Product Description
The working principle of solar panels
The solar panel generates current when sunlight hit the cells which are welded in different series and parallel according to 12 or 24V system requirement.Current will charge battery through solar controller which preset with protection function of over charge and over discharge, working duration time for LED lamp. When darkness comes voltage of solar panel will drop down whichtriggers the solar
controller open circuit to discharge, and that makes LED lamp turn on.

Mono solar panel:
The photoelectric conversion rate of monocrystalline silicon solar panels is 15%-24%, which is the highest photoelectric conversion efficiency among all types of solar cells. However, the production cost is so large that it cannot be widely used in large quantities. Because monocrystalline silicon is generally encapsulated with tempered alass and waterproof resin, it is durable and has a service. life of 15-25 years.
Poly solar panel:
The technology of polycrystalline silicon solar panels is similar to that of monocrvstalline silicon solar panels, but the photoelectric conversion efficiency of polycrvstalline silicon solar panels has to be reduced a lot, and the photoelectric conversion efficiencv is about 12%-14 8% In terms of production cost, it is cheaper than monocrystalline silicon solar panel, the material is easy to manufacture, it saves electricity consumption, and the total production cost is lower.

FAQ
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Q1: Can I have a sample order for solar products?
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
Q2: What about the lead time?
A:Sample needs 3-5 days, mass production needs 1-2 weeks for order quantity more than one container
Q3: How to choose the system Voltage 12V /24V ?
A: We could design the system for you .Usually 12V system for 15W-40W LED lamp , 24V system for 50-150W LED lamp
Q4: How do you ship the goods and how long does it take to arrive?
A: Sample shipped by DHL, UPS, FedEx ,TNT etc. It usually takes 3-5 days to arrive. Airline and sea shipping also optional .
Q5: What is your Warranty Policy?
A: We offer 3 to 5 years warranty for the entire system and replace with new ones for free in case of quality problems.
