Solar PV Panels
Solar Panel Output
Solar panel output is measured in watts.
Try the
Solar Calculator.  

Calculating Wattage
Wattage is calculated by multiplying the rated voltage by the rated amperage. The formula for wattage is VOLTS times AMPS = WATTS.   For example, a 12 volt 60 watt solar panel
measuring 20 X 44 inches has a rated voltage of 17.1 and a rated 3.5 amperage.  V x A = W 17.1 volts times 3.5 amps equals 60 watts.  

Watt Hours
If an average of 6 hours of peak sun per day is available in an area, then this solar panel can produce an average 360 watt hours of power per day; 60w times 6 hrs = 360 watt-hours.

Peak Sun Hours
The intensity of sunlight varies throughout the day, therefore the term "peak sun hours" is used to smooth out the variations. Early morning and late-in-the-day sunlight produces less
power than the mid-day sun.  Cloudy days produce less power than bright sunny days.  Geographical areas are rated in average peak sun hours per day based on yearly sun data.

Series or Parallel
Solar panels can be wired in series or in parallel to increase voltage or amperage.

Series wiring connects the positive terminal of one panel to the negative terminal of another. The outer positive and negative terminals will produce voltage the sum of the two panels,
but the amperage remains the same as one panel. So two 12 volt/3.5 amp panels wired in series produce 24 volts at 3.5 amps. Four of these wired in series produce 48 volts at 3.5

Parallel wiring refers to connecting positive terminals to positive terminals and negative to negative. The result is that voltage stays the same, but amperage becomes the sum of the
number of panels. So two 12 volt/3.5 amp panels wired in parallel would produce 12 volts at 7 amps. Four panels would produce 12 volts at 14 amps.  

Series / Parallel wiring refers to doing both of the above - increasing volts and amps to achieve the desired voltage as in 24 or 48 volt systems.

Please Note - Solar PV Panel
prices continues to fluctuate.
Due to increased worldwide
production, economies of
scale and government
subsidies, panels have gone
from approximately $5.00 per
watt a few years ago and
industry experts like SEI
expect prices to be as low as
$1.00 per watt by 2012.  We
can help configure a system
and identify the highest
quality products at the most
current and affordable price.
