Twelve months of real usage shows what your home needs and which charges solar can actually reduce.

No two roofs produce the same power, even on the same street. A south-facing plane in full sun and a west-facing one under a maple can differ by hundreds of kilowatt-hours a year. Pitch changes how panels catch low winter sun, dormers and vents decide where they can sit at all, and your utility's rules shape how extra power gets credited back.
That's why your design starts with your actual roof: measured, mapped, and shaded hour by hour, not a template. Your plan shows how each factor moves the numbers, and if part of the roof isn't worth covering, you'll see that too. Nothing gets smoothed over.
