Solar Energy
Solar panels convert sunlight directly into electricity. Output depends on sunlight intensity, panel area, orientation, and temperature.

Solar panels and power
A solar panel converts a fraction of incoming solar power into electrical power. The instantaneous power output is approximately P = η · A · I, where η is efficiency, A is panel area, and I is solar intensity (irradiance).
✔ Key takeaway: Solar power ≈ η A I; orientation and shading strongly affect output.
Link to simulator: Use the solar energy simulator to vary intensity, angle, and area and see power and daily energy change.
💭 Think about this:
Why can solar panels still generate power on a cloudy day, even though the output is reduced?
