The main reason why solar panel installers deem as necessary the usage of solar energy storage in off-grid PV systems is the stability for voltage and frequency.
Not really because the watt to surface ratio is about 150-180 watts per square meter. If you touch the solar panels you will feel the heat. But usually it is not going to be a problem. A solar panel will not turn solar energy into direct current until there is a circuit.
A solar panel will not turn solar energy into direct current until there is a circuit. If there is no circuit, the solar panel will just “sit there” as the photons will not be converted into electricity. The panels will get hotter true, but the modules are going to get hot anyway if you connect a load to it.
I use several ATSs (automatic transfer switchs) to connect my off-grid solar to the house. When the PV -> battery charges up enough to turn on the Inverter - the Inverter power flips the ATSs from grid to inverter. When the batteries run down and the inverter goes off, the ATSs automatically switch back to grid.
The situation is comparable to a battery. A fully charged battery – the Vmaxtanks 125ah AGM is a good example – can power several appliances and devices, but it must be connected to a load. Without any connection it is just potential energy. The same thing can be said for solar panels.

Abstract— The small scale electricity generators such as solar photovoltaic (PV) systems are generally connected to the grid at the primary or secondary distribution and are considered as distributed generation (DG). Often, these small scale renewable generators cannot be directly connected to the grid.
The energy production of a grid-connected PV system depends on various factors. Among these we distinguish the rated characteristics of the components of the PV system, the installation configuration, the geographical siting of the PV system, its surrounding objects, and defects that occur during its operation.
In order to improve the stability of large-scale PV and energy storage grid-connected power generation system, this paper proposes the evaluation method to assess the virtual inertia and damping demand of the VSG emulated by the energy storage, as well as a technique to suppress the forced oscillation by shifting the natural frequency.
