Why 1OO % transparency?With a solar energy system, anybody can produce environmentally friendly electricity – that s great! Things become a litt le more complicated when one of the modules is not working properly. Unfortunately, this happens very easily for a number of reasons: birdies dropping their business, trees and leaves casti ng shadow or martens chewing on cables. SunSniff er® identi fi es these problems. Plants with SunSniff er® inside harvest between 6,5 % and 17,5 % more energy depending on the locati on and diff erent factors.

The biggest impact on yield of your pv plant are the external eff ects. To correct them you fi rst need to identi fy the opti mizati on potenti al. Predicti ons for future opti mizati ons are almost impossible. Highest resoluti on is required for professional off -site error detecti on and reduced O & M cost.
Polluti onSoot from exhaust fumes, dust and pollen sett le on the surface of the module. As a result, light can no longer reach the cells.
WeatherExtreme temperatures, high snow levels and hail can lead to glass breakage.
AnimalsMartens chew through cables at night; birds soil modules with droppings.
Installati on errorsModules can be setup incorrectly and plugs forgott en; erroneous connecti ons can cause a dangerous electrical arc.
Producti on defectsSoldered connecti ons become britt le causing hot spots; performance tolerances are not complied with.
Due to the serial connecti on of modules in a string, the maximum current fl ow is limited to the fl ow of the weakest module.
Therefore one single faulty module also aff ects the performance of the good modules in a string. SunSniff er® recognizes and locates defects immediately and for each individual module. We call that 100 % transparency. Regular maintenance and cost-intensive roof in-specti ons can be avoided. The system also shows when, where and what needs to be done.

That‘s how SunSniffer® worksBrilliantly simple - simply brilliant
The SunSniff er® system consists of three parts:
The SunSniff er® SensorThe small sensor is integrated directly into the modules juncti onbox. It measures voltage and temperature and sends the informati on att ached to the modules serial number to the string server through the existi ng cable.
The SunSniff er® String-ServerThe String-Server reads the module data from the strings and measures the current and voltage. For every string you need a String-Server which sends the read data to the Connecti on Box. We have String-Servers for one and two strings for a more convenient installati on.
The SunSniff er® Connecti on BoxThe Connecti on Box receives the data from every String-Server and sends via any desired router (e.g. for UMTS, DSL) to the webserver.
The SunSniff er® WebportalThe Webportal analyses and edits the data for the user. The SunSniff er® Webportal does not only detect individual performance variati ons but can also analyse certain patt erns like shading of a module by using intelligent data analysis.
SunSniff er® powerline technologySensor and server communicate over the normal solar cabling using a specifi cally de-veloped transmission technology. An additi onal installati on of communicati on cables is therefore not necessary.
Special functi ons
Intelligent warning systemThe warning system within the SunSniff er® Webportal recognizes performance variati ons of every component on a percentage basis. Besides this simple recogniti on it also detects data patt erns by automati c data analysis. For example a moving shadow or snow on the modules can be detected. A warning will be sent via e-mail in case of a problem.
Fast & exact localizati onBy using the SunSniff er® PlantView you can show the plant on the SunSniff er® Webportal the way it was built. This functi on enables a focused course of acti on in future maintenance or repair.
Version for mobile devicesWith an easy and clear version of the SunSniff er® Webportal for your mobile devices you can always have one eye on your revenue and can check the operability of the plant at any ti me.
Representati ve illustrati onsVisualize your ongoing commitment via diff erent presentati on modes and show it via any screen with an internet connecti on.
Did you know?
According to the Associati on for the Promoti on of Solar Power (Solar-Förderverein), one should budget about 1 % of the original price for maintenance per year. With SunSniff er® you can reduce these costs by up to 30 %.

How SunSniffer® solves pv plant pro-blemsTake a look at the SunSniff er arti fi cial intelligence and how it is detecti ng problems, analy-zing the causes and is therefore opti mizing your plant!
Detecti on of defecti ve modules
A defecti ve module is detected and directly compared to its neighbouring ones. A yearly loss of 112 € is calculated directly so you can see, when it will be profi table to do the on site maintenance.
Detecti on of moving shadows
A moving shadow with a yearly loss of 59 € is detected. Especially two modules (yellow and green line) are aff ected by this. The cause for this can be located on the next on site service.

Exact localizati on of each module and every string
The SunSniff er not only detects and calculates the loss of the defecti ve modules, but they are localized exactly via the SunSniff er PlantView. You are able to see each module with its power output, its string and inverter number and locati on on the rooft op. Therefore a service technician is able to fi nd the modules easily.
Examples of problems detected by SunSniff er®
Problem: A tree is casti ng a shadow on diff erent modules.Eff ect: The power output of the module is decreased by 20 %. Therefore the inverter has a power loss of 1.5 %, with a yearly loss of 51 € for the plant.Soluti on: With SunSniff er the moving shadows can be detected and the prob-lem may be resolved at the next on-site maintenance.
Problem: The glass of one module is broken by hail.Eff ect: The power of this specifi c module is decreased by 40 %. Therefore the inverter has a power loss of 3 % with a yearly loss of 102 € for the plant.Soluti on: SunSniff er detects the loss and localizes exactly which module is aff ected.

Technology preview
SunSniffer® Secure
SunSniffer® Secure considerably reduces the risk in case of fireUsing SunSniffer® Secure allows an emergency shutdown of each individual module.
• Fires can be extinguished without any precautionary measures and without putting the fire fighters at risk.• Due to temperature monitoring and emergency shutdown directly in the junction box modules can be switched off in case of a possible overheating.
That‘s how SunSniffer® Secure worksSunSniffer® Secure is an optional extension of the SunSniffer® Monitoring System. Swit-ching off is performed by the SunSniffer® Secure sensor. The sensor is integrated in the junction box of the module. In case of emergency the electrical current is cut off at its origin. The shutdown signal is sent from SunSniffer® Server to the SunSniffer® sensors. Switching off can be triggered by the software or using a manual switch. Prior to the execution Sun-Sniffer® Secure confirms the shutdown. The transmission of the signal is carried through the normal DC cabling, additional cabling serving as communication lines is not necessary.

High risk of fi reIn case of emergency photovoltaic modules pose a high risk for untrained fi re fi ghters as long as electricity fl ows.Current practi ce is that a DC switch is installed in front of the inverter, which allows the plant to be switched on and off . The problem is that electricity conti nues to run through the modules and cables on the roof.
Advantages over competi tors• Cost-eff ecti ve emergency shutdown soluti on directly in the juncti on box and • Profi tability of the plants remains guaranteed• No additi onal cabling• Standard certi fi ed juncti on boxes are available for a quick integrati on by module manufacturers
Benefi ts • Makes the fi re department’s job easier and less risky• Sati sfi es the demands of the fi re department• Complies with liability provisions and safety regulati ons, required for certain type of plants and countries
