This was expected. When solar panels were expensive, you had to optimize for output. When you get the same rate for any kWh, you optimize for output. Now that PV is cheap as fuck, of course, there’s going to overproduction.

Now the dynamic will change. Instead of facing south, it becomes attractive to orient east/west. This generates more output on mornings or evenings. As a next step, you add batteries to the mix. Yes, they said they were expensive, need rare materials, and yadda yadda; except with lower prices every month, solar batteries are thing now.

Also “overproduction” is relative. Most of our heating and transport is fossil. There’s a long way to go.
