The rated voltage of the solar cell is 12V, and the capacity is 80AH. How long can the 4 million full-color camera 12V2A shoot?

First of all, we need to calculate the total power of solar cells, which can be calculated by multiplying the rated voltage (12V) by the capacity (80AH), that is, 12V * 80AH = 960Wh.

Then we need to calculate the total power of the camera, which can be calculated by multiplying the voltage (12V) by the current (2A), that is, 12V * 2A = 24W.

Next, we can calculate the time that the solar cell can supply power to the camera, which can be calculated by dividing the total power by the total power, that is, 960Wh/24W = 40 hours.

Therefore, solar cells can be used for 40-hour cameras. However, it should be noted that this calculation result is obtained under ideal conditions, and the actual use time may be affected by solar energy intensity, panel efficiency, panel aging and other factors.
