Let's say how much energy could potentially be yielded per day from a 100cm squared solar panel in mAh?

The maximum amount of solar energy that could be yielded per day from a 100cm squared solar panel in mAh depends on several factors, such as the location, the weather, the orientation, the efficiency and the voltage of the panel.

First, let us assume that the panel is located in a place with an average solar radiation of 5 kWh/m² per day, which is typical for many regions in the world. Second, let us assume that the panel is tilted at an optimal angle to maximize the solar irradiance on its surface. Third, let us assume that the panel has an efficiency of 20%, which means that it can convert 20% of the solar energy that hits it into electrical energy. Fourth, let us assume that the panel has a voltage of 5V, which is common for many small devices.

Using these assumptions, we can calculate the maximum amount of solar energy that could be yielded per day from a 100cm squared solar panel in Wh (watt-hours) as follows:

E (Wh) = A (m²) * H (kWh/m²) * r (%)

Where,

E is the energy in watt-hours.

A is the area of the panel in square meters.

H is the solar radiation on tilted panels in kilowatt-hours per square meter per day.

r is the efficiency of the panel in percentage.

Plugging in the values, we get:

E (Wh) = 0.01 m² * 5 kWh/m² * 0.2

E (Wh) = 0.01 Wh

This means that the panel can produce 0.01 Wh of energy per day at maximum.

To convert Wh to mAh (milliamp-hours), we need to use another formula:

Q (mAh) = E (Wh) * 1000 / V

Where,

Q is the charge in milliamp-hours.

E is the energy in watt-hours.

V is the voltage in volts.

Plugging in the values, we get:

Q (mAh) = 0.01 Wh * 1000 / 5V

Q (mAh) = 2 mAh

This means that the panel can produce 2 mAh of charge per day at maximum.

Therefore, the maximum amount of solar energy that could be yielded per day from a 100cm squared solar panel in mAh is 2 mAh.

Just so we're clear this answer was generated by AI but if we assume it is without error you can see how a phone is not a good candidate at all however very low energy use devices like remotes are able to maintained by trickle charging day by day. I think my Apple TV remote took a year to run out of charge and I use that more than the Samsung remote and it's much smaller and thinner too. Remotes can get away with it as they use almost nothing on a daily basis, phones absolutely not.
