What Can I Power with a 100W Solar Panel? | altE Solar Blog

OK, back to the question at hand, what can I power with a 100W solar panel? I need to figure out my worst case scenario, what is the worst performing month that I’ll be using the panel? Since, for this example, I’m going to be using it in Maine, during ski season, I need to figure on December. So how can I squeeze out as much power as I possibly can in December? By tilting the solar panel steeper so it points right at the low winter sun. So I’m going to mount my 100W solar panel at 60 degrees and figure on 3.2 sun hours. I’ll now take 100W x 3.2 sun hours and get 320 watt hours a day in December. Now, as you know, nothing in real life is perfect, so I have to figure in losses that I’ll likely incur, such as voltage drop across the wire, dirt (or snow) accumulating on the solar panel, losses through the charge controller, etc. So I’m going to multiply the 320 watt hours tim...
