Solar & Wind Site for a groundwater flow

Built for k-12 students learning it in middle or high school. Watch the idea come alive with plain-language steps and everyday examples — perfect for projects and homework. Simulate a groundwater flow live below — adjust the inputs and watch it respond, right in your browser.

Solar PV SystemLive

Presets

A solar array's output is its rated power (area × efficiency at 1000 W/m²) multiplied by the peak sun hours your location receives — the equivalent full-intensity hours per day. Tilt matters too: aiming the panels near your latitude maximizes annual yield. Real systems lose a bit more to heat, wiring, and inverters.

System rating4.0 kW
Daily energy19.2 kWh
Annual energy6996 kWh
Homes powered0.7

Governing equation

Reading this result: A 4.0 kW array in 5-sun-hour sun yields about 19.2 kWh/day — roughly 0.7 average homes.

Wind Turbine PowerLive

Controls

Presets

Wind power scales with the cube of wind speed and the square of rotor diameter — which is why turbines keep getting bigger and why a windy site is worth so much more. No turbine can extract more than 59.3% of the wind's energy (the Betz limit); real machines reach about 45%. Below cut-in and above cut-out speeds they produce nothing.

▶ Run in Python

Data Inspector

Power output1.64 MW
Rated power2.83 MW
Swept area6362 m²
% of Betz limit71%

Governing equation

Reading this result: In the ramp region power climbs with the cube of wind speed, so even a small gust adds a large jump in output.
