Solar in Indianapolis starts with hail and the roof you actually have, not a sketch from above. Bungalows bring tired valleys, chimney flashing, and street-tree shade. A newer roof may have a clearer south face and a hot attic under it. Low porches hold snow and should not carry an array. If the shingles are already failing, they come first.
Someone on the roof can see soft deck and flashing that has left the chimney. A sky image cannot. Ask who answers for a leak at a mount and how the array comes off after hail. Old-grid alleys and side gates limit access. One leftover tree can own the southern sun on a new lot. Say whether the basement electrical service is as old as the house.
Name the modules and the inverters. Shade from a chimney or a maple is a different layout problem on a string of modules than on equipment that can isolate a corner. Know who you call when an inverter goes quiet. Say if the gear should be yours. A garage roof is not the house roof, even when it sees more sky. Hail can mark one of them and leave the other.
Permits and permission to operate from the utility are part of the work. Ask who files, and what moves if a hail-damaged slope cannot take the layout. Winter output will not mirror a bright summer, between low sun, cloud, and snow that melts and returns. Say that before install day. Ice shedding off a valley can strike whatever sits below. Skip a roof you already plan to replace.
Say roof age, which way the slope faces, and whether a tree or a neighbor blocks the south. Mention hail marks you can see from the yard. Porch roofs are not spare space for modules. Call the number on this page.
