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!

For a house of 6 people we installed 5kWh which is basically perfect for them, but they are also very resourceful with their electricity usage, running washing, cleaning and cooking during the day as to not drain the battery at night.

But yeah if you dont get enough sun in your area its just a waste of money. My parents system will be payed off after 11 years if the sun stays at the level it has been at for the past 2 years.

Predicting how import vs export costs might develop is also a big factor
