19. Solar Panel Impedance Matching

20. Solar panel laboratory background
Photovoltaic (solar) cells convert light energy in electrical energy (power).

21. Solar panel laboratory background
Photovoltaic (solar) cells convert light energy in electrical energy (power).
Power (P) = Voltage (V) times Current (I)

22. Solar panel laboratory background
Photovoltaic (solar) cells convert light energy in electrical energy (power).
Power (P) = Voltage (V) times Current (I)
Voltage (V) = Current (I) times Resistance (R) (Ohm’s law)
