I switched over to TOU (RTR-1 Residential Time of Use Rider) from RS-1 Residential Service about two months ago. Haven't done an in-depth cost analysis yet but so far looks good. We basically changed our car charging and running the dishwasher to evening hours and washing/drying to weekends. It didn't create any kind of a hardship on our part. Finally found the right person at FPL to talk to about it as the several that I talked to tried to talk me out of it as they were under the impression that it was set up for businesses only. You need to contact Tammy Franklin 1-800-749.2285 extension 25. She will do a cost analysis for you. She did one on us and it came out looking real good so we switched over. There is a $11.90 a month charge for the meter and you can opt out of the program anytime with out charge.
I used Brevard Solar, talk to Jim Spann the owner and let him know Mike Z referred you. Great people to work with and have done more than 1000 systems to date. They did my original install (10Kw system) 4 years ago and added another 5Kw last year.
