Electronic tags. Solar panels used, etc. are used to load electronic labels. Solar panels rely on solar energy for charging. ETC solar equipment can be charged as long as there is a certain amount of light. This solar ETC has two built-in batteries, including a long-lasting, non-rechargeable battery for the system. memory.
Without knowing your system voltage
I can only estimate based on my experience, assuming your battery is 12V,
use 18V solar cell board, size 1.1*0.8M can output about 110W power
If 10 of them are used in parallel, the total power will be 1100 W, the voltage will be 18 V and the current will be around 60 A.
I hope I can help you.
I am an expert. Is this answer not professional enough?
