Solar Street Light Automatic On Off

Forever-Lighting stand-alone solar street lighting systems create stored energy in the daytime by converting ultra violet light (sunlight) into power that is stored in the battery, which is then available to be used at night. The intelligent lighting controllers detect dusk, automatically turning the system on, and detects dawn, turning the system off,that's why solar street light automatic on off.There is also the ability to program the lights to dim.brighten. or turn off at certain times throughout the night.

A quality environmentally friendly solar LED light will have enough battery back-up (autonomy) to run the light for 2-5 full nights battery back-up, to ensure it will provide reliable light through prolonged poor weather.

Forever-Lighting consider all factors and stick to scientific data when designing a solar lighting systems: like shading factor,latitude,weather etc,especially based on the solar radiation and black data collected from NASA website which is very reliable.also considering solar radiation in Summer and in Winter.

► Design sheet for 6M pole 30w led solar street light

LED LAMP:30W power with Philips/Cree chip,super bright for solar led street light with pole

This led lamp is designed by experienced expert and controlled by strict quality system, integrate endurable structure and perfect design to keep its lifespan long, energy consumption low and costs down, meet a vast majority of challenging roadway and street lighting applications and optimize its lighting performance beyond the previous products.

SOALR PANEL:100W,mono-crystalline PV module with higher efficiency

Solar Panel takes an important rule in solar street light complete set,we use A+ grade solar cell to get higher efficiency 21.12% and adopt ultra white low-iron toughened glass with 98% light transmittance, which can resist hail stone and impact of ice and snow with max 5400Pa.

Factors (25% losses) have been applied to considering the dirty, power decay losses and angle losses in winter time.

IP68 junction box;aluminium frame tempered glass;Lifespan:20-25 years;Warranty:12 years.

SOALR PANEL BRACKET:3 types commonly used,customized is available

 

 

 

MPPT CONTROLLER:MPPT/PWM for optional(Hybrid type for hybrid solar street light is available )

Charge controller is the "CPU" of the solar led street lighting,we use famous brand SRNE charge controller,it's intelligent micro-computer controller,with automatic light and time control function,and priority of temperature compensation,over-charging/discharging protection,reverse-connection protection.

SOLLAR BATTERY:gelled/lead-acid type,and LifePO4/ternary lithium battery for option

Solar battery is one main key part in solar street lighting,it is related whole solar street light set lifespan,so we used extreme quality solar battery with higher cycle,higher energy density &fast recovery in deep cycle ,maintenance free,high pressure die cast spine grids ,proven cycling & deep cycling capacities etc advantages.

SOALR PANEL BRACKET:3 types commonly used,customized is available

STREET LIGHT POLE:3M-12M for optional

We have conical pole,octagonal pole,round pole etc for support solar light system for your alternative.

The street light pole material is hot-dip galvanized steel Q235,Q345,GR60 etc ;the surface is polymerized epoxy powder coated to prevent any corrosion, last >25 years.

The pole foundation is sized by project request and built to support high speed wind ＞160KM/H, even in the worst conditions.

ANCHOR BOLTS :optional

Anchor bolts buried underground by concrete make the whole solar street light set more strong.

The material of anchor bolts is engineering steel Q235,hot-dip galvanized/non galvanized for alternative,non galvanized.Folding anchor bolts to save the space is available.

PV CABLE (with MC4 connector optional)

 

 

 

 

We use quality cable reduces the power consumption wasted on components, optional MC4 connector make connection easy and durable.
