Frequently Asked Questions
HOW DO SELS SOLAR LIGHTS WORK?
During the day, SELS solar lights receive sunlight directly from the sun’s beams. The UV rays strike the solar panel and are converted to energy. This energy is stored in the integral battery system.
At night, when no light is detected, the power management system triggers the battery to power on the system loads, producing a powerful LED output bright enough to light residential areas, parks, streets and other recreational areas.
IS SOLAR POWER A NEW TECHNOLOGY? ARE THERE STILL THINGS THAT NEED TO BE WORKED OUT?
The Photovoltaic Effect was discovered in 1839 making it a technology that’s been around for a really long time. At SELS we develop and capitalize on the industry’s latest improvements in solar energy generation. We want our brand to be associated with excellence, so we ensure our products offer the highest performance technology available including our solar panels, batteries, LED chips, drivers, rust protection, and more.
WHY DO SELS SOLAR LIGHTS USE LiFePO4 LITHIUM BATTERIES?
LiFePO4 batteries have a lifespan ten times longer than that of traditional lead acid batteries, dramatically reducing the need for battery changes. They operate with much lower resistance and consequently recharge at a faster rate. They are lighter than lead-acid batteries, usually weighing about 1/3 of the total weight.
LiFePO4 offers about twice the battery capacity in the same amount of space (compared to leadacid). With operating ranges from -40 to 160 degrees Fahrenheit, LiFePO4 batteries can handle tremendous variation in temperature. Lithium iron phosphate batteries are also more environmentally friendly and safer for use in any system.
Other advantages of LiFePO4 technology include upper and lower voltage protection, dead short and reverse polarity protection, and a flame-retardant chemistry.
HOW LONG WILL MY SOLAR LIGHT STAY ON?
SELS’ solar lights will stay on as long as you need them, and never when you don’t. We can fully customize the output to operate in any manner you need, including automatic dimming infrared occupancy sensors, pre-programmed run times, or a range of other options. As a base, our systems have power storage capacity to stay on for over 3 days.
WHAT HAPPENS WHEN IT IS CLOUDY, RAINY OR SNOWING?
No need to worry. Your solar panel will continue to charge the battery at a reduced rate even when it is cloudy or rainy, meaning the light will still turn on as long as the solar panel is not completely covered and receives some amount of sunlight.
Additionally, the system’s battery reserve is designed to outlast adverse weather events.
HOW DOES THE SELS LIGHT KNOW WHEN TO TURN ON AND OFF?
For our Solar Garden Lights, and some of our Park Lights, the solar controller uses the voltage of the solar panel to sense the onset of darkness to control when the system turns ON and OFF. When the system detects darkness it turns ON and when it detects light it turns OFF.
Our Street Lights and a few of our Park Lights can be programed by remote control to turn on and off at the hour you choose. You can also program the percentage of light you would like turned on at different times. For example, you might choose to have the light turn on at 8pm at 100% power until midnight, and then have the power reduce to 50% until switch off at 7am.
For larger scale projects, you can choose to have our centralized remote monitoring system, allowing you to control your lights from a computer or your mobile device.
HOW DIFFICULT IS THE ASSEMBLY OF SELS SOLAR LIGHTS?
Our SELS Garden Lights require no assembly. There is a manual power switch located in the base of these units and needs to be turned on only once to activate your lamp.
Our Solar Park Lights require minimal assembly which includes anywhere between 2 to 4 screws.
For our larger models, a two-person assembly is required because of the weight of poles and parts. However, the assembly requires only a 4 to 8 step process depending on the model.
Having an easy to assemble product is just as important to us as the quality of our products, so we made sure to make our lamps as user friendly as possible.
DO SELS SOLAR LIGHTS COME WITH ANY WARRANTIES?
Yes, we offer an all-inclusive warranty of 5 years on many of our products.
CAN I BUY A REPLACEMENT BATTERY FROM SELS?
Yes, we carry stock of replacement batteries, solar panels, and other parts in the event of damage. We have you covered.
CAN SOLAR POWER REALLY RUN CAMERAS, DEVICE CHARGING, AND COMMUNICATION EQUIPMENT THAT IS RUNNING ALL DAY AND ALL NIGHT THE SAME WAY THE LIGHTING WORKS?
We design our charging stations, surveillance systems, and connectivity stations to the same rigorous standards as our lighting products. Surveillance equipment, device charging, and communication equipment must operate without interruption in order to make sense, so we emphasize reliability and performance based on project location and system loads specified by the customer.
