Users or consumers often find there are lots of key factors in selecting outdoor solar lights，hence, we figure out top 3 factors here.
Top 3 Factors to Choose Outdoor Solar Lights
We all understand that we shall make a good quality product for our users across the world. No matter they are coming from Malaysia, Saudi, UAE, Sweden, Brazil, Australia, South Africa, Namibia, Uganda, or elsewhere, they will all be treated with a high standard quality product. Mostly, the solar-powered street lights are all in one type in the market. All in one is actually three in one type. Three means three major parts for solar street lights, i.e. solar panel, LED light, and battery. Therefore, I am recommending use to take a look at these top 3 factors before buying solar-powered street lights. Let’s begin.
1 – EFFICIENT SOLAR PANEL FOR OUTDOOR SOLAR LIGHTS

It took around two decades for photovoltaics (PV) or solar PV to become a mainstream electricity source from small scale applications. Price in the past could only be accepted by users like military and aerospace who don’t really care about the cost too much. Now, the price has dropped to a level that is affordable to civil users.
Solar panel energy has been developed for many years. Technically speaking, the product is mature enough. Usually, the high-efficiency solar cell will come with an MPPT controller for stable performance. The controller also takes care of light absorption in summer and winter.
As regards to the efficiency, monocrystalline solar panels are higher efficiencies and sleeker aesthetics than polycrystalline solar panels. Doubtlessly, polycrystalline panels are sold at a lower price.
Both monocrystalline and polycrystalline solar panels serve the same function in the solar PV system: they capture energy from the sun and turn it into electricity. The technology is so powerful that it can even work and provide lighting under weak light conditions. This is especially helpful in wintertime for high latitude areas like Sweden and Canada. Our customer in Sweden is continuously buying solar-powered street lights from us which is a great honor to us. It is sure that we have installed a special component unit for Sweden market which need complementary power in winter.
As mentioned, the solar panel industry has been developed for so many years. The solar panel itself is guaranteed with at least 20 years lifespan in most cases.
2 – OPTIMIZED LED LIGHTING SYSTEM
The top 3 factors for outdoor solar lights go number 2. LED chips are various and different chip vendors provide respective lighting solutions. Bridgelux, Cree, Lumileds, Nichia, OSRAM and Philips are common choices of solar lights factories who cherish their product quality and reputation.
For example, when we choose Bridgelux, we will take into consideration of LED power and lumen efficacy into consideration after comparison between brand and brand. Bridgelux has great performance regarding ESD protection. ESD protection devices (anti-static components) protect a circuit from Electrostatic discharge (ESD). The value of ESD for Bridgelux can be as high as 3000V. The product of the brand has high stability because it has a double electric shock structure and has 6 protective films on the surface. The factory is easier to operate in the downstream production process while the product yield is better controlled. At the same time, the light decay is less.
As a whole, other brands are also being picked for use when we produce a specific item since we need to consider the system output performance.
3 ENHANCED BATTERY UNIT EMPOWERS SYSTEM PERFORMANCE
The battery unit is outsourced from battery vendor. If an outdoor solar light manufacturer wants to use a low-cost component, then a lead-acid battery is possibly being used. The lead-acid battery has one of the lowest power-to-weight & power-to-volume battery designs in existence, making it big and heavy for the total amount of power it can put out.
In past years, quite many off-grid energy systems are equipped with lead-acid batteries. Now, most of them are defunct or replaced. People are turning to the solution of LiFePO4 lithium-ion battery.
LiFePo4 battery pack with 2000 times long life circles which is 3 times longer than Lead-Acid battery. When you browsing on the internet shopping site for outdoor solar lights, some vendors will indicate the warranty time of the product. Some warranties are so short that you will question yourself for what circumstance a customer will buy and question sellers for what kind of product they are selling at such a low price.
Moreover, please be aware of some suppliers who are using second-hand batteries taking down from electric vehicles.
Above the top 3 key factors are of fundamental importance as they are the main parts of outdoor solar lights.
We are carefully selecting our battery vendor and use the lithium battery product that can support a longer lifespan which is beneficial to both customers and us.
