I use geothermal heat pumps, which provide a cooling SEER of 35+ and a heating COP of 4+. And get free hot water all summer and about 1/2 of my hot water needs in the winter from the GT heat pumps. My 12 kW array and heat pumps is a great match for this. But I am REALLY looking at adding an EV and another 4 kW to the solar array.

For me it comes down to the 2018 LEAF and Chevy Bolt. The 2018 Leaf should be released soon.

Indeed, an exciting time!
