This especially makes sense these days now that (in most places) you can only sell your solar at bulk rates which are lower than the electricity you buy. So you literally get your energy sold back to you at a premium for the sole service of storage which is a rather crap deal. Keeping all the power you produce seems like the best option, though you do have to pay for the initial cost of batteries. It would be neat to see some numbers as to how long it would take to make up the cost back in monthly bill reductions depending on the local prices. |

Here in NM, that's true if you literally sell your surplus solar. But if you allow PNM to "bank" it, you receive kW for kW back what you put in, when you need it (e.g. during the dramatically colder winters here in northern NM).
