Is solar panel voltage constant? Why does the voltage change if the intensity of the lighting changes?
Homework Answers
No. the solar panel produces the voltage as a result of photoelectric effect, that is when the radiation incident on the surface electrons get ejected and which constitute a current. the number of electrons gets ejected from the metal surface is proportional to the intensity of radiation. so, as the intensity of light changes voltage changes.

A satellite in Earth orbit maintains a panel of solar cells of area 4.59 m2 perpendicular to the direction of the Sun's light rays. The intensity of the light at the panel is 1.57 kW/m2. (a) At what rate does solar energy arrive at the panel? (b) At what rate are solar photons absorbed by the panel? Assume that the solar radiation is monochromatic, with a wavelength of 550 nm, and that all the solar radiation striking the panel is...

A solar panel measures 0.58 m by 1.8 m. In direct sunlight, the panel delivers 6.8 A at 4.2 V. If the intensity of sunlight is 300 W/m2, what is the efficiency, as a percentage, of the solar panel in converting solar energy into electrical energy?

Solar panel: Boost converter Solar panels turn sunlight into electricity, but they normally protest being connected to high-resistance loads, like say a heating pad for my sore back. The solar panel will stop working if the voltage across its terminals, V., would be greater than 30 volts. To fix this, we put a "boost converter" between the source and the load, which transforms the solar panel from a low-voltage-high-current machine into a high-voltage-low-current machine. Boost Converter Solar Panel CopperCoil la...

Emitter Follower Application Circuit A simple voltage regulator circuit can be constructed using an emitter follower and a zener diode, as shown in figure 4. For this specific application, we would like to power a 12 Volt DC water pump from a solar panel. This type of application is quite common when the location of the water source is significantly far from power lines. The voltage from the solar panel varies...
