Buying the right solar street light could be a difficult decision as there is a lot to choose from and there is no much information online in terms of the specifications of lights available in India. Usually, unless you call a solar lights dealer, you do not get configuration or pricing of the lights. To make the job easy, a few options are given below to select a good light as per your needs.
Consider the following factors before you choose a solar street light:
- How much area would you like to illuminate?
- Which solar street light is the best for areas with people movement?
- Will the lights be installed in a remote area?
- Are the lights for public or private use?
- Is the requirement of solar street lights for decorative or security purpose?
- Are the lights maintenance-free?
It is recommended that you use solar street lights with lithium-ion or lithium ion phosphate (LiFePO4) batteries as they are more durable and efficient when compared to traditional lead acid batteries. All-In-One solar street lights with motion sensor can be used in remote areas as the people movement is less in such areas. Integrated solar street lights with intelligent sensor are a better choice for public places like streets, parking lots and gardens where the lights give 100% brightness for first four hours and then change to a lesser brightness to ensure whole night illumination. For areas where there is active people or vehicular movement throughout the night, you may use those integrated solar street lights which provide continuous 100% brightness for first four hours and then reduce its brightness to ensure whole night illumination.
Depending on the area to cover and the purpose of installation, you may choose the LED wattage. All the solar street lights detailed here use MPPT or PWM controllers and have IP65 waterproofing to withstand harsh climatic conditions. The lights have durable metal or ABS plastic body and require less to no maintenance after installation. All the lights are charged using purely solar energy. They operate automatically from dusk to dawn and some have intelligent motion control options.
