Currently, the best option for removing the build up is teams with handheld brushes and cleaning fluid which is time consuming and requires extra labor. # Solution Our idea to make this an automated task is to take data from the power output of the solar panel and from this determine the necessity to clean it. We will be using a current meter to monitor the output current from the solar cell and a cleaning system that can be either wash and wipe or just wipe that is told to clean from a remote location. The system will also be able to clear blockage on the solar panel like snow or animals via a notification being sent to a supervisor’s or customer’s phone that a wipe may be necessary. # Solution Components ## Current Meter From the current meter we will be able to determine the output of the solar cell and depending on the threshold that we want to set, as losing enough power that is more than the power it takes to clean, will allow us to see it as reasonable to clean. Data of the solar panel output will also be tracked to detect build-up over the course of several hours/days. ## Motors We will use the motors to move a wiper up and down the solar panel to clean off anything that is obstructing the solar panel. ## Microcontroller A microcontroller will be used to gather data from the current meters and calculate the chance that dust or other debris is blocking the solar panel and will activate the cleaning system made up of the sprinkler, motors and wipers. From the decrease in current we are able to determine the efficiency drop once the efficiency drops so much the cleaning process will be initiated. ## Water pump and sprinkler This will be used to spray, when told to either automatically from output data and microcontroller or remotely by the owner/user, a cleaning solution before the wiper is initiated to allow for cleaning of dust off of the solar panel. ## Battery system to power cleaning system With the battery system it will be charged from the solar panel in a way that does not significantly impact the power output and when fully charged it will remain until it needs to be used to power the cleaning system. ## Remote access to collected data With remote access to the data we will be able, from any location, to get an alert when the power reaches a threshold, determined by us and the tradeoff power.This will allow us to make sure that the system is cleaning properly and that the solar panel is returned to normal power output. # Criterion for success Energy output after cleaning is 25% to 35% greater than the output before the cleaning process Energy output of the solar panel is significantly greater than energy consumed by our system Owner/User gets real-time notifications about electric degradation Ability to request wiper motion from remote locations. |
