Im a little torn on this... yes, if your elec bill is $75 or more a month, than having to replace batteries every 5 years is cheaper.
But what about the 8-20K you paid for your initial install ? You would need to have up to a $400 a month electric bill for it to make sense to install.. (20k divided by 60 months.)
