Real World Examples of how Solar STEM can be applied in the classroom.
Crowd funding donations under the Education Tax Credit bill could make the following a reality while lowering school utility bills and preventing tons of carbon from entering the air.
Solar Lesson Plans –
An educational lesson could involve going to the site and seeing the solar system, but there are also many ways to educate students without visiting the site in person. Without requiring a trip to the solar energy system, students could investigate how solar works, how much energy it generates, how it benefits the environment, how to design engineering plans, and how it is mounted to the building.
There are many different courses that could utilize system specification sheets, system design/schematics, actual electricity output data, and system flow diagrams. Mock roofs are common for professional solar installer training courses. They can easily be created to teach solar installation and wiring to students.
Courses such as Chemistry, Physics, Mathematics, Engineering,, and Computer Programing and Software can all utilize an onsite solar energy system safely for classroom education. Some examples include:
PV cells operate because of the flow of electrons. PV modules are made of different elements to take advantage of their varying abilities to release electrons. The heat transfer of fluids in solar thermal relates to chemistry.
The flow of electricity is a physical phenomenon. Different systems will operate at different voltages and amperages. They also have to meet different frequencies depending on the local electric grid to which they are connected.
The design of a solar system involves a great deal of mathematics. Some of the necessary equations can be considered discipline specific. These specific equations will be addressed in the General Engineering section, but they could easily be integrated into many basic mathematics classes as real-world examples.
When designing a solar system, the path of the sun and the local latitude of the system are all considered to determine the optimum module angle or tilt above the horizon, while also placing the modules in such a position that they do not shade each other in a given space.
All engineering disciplines require specific calculations for solar system components, and each discipline is required to develop system schematics for the system design.
Determining loads on the roof resulting from solar system installation, and selecting materials for module manufacturing and mounting materials.
Determining wire sizes, voltages, amperage, predicted wire losses, and outputs. System designs require single or three line electrical diagrams for building department and utility approval.
Engineering and Architecture:
Structural loads on mounting systems, ground penetration considerations, ground bearing loads, and wind loads.
Programing from AC/DC inverter to system display panel that shows electrical output of system, voltage, frequency, and amperage regulation, as well as overall system performance. System designs can be completed in AutoCad, Google SketchUp, and other computer design programs
