Use a clearly defined load.
Enter constant voltage and current at the same load and a duration. This calculator gives P = V × I, E = P × t, and Q = I × t. It does not infer efficiency, a biological cause, or whole-system net energy.
What do your measurements imply?
For constant voltage and current at the same load: P = V × I; E = P × t; Q = I × t. For changing signals, integrate synchronized measurements instead.
Enter your own values. No Helios measurements are preloaded.
No efficiency, net-generation, biological-attribution, or independent validation conclusion follows from this calculation.
When this calculation is not enough.
For time-varying signals, energy requires the integral of synchronized V(t) × I(t), not simply the product of independent average readings. Open-circuit voltage should not be multiplied by a short-circuit current as if both occurred at one operating point.
External bias, illumination, pumps, electronics, stored charge, and consumable chemistry may matter in a system-level balance. This calculator has no input record for those contributions and deliberately does not calculate net generation.
No Helios One performance data are preloaded. An example appears only when you choose the explicitly labeled example button.
What it means for Helios.
The current Helios announcement reports an initial electrical response. The instrument mode and values are not published here, so this tool must not be used to invent a corresponding power figure.
