How the calculation works
Fasteners are estimated from panel count, support rows, screws per support and waste.
What to verify
Always use the panel manufacturer’s tested fastening pattern and wind-zone requirements.
How accurate is this calculator?
It is a transparent planning calculation based on the entered values and stated assumptions. Verify inputs and obtain professional or supplier confirmation where the decision is consequential.
Does it use U.S. defaults?
Yes. U.S. units, terminology, pricing conventions and rules are the primary defaults where location matters.
Is data sent to a server?
No. The calculation runs locally in the browser and does not send entered values to a remote calculation service.
