PVSTOP Coverage Calculator — Estimate Report

System Size

If you know your system's string and combiner configuration, entering it here provides a more accurate per-zone breakdown of PVSTOP requirements.

Panels per String

Panels per String:
The number of solar panels connected in series within a single string. Typically 10–30 panels depending on system design and inverter voltage window.

Strings per Combiner

Strings per Combiner / Inverter:
The number of strings feeding into each combiner box or inverter. This defines a coverage zone — effective 40% coating of panels within each string eliminates current flow, stopping power generation for that string.

Combiner Groups

Total Combiner Groups:
The total number of combiner boxes or inverters across the entire installation. Each group represents a distinct coverage zone for PVSTOP deployment planning.

Assumptions: ~500W panels, ~2m² per panel, practical coverage rate of 4m²/litre (conservative field-tested rate). Actual requirements vary based on panel specifications and site conditions.
