Practical course on Photovoltaic Solar Power

Explore how current flows when charged particles move, comparing conductors like copper with insulators, and explain short circuits, air gaps, and charge differences in practical solar power contexts.

Explore how current and voltage drive charge flow in conductors, measured in amps, and how solar panels create a voltage difference that governs electron movement.

Explore the difference between AC and DC current in solar systems, including how voltage, current, and power behave, and see how DC components, inverters, and charge controllers enable AC appliances.

Select cables by considering thickness, material, insulation, and voltage, as proximity to other cables and electromagnetic effects influence current capacity.

Explore solar panel connectors, including male and female connectors, wire preparation, and cable selections; measure voltages and assess losses from cable resistance and inverter efficiency.

Explore kilowatt hours as energy; apply P = V I to show 1 kW for 1 hour equals 1 kWh, with a washing machine’s peak and average 0.5–1.5 kW.

Explore how kilowatt hours and amp-hours relate, compute energy with a 12-volt, 100 Ah battery (1.2 kWh), and understand how discharge rate (C-rate) affects usable energy and battery life.

Learn how to select solar panels by assessing peak power, operating voltage, and current, and consulting datasheets for open-circuit voltage and efficiency to fit your system.

Analyze a six-panel 2s3p photovoltaic array to determine a 60-volt output and 27-amp current, yielding 1.62 kilowatts of power.

Learn to assess true battery capacity using c-rates (c-20), balance depth of discharge, and select solar battery types like lead acid with proper charge regulation for photovoltaic systems.

The inverter converts DC from solar panels to AC for appliances, regulating voltage and battery charging within an integrated unit. It discusses DC versus AC, sine waves, and heat risks.
