We love having the solar. A gift from my in-laws. 5KW all up. Takes up roof space, but its not like we were using it for anything else.
We do most energy intensive stuff during the day, just lights and screens at night.
Not sure how long the panels last, but so far so good.
It's really a great thing to have and my only issue is that I didn't get an array fifteen years ago. That's so cool you got yours gifted...my second system was a government scheme that the household was eligible for that has paid incredible dividends.
