FOCUSES ON:
•
EDUCATION, RESEARCH, AND
OUTREACH IN RENEWABLE
ENERGY AND TECHNOLOGY
HARDWARE:
• WIND TURBINES, OFF-GRID POWER
SYSTEMS, AND SOLAR CELLS
I wonder…
 How efficient are the solar panels in the SMART lab?
 Are they taking in all of the sun’s energy possible?
A little background
• Reaching Earth: 1400 Watts/m2
• Solar spectrum: Ultraviolet, Visible, and
Infrared
“The amount of solar energy that falls
on the Earth’s surface in 40 minutes =
the total annual energy consumption of
all the world’s people.” –Texas Solar Energy Society
How do we measure effectively?
 Area of material intended to absorb light (m2)
 Ascertain the amount of energy that reaches that
specific surface. (AKA Irradiance)
But…
 Light can be at different intensities at different times
of the day.
the answer is…
Insolation = Power x Time / Area
What is out there?
APRS World: $175.00 + $30
Solar-Log: $277.00
Apogee Instruments: $235.00

Our approach
 We found:
Visible
Rohm Semiconductor: $0.51
Infrared
Osram: $0.82
Ultraviolet
Robotshop: $10.45
Our approach
 3 sensors to implement
 Record and average data at certain
time interval
 Transmit data over Freescale’s
THREAD protocol to server and
upload data to web page
 Budget (for one array):
<$50
Non-technical constraints
Environmental: None
Social: None
Manufacturability:
Opportunities to be
explored
