Solar in Tennessee has to pick a ridge, a basin roof, or a hot western plane. Eastern sites add snow and ice load and steeper metal or shingle pitches among hardwoods. Basin roofs see hail, wind, and shade from cedars and oaks on hills that do not face the same way. Western roofs see longer, harsher sun, thunderstorms, and heat that ages the covering under the array. A sky drawing has not felt the deck or opened the service. Ask for a person up there. The three divisions do not share a mounting habit.
Renew a tired covering before anchors go down. Ask how each anchor is closed against water, and who comes back if a leak shows after ice, hail, or a line of storms. Ask how the modules come off when the covering is due again. A steep cabin roof and a low western ranch are different attachments. Chopped roofs on older city houses shrink the area. A simple plane does not. Shade from a neighbor hardwood is a morning fact, not a footnote.
Name the modules and the inverter. Say if electronics live on each module or in one box, and who sees that production dropped. Older services in all three divisions can be too small for a backfed breaker and a disconnect. Learn that before rails go up. Ownership sits in the same conversation: who keeps the equipment, and who removes it so the deck can be opened. Wind in the basin and west belongs in the tie-down talk. Snow in the east belongs there too.
Permits and interconnection are the work. Ask who files them and whether the array stays dark until the utility allows it to run. Skip any monthly-account tale. Useful subjects are structure, flashing, shade, the weather load of that division, and the hardware names. Do not drag a coastal salt spec into the mountains, or a snow spec into a delta ranch, unless the site itself demands it.
Say the grand division, the roof age, and what shades the sunny face. Solar in Tennessee is three site problems, not one southern brochure. Call the number on this page.
