Halfway through upgrading panels after 10 years. Nothing wrong with old but check out the progress:
New ones on left are 650W/panel, old ones are 250W/panel. New are 2330x1135, old are 1600x1000, . That's 155 vs 245W/m²
Both cost roughly NZ$200 each, although I got a really really good deal back in the day on the old ones.
Tell me why this government is building an LNG terminal again?
