Our Recommendation


3/23

Problem Statement

Design a power grid

Make it usable for many applications Exhibits all of the criteria for success Power cannot be stored for later use

efficiently Designed a power grid that can generatea large amount of power which can alsobe stored.


4/23

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


5/23

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

Very tall and wide nottoo deep

14/23

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


15/23

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.

Solar Map To Completely take over the grid using

Solar Energyo To power a house at lowest levels

Cost equals $200,000o To power a house at mid levels

Cost equals $120,000o To power a house at highest levels

Cost equals $85,000


21/23Wind Map

Turbines need an average of 5.7-6.9m/s wind speeds (12-15mph)

Ocean or coast lines


22/23

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
