The earth receives an average of 164 watts per square meter from the sun. This is the average spread over the world including poles and tropics, night and day. The energy in units used commonly in commerce (kilowatt-hours) would be about 45 millionths of a kilowatt hour per second per square meter.
More important is the calculation of how much usable energy reaches the ground where the energy could be put into use. At 40 degrees latitude (the rough middle of the US) during the 8 peak hours of the daylight, each square meter will receive about 4.8 kilowatt hours.
Averaged over the whole world: 164 Watts per square meter over a 24 hour day.
At 40 degrees latitude on a sunny summer day: 600 Watts per square meter.
At 40 degrees latitude on a sunny winter day: 300 Watts per square meter.

The Sun's energy is given out mainly as "electromagnetic radiation". Light is a form of electromagnetic radiation. Heat is the main form the Sun's energy has when it reaches Earth, particularly the Earth's surface.

That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy. The formula for gravitational potential energy is PE = mgh, that is, mass x gravity x height. If mass is in kg. and gravity in meters per second square (use the value 9.82 for Earth's gravity), and height in meters, then the energy will be in Joule.That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy.

The light travel directly through the vacuum and reaches earth
It reaches earth as an electromagnetic wave.
The energy that reaches the Earth from the sun is known as sunlight.
