different needs and uses. Those complex systems have, in addition to the solar panels, a charge regulator and an inverter. This way it is possible to store the solar energie locally in batteries and supply the device with 12 Volts DC or 230 Volts AC.

 

SOLARA-QUALITY SINCE 20 years

 

Solar modules, components and complete systems by SOLARA are used everywhere there is no reliable power source. In remote areas of the world, on the sea, in technical facilities, in traffic control systems and in telecommunication systems.


Stand-alone-systems by SOLARA are constructed in such a way, that they can withstand the highest climatically stress. They are robust, flexible in use conditions and use the provided sunlight even in unfavorable conditions optimally for energy production.

 

To ensure the quality and efficiency of the SOLARA products, the modules and mounting systems are produced in Germany. Each solar panel is tested and certified with strict quality standarts by ISO conditions. After completion each solar panel is measured individually under international recognized STC conditions and gets a unique and unchangeable serial number.

Radio stations with solar power

A radio station can be a transmitter, receiver, or both in one and is for example detectable by an antenna. Furthermore special additional facilities have to be included to maintain a radio service.

 

The most important additional equipment in remote areas is the solar power supply with a solar power plant. A radio system is operated electrically and depending on the power of the radio waves, duration of wireless communication etc., needs a reliable solar power supply.

 

SOLARA offers a variety of different solar power plants for this purpose.

According to their use a distinction is drawn between solar powered radio stations as follows:

Main radio station, sub radio station, receiving radio station, transmitter radio station, etc. with or without solar system. The ITU (International Telecommunication Union) defines the internationally binding categorization of different radio stations. Whereat the solar power plant is irrelevant.

 

In Germany, the Federal Network Agency holds the frequency management. To operate a radio station it requires an official approval, but not for the solar power plants. Usually the approval of the radio station in Germany is issued with a frequency allocation by the Federal Network Agency, according to the Telecommunications Act.

Various radio stations (selection) which are also supplied with solar power:

Rescue radio station as emergency beacon according to the ITU "a mobile station of the mobile maritime radio service or of the mobile aeronautical radio service which is used only for rescue purposes and which is on a lifeboat, life-raft or any other means of rescue". For more than 20 years solar power plants from SOLARA have been reliably supplied lifeboats with solar power.

 

Fixed radio-communication service is according to the ITU a "radio service between certain fixed points". E. g. beam radio, troposphere radio, embassy radio and private mobile radio. Solar power plants proffer in adjacent areas. In many cases the electricity connection, the basic charge and current electricity costs are more expensive than a solar power plant from SOLARA.

 

A fixed station (land station) is according to the ITU a radio station of the mobile service as a mobile land service, e. g. antennas of GSM-base station and GSM-transceiver. Here as well solar energy is often the first choice due to the greatly reduced costs for solar power plants.

 

According to the ITU, a radio beacon is a radio station of the navigation radio service whose signals enable a mobile radio station (e. g. in the aircraft) to determine its bearing or direction with respect to the beacon. Even small solar power plants can reliably provide the power supply yearlong.

 

In inland navigation the land station is a stationary radio station for inland navigation on land and the ship radio station is a mobile radio station for inland navigation on board an inland waterway vessel. The photos show the already common use of solar power plants for the power supply.

Electric pasture fences with solar panels

The fence is a border that should be strictly respected by animals. With a pasture fence animals can be fenced or kept away from surrounding land. The fence should be perceived as an insurmountable obstacle. An electric fence with solar power is ideal for this. Short yet harmless electric impulses have a deterrent effect on animals. The animals "learn" to accept the electric fence with solar power plants as an insurmountable limit. An outbreak is absolutely minimized. In remote pastures the supply of electric fence with solar power is without alternative.

 

Electric fences with solar power plants allow a continuous electrical voltage, but the circuit is closed only when the animal comes into contact with the solar powered pasture fence.

 

 

A solar pasture fence is easy to install and easy to modify and expand. The risk of injury from the pasture fence with solar power plants is practically excluded for humans and animals. With solar power through SOLARA solar power plants, a permanent and reliable demarcation of grazing animals is possible. The mobile solar power plants make the adaptation to the needs of animals of all kinds and the landscape conditions possible.

 

The Association of German Electrical Engineers in VDE 0667 has also presented the planning, installation and relevant safety regulations for electric fence with solar.

 

 

The solar electric fence is in many cases without alternative because the use of barbed wire due to the risk of injury to humans and animals is considered too large.

Solar power for the turnouts of the Harz narrow-gauge railway to the Brocken

After passing the station Goetheweg, at 956m altitude, the narrow-gauge railway goes directly to the Brocken. The points of the route are operated with solar power. In order to guarantee the necessary reliability it was decided to use solar panels from SOLARA. Made in the solar-power-factory Wismar, Mecklenburg-Vorpommern.

 

 

Before the train circling the chunks in a spiral 1½ times, every passenger can admire the SOLARA solar panels. On the 18.9 kilometer route to the Brocken railway station at 1,125m, the SOLARA solar panels "Made in Germany" always ensure safe operation of the points. Thanks to solar power with SOLARA solar technology, no expensive power supply had to be laid in the rough terrain on the Brocken.

History of the Brockenbahn

After the route was opened below the Brocken on June 20 1898, the opening of the remainder to the Brocken took place on October 4 1898. At that time all points had to be operated by hand since solar technology or even solar panels were completely unknown.

  

Until 1987 frequented freight trains on the track. It was transported mainly building materials, coal and oil, since no solar energy or solar panels were available. On the Brocken border troops of the GDR and soldiers of the Soviet Union were stationed, which were supplied by the railway. Since the route was in the restricted area since 1952 a pass was required to enter and the regular passenger traffic was shut down between Schierke and the Brocken.

In September 1991, the public transport was reopened with two steam-powered trains. There were first considerations for the use of solar energy with solar panels. The train operation is guaranteed since then by a Mallet-locomotive (1939 developed by Krupp prototype) and a new building of the German Reichsbahn.

 

The Brocken Railway was privatized in 1993 and has since been operated by the Harz Narrow Gauge Railways (HSB). A few years later, the points on the Brocken were electrified with solar panels by SOLARA from Wismar. High reliability of the solar power plants even in extreme weather conditions and the longevity of the solar panels were decisive for this decision.



Function and circuit diagram of a self-sufficient solar power system

We have systems for every need

In small performance range, reliability is also a crucial factor. It does not matter if it is a small shed in the mountains or a measuring station; often a small solar power plant is sufficient, even without complicated inverters, to have a secure poversource. Those small DC connected systems have the advantage that they are installed very fast and are easily portable, even with the ability to provide energy for light, radio, TV, cooling, etc...
On top of that is this equipment is the basis of complex systems. The, modular build gives the maximum of flexibility. Further components can be added in the future with growing needs.
