In the same condition of solar panels and batteries, Double MPPT technology brings 1.3A charging current, normal MPPT technology only brings 0.94A charging current.
Double MPPT technology has a higher efficiency of 40%.
All Viet Sky Solar’s products are using Monocrystalline silicon crystal panels, also known as Mono solar panels.
Currently there are two types of silicon crystals that used to make solar panels: Monocrystalline (Mono) and Polycrystalline (Poly). A Mono solar panel is more efficient than a Poly solar panel, Mono solar panel has an efficiency of 17-21%, while a Poly solar panel is only 13-16%.
Based on the external characteristics, we can distinguish Mono and Poly panels through the following two characteristics:
Mono solar panels are black or dark blue color
Poly solar panels are lighter blue color
Mono solar panels can have oblique or square angles on the edges
Poly panels only have square angles, do not have oblique angles
Problems you may have with solar panels:
Before the product sent to our customers, we will check the solar panel 3 times to bring you the best products. The first time is at the solar panel factory, the second time is at the light factory, and the third time is before sending the light to the customer.
100% new battery, using 18650 battery, charge and discharge up to 800 times, the usage time is up to 5 years.
Products using recycled batteries certainly do not have a charge and discharge cycle up to 800 times, this will affecting battery life and light performance.
Our products are using 100% new batteries, guaranteeing not to use recycled batteries for Viet Sky Solar‘s light products.
Difference between new and recycled batteries:
Most solar lights use one of these following kind of batteries 32650/22650/18650.
Just use our eyes, we can identify the characteristics of recycled batteries:
You need to pay attention to battery products with 2 metal heads, most of these batteries have a high likelihood of being recycled batteries, those with 2 metal heads are usually manufactured for use in electric cars, but it is not qualified enough, so they used for solar lights.
In some cases, people will use the machine to cut the metal heads, due to the impact of vibration and temperature during the cutting process, so the surface of these batteries is often leaked, watery and lead to rust, not clean and shiny like new batteries.
