yes, and sometimes it's a positive effect.

source is e.g. https://theconversation.com/how-shading-crops-with-solar-pan...

A lot of crops actually yield better in partial shade and are grown in open fields as shading is more expensive than the yield penalty.

Unless you're planting energy crops like corn or canola, that aspect tends to be still net-positive even if perhaps a bit of the solar yield has to pay off a minor reduction in crop yield.

Notably though grazing pasture mostly doesn't complain and if mounted suitably (IIUC low enough density and high enough start above the ground), it can co-exist with effective nature preserves.
