Meta
Each panel is labeled with a Watt output. This is the STC (standard test conditions) number which is derived by flashing the panel in a controlled environment.
Most panels also have a PTC number which is lower (physical test conditions) which is gathered from the panel outside and operating.
Solar irradiance heat orientation weather also affect the production of a panel.
your mileage can vary

60 to 200 watts per square meter. depending on the panel.
References :
the bigger the solar panel the more energy. The smaller the solar panel, less energy.

did a sceince pro on it last yr.
what do you need the panels for? are they for water heating or to produce electricity? Generally, Solar panels vary significantly, they all have different specifications, they are made of different materials, some cheap and are not as efficient, and some are ok, just like everything else. There are other factors that affect solar panel energy output such as your location( if you are in Arizona, you get more solar radiation than someone in the midwest), the time of the year, the angle at which it is facing the sun- ray and many others. Although, panel specifications tell you the maximum output you can get out of the panel at given conditions (usually it is based on 1000 w/m^2, watts of solar radiation per unit area) 90 % of the time you do not get that. It only gives an idea of what you have but no real numbers. Besides, every part you add into your solar system reduces its efficiency.
Hope that helps

What kind of solar panel? I have a small one for maintaining a car battery, 5 watts. I’m thinking of putting some on my roof, spec’d at 225 watts (the 225 watts are bigger, but that wasn’t part of the question really.) I’ve seen them upward of 300 watts, and I’ve seen them range between 125-300 watts for roughly the same size. This is all assuming you’re speaking of electric, if you’re talking about thermals for water-heating or heating-heating, then you have to figure it out in BTUhours, and I’m not sure what the range, or calculation is from there, it may vary greatly too though, depending on things like insulative properties, etc.

It totally depends on a variety of factors. Location. Size. Sun Strength and quality of Solar Panels.
