It sounds like you’re in good hands then.
If you can afford to pay the extra then my view is in ten, fifteen years you might be really glad of the extra power your system generates.
The LG 300 is a very cost effective option. Not as expensive as the BenQ’s or Sunpowers but generating more power than the usual 250 panels. We’ve used them a lot on smaller roofs, especially mid terraced ones.
Maybe your final decision will be about aesthetics then, because like you said, “Canadian look the best panel. Nice square block on the roof too.”
25-30 years is a long time to look at them on your home.
Welcome to solar panelled century.
