The best technology so far (2015) gives about 150 Watts per square metre.
The conversion factor from lux to watts per square meter (W/m2) is 1 lux 1 watt per square meter.
That's not a special kind of light - you can do that with any light. The power per area (e.g., watts per square meter is a measure of INTENSITY.
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.
The amount of time it takes to generate 375 watts of energy with a 1 square meter solar panel depends on the efficiency of the panel and the amount of sunlight it receives. On average, a good quality solar panel can produce about 100-200 watts per square meter, so generating 375 watts may take a few hours under optimal conditions.
There are two types of solar panel, the solar thermal collector, and the photovoltaic cell. The first simply collects thermal energy from the sun and transfers it to a fluid, usually water. this is quite useful for domestic hot water, warming swimming pools, and can be used industrially to prewarm feedwater. The photovoltaic cell responds to visible sunlight and produces a small dc current from semiconductor material such as silicon, doped with impurities. The theory says that photons of light energy cause electrons to be displaced resulting in a current flow. In bright sunlight it takes 1 square meter of cells to produce 120 watts of power, but this is only available at peak sun intensity during a 24 hr cycle. These figures are for the first generation of cells, much work is ongoing to improve efficiency and make production cheaper.
None. Watts is unit of power. Square meter is unit of area.

Watts is a unit of power (energy per time). Square meter is a unit of area (length squared). These units are not convertible between each other.

About 1,000 watts per square meter of solar panel
The earth receives an average of 164 watts per square meter from the sun. This is the average spread over the world including poles and tropics, night and day. The energy in units used commonly in commerce (kilowatt-hours) would be about 45 millionths of a kilowatt hour per second per square meter. More important is the calculation of how much usable energy reaches the ground where the energy could be put into use. At 40 degrees latitude (the rough middle of the US) during the 8 peak hours of the daylight, each square meter will receive about 4.8 kilowatt hours.
Energy: joulesPerhaps you mean power: that would be joules/second = watts Intensity is measured in watts per square meter.
The conversion of Anson-units is that in Chemistry you have to multiply by the conversion units, to get the Anson-units.
To convert a measurement from milliwatts per square meter (mW/m2) to watts per square meter (W/m2), you need to divide the value in milliwatts by 1000. This is because there are 1000 milliwatts in 1 watt.
