Many Buyers are confused about the solar product and price after they check with different suppliers.We would like to tell you something the other suppliers always want to hidden.
Product can be great different when the appearance is the same. Quality is different because factory use different battery, solar panel ,LED chip and other material. The materials are hard to identify by eyes. It's also hard to see the difference in the early period after installation. But you will see the difference about half year after installation.
Take the battery as an example. Same size 32650 Life PO4 battery capacity can be as low as 2500 mAh/cell (the second hand battery),it can be 5000 mAh/cell also. Cost of one cell 5000 mAh battery (new battery) is much higher than the cost of two cell 2500 mAh battery (second hand).
There are two different situations now:
1. Factory use 2 pcs 2500 mAh to make 5000 mah battery pack and they tell buyers the battery is 5000 mah. It seems they tell the true, but the 5,000 mAh(two pcs second hand battery) will die very fast. The battery backup time decrease a lot after about half year installation.
2. Worse situation is the factory use one pcs 2500 mAh battery but says it's 5000 battery. People cannot identify by eyes but the performance very bad when use the solar light.
Battery seems the same when look by eyes, but we can see the different when we test.

About our battery test. you can see above video for reference. We test very strictly and use good quality battery.
Beside the battery, solar panel also can be great different. When you look by eyes, it's same. But the charging efficiency is different when test and use. Efficiency of good solar panel can be 17%, but it maybe 13% or even lower when factory use bad quality solar panel.
About the lamp case, some factory use very thin aluminum alloy and the product feel very bad when you touch. Some factory even use Plastic Lamp case. This also lead to different cost and price.
Above are the main reasons why solar light price different from each factory.
