Brief question about solar cells?

So I’ve been browsing around for a while, trying to get a basic hang of modern solar cell technology. So far, I think I’ve gotten a decent grip of how the things work, but there’s one thing that confuses me.

At first, I thought the Power Efficiency Rate was the primary factor to a good solar panel.
But then, when reading up on the costs of solar panels, I read that you pay a cost per watt of solar modules.

I don’t really want to get too deep into how the cells produces electricity, but I thought that if the sun shine with 1000 W/m^2 over a m^2 solar panel with an efficiency rate of 10%, it generates 100W. However, seeing as different panels seem to have different "Watt outages", would the Watt of the solar module act like a limiter for how much energy you can generate?

Like, if the sun shines with 1500W/m^2 and I have a 125W, 1m^2 solar panel with 10% efficiency, I’d only get 125W?

I’m sorry if my question is hard to understand, I really wanted to ask this before making dinner.
Any answer is appreciated! 🙂
