FAQ – Solar street lights from Geo-Technik
What are the advantages of solar street lights over conventional street lights?
Solar street lights use solar energy to generate electricity, making them extremely energy-efficient and environmentally friendly. They help to reduce electricity costs and CO2 emissions. They are also independent of the power grid and ideal for remote areas without existing infrastructure. Installation costs are much lower than for conventional street lights, as no underground cables need to be laid.
How long do solar street lights last?
The service life of our solar street lights varies depending on the model and conditions of use. Thanks to the use of modern battery management-monitored LiFePo 4 batteries, the batteries have a service life of at least 8-10 years, which can be easily checked or replaced on most models via the mast service door. The LED street lights used have a service life of up to 50,000 hours, and the monocrystalline photovoltaic modules have a performance guarantee of 90% for 20 years. After purchasing a solar light, you have a 10-year spare parts availability guarantee. After this period, the light does not need to be dismantled if a component fails; we will of course continue to offer you equivalent replacement parts.
How does a solar street light work?
Solar street lights work by absorbing solar energy via solar panels during the day and storing it in a LiFePo 4 or Solar AGM battery. At night, this stored energy is used to power the street lighting. Our microprocessor controls switch the lighting on automatically when it gets dark and off again at sunrise. You can choose between 4 control principles:
- Switch on at sunrise. You can set 10 different time blocks after switching on and define a corresponding dimming level. The lighting switches off again at sunrise. (Example: 5 hours at 100% after sunset, then 50% light output for the rest of the night.
- Switch-on with motion detector. After sunset, the lighting switches to basic lighting as required (e.g., 10%). If a person is in the detection range of our motion detector, the lighting switches to 100% for a time you have predefined (e.g., 2 minutes).
- Switching on and off to the minute via a timer. The lighting only switches on at night at the times you have predefined. For example, for a bus stop or shift work. 17 switch-on times are possible. (Example for a bus stop: sunset to 10 p.m., then off and on again from 5 a.m. to sunrise)
- Manual activation via a push button. Here you have the option of switching on the lighting for an adjustable period of time (5 minutes to 3 hours) via an illuminated push button on the pole (stainless steel / vandal-proof, recessed in the door). Pressing the push button again switches the lighting off early if necessary. This solution is ideal for demand-based lighting such as small sports facilities, green waste collection points or collection points.
What applications are solar street lights suitable for?
Our solar street lights are ideal for use in parking lots, industrial areas, residential complexes, on bike paths, and in rural and hard-to-reach areas. They provide reliable lighting without the need for expensive power lines.
How much sunlight do solar street lights need to function properly?
Solar street lights require sufficient sunlight to fully charge the batteries. The location of the solar light should be chosen so that the PV module can be facing south and is illuminated by the sun for most of the day. As a rule, average sunlight is sufficient to operate the lights at night. Our models are specially developed and designed for use in Central European weather conditions. Features such as automatic lighting reduction by our solar control system when the battery is low ensure efficient and sufficient lighting even when the sky is cloudy and during the winter months.
Does Geo-Technik manufacture the solar street lights itself?
Yes, all of our solar street lights, brackets, and special solutions are developed and manufactured by Geo-Technik in Germany. Our in-house metalworking shop in Großkrotzenburg, Hesse, enables us to guarantee the highest quality standards and offer customized solutions for our customers.
How is a solar street light installed?
Installation is straightforward, as no wiring to the power grid is required. The solar street lights can be mounted in almost any sunny location. All components are pre-assembled by us
to keep assembly to a minimum. After installing the pole, the LED light head with pre-assembled bracket and cable is attached, and then the PV module is attached to the pole using the bracket that comes with the delivery.
Finally, the solar controller is connected (installed in the pole together with the battery). All our solar lights operate in the low-voltage safety range (below 60V/DC) and are electronically protected in multiple ways. You will also receive detailed, illustrated instructions for installation to help you install the lighting safely and efficiently. However, if you have any questions before, during, or after installation, our technical team will be happy to assist you.
Are the solar street lights weatherproof?
Yes, all our solar street lights are designed for outdoor use and are completely weatherproof. They are protected against rain, snow, and extreme temperatures and ensure long-term use even under difficult conditions.
How sustainable are solar street lights from Geo-Technik?
Solar street lights actively contribute to reducing energy consumption and CO2 emissions. By using renewable energies and durable materials, our products are a sustainable solution for public and private lighting projects. However, should a fault or damage occur, not everything needs to be replaced. In almost all cases, the affected components can be replaced or repaired.
What maintenance is required for solar street lights?
Solar street lights are basically maintenance-free. Occasional cleaning of the solar panels to remove dirt or snow and checking the battery about once a year are sufficient to ensure optimal performance. The history data of our controllers can be conveniently read out without tools using our programming device.
