Still not seeing $59k.
2.3 * 30.000 * 0.7 = $48,300 (30% tax credit)
2.3 * 30.000 * 0.5 = $34,500 (50% cheaper)
Total = $82,800
Regardless, adding up the cost of the second one in 30 years doesn't make sense for calculating kWh prices, depreciation and cost of capital are the only factors that matter and you are only including one of those.
- aoeusnth1 8y agoSure, looking at my spreadsheet I also discounted the cost by the same interest rate after 30 years, (1/1.04)^30. Agreed that including the second system doesn't really make much sense, but I wanted a quick-and-dirty estimate without having to individually discount each year's production (as you would if you had a finite time horizon).
