CALCULATORS / ELECTRICAL

Solar and renewable energy

Location/weather inputs or explicitly selected irradiation assumptions.

rated power, irradiance, temperature, losses → power, daily energy estimate

daily demand, resource assumption, system losses → required array rating, area

daily load, autonomy days, solar resource, efficiency → array rating, usable storage

latitude, date/time, surface tilt and azimuth → incidence geometry, relative exposure

module voltage data, temperature coefficients, temperature bounds → string voltage interval, count constraints

collector area, irradiance, efficiency model, demand → heat collected, water-temperature rise

air density, rotor area, wind speed, power coefficient → conditional shaft and electrical power

flow, usable head, efficiencies → hydraulic and electrical power

time-series generation, loads, storage limits → state of energy, unmet demand, curtailment
