A 1kW system is horribly inefficient. That's 4 modules, which even in series is not going to get you to grid voltage so you will have to use costly microinverters. Plus you have all the fixed costs of installation, inspection, switchgear, etc. that has to be amortized over a tiny amount of power. Silly. For most circumstances, 4-5kW is going to be the minimum economical installation. There are many people who know how to evaluate a particular site and customer needs to figure out what is and is not economical and how to accomplish that. The mayor, and you, probably are not among them.

This is why politicians need to stay away and let the market do its job. It's too easy to let ignorance or some temporary set of circumstances lead you to impose costly and harmful regulations with far-reaching effects.
