Why do devices charge slower with solar power?

[Fidelia]

I have observed that when I want to charge my phone and laptop with solar system, the devices don't seem to charge as fast as when they are being charged with normal electricity.

What makes charging devices with solar power much slower?

The main reason why charging devices with solar power is usually slower than using conventional electricity is the amount of energy the solar system can generate compared to the electrical grid. Solar panels, while effective, depend on the intensity of sunlight, which varies throughout the day and depending on the weather. Furthermore, most portable or home solar systems have a limited capacity compared to the power offered by the electrical grid, resulting in slower charging speeds. Other factors also play a role, such as the quality of the panel, the type of battery, and the efficiency of the inverter or charger. In short, solar power is a sustainable and environmentally friendly option, but it still cannot match the speed and amount of energy provided by conventional electricity. Therefore, solar charging is generally slower, especially in less-than-ideal lighting conditions.

There is nothing much all I know is that Solar is not really good for charging there is no way which you can compare charging your device with electricity with that of solar.
Solar weal battery cell I have observed it myself but I don't know why it's charge things slowly

It's probably due to the fact that the panel is producing less output energy hence the charging would be slower.
