My solar panels specs are 12 volts and 60 watts. What does 60 watts mean?

How do you get a number like 60 watts? Power changes all the time depending on light intensity. Is there a way to experimentally confirm this number? I’ve tested it outside and I get open voltage of 22V and closed circuit of 10A.

I am sure Violet has some very good web sites
Your spec sheet data should also mention max current.
As you measured 22V and 10A does not mean you can use-it at 6V10Amps. It will die young if you do.
But most likely 12V at 5Amps is perfect.
It is your regulator circuit that has to limit the consumption.
This is part of the charger controller’s job.

Hope this properly answers your question
