Different varieties of the same crop vary significantly in their solar reflectivity (called 'albedo'), so selecting varieties that are more reflective will enhance this cooling effect.

This article has reviewed the basic principle of solar heat reflective coatings, the relationship of heat reflectivity with binder and pigments, and the tester and calculation of heat reflectivity.

The thermal performance of the solar pond decreases with increasing the bottom reflectivity when the water turbidity is constant.
