Frequently Asked Questions
Battery fundamentals and basic terms
What is open circuit voltage?
What is nominal voltage?
What are the differences between primary and secondary batteries?
What is battery internal resistance?
Municipal and Public Infrastructure
How do solar streetlights perform in extreme weather conditions?
Solar streetlights are designed to withstand harsh environments, including high winds, heavy rain, snow, and extreme temperatures. Our products are IP65-rated for waterproofing and are built with corrosion-resistant materials.
Battery and Analysis
What are the possible causes of zero or low voltage in a battery pack?
2) The plug is short-circuited, broken, or poorly connected to the plug;
3) The leads are desoldered and soldered to the battery;
4) The internal connection of the battery is incorrect, and there is missing, weak, or desoldering between the connecting piece and the battery;
5) The internal electronic components of the battery are incorrectly connected and damaged.
What are the characteristics of rechargeable portable batteries?
There are rechargeable portable batteries in different electrochemical types, such as lead-acid type (2V/unit), nickel-cadmium type (1.2V/unit), nickel-hydrogen type (1.2V/unit), lithium-ion battery (3.6V/unit) ), the typical characteristic of these types of batteries is that they have a relatively constant discharge voltage (there is a voltage platform during discharge), and the voltage decays quickly at the beginning and end of discharge.
Schools and Educational Institutions
Can solar lights be used in areas with frequent rain or cloudy weather?
Yes, our solar lights are equipped with high-efficiency solar panels that can still charge even under cloudy or rainy conditions, although performance may be slightly reduced compared to sunny days.
Transportation and Highways
What maintenance is required for highway solar lighting systems?
Routine maintenance includes cleaning the solar panels, checking the battery status, and inspecting the light fixtures every 6-12 months.
How do you ensure the lights remain theft-proof in high-risk areas?
We use tamper-resistant hardware, anti-theft bolts, and GPS tracking technology to safeguard the solar lighting systems.
Public Gardens and Landscape Lighting
How long do solar-powered lights last in public spaces?
Our solar-powered lights are designed for durability and long-term use. The lights typically last for 5-10 years, depending on the quality of the solar panels and the local climate conditions. The batteries last around 2-3 years and can be replaced easily.
Battery Types and Applications
How to classify batteries?
Primary batteries: carbon-zinc dry batteries, alkaline- manganese batteries,lithium batteries, activated batteries, zinc-mercury batteries, cadmium-mercury batteries, zinc-air batteries, zinc-silver batteries and solid electrolyte batteries (silver-iodine batteries) etc.
Secondary batteries: lead batteries, Ni-Cd batteries, Ni-MH batteries, Li-ion batteries and sodium-sulfur batteries, etc.
Other batteries: fuel cell batteries, air batteries, thin batteries, light batteries, nano batteries, etc.
