For the third example, we have 4 100W-12V solar panels. And same as the 2nd example, these panels are wired in 2S2P. However, the solar panels in this system need to charge 2 series wired 100Ah-12V batteries. So for this example: We have 2 parallel strings. 2 solar panels in each string. The power rating of our solar panels is 100W.
To calculate the energy it can supply the battery with, divide the Watts by the Voltage of the Solar Panel. 120 Watts / 18v = 6.6 Amps Please note that Solar Panels are not 12v, I repeat Solar Panels are not 12v. Any one who works out the Amps of a solar panels using 12v as the voltage calculation does not understand solar or has been misinformed.
Both are important. Amps determine how many watts a solar panel produces. That said, when it comes to sizing solar panels, watts is a more useful measure. That''s because it tells you how much power the solar panel produces and how quickly it can charge a battery. How many amps does a 200W 12V solar panel produce?
A solar system with this power rating would consist of 4 – 100W solar panels, 2 – 200W solar panels, or even a single residential solar panel rated at 345 Watts or more. Here are a few examples of different refrigerators, their daily energy consumption, their location, and how much solar power would be needed for each of them to run:
