How Do Different Wavelengths of Light Affect the Energy Production Efficiency of a Solar Panel?

CSEF · 2019 Physics & Astronomy

Hayden A. Barrett, Andrew J. Gonzales, Logan J. Ryan · Clovis East High School, Clovis, Fresno County

Overview

Objectives We wanted to learn how to get the most efficiency out of the production of energy from the solar panel. Methods We used clear, colored films to cover the solar panel. We used a lux meter to measure the amount of lux from the films and sun and we used a battery pack to measure the amount of energy produced by the solar panes. Results The results of our experiment is the red panel used the energy it was given the most efficiently. For the colored filters, the yellow produced the most energy, but the regular sunlight (the control) produced the most energy overall. Conclusions Our results were not supported by the hypothesis. This helps us expand our knowledge by learning that with limited light, the red filter had the best energy efficiency per lux.

Summary statement

This project showed how to produce the most electricity under all conditions of light by using different colored filters to test their energy outcome and energy efficiency.
