Solar modules convert solar energy into electrical energy. The latter is stored in the battery. At dawn solar modules stop producing energy (no current), the controller realizes that it is dark and turns the light on. The light is turned off as soon as solar modules start producing energy in the morning.
All photinus luminaires operate for 75 to 100 hours with full batteries.The controller stops current supply to the LED as soon as the capacity of the battery gets lower than 30% (remaining capacity) in order to secure the battery from a deep discharge.
We suggest to clean the solar module and the LED module once a year. Battery has to be replaced every five years.LEDs have a life span of 12 years.
Average installation time is 20-30 minutes per luminaire.
The battery has to be replaced every five years. The reason therefore is, that the remaining capacity is too low to guarantee a satisfying operation (expecially in winter). Every technician is able to change the battery.
You can return your battery directly to photinus. The German foundation “Gemeinsames Rücknahmesystem Batterien” provides container to trader, townships and all public entities for the returning of batteries. This is free of charge. ERA-ELektroRecyclingAustria provides this service in Austria. 95% of all lead-gel batteries are recycled.
Battery: 5-8 years (depending on battery model), LED 12 years, PV-Modul 20-25 years, Pole & casing 30 years
According to official norms solar luminaires can illuminate minor and residential roads at less than 30 km/h. These are especially the S-classes according to DIN EN13201. In addition, all walk- and bicyle ways can be illuminated according to official norms.
If needed, motion sensors can be applied to all photinus luminaires in order to turn the luminaires on and off. Please consider that the range of available motion sensors is limited to 10 meters.
A decade of expercience with solar lighting tought us, that we need a relation of 10:1 between the PV performance and the LED performance. One can ensure operation in Middle Europe during winter only under these circumstances. This means: 300W PV performance equals 30W lighting performance Photinus solutions range between 3-30 W lighting performance and between some 300 – 3000 lm luminous flux. Be aware, that some competitor use values of summer operation in their data sheets.
Photinus energy towers are designed vertically, hence it is not possible that snow remains on the solar modules. Due to the increased total radiation through reflection the radiation to the solar luminaire is even higher at snowy conditions.
Yes. Solar luminaries already work above the 48. latitude for a number of years. Photinus luminaires operate successfully in Moscow (55. latitude). Nevertheless, it is not possible to use any luminaire at any place on earth.
Luminaires are either fixed by using a screw fundament (Krinner) or by using a traditional concrete pipe.
