My SDG+E bill averages $225, of which about $185 is electric.
SDG+E’s rates, for tiers 1-4 are (where I live): 17/20/37/39 cents/kwh. That’s a big jump from tier 2 to tier 3. If you’re staying in tiers 1 and 2, it might not be a no brainer.
For me, it’ll pay for itself in about 6 years, and I’ll have free or almost free electric for at least another 19 years after that.
That’s a pretty hard return to beat, especially with basically a sure thing.
