I don't live in FL and don't know what rebates, etc. incentives, they offer, but that price for 10kw is not believable unless he's buying a used system that someone desperately wants to get rid of. Even then, it's highly unlikely and even if FL's rebates are extremely good, it is STILL unlikely. More power to him if it is accurate, but I doubt it. He's either mistaken or pulling your leg. MAYBE a 1 kw system if he's doing his own installation. Maybe.
