Exactly what my solar installer said. The LG panels are good, as are others , however anyone saying their panels are Tier 1 or European is immediately suspect.
The projects I have designed which involved solar and AC used an earth sourced heat pump for the AC. So it can run all day on solar and heat or cool the house with 20% of the energy required for air sourced systems and turn off at night. It is a very stable temperature under the ground where on a hot day or a cold day you are fighting an expensive thermal problem.
Or leave town for the summer.

LG's newest panels (as on our northern roof) are awesome. They have excellent overcast/low angle performance (80%) and if you are offered anything else say NO. Cheaper Chinese PV panels simply don't cut it IMHO.
