Anyone have a generic equation to calculate the energy that is harnessed?
I think it would be something like Area x Efficiency x Time ??

I DON”T KNOW!!!
The energy received at the earths surface from the sun is approximately 1Kw per sq m
So with a panel in full sun, with the panel facing the sun, Area(m) x efficiency will give you the approximate output in Kw
Multiplying this by the number of hours of sunshine to give the power produced per day will only work if if you have a tracking system to keep the panels pointing in the right direction.
A guide to power that may be produced at different latitudes can be found at the link below.
well, I had the same question a while back and found great information like this :
Individual solar modules that are measured in watts have a particular voltage (around 40 volts) and a particular amperage (around 5 amps). A solar module with 40 volts and 5 amps is called a 200-watt module, which means that it has the potential to produce 200 watts of electricity when in direct sunlight.
Also, you will need to determine the load of your appliances, there is a great calculator on the website shown below
