Use the simulation in your science or Physics class to illustrate conversion of solar energy to electricity
A house with eight solar panels on a south-facing roof, a yellow Sun high in the sky, and a cloud sitting between the two.
Two sliders control everything: Sunlight (0–100%) and Cloud (None → Storm cloud). Four weather buttons jump to preset conditions.
As you change them, you watch beams of light fall from the Sun onto the roof — thinning out as cloud thickens — the panel glass brighten or dull, charge run down the cable to the meter, and the house windows dim. The sky greys over with the light.
A large board in the garden carries the only numbers: LIGHT IN (W/m²) and ELECTRICITY OUT (W, with a bar out of 2000 W).
The physics: power = light on panels × 10 m² × 20% efficiency. Full midday sun gives 2000 W; halve the light and you halve the power; a storm cloud cuts it to 164 W.
Full Adapt accessibility suite behind the header button — Irlen overlays, colour-blindness filters, dark navy theme, projector mode, reduce motion, buttons-only, and a “show the working” toggle that adds the equation to the board.
