Solar decision guide

Is my roof good for solar?

Your roof may be suitable if it has clear, usable area with limited shade and a productive orientation. About 65% of U.S. rooftops pass the broad technical test, but the address-level details decide it.

What the free roof check inspects

Orientation: which roof planes face productive directions.

Shading: where trees, nearby structures, and roof features reduce exposure.

Roof area: whether enough contiguous space remains for a practical array.

Frequently asked questions

What makes a roof good for solar?

The core checks are orientation, shading throughout the day, and enough contiguous roof area for a useful array.

How much clear roof area does one panel need?

A typical panel needs about 17.5 square feet; a useful small array needs roughly 88 square feet before spacing and setbacks.

Does every technically viable roof make financial sense?

No. Roof suitability and financial value are separate questions. Electricity use, rates, system cost, and export terms also matter.
