Be sure you have enough power when upgrading solar panels to solar towers and enough storage when upgrading that.
Also be sure to watch your population and jobs that are open. Never let there be more people than there are jobs, or twice as many jobs as there are people.
If for the first paragraph, if there's not enough power provided by non-solar buildings, the all of the buildings would shut down due to power shortage.
If the storage is less then the resources you have, first the resources would stopped to be produced, then if you have the resources 10k above the storage limit, then it would start decaying and you will start loosing the resource.
Now having jobs less than housing, you will face the education bug and your approval would drop due to uneducated
