I’m 9.6 once you figure in CenterPoint charges.Great in concept. I can only buy energy from the city and they don't offer any type of tiered plan.
I've already looked at the average & peak usages that is where the size of system comes from. If I could shop companies like my neighbors down the road in Houston I likely wouldn't be shopping solar as they can often get it as low as 6-7 cents/kwh.
