Solar Panels: The solar panel is one of the most important parts of a solar parking lot light, solar panel collects energy during the day, convert solar energy into electric energy that the light can use. There are two types of solar panels commonly used in solar parking lot lights: mono-crystalline and poly-crystalline. The conversion rate of mono-crystalline solar panels is much higher than their polycrystalline counterparts.
LED parking lot light: LED features energy-saving, the energy consumption of an LED fixture is at least 50% lower than the HPS fixture, LED fixtures are also less prone to failures with an average number of 50,000 working hours, whereas traditional parking lot lights range from 5,000 to 8,000 working hours with the much higher failure rate. So LED parking lot lights used as the primary light source of solar parking lot lights.
Rechargeable Battery: Battery is used to store the electric energy from the solar panel during the day, and provide energy for the LED parking lot light at the night. The capacity of the battery affects the backup days of the lights, and the life cycle of the battery is important to the lifespan of the light. Gel cell deep cycle batteries, lead-acid batteries, and absorbed glass mat (AGM) batteries are three types of batteries commonly used in solar power lights. Lithium-ion batteries are also popular nowadays, as they are compact in size, have a higher energy density, voltage capacity, and lower self-discharge rate.
Solar charge controller: Controller is the brain of the solar parking lot light. It’s a regulator, solar charge controller decides when to turn on or off the lighting, and when to charge the battery. When the battery is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off, it protects the battery from both overcharging and undercharging. There are mainly two types of solar charge controller:pulse-width modulation (PWM) and maximum power point tracking (MPPT).
Sensor: Using sensors are one of the best ways to lower the power needs of solar parking lot light. There are some types of sensors, such as dusk to dawn sensor, motion sensor, and so on.
Pole: For every solar parking lot light, a strong pole is essential. The solar panel, battery, LED light, and such all heavy components are mounted on top of it, and it should bear hurricanes in some areas. The pole should rust-resistant and durable enough to support long lifespan LED parking lot light and solar panel.
Interconnection cables: The solar panel, LED lights, solar charge controller, and battery are interconnected with cables. Cable size and lengths depend on the current that goes in the lights and the height of the pole.
The function of solar parking lot light depends on the quantity of above each component, the technology used in the system, and the management of lights. Choosing the right solar parking lot light is not an easy task, we have to know the system design and so many technical specifications. You need a professional and reliable supplier, which could design and choose a suitable component according to your requirement. Below are guides on how to choose components for the solar parking lot lights.
