In NV it has really depended on the type of solar but seems anything that takes up large acres of land is going to be an issue. For ground based solar cell arrays we've had issues with the desert tortoise and other animals that it encroaches on their habitat. When you are using the molten salt method the bird population ends up at risk due to the laser like beam of light that gets directed towards the tower. They go so far as to deploy hawks and sounds but inevitably some bird brain gets fried.
There is nothing of meaningful physical scale that can be built that doesn't encroach on some animals habitat. There are no exceptions, whether we're talking about a house, a road, a store, a factory, a power plant, a train line, a commercial office building.
Humans only have two choices: de facto suicide, or encroach.
There is plenty of desert and piles of garbage which are great for building solar panels on.
Another aspect often overlooked is shade is very important, there are methods where building solar panels can actually help the environment by providing much needed shade.
You can also build solar panels of the water, theoretically you could build solar panels suspended in the air.
And they don't really require much to hold them down, compared to a wind turbine which needs to basically be a tree.
We just don't try. There is no effort to experiment because everyone is scared to change.
