Enter system voltage, system leakage, TX pulse (current / duration / per-day count) and working lux. The tool auto-averages the current and evaluates required OPV area, harvesting IC, storage and cold-start feasibility.
Illumination environment (assumption)This evaluator defaults to 10 hours of effective indoor illumination per day when sizing the OPV area: the panel must harvest the full 24h system energy within a 10h light window, so OPV area = average power × 24 ÷ (power density × illumination hours). If your actual exposure differs (e.g. low-light scenarios), adjust “Daily illumination hours (h)” below — results recompute live. Storage / no-light redundancy still uses 24h of daily consumption as the dark-period buffer.
Inputs
+2 µA (auto)
Default 10h effective indoor illumination; OPV area is sized to this.
Fill the inputs and click Evaluate to get recommended OPV area, IC, storage and cold-start verdict.
