Experiment Shine Light On Solar Panel Measure

Beyond using a good light source you need to align the solar cell toward it properly to get optimal power.

Experiment shine light on solar panel measure. Turn on the flashlight and measure the surface area. Think of it as positioning a sail towards the wind. Connect the ammeter to the solar panel and set the solar panel on a flat surface. 1 place the solar cell on the table directly under the desk lamp and switch on the desk lamp.

By showing how the reflectors scatter light the researchers started to take the risk out of using reflectors with solar panels. 2 connect the solar cell with the electric motor and a dmm to measure current. Record your measurements in the chart below. After 30 minutes carefully transfer the oven thermometer to box 2 and secure the cover.

After completing the procedure allow each oven to cool before dismantling and take caution when handling the light. In the 1880s photovoltaic cells had an efficiency of 1 to 2. 3 record the solar cell current and observe the turn speed of the propeller of the electric motor. A solar panel installation company contacted hanna instruments about measuring light intensity.

The best way i have found to align a solar cell towards the sun it to mount a small stick perpendicular to the solar cell s surface then adjust the cell to minimize the stick s shadow. For best results dim overhead lights in the room before turning on the flashlight. Set the ammeter output so that it will read milli amps ma. Shine the light directly into box 2 and record the temperature rise every five minutes.

Parabolic solar dishes on the other hand concentrate solar thermal energy to drive an engine which in turn drives a generator to create electricity. Today photovoltaic cells can reach an efficiency of 40. Experiment with a dslr or hybrid camera to measure the overall brightness of the sky. Put the camera in manual mode so that you can specify the shutter speed iso and aperture settings.

Your experiment will measure the effect of changing light intensity on power output from the solar cell. Turn off the flashlight. Be sure you will get a reading when you use the bulb with the lowest lumens. The goal of this experiment is to determine how changes in incoming light intensity affect the output of solar cells.

Set up your lamp so that light will shine directly onto the solar panel. A solar panel is made up of many individual photovoltaic cells that convert light to energy. Next rotate the flashlight to a 60 angle 60 solar elevation as shown on the right in figure 4 1. The wavelength of light absorbed by the panel determines how much energy is transferred.

A possible variation would be to investigate the effect of changing the color of the light.
