I was trekking in Norway this year, hiking from hut to hut.
This is exactly the lifestyle that you experience there:
Burning wood in the oven while having electric light and (usually) enough power to charge your phone.
It was quite the pleasure.
I'm a layman when it comes to solar installations, but I read a bit into the topic, as I want an installation on my balcony next year.
I read that partial shadows on the panels are the worst due to the connection in series of the individual plates. There are rows or even loops connected on a panel and with a part of that connected series covered in shadow, it results in a fraction of the power output. A tiny shadow results in a huge loss.
If that is your garden, you should fix that to avoid shadows onto each other.
