Physics Ia Solar Panels

The solar panels generate electricity as long the sun hits the solar panels.

Physics ia solar panels.

The sun provides energy into solar panels and it is then converted into electricity to power your home but how does this process. To linearise it i tried to plot vxi against sin of the angle. Use a ruler to measure the active area a of your solar cell see photo below. 01 simplify square roots with factor trees in algebra radical expressions part 1 duration.

α e 1. As you ve seen above i get around 3 4 emails a day from ib physics student asking for physics ia ideas. While total photovoltaic energy production is minuscule it is likely to increase as fossil fuel resources shrink. Physics behind solar pv and how solar panels work.

For my physics ia i m doing power production of a solar panel versus the angle at which light is incident on it. The ratio of the power of radiation scattered from the body to the total power incident on a body relationship between albedo and emissivity. In fact calculations based on the world s projected energy consumption by 2030 suggest that global energy demands would be fulfilled by solar panels operating at 20 percent efficiency and covering only about 496 805 square km 191 817 square miles of earth s surface. In this week s livestream patrick and andrew will explain how solar panels work and the basic physics involved behind photovoltaic pv solar.

The solar intensity from the sun s i over a given area at the surface of the earth is approximately 1 000 watts m 2. The solar radiation per second per m 2 at the top of the earth s atmosphere 1400 w m 2. There are a number of physics topics that relate directly to the core principles underlying the development of solar panels. Albedo of a planet depends on cloud cover ice water color and nature of the soil and latitude.

With growing interest in the field of renewable energy this may be a good opportunity to introduce your students to real world applications of principles covered in class. First calculate the solar power arriving at the solar cell by multiplying the intensity of the sun by the area of the solar cell. The higher the rate of photons striking the solar cell the more power it can produce. The electricity generated is multiplied by the number of solar cells in each solar panel and the number of solar panels in each solar array.

That relationship is non linear when plotting power production vxi against the angle of incidence. Math and science 81 311 views. So in this case my general topic of interest would be.
