Step 1
Solar panels are measured in power - Watts, volts, and amps.
When determining the overall wattage of a solar panel we use this simple equation:
Watts equals Volts multiplied by Amps.
You can use this table to find volts, amperage, and wattage if you know any two of the three variables.
Solar cells create about.5 volts of DC electricity regardless of physical size. The only thing that changes with the size of a solar cell is current. (AMPS).
Commercially available solar cell 3 inches by 6 inches output is more than likely rated at .5 volts with 3 amps of electricity.
Split a solar cell into two equal halves, each solar cell would be rate at .5 volts and 1.5 amps each. Volts stay the same, but amps changes with solar cell size.
CALULATIONS FOR SIZE
Determine how many solar cells to make a 60 watt solar panel.
We know that our 3 x 6 solar cells are .5 volts and have 3.3 amps. So we take 60 watts divided by 3.3 to get our overall solar panel voltage.
60watts divided by 3.3 amps equals 18 volts.
Solar panel voltage is 18 volts so we can find out just how many solar cells we need?
Solar Panel Voltage divided by single solar cell voltage equals the Number of cells needed per panel
so now we take 18 volts divided by .5 volts it equals 32 solar cells.
This means that we will need to wire these solar cells together in series to achieve the 18 volts.
SOLAR ARRAY
Commercial solar panel array systems consist of individual solar panels being connected in series to produce higher wattage.
For example, a 180 watt, 3.6 amp solar panel array system may consist of three 60 watt, 3.6 amp solar panels connected together in a series - 180 watts.
You achieve higher voltage by connecting solar panels in series.
