Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Use zero series resistance and infinite shunt resistance, and solve the derivative of power for the MPP.
I(V)=Iph−I0 expm1(V/(nVT)); maximize V I(V) on [0,Voc]
Worked example
The ideal short-circuit current equals the entered photogenerated current, while power is zero at both short/open circuit.
Assumptions and input details
Ideal single-cell model with entered fixed parameters. No irradiance/temperature coefficient inference, module wiring, shadowing, series/shunt loss, actual panel specifications or power guarantee.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Estimate energy and optional electricity value from entered peak-sun hours, combined losses and self-consumption.
Solve a forward Shockley diode and series-resistor DC operating point from entered model parameters.
Compare input energy with useful output over the same time. Find average input/output power, energy loss and conversion efficiency.
