I diy installed a 13kw ground mount with a 32kwh battery for $18,700 before the tax rebate last december. 6 year payback at my current rate of $0.12 kwh after the rebate. Its a complete no brainer at this point.

6 years to recoup your costs on a depreciating asset is maybe not such a good investment that it becomes a no brainer. It's an OK investment, but the money can probably be invested better.
