Design
The fundamental components of our solar array are: Solar Panels, Micro-Inverters, Enphase Communication Device, Racking, Wiring, EOS



Solar Panel


Our solar panels were heavily considered, click here for the htm Excel spreadsheet of the specifications of our top five panels considered. We chose the Kyocera panel because it is the best choice of the five for the aspects which we considered heavily. These aspects are highlighted in colors. We are mounting 10 of these panels for our array.

Micro-Inverters


We use inverters to convert the Direct Current (DC) output of the solar panels to Alternating Current (AC) which is used for powering campus. There are two types of inverters, Micro-Inverters and Central Inverters. There are pros and cons to both. However, we chose micro-inverters for the main reason that we can wire it a lot easier with how we have our solar array designed. Additionally, the best reason to use micro-inverters is to create an easily expandable array. And, if for some reason a panel or micro-inverter fails, the entire system doesn't go down as well.

Enphase Communication Device


A web server communications box will gather the voltage and current readings from the data acquisition modules and calculate the instantaneous power produced. The calculation will be stored in the communication box for future reference and pushed to the public website. At any time, the system manager can review the data stored on the server. Data can be displayed by minute, hour, day, month, and year. Graphs can show power produce by each panel and compared over time.

Racking


The racking for our solar array is what holds the solar panels and micro-inverters in one place, and at an any of our desired angles. The solar array mount is made of rectangular steel tubing, which is the optimal for help with adjusting the angle of the panels. Rather than having one large structure fabricated that would span a width of over thirty feet, three separate structures will be made up and then pieced together with various nuts, bolts and steel plates.

Wiring


Wiring is as fundamental as any of the other components, because without wiring, nothing can be connected! The wiring of our design can be seen in the overall layout of the solar array.

EOS


The EOS box and software is what we are using to report the data of the array to the website. The box measures the necessary components such as voltage, amperage, power, etc that can be used to create several graphs.
