PV Partial Shading Calculator: Bypass Diodes and Optimizers
Wired White v1 Sweep a shadow across solar cells and watch the P–V peaks change. Compare bypass diodes, global or local MPPT, and module optimizer power after conversion losses.
Solar and wind
Solar and wind energy calcs: balcony power plants, PV with home batteries, off-grid systems, sun position and wind-turbine yield. Neutral estimates that name the rules and data they use.
Wired White v1 
Solar Inverter Oversizing: DC/AC Ratio and Clipping Loss
Wired White v1 Compare solar DC/AC ratios, annual yield and added-panel payback. Separate MPPT current loss, inverter clipping and grid export curtailment, with an east–west option.
Solar Water Pump Size Calculator & Borehole Sizing
Wired White v1 Size a solar water pump from daily demand, borehole drawdown and pipe losses. Estimate PV kWp, pump horsepower, hourly flow and intake submergence.
PV String Sizing Calculator for Cold Mornings
Wired White v1 Check cold-morning PV string voltage against the inverter’s hard DC limit, hot MPPT voltage, current and DC/AC ratio. Animate a temperature-dependent I–V curve.
PV Single-Diode Model: Datasheet I-V Curves and MPPT
Wired White v1 Build a PV module I-V and P-V curve family from datasheet points. Scale a matched array and animate P&O or incremental conductance MPPT with voltage-step and sampling trade-offs.
Off-Grid Solar System Sizing Calculator
Wired White v1 Size an off-grid solar array, battery bank, MPPT or PWM controller and inverter from daily loads, sunless days and worst-month peak sun hours.
