Step 1:
Look at the back of the solar panels or consult the manual that came with them. Note the maximum power voltage (Vmp) in volts (V) and the maximum power current (Imp) in amps (A). Multiply the two numbers together to calculate the maximum power of the solar panel in watts (W). For instance, if Vmp is 17.2 V and Imp is 1.17 A, multiply 17.2 by 1.17. The product of these two numbers -- the wattage -- is 20.12 watts (W). The rated power of this particular solar panel would be specified as 20 W.
Step 2:
Manufacturers measure the maximum power voltage and current at standard conditions of temperature and insolation. The electrical power that a solar panel connected in the home generates will, most of the time, be less than this maximum level. Consult the specification sheet for the solar panels. Look for diagrams called "I-V curves." These diagrams show how the power of a solar panel is lower when there is less sunshine and when the temperature of the cells is above 77 degrees Fahrenheit.
Step 3:
If your solar panels are producing electricity in the home, you can measure the electrical power directly. Use a digital multimeter to measure the direct-current (DC) voltage produced by the solar panels at the point where they are connected to the charge controller. Write down the voltage measured in volts.
Step 4:
Measure the DC current in the circuit using the digital multimeter. Follow carefully the instructions in the multimeter manual for this procedure. Write down the current measured in amps. Multiply the voltage by the current to calculate the electrical power in watts.

How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
How Much Electricity Does One Solar Cell Produces in one Minute?
One solar cell will produce 0.6 volts at up to 4 amps. This would be a total wattage of about 2 watts. There are a great number of variances that could make this number higher or lower, but is a good basic reference.
Is a solar cell an energy source?
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
What term is used for the energy transferred by a cell to the current?
Current I think
What is the energy change of a solar cell?
I've found it out. It's; Light-->solar cell-->voltmeter.
When a solar panel is mounted with solar cells it what will it produce?
d.c. wattage
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
How much power does a solar charger need?
Depending on what exactly you are asking, probably about portable solar charger. It depends on what wattage your mobile device needs. Most cell phones are 5 watts, so you will a solar charger in that wattage level. You can also get one that is lower, however the charge time will be longer. Also, be sure that you purchase a solar charger that has a built in battery pack that way you can rely on that when the sun is not out or during the night.
How do you calculate line current?
Devide the wattage by the voltage
How Much Electricity Does One Solar Cell Produces in one Minute?
One solar cell will produce 0.6 volts at up to 4 amps. This would be a total wattage of about 2 watts. There are a great number of variances that could make this number higher or lower, but is a good basic reference.
What is the Formula for calculating efficiency of a solar cell?
Efficiency = energy out as electricity / energy in as light At full sun, there is approximately 1000W/m^2 Since your solar cell is not a square meter, you have to scale the answer. Step 1 : Convert the Cell Area (mm sq.) to Meter Square Step 2 : Divide the known wattage by the area M square Example : If it is 156 mm x 156 mm Sq. Cell , then the Area would be : 0.24336 M. Sq Now, if the Wattage is 3.86 Wp , then the efficiency would be 3.86 divided by 0.24336, = 15.86%
How much electricity does a standard solar panel produce cost wise and wattage?
What is more effiecient? a solar thermal system or a solar photovolaic system?
How can you get the wattage of a 1x3 solar panel when it is 17 volts output?
u multiply your voltage times max current (amps) and this gives u max wattage.
How do you know how much solar energy a solar panel collects?
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).
Calculate how much power will typically be generated by each solar cell at AM1.5?
Best i got is =14.4 mW cm^(-2)
How many lights can be powered by solar panels?
That would depend on the size of the panel and the wattage of the light
What does the solar cell do in space?
The function of solar cell is to convert the energy from the sun into electricity. This is commonly referred to as a photovoltaic cell.
