Tesla may have priced their panels below competitors - but probably more in the range of 5-10% - not 38%.
Since our electricity costs $.11/KWh, the break even on a 16KW/4 PW system (which wouldn't provide all of our electricity) would be around 20 years. Removing one PW would reduce that to 18 years. Still much too long, especially considering the warranty would run out for most (if not all) of the components well before we hit break even...
However, if Tesla really had lowered their panel prices by 38% below the current pricing, that would have reduced the break even to 15 years (with 4 PW) or 13 years (with 3 PW), getting closer to a reasonable number in an area with low electric rates.
I think I may be in my home for the next 10 years minimum and I have been considering Solar to offset Power Consumption. I live near the Coast and I am interested in utilizing Powerwall when we have Hurricanes, Power Outages, etc. instead of a Natural Gas Whole House Generator.
I am very interested in the additional Federal Tax Incentives, as I think I could greatly use them this year to offset income tax.
It sounds weird when I think about a "break even" being so far out even though I would hope I would be experiencing benefits along the way. (Reduced Power Bill, Backup Power during outages)
Not arguing with you at all, just very interesting that it takes that long and thought provoking. I found your posts very informative and appreciate you confirming the pricing with Tesla.
