 PDR Feedback
   Lack of / Unclear Application
   Poor wireless transmission near water
        No longer near water
   How do we plan to demo this?
   How do we test this?

 Back to the Drawing Board
     Same general device, new application
     We consulted with our advisor
     We came up with a solar energy sensor and calculator
     Current calculations for solar panel installations
       • Very accurate, within ~5-6% of actual power with weather
         and shading calculations
       • Industry standard tools like the Solmetric Suneye and
         PVWatts.com
       • Design and installation can be very expensive
   Our new device will give real time data, optimization, and
    dollar value feedback to the customer
   Our device will attempt to be just as accurate but be a new
    cheaper technology alternative

 Lack of / Unclear Application
   Solar power can be expensive
       • Know the power savings prior to installation
       • Incentive to install solar panels
   Uncertainty of efficiency
       • Performance is rated under standard test conditions irradiance
         and temperature
   Uncertainty of optimal product to purchase
       • Calculator will rate multiple products on the market for the
         user’s reference
   Errors in Placement and Orientation
       • Actual test data will show better placement and orientation
   Eyesore to the community

 How do we plan on demoing this?
 Downloadable android application
  which we will also have on display
 Sensor will real time update our
  phone and calculator
 Users can see the power and
  money that could be saved by the
  ambient light in the room and a
  flashlight
 Increase sensor and transmission
  rate for demo

 New Requirements
   Low Power, maximum of 5v peak operating with
    drawing no more than 2A from our power supply
   Android Application for calculating best performance
    of static solar panel, graphically displaying sensor
    data and a good estimate to dollar value saved by a
    user on a monthly basis
   A hardware device capable of processing and
    transmitting sensor data to the internet
   A sampling and transmission cycle that consumes
    less power than can be recharged via our solar panel
   A sensor array able to accurately sense light intensity
    of the sun in a potential spot for solar panels

 New Design (Pyranometer Array)
   13 sensors
   Silicon Photodetectors
   Temperature sensor for solar efficiency




Electrical & Computer Engineering             8
  New Design Continued.
    Pyranometer array on half sphere
        • Uses many sensors to measure irradiance
        • Irradiance is used to calculate electrical efficiency of
          solar panels
        • Pyranometers act as control points to find an optimal
          direction for solar panel

 New Design Continued.
   Application will have calculator to do most/all of
    the data processing
       • Energy calculations for electrical efficiency from
         irradiance
       • Optimal direction algorithms

 New Components
   Seeeduino Stalker v2.1
       • Real time clock
       • MicroSD card socket
       • Low power ~ 3.3 or 5v IO ports
   Light Sensor Array
       • Silicon Photodetector
   Grove Mega Shield
       • Large amount of digital and analog IO sockets for
         sensor array

 Spending
   Current spending total to date: ~$250
   Money left to date:~$250
   Estimate for production value for unit:~$100-
    $150
   Current market technology: 6-8 design hours,
    digital image processing units (example
    Solmetric Suneye) ~$2000




Electrical & Computer Engineering                   13
 Testing
   This semester:
     • Power supply system meets voltage specs
     • Successfully charge batteries and power board
     • Software functionality tests, updates in database are
       reflected in graphing software
   Next semester:
     • Full system integration testing
     • Flashlight for point light tests, directional awareness of
       device
     • Pspice modeling photovoltaic systems
     • Industry equipment like digital image processing
       camera if we can borrow (would be too expensive to
       purchase)
