Hello everyone and happy holidays!

I'm interested in photovoltaic panels, it's the future and all!

But with the subsidiaries and the general enshittification of search engines, all search results about photovoltaics leads to sites with wildly misleading information, IMO.

I don't care about a 3kWc system with installation. What even is a kWc (I know what it is) and why is nobody explaining how much power the panels would typically yield instead? Per month? During the day?

I guess it is less selling if your installation is generating near nothing in December when you need it the most?

Okay sorry, rant off. My question is, where can I find reliable information about how much panels generate every month, during the day?

I know places have more or less sun, but that's quite easy to figure out if you have the numbers for any place.

Edit: I don't need a web calculator for how many panels I need. I'd like to know roughly how many watt a typical panel produces a specific day (or better hour) in the year.

Edit2: I am not looking for how to install or calculate a typical solar panel setup. I'm looking for the typical real world output of solar panels around the day and year.

Edit3: got my information, thanks oo1@lemmings.world ! You all can now continue explaining how many panels a home needs or what a kwh is, Merry Christmas to you all!

Solar panels don't generate constant power! That's why it's wrong because you'll get wrong numbers. You can't assume you'll get peak output continously.

You *** must *** calculate incoming and absorbed light. The Watt output will vary continously as the sun moves and weather changes. If you have average kWh / day stats and a battery solution that can store a day of battery, THEN you can calculate average Watts if weather doesn't change too much.

Just FYI I'mnot looking for a classic solar installation.

You all seems to base your answers on that, so obviously communication gets complicated.

I needed ballpark numbers for robotics and battery size calculations, napkin figures, to get somewhere to start off of.

I got my answer, as I edited in in the question.

Thanks BTW and sorry if you spent a lot of time trying to help me, I have definitely learned enough to set up solar panels at home on top of it all.
