|
The hardware repository for our solar simulator for testing 1U solar panels
|
|

|
|
|
|
## General Information
|
|
|
|
The OreSat Solar Simulator is a benchtop simulator for hardware-in-the-loop testing of CubeSat solar modules. It uses LED and halogen light bulbs to emit light that simulates the sun's solar spectrum in low Earth orbit (Air Mass 0 or 'AM0').
|
|
|
|
The work for this was done as an MCECS Capstone Project from January to June of 2023 by Bendjy Faurestal, Adam Martinez, Cesar Ordaz-Coronel, and Charles Nasser. Andrew Greenberg was both representing PSAS as the Industry Sponsor and the Faculty Advisor to the students.

|
|
## Hardware
|
|
|
|
|
|
|
|
The schematic and pcb layout were designed in [kiCADv7](https://www.kicad.org/download/). The boards we used were fabricated by [OSHPark](https://oshpark.com/) in Lake Oswego, OR.
|
|
|
|
The simulators are driven by a PocketBeagle Rev. A2b attached to the board.
|
|
|
|
## Software
|
|
|
|
The software for this project lives in the [oresat-solar-simulator-software](https://github.com/oresat/oresat-solar-simulator-software) repository.
|
|
|
|
## Mechanical
|
|
|
|
The mechanical components were developed by Zeus Ayala using onShape.
