A 20 watt solar panel produces 20 watts of power/hour when it is in direct sunlight. However, this varies depending on the conditions. It won't produce at 100% in cloudy conditions. Let's say the 20 watt panel gets about 5 hours of good sunlight everyday between 10am and 3pm. This will produce .1 kWh or 100 watt hours. This means you can run a 100 watt bulb for one hour or two 50 watt bulbs for one hour.

That depends on the panel.
500 volts!!
A common solar panel can produce around 200 watts of power and can vary based on the size and efficiency of the solar power you chose. There are also three things that can affect the amount of electricity that a solar panel produces: the amount of sunlight, the size of the panel and the efficiency of the solar cells.
depends on the size of the solar panel and the weather. the bigger the solar panel and sunny weather will generate more electricity
yes it does
7.4 acres
What is more effiecient? a solar thermal system or a solar photovolaic system?
That's impossible to answer. It depends on: - The size of the solar panel - The type and even brand of solar panel - Location - Orientation - Time of year - Weather
Savings from solar systems depend on the total area where the solar panels are installed. You can use solar savings calculator available at solarbuddy dot com to know how much you can save on electricity bill by installing solar panel systems on your home roof top.
Well, yes, but the light is so weak that you won't generate much electricity.
not much.
By measuring the output. Each solar panel has a wattage, for example, 200 watts. You can multiply that wattage by the number of hours in a day that the sun shines, for example, 6 hours, and the answer is in kWh (0.2 kW x 6 = 1.2 kWh).
