The solar powered lighting system for advertising light box offers a revolutionary concept for the outdoor advertising. It includes high efficiency solar panels, rechargeable valve-regulated lead-tin-calcium acid batteries, patented LED light modules, and lighting controller. This is a multifaceted product that has integrated these key elements into a single solution for off-grid application. Our solar ads light boxes enable users to place advertising on anyway where sunlight presence, without installing physical electric cable and paying monthly electricity bills. The conversion from the on-grid AC to off-grid solar DC power will reduce potential electrical hazards from lethal to harmless. It essentially combines the features of a regular advertising media light box and a solar energy input to create a cost-effective, safe and “green” solution offered in this turnkey product.
Our customize solutions, with its unique design, provides high quality and high uniformity back-light to the poster advertisement placed at the media location. The poster is illuminated by banks of LED (light emitting diodes) module sets positioned inside the light box. Each LED is improved with patented modifications to achieve optimum lighting results. We can customize to any sizes according to your outdoor adverstizing needs.

FREQUENTLY ASKED QUESTIONS
Question: For one full charge, without recharging again, how long will the system provide lighting?
Answer: It depends on the installation site of our system where the annual average daily sunshine hours may vary based on its latitude. Our design could provide sufficient power for operating from dusk to dawn. Different settings may be adjusted at the lighting controller. For example, on less sunny cities with extreme bad weather, you can change the timer setting to 6/off/2(6 hours operation upon dusk and 2 hours operation before dusk). Please contact our sales advisor for optimum setup procedures in your city.
Question: On installation, what is the tilting angle of the PV modules?
Answer: It is recommended to set the optimum tilting angle for optimum for winter when the short days and cloudy weather put the greatest strain on the system to meet the load requirements. The tilt angle in the winter is your installation latitude plus 15º. As a rule of thumb, the PV module should face true solar south if located in the Northern Hemisphere, and north if located in the Southern Hemisphere.
Question: How do you avoid vandalism?
Answer: The solar panels that our system utilizes are with tempered glass and Tedlar on the surface. This should be able to prevent common defacements.
Question: What’s the ideal operating temperature?
Answer: The ideal operating temperature is 25°C. The acceptable storage temperature ranges from -45°C to 70°C. The acceptable operating temperature ranges from -40°C to 70°C.
Question: What happens when the off-grid system (with Solar input) meets 3 or 4 days of overcast weather?
Answer: Our solar power system is specially designed to not only fit for each different installed location, but also would withstand minimum of 4 days without sun ray. Moreover, the system has a “smart control” chip built into each LED driver, in the leading LED of each chain. The smart control chip detects the drop of input voltage, or power reserve reduction due to lack of daily solar radiation, in the rechargeable batteries and adjusts the power output (dimming the lights) accordingly to perform more efficiently resulting in longer operation hour.
Question: Should we be aware of any hotspot issues?
Answer: If the sign faces are placed in the recommended optimum distance, there are no concerns for hotspots; these recommended distances are of traditional street furniture lightboxes. For those lightboxes with shallower depth, hotspots could occur but they are not as serious as in the case when using traditional fluorescent lamps and will become invisible when sign face is installed..
Question: Will shading affect the performance of PV modules?
Answer: PV modules are very sensitive to shading caused by tree branch, shadows from nearby building, or even bird dropping. Partial-shading even one cell of a 36-cell PV module will reduce its power output. Because all cells are connected in a series string, the weakest cell will bring the others down to its reduced power level.
Question: What’s the lifetime of the LEDs?
Answer: LEDs exhibit very long operational life characteristics, typically 50,000 hours or longer. Like all light sources, LEDs slowly decrease in light output over time.
