Solar 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. Ether 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 acces 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 powersource. SOLARA solar pannels 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.

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 insolated 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 power plants are often used, as SOLARA produces absolutely reliable, robust and long-living solar power plants. 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 centre or making contact with them if necessary.


New emergency telephones also transmit during the call the location of the telephone. With solar power with 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 nowadays equipped with voice-over-IP-technology. 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 power plants emergency telephones can also be reliably operated away from highways and urban areas without a power and telephone cable connection. In addition, the solar power supply nowadays is cheaper than a power connection and it does not incur any basic charges and power consumption costs.

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 power plants

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 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 power plants 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. Solar power plants nowadays have a life expectancy of up to 40 years. A variety of weather conditions can bear up solar power plants.


Due to the vertical installation or orientation of the solar power plants 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 centre of Cologne, which has been producing reliable solar power for many years.

Solar power for the points 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.

We have equipment for any needs

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.

The SOLARA stand-alone-systems for equipment without grid 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.




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.

Custom solar panels for special uses by SOLARA

Custom build for stand-alone-systems by SOLARA. We have produced solar panels, for individual off-grid or island-systems, and tested with international standards on quality and a long life with experience of 20 years.
