Quality pollinator habitat can be created beneath solar arrays. In an Oregon experiment, researchers found that pollinator abundance, diversity, and richness as well as pollinator-flower visitation rates were similar in plots in full sun (without solar arrays) and those in partial shade (under solar arrays). Areas of partial shade under the arrays had increased floral abundance and delayed bloom timing, which could support late-season foragers in water-limited ecosystems.
