Solar Panel Light Intensity Experiment

Solar cells are an alternative method for generating electricity directly from sunlight.

Solar panel light intensity experiment.

The effect of intensity on the power of solar cells this experiment involves changing the intensity of light falling on different cells and measuring their power outputs. The effect of solar illuminance or intensity on a photovoltaic panel has been examined. The goal of this experiment is to determine how changes in incoming light intensity affect the output of solar cells. 2 connect the solar cell with the electric motor and a dmm to measure current.

Solar cells mini solar panel power output testing experiment in direct sunlight vs higher intensity light using a fresnel magnifying lens. Your experiment will measure the effect of changing light intensity on power output from the solar cell. Illuminance is synonymous to light intensity. For example a system with 10 kw m 2 incident on the solar cell would be operating at 10 suns or at 10x.

Your experiment will measure the effect of changing light intensity on power output from the solar cell. Higher intensity of light means that there are more photons hitting the surface of the cell per unit area per second. A 5cm 5cm 25cm 2 0 0025m 2. To obtain of solar cell i v characteristics sample was illuminated by reflective lamp with light intensity equal 1000 w m2.

A possible variation would be to investigate the effect of changing the color of the light. 3 change the angle of the solar cell from 0 to 90. The more hit the cell the more rapidly the electrons move across the p n junction so the larger the emf produced. A pv module designed to operate under 1 sun conditions is called a flat plate module while those using concentrated sunlight are called concentrators.

The measurements were performed at 15 25 and 50 0c temperature with highly accurate measuring equipment at the institute of radiation problems of azerbaijan national academy of science. Illuminance is directly proportional to light intensity per. The cell in this experiment measured 5 cm by 5 cm. Use a ruler to measure the active area a of your solar cell see photo below.

In our solar cell experiment we were tasked with experimenting with solar panels and how they function. The light intensity on a solar cell is called the number of suns where 1 sun corresponds to standard illumination at am1 5 or 1 kw m 2. In the first part of the lab we wanted to see how changing the intensity of light affected the amount of electricity produced by the solar cell.
