It depends on many factors, such as weather conditions (how much sun there is in the specific time, which can also be affected by which hemisphere you're in). Speaking generally, solar panels have low energy density (many are needed for a significant amount of energy.) But after the initial buy, it's free and renewable!
10 square feet creates 100-200 watts.
It depends on the size of the solar panel and how well built the product is and the energy holding capacity of the battery.
more than 2%
I assume they come in different sizes, but a typical commercial solar panel generates about 50 watts.
About 1,000 watts per square meter of solar panel
Depends on the type of solar panel. You would need to look at the manufacturer's data to know the exact amounts.
You can compare the chloroplast in a plant cell to a solar panel. Much like a solar panel, the chloroplast receives energy from the sun and converts it into sugar and the green coloring to a plant. A solar panel uses the sun's energy to convert it into energy to light a house etc.
I do not think so. There is not much sun at the noth pole is there? And the, solar panel would not get much energy would it?
Depends on the physical size of the solar panel, and more-than-likely, the quality of material it's made of.
It really depends on where you live, and how much sun your place gets. But on average, an average solar panel might be able to produce 17.5kwh per day.
4 Watt-hours
not much.
The same amount it would need from your electrical supplier.
