How much energy can a solar panel collect in one hour?

AI Thread Summary
The average intensity of sunlight at the Earth's atmosphere is approximately 1400 W/m². A 20 m × 30 m solar panel can theoretically collect energy based on this intensity. To calculate the maximum energy collected in one hour, the relationship between power, energy, and time must be understood, specifically using the formula P = E/S. The intensity of sunlight can be used to determine the total energy by multiplying the area of the solar panel by the intensity and the duration in seconds. Understanding the units of watts as energy per time is crucial for solving the problem.

Homework Statement



The average intensity of sunlight at the top of the Earth's atmosphere is about 1400 W/m^2. What is the maximum energy that a 20 m × 30 m solar panel could collect in one hour in this sunlight?

Physics news on Phys.org
i was thinking about P= E/S. The intensity is power/area. So 1400/600= 2.33. But how do we relate this intensity to E/S (s being 3600 seconds).
 
Think what the units of a watt are and how power and energy are related.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
