One of the most unfortunate mistakes made in PV system design is the flat mounted array. You should ALWAYS mount modules in a tilted configuration. Lets explore the benefits of the tilted array…
1) More power production results from better sun angle - Modules tilted up toward the southern horizon in the northern hemisphere (or towards the north in the southern hemisphere) will produce considerably more power than modules that are flat.
2) Sheeting of rain water promotes module cleaning - Tilting your array promotes sheeting of rain to clean the modules. Flat modules are a wonderful catch basin and turn into a a shallow puddle every time it rains. An even bigger problem can result (more…)
