I suppose it depends on whether space or number of panels is your limiting factor. Hypothetically if you had a hill to build a solar farm on you could cover it in solar panels. But you might have a whole hill and 500 panels so in that case the spacing could play a much bigger factor.

Reply to comment by Grimij in Increasing the spacing of solar panels between rows improves PV system efficiency and economics by allowing airflow to cool down the modules, this could improve a project’s LCOE by as much as 2.15% by giuliomagnifico
