Land per sqft is usually a lot more expensive than panels.

Bifacial above ground capture more of solar, esp if the ground reflects solar back.

Many YouTube experiments where people have captured an extra 100-150W from back panels yielding 500W+ per panel.

And bifacial is only slightly more expensive than mono panels. With higher efficiency the price is worth it.

For residential solar with batteries, the price of panels is barely 10% of the cost. Labor, permitting, connectors, inverters, framing take a huge chunk of the cost.

I imagine utility scale has lower overhead but the tradeoff for bifacial would have given positive ROI.
