What are real output from solar panels? [Solved] (lemmy.world)

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 [email protected] ! You all can now continue explaining how many panels a home needs or what a kwh is, Merry Christmas to you all!

This. There is too much local variation in sunlight angle and weather to give a straight answer. An easy method is to take the rated output and multiply by 0.2, but even that is merely a rough average over a year.

But there should be data on weather and climate variations. So theoretically you could include that data into the calculation. Theoretically. Who's gonna do it?

That's what the calculators are for. This has been done.
