Can someone recommend a cost effective installer for a 2 string 5 panel, 9 panel install on an existing Tesla Powerwall with MPPT-5 and MPPT-6 available? I was looking to install the setup myself but then I found out with the TPO/Leaseback you can get the 30% as long as you pay up front and you wait 5 years to buy... So this seems better on ROI if you can get the 30% that way. The two installers I got quotes from where 14k for a 5.5kw system and 8k for a 4.0kw system. Neither had the leaseback deal.

What is available and can someone point to me towards where a cost effective expansion can be added?
