Solar in Missouri has to respect two skies. Western lots see hail and open wind. River and Ozark lots see storms, humidity, and trees that steal the south. The roof deck comes before modules. A bruised or soft slope is not a platform. An array adds uplift when wind gets under the rails and adds a glass face hail can mark. Say which part of the state the building is in before you describe the sun.
Say what stands south of the ridge: a barn, a neighbor, a hardwood line. Summer leaves and bare winter limbs are different shade. A hip, a gable, and a metal farm roof are different mounts. Fasteners have to reach structure. Penetrations have to survive a driving rain. Low pitch holds debris and snow in the north. The surface has to take screws without becoming the next leak.
If the roof is due, replace it in an order that installs once. Marked glass and a hail-bruised mat should be named separately, and both matter more on the western open ground than in a shaded hollow. Animals use the warm gap; if you already hear them, say so. An inverter needs air in this humidity. A closed attic is a poor closet. Say if the electrical panel is old or full.
A house and a barn may not share equipment. Name the building. Output changes between a bright summer and a week of storm cloud or snow. Say whether snow will be cleared or left, where snow is even part of the year. Do not describe a north slope under oaks as an open south face. Wind tie-down matters on the same ridges that take storms.
Lead with the roof, the shade, and whether hail or wind has already marked it. Name the town. Missouri weather will test whatever you fasten. Call the number on this page.
