Possible Solutions
Solar Wall and Duct
Solar Hotbox
Heating Strip
Solar Heating
3 unfinished projects

Good Solar Site
South facing
No obstructions
Appropriate angle for winter
Needs a finished product
Prevent Super Cooling Golf Carts

Challenge
Short time frame to finish
Outside air temperature
30°F-40°F
Large volume of stagnant air
Change in heating goals
Previous projects
Minimal Maintenance
Fan
Temperature Switches


Other Projects
Observe the Hot Box in Winter
Refurbishing old Hot Boxes
Provide Power
Put in Gutter Down Spouts
Add PVC to act as a Radiator
Very expensive
Requires additional changes to the storage building
Patented by Conserval Engineering
Uses little energy
Physically appealing
Durable
Use the heat strip to heat the air and prevent freezing


Heat strips meant for conduction not convection
Takes large amount of power
$0.33 per hour
Require multiple heat strips
Very Inexpensive
Durable
Use little energy
Recycled materials
Physically appealing
Define Success
Construction and Installation
Qualifiers

Keep building above freezing throughout Winter
Improve charge retention of batteries
Increase lifetime of batteries

Measurements
Measure temperature at 1ft - 10ft
4ft. x 8 ft. box
Industrial heat fan
Temperature switch
Damper
Around 300 recycled cans


Roof insurance
75ft from nearest possible solar site
Problem occurs late in the afternoon or at night
Site is close to the roof edge
No chance of solving the problem
