Use sun charts to determine solar elevation and shadow angles for row spacing, considering latitude, longitude, time zone, hemisphere-specific date, and azimuth corrections for panel alignment.

Calculate the PV string maximum voltage. Account for open-circuit voltage at minimum temperatures and keep the total series voltage at or below 600 volts, using the module’s temperature coefficient.

The hybrid photovoltaic thermal panel converts sunlight to electricity and heats water via a back-side heat exchanger, lowering panel temperature and increasing efficiency, with a 5–15% electricity gain.

Maximize power with mppt charge controllers by adjusting panel voltage to the maximum power point, delivering 94–98% efficiency and 10–30% more charging power than pwm, and allowing higher input voltages.

Explain how inverters convert DC from solar panels or batteries to AC for home loads, compare pure and modified sine waves, grid-tie, off-grid, hybrid systems, and MPPT.

Compare vertical axis and horizontal axis wind turbines by axis of rotation and height, then show horizontal axis turbines are used commercially for electricity generation.

Learn how wind power scales with air density, turbine swept area, and the cube of wind velocity, deriving P = 1/2 rho A v^3 and using anemometers to measure speed.

Explore how wind thrust on rotor blades produces torque and power, and how the tip speed ratio governs wind turbine efficiency via Cp and Ct.
