As the new year is approaching, solar street lights, as a representative of green energy, are becoming the first choice for urban and rural lighting. However, when it comes to choosing the right solar street light for your needs, we need to think more carefully. In this blog, we will provide you with a 2023 buying guide to help you choose the best solar street light manufacturer.
How to choose the right solar street light?
Ahead of the curve design and technological innovation
In the new year, ahead-of-the-curve design and technological innovation are important factors in choosing solar street lights. Focus on products that use the latest technology and smarter design, such as intelligent sensing and remote control features, to meet future lighting needs.
Durable Materials and Protective Designs
Solar street lights are outdoors all year round, so choosing durable materials and protective designs is crucial. Ensure that your product meets a high level of protection to withstand harsh weather and other environmental challenges.
Eco-friendly renewable battery technology
In 2023, environmentally conscious solar street lights will be more likely to use renewable battery technology. Choosing to use eco-friendly batteries reduces the impact on the environment and ensures a long lifespan for your streetlights.
Durability and Protection Rating
Considering the outdoor usage environment, ensure that you choose a product with a high waterproof rating and solid construction. Street lights that are waterproof can operate reliably in a variety of weather conditions, while designs with high durability will ensure that the product can be used for a long time in outdoor environments.
How to choose solar panels for solar street lights?
The price of solar technology has dropped dramatically in recent years, by more than 80 per cent since 2010. Making solar panels cheaper than ever. There are an increasing number of applications based on solar systems. Solar powered LED street lights are a popular application.
Choosing solar panels is not easy. We have to consider a number of factors: conversion efficiency, temperature coefficient, durability, etc.Monocrystalline silicon solar panels usually have a higher conversion efficiency than polycrystalline silicon. Monocrystalline silicon has a conversion rate of up to about 21 per cent, while polycrystalline silicon is about 18.5 per cent.
Monocrystalline panels ensures higher efficiency in energy utilisation. Temperature coefficient indicates the percentage decrease in panel efficiency when the temperature rises by one degree. The lower the temperature coefficient, the lower the performance loss of the panel in a high temperature environment. The low temperature coefficient is particularly important in solar streetlights, which are often used outdoors in hot environments.Choose panels made from high-quality materials to ensure that they can withstand wind, rain and other natural elements. Quality manufacturing and durability increase the life of the panels.
How to choose rechargeable batteries for solar street lights?
When choosing rechargeable batteries for solar street lights, different types of batteries have their own characteristics and applicable scenarios. Below are several common types of solar street light rechargeable batteries and their characteristics:
Lead-acid battery
Lead-acid batteries are a kind of traditional rechargeable batteries, which are divided into two types: open-circuit lead-acid batteries and closed lead-acid batteries (AGM, Gel). They have lower cost and reliable performance.
Scenarios: Suitable for application scenarios with limited budget and not particularly high performance requirements. Due to their relatively low energy density and lifespan, they may not be suitable for long cycle, high energy consumption applications.
Gel Battery
Gel batteries are also classified as closed lead-acid batteries with electrolyte in the form of gelatin fixed in a glass fibre separator layer. They have better deep cycle performance and longer life.
Scenario: Suitable for high-cycle charging and discharging scenarios, such as solar street lights that need to run frequently at night.
Deep Cycle Batteries
Deep cycle batteries are specifically designed for deep discharge and recharge with a robust cycle life and high energy density.
Scenario: Suitable for solar street light systems that require frequent deep cycling, such as those that need to operate normally in cloudy and rainy weather for many days in a row.
Lithium Battery
Lithium batteries have higher energy density, lighter weight, longer lifespan and better deep cycle performance than lead-acid batteries. However, the cost is higher.
Scenario: Suitable for applications with high requirements for energy density and lifetime, especially when there are restrictions on size and weight.
TOP 3 smart solar street lights
These are our smart solar lights and they have a built-in Bluetooth mesh network chip. Through IoT technology, it not only solves the problem that solar lights can’t be installed in layers of staggered installation, but also solves the problem that all lamps are turned on at night and off at dawn.
