Yes. The working voltage of the 30 watt solar panel is 18V, the working current is 1.5-3A, while the voltage of the router is 9-12V and the power does not exceed 20W. 30 watt solar panel can enable operation. Router status, so the 30 watt solar panel can bring a router.
Solar batteries are not the same as batteries
A battery will consume electricity through self-discharge after a while if you do not connect it to a load once it is is fully charged.
The power output of the solar cell is determined by the load
That is, the solar cell must produce power even if you add electricity to it. 'light energy
.
Moreover, you need to understand one thing,
That is, solar cell is not an energy storage device
p>It's just an energy conversion device
Only when you connect a suitable load
can you get maximum power or maximum efficiency
An open circuit of the solar cell
An open circuit of the solar cell
p>
is equivalent to your charge being infinite
Then the power of the solar cell itself cannot not be released
But it does not affect the performance
Because the solar cell at this time is equivalent to an open loop circuit
It does not there is no current.
The light energy you add does not stimulate the movement of electrons
The energy you are concerned about is a form of thermal energy that is consumed on the surface of the solar cell
Let me give you an example
You put a plant with green leaves under the sun
Since the green leaves they themselves must carry out photosynthesis
Thus, the green leaves will absorb energy andwill make the plant grow
If you put a dry leaf on it
Although you always add light energy
But this light energy It is not not absorbed
The same goes for solar energy in open circuit solar cells
Although you add light energy
but this energy light is not converted into electrical energy
So it will not affect the lifespan of the solar cell itself
If the solar cell is short circuited
This is equivalent to your load being infinitesimal
All the power in your solar cell The power adds to the load
The current flowing through it instantaneously is infinite
The actual current cannot be infinite
You can use a multimeter to measure the current in a short circuit< /p> p>
The current measured is the short circuit current
If the current is too high, the solar cell heats upra
If the light source is sufficient and the output power is too large, the internal crystal structure will be damaged
The short circuit current multiplied by the open circuit voltage is the theoretical maximum output power of the solar cell
In practical applications
The output efficiency of the solar cell should be adjusted to the optimum point

This is the technology commonly known as MPPT maximum power tracking< /p>
