I live in one of the most regressive states (Alabama) in the US when it comes to solar power. The net metering is only at the wholesale price which is about 1/3 the residential rate of ~ $ .095 kWh. There is also a fee of $5 per installed solar kWh per month to be connected to the grid as a backup. Here is the link to the rate rider document if you care to read it: http://www.alabamapower.com/content/dam/alabamapower/Rates/RGB.pdf As bad as the solar situation is, I'm wondering if I could take advantage of my power company's Time of Use (TOU) rate. I can get a steep discount on my typical kWh rate of $.095 down to $.055 for most of the year. The kicker is I would pay $.255 per kWh during the months of June - September from the hours of 1pm - 7pm. These are the prime hours when we need to run our heat pump for cooling. Here'e the link to the rate document: http://www.alabamapower.com/content/dam/alabamapower/Rates/RTA_Energy.pdf When the PowerWall is used as a TOU only system, is there a configuration where it could be the sole source to the house until the power is depleted, to stay off the $.255 rate as long as possible during that June to September period? Then power switches back to the power company? Thanks in advance for the feedback.
