Transcript of Photovoltaic and Small Wind Projects for your Classroom
SUNY College of Technology
Jeffrey Stevens, Associate Professor
Electrical Trades Department Renewable Energy Training
Renewable Energy Projects
for your Classroom
Integrate the projects into the
classroom (curriculum)
Lessons learned:
At first… I thought full systems were better ...not true!
1. Student’s ability to manage & operate
2. The more expensive & complex the…
3. Less set-up and tear-down…
4. Multiuse…recruitment and demonstrations
Two methods/techniques
1. Purchase –
out of catalog or off the shelf
2. Build/Design –
from your classroom/supply closet
Two methods/techniques
1. Purchase –
out of catalog or off the shelf
Pros: cleaner, complete, ready to go
Cons: is the process understood, repairs/parts,
half the fun…
1. Purchase – out of catalog or off the shelf2. Build/Design
Pros: you understand the process,
integration / it’s about inclusion,
know the repair, student involvement,
always room to improve/modify
Cons: maintain safety, less flair/pizazz,
you need to enjoy, as the teacher, before they will…
The repertoire…
Kill a Watt meter Watts up Pro(approx. $30) (approx. $140)
Both measure energy (volts, amps, watts, Kw)
Kill a Watt is portable and measures PF
Watts up is recordable and a computer interface
Provide visual of energy usage/cost
The “extra fridge” in my house $$$Cost me
The repertoire… P.S. - Let’s take this to the classroom.
In Wellsville, NY, I pay – 3.5 cents ($.03) per kWh
consumed.
At $20.04 per month, how many kWh is that?
OR
How about at your home? Most electric customers pay
12 – 17 cents ($.12-$.17) per kw. That is how much per
month for your grandmother’s old fridge?
The Vandegraph Generator:
(Van de Graaff ) $100- $400
-The best attention-getter
-Standard 120V or
GO GREEN
-Invert 12V – 120V (renewable) battery powered
-Demonstrate basic energy principles
The repertoire…
WinDynamo II Wind Generator (approx. $300) (www.pitsco.com)
-Activity board for converting energy –light/sound/mechanical
-Adjustable blades – manipulate wind
-Recordable set points for analysis
-Low to high wind use
-Standard fan
-Variable loads
The repertoire…
Handheld Anemometer –($65-$110)
www.inspeedstore.com
Portable
Wind games
MPH/KPH
Puts a tangible factor into wind
power
The repertoire…
PV panels – 5 Watt, 10 Watt ($65–$85)
www.dcpowersystems.com
(Contact me for my distributers)
Multi crystalline silicon photovoltaic module
Just like the big boys’/girls’
Portable/gangable (array build)
Powers small loads (lights, pump)
The repertoire…
The system offers three small 15-watt
panels which can be grouped together
to train on array sizing and basic
electrical theories.
The output devices can be altered with
a digital meter reading, aiding in
showing load and production variances.
Cost: $160-$250
The repertoire… PV tabletop demo www.harborfreight.com
Attic vent fan
The repertoire… A small 400W turbine on a
adjustable pole for training
and demonstration.
Turbine – $800
Tower – $300
• Allows “field” tests
• 12V battery charge
• “Mobile”
• Real
Envi Current Cost Meter (approx. $150) Whole house measurement, as well as, individual appliances Measures and records energy, with cost analysis (volts, amps,
watts, Kw) Connect into main panel board or circuits Recordable and computer interfaced Provides visual of energy usage/cost
The repertoire…
This Davis Weather
System has offered a
surprising level of interest.
Weather patterns
Solar insolation/ UV
Wind speed/max
Rain/barometer
Tons of data & #s
System :
$300-$800
+ 42” Monitor Display
Helps make the theories and numbers REAL!
The repertoire…
Fuel Cell Car (PV)–
(approx. $125)
www.sciencefirst.com
www.pitsco.com
Powered by battery or PV
Ability to combine technology
Hybrid training – multiple trades
Numerous experiments
The repertoire… “ Build it and they will come”
Give them the vision and the opportunity……
and
they will come RUNNING !
The repertoire… “ Build it and they will come”
Give them the vision and the opportunity……
and
they will come RUNNING !
The students, that is…back for more!
Using the students, we have modified and added to the collection.
Combining projects and components.
Two methods/techniques
1. Purchase –
out of catalog or off the shelf
2. Build/Design –
from your classroom/supply closet
Energy Light Box
This is by far one of the most popular
Compare energy usage of standard and CF bulbs
Use along with a Kill a Watt meter
Parts: Keyless light fixtures, wire, box, receptacle boxes, bulbs (incandescent and CF)
Folks love this – ratio is visual (4:1)
Light output is the same
Low Voltage
CF (Compact Fluorescent)/LED
Battery Build
•Measurable amperages and voltage to compare use
•Power with PV modules or batteries
•Multiple applications for labs
• Visual aspect: renewables & alternate sources
Pump PV Demonstration - $150+
Using the 10Watt PV panels
( add more modules to build an array)
Water (fans work, too)
SEE the orientation to the sun
(Azimuth and Altitude)
12V RV pump moves energy from the sun
working (or not)
Great for watching the effects of shading
Battery Bank / Supplies
($10; leads: $5/dozen)
Learn basic energy series and parallel circuits
(See PV design and install manual – SEI)
We use the battery to teach PV array
configurations without the extensive wiring
Safe but real (fuse protection)
PLC Music Box
($130 base)
Demonstrate advanced concepts in
practical/fun ways.
Building blocks
Basic to advanced logic controller
programming
Capstone class/student project

Don’t Forget the Web:
Have Patience…. It takes time.
Starts as a nice ‘wow’ toy, grows to…
Student focused – Student-to-Student
Utilized in public awareness and recruitment

Don’t Forget the Web:
Remember: alfredstate.edu
You’re here...this is for your use
Remember…
for us, it’s a new way of thinking and teaching, and LIVING.
For our students it’s just
the way to LIVE!
To them,
renewable is NATURAL!
