I don’t have them on my home because my HOA disallows them. I did, however, initiate and helped manage installation of systems on 3 separate family members’ homes and since I had already done the research and the financial benefit worked out for each of them. One was 6 years ago, one was 3 years ago, and one was 2 years ago and none of them have any complaints.
The 6 yr old system is almost paid off and has already reached its pay-off value since electricity prices keep rising… meaning, they haven’t paid off the system, but would have spent more in electricity in the 6 years they have had it if they would not have installed it.
I am currently in the process of moving out of a neighborhood with an HOA and plan on installing a system as soon as I get into my new home.
