85% of our energy consumption is from fossil fuels!

component can happen
at any parallel terminal
or even completely
eliminate the output
of a solar array!
**Due to the expense and inherit inefficiencies of batteries it is recommended that they only be used when absolutely necessary (i.e. in remote locations or as battery backup for grid-tied applications if power failures are common/lengthy)
100 amps for 1 hour
1 amp for 100 hours
20 amps for 5 hours
100 Amp-hours =
Rate = C/T
C = Battery’s rated capacity (Amp-hours)
T = The cycle time period (hours)
Maximum recommend charge/discharge rate = C/3 to C/5
# of Cycles
Depth Of Discharge (DOD) %
Year round tilt = latitude
Winter + 15 lat.
Summer – 15 lat.
Max performance is
achieved when panels
are perpendicular to the
Short life ~ 750 hoursIncandescent Lamps
Electricity is conducted through a filament which resists the flow of electricity, heats up, and glows
Efficiency increases as lamp wattage increases
FROM THE POWER PLANT TO YOUR HOME INCANDESCENT BULBS ARE LESS THAN 2% EFFICIENCT
