Physics Ia Solar Panels

The diagram outlines how.

Physics ia solar panels.

The maximum theoretical power from our solar cell p max is the product of the v oc and i sc. There are 54 panels with a total area of 88 m 2. Traditional energy sources are not the most efficient at converting chemical to electrical energy. The illuminance will be used to determine the actual power of the light incident on the solar panel.

They are aligned to be roughly south facing and tilted to maximise the amount of sunlight they collect. When sunlight shines on solar cells light particles known as photons hits an electron which will cause the electron to bump out from the silicon sheet of solar cells. Hence they are called solar panels. Physics ia linearising the graph solar panels.

Solar panels do not generate electricity but rather they heat up water. Describing the differences between photovoltaic cells and solar heating panels guidance. The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Energy density has units of j m 3 the description of the basic features of nuclear power stations must include the use of control rods moderators and heat exchangers.

The solar radiation per second per m 2 at the top of the earth s atmosphere 1400 w m 2. Physics of how solar works the physics behind this process is actually quite simple and not as complicated as it may seem. That relationship is non linear when plotting power production vxi against the angle of incidence. For my physics ia i m doing power production of a solar panel versus the angle at which light is incident on it.

The name solar panel came from the fact that sun supplies energy to the panels. They cover about half of the roof where they are in full sunlight in order to generate electricity which contributes to the electricity used in the building. These photovoltaic cells electrically connected to each other through a series of strong bonds utilize the photoelectric effect to convert energy from the sun into usable electricity. Albedo of a planet depends on cloud cover ice water color and nature of the soil and latitude.

Up on the roof of the institute of physics building is a small solar farm of solar panels. α e 1. A solar panel is a panel designed to absorb the sunlight for generating electricity. Everyone on earth needs energy and more of it than ever before.

I will also measure the illuminance of light on the solar panel at 2cm intervals with a lux meter. Solar panels are made up of solar cells that are frequently made of two layers of silicon arranged around conductive material. Specific energy has units of j kg 1. They are often located on the roofs of buildings where they can receive heat energy from the sun.
