Inverters Transfer from DC to AC and back
Way to Charge Batteries Controls Volts and Amps
Can be put in Series or Parallel
Why Inverters Get Higher Voltage Less Batteries More Control
Sunny Island Reaches 120 volts Reaches between 41.7 and 180 amps Weighs 86 lbs Optimal temperature is between -13
and 122 degrees (F) 95% efficiency
$4,500
Sunny Boy Charge batteries from solar
panels $2,875 98% efficiency Weighs 77 lbs

Criteria for Success
Safetyo Sturdy enough to keep it up without being too big
Costo Needs to be as cost effective as possible
Coolingo Batteries create their own heat but should be kept at an average of about 77 degrees
Adaptabilityo Base model for a house needs to be able to adapt to different applications easily
Accessibilityo Needs to be easy to access in order to change out depleted/ineffective batteries and/or connections
Sizeo Needs to be a reasonable size in order to install and manage
Weighto Price of installation depends on the necessary machinery to move and manage the weight of each
individual moduleo Weight also determines the placement and platform materials for module.

Design #4
Few terminals for electrocution risk
Module is not heavy, risk of injury from module itself is low
So many cooling vents module itself is unstable
Vents are big enough to get fingers and things in
SafetyPlacement
Adaptability
Accessibility Cooling
Size Weight
Excellent cooling Each battery is
essentially in a wireframe
Very low weight of modulearound 25 pounds
Very low durability of module Batteries weigh 448 pounds Combined weight of about
475 pounds
Front accessibility only Terminal posts are exposed Risk involved with batteries
more so than the moduleitself
Modules easily added Modules can be paralleled
or put in series dependingon the need
In an air conditionedshed
Outside of a house orbuilding
Needs to power airconditioning using
modules
The modules are verybig

Cost Equations Batteries = $2/lb
Steel = $0.35/lb
o Each module uses steel
ROI = (annual savings - (first cost life))
first cost
Cost of solar panels = {[((# of kwh/day take over fromgrid) insolation hours) (30% efficiency)] (1,000)}
($8 $12)
Payback period = First Cost Annual Savings

Explanation of Decision Matrix
To power a house volts need to be 240.o All designs reach required voltage
The higher the amps the better.o Design 1 has the highest amps
Size and Adaptability are similar.o
Smaller the Module better it can adapto Design 1 is the smallest therefore the most adaptable
Weight also ties into size and adaptability.o Design 3 weighs the least and has a good adaptability rating
Able to access but still safe.
o Design 3 is the most accessible but 1 is the safest
Batteries optimally need to be at 77 degrees.o Designs 3 and 4 have the most airflow therefor have the best cooling
Finally cost, high cost is bad the lower the cost the better.
o Design 4 is the cheapest because it uses basically no steel and fewbatteries

Wind Energy
Each Turbine produces 3-4KW/h
Each Turbine costs $2,000 (per KW) Life expectancy of 20-30 years
Problems
o Expensive
o Few places to collect
o Size
o Requires constant maintenance Benefits
o Cheapest cost per KW/h (4 cents)
o
Cheaper then Solar Panelso Constant Ener

Recommendation Design #1
o Safetyo Adaptabilityo Current
o Never low
o ROI
Customers Without Solar Panels and Wind Turbines (inPA)o Only Solar would be a -5.6% Return on Investment (per year)
o Half and half would be a -5.2% ROI (per year)
o Not Worth it
Customers With Solar Panels and/or Wind Turbineso 10.09% Return on Investment (per year)
o Worth it
Investment turns positive when cost for solar panels
and/or wind turbines is less than $20,000.

Recommendation Design #1
o Safety
o Adaptability
o Current
o Never low
o ROI
Best places for windo Unfortunately the best places to put wind turbines are also the worst
They are by the sea and/or in deserts however these places are the most harmful tothe turbines
Best places for solaro In deserts and near the equator
o It cuts the price of the solar panels in more than half
Africa is besto In the Sahara Desert with only solar panels in the first life of the
batteries is -4% ROI
