The amount of power you get depends on a number of factors, including the efficiency of the solar panels.
Ideally, the energy of sunlight would be about 1366 watts per square meter, but losses do to such things as the atmosphere reduce this to a practical limit of about 1000 watts. If a solar panel of one meter is 10% efficient, then this means you would get about 100 watts. New technologies are achieving efficiencies approaching 50%, which would produce 500 watts; but some older panels were only 6% efficient.
Since you ask about watts, I am assuming you mean photovoltaic panels. Solar thermal collectors are more efficient, but do not produce electricity.
Solar panels can make enough watts to power your whole house if you have enough of them. Some solar panels will generate 50 watts, 80 watts or 120 watts.
Modern panels are 9% efficient There are 375 watts per square meter available. If you look at the rating on the panel, assume roughly 70% of the rating. You can not ever possible hit the rated output of any panel.
Total power output of the sun: 3.86 x 1023 kilowatts (386,000,000,000,000,000,000,000 kilowatts) Total solar power received on Earth: 1.74 x 1014 kilowatts (174,000,000,000,000 kilowatts) Solar power falling on 1 square meter of ground: 750 watts (0.75 kilowatt) Output of a 1 square meter solar panel: 120 watts (0.12 kilowatt)
Fukushima Generates around 13,000 Mega watts of electricity. You need 434 Solar Panels for 1 Mega Watts. Calculation 434 Multiplied by 13,000 Equals to 5,642,000 Solar Panels. Cost of 1 solar panel 3,500 $ So 3,500 Multiplied by 5,642,000 = 14,747,000,000 USD. A single Nuclear Powerplant costs 400 Million USD.
The best technology so far (2015) gives about 150 Watts per square metre.

About 1,000 watts per square meter of solar panel
The value watts/square foot (W/ft2) is a value of "energy density" for solar panels, indicating their peak power output. Mass-produced solar panels are currently producing up to 13 W/ft2 or about 140 W/m2. The SI unit watts/square meter (W/m2) is also the unit of solar irradiance, which measures the energy received by a surface exposed to sunlight. The average solar radiation received at Earth's surface is about 342 W/m2 and the maximum is about 1000 W/m2.
Modern panels are 9% efficient There are 375 watts per square meter available. If you look at the rating on the panel, assume roughly 70% of the rating. You can not ever possible hit the rated output of any panel.
Solar panels are rated in watts output. To find the amperage use this equation, Amps = Watts/Volts. The wattage will be on the nameplate of the solar panel.
It ranges from 1.361 kilowatts per square meter at solar minimum to approx 1.362 kW/m^2 at solar maximum

None. Watts is unit of power. Square meter is unit of area.
To calculate the power used it is necessary to add up the power requirement: typical power values would be solar fans 0, fridge 20 watts average, lighting 200 watts, cooker up to 3000 watts, heater up to 3000 watts, mobile charger 3 watts, TV 150 watts. Solar panels of around 1.2 metres by 1 metre produce about 220 watts in maximum conditions, or about 15 watts out of direct sunlight. So without the heater or cooker a couple of panels should do it on a sunny day, otherwise add 15 panels for the cooker OR the heater.

It's just like any other budget. You start by figuring out how many watts you use.
