There is no "electricity" produced when the panel is disconnected from a load. For it to be actual electricity there must be both voltage and current. With the load disconnected you have voltage (i.e. potential) but no current.

If there is no-load connected to a solar panels terminals, then the panel will generate no current as there is no electrical circuit for it to flow around. But if the terminals are shorted together, the current demand is very high so the photovoltaic panel generates its maximum output current, commonly called its short-circuit current, I SC from the available light.

Under optimum conditions and no load, your panels will have a voltage of 22.1 volts. With no load, you say the voltage is 19 volts - that means your solar panels are not getting full sunlight to produce 100 watts. The inverter will waste a good bit of power in converting the DC from the solar panels to AC.

In other words, if the voltage of your battery (the load) is higher than that of your solar panel, then your solar charge controller will not allow the current to flow from your solar panel back to your battery to charge it because the circuit is open. Thus, your display will indicate that your solar panel has voltage but no amps. There are

A solar panel that is not connected to a load produces a voltage but no current. This is because there is nothing to form a circuit through which the current can flow. This will result in the solar panel getting warmer.

Note: If your solar panel controller also has a regulated Voltage output (Voltage is never more than 12-13V DC) then the current supplied to the battery may depend on the voltage that the battery has.e.g if the solar output is 12.3V and the battery is 12V then the battery is only being charged by 0.3V and the charging current will be small.

Low amps or current is one of the most common problems you will face if you are running a solar system. You are literally getting low power output. Always make sure to place your solar panel where there will be no possible shade. If there are things that are shading it consider removing them or moving you panel elsewhere.

Measuring the full power output of a solar module requires a load. However, as a first step, we can use a simple multimeter to measure with no load to get the open current voltage, (V OC) and short circuit current (I SC). For large outdoor modules, any multimeter with a current scale that goes to 10 A (amps) and 50 V (Volts) will work.

Learn MoreA solar panel with no load isn't connected to any devices. When not connected to a device, a solar panel will still absorb sunlight but won't have anywhere for the energy to go. It has voltage, but no current is flowing. Because the voltage has nowhere to go, it will become heat in the solar cells and radiate from the panel until it dissipates.
The article addresses a common issue where a solar panel shows voltage but no current (amps), leading to a malfunction in the system. It discusses the diagnostic process, including checking standard ratings and setting up the panels for optimal sunlight.
There is a good chance that you may see there is voltage but no amp (which means current). Why? Solar panels having voltage and no amps are mostly caused by an open circuit. In simple terms, it means your circuit is incomplete or flawed. Causes include using wrong voltage, wrong Connection, problems with panels or solar charge controller.
Another way Open Circuit happens is using more Load Voltage than panel voltage. As said earlier current always flows from high voltage to low voltage. When the voltage of your load (Load is something you connect to Solar Panel. Take Battery for Example) exceeds your panel's volt current would not flow from the panel. It'll be reversed.
A solar PV system that isn't collected to a load will remain in an open circuit condition. That's another saying that it will absorb the sun but have nowhere to send the power. As discussed above, this is fine for short periods but can cause damage if done continuously. Can Solar Panels Charge With Indirect Sunlight?
Start by setting the clamp meter to measure DC amps. To do that, turn the clamp meter's dial to the correct amps setting. Then measure the Solar Panel's current. Finally, compare the current reading to the panel's max power current. That's all about the matter when your solar panel has voltage but shows zero amps.
