SACRIFICES TO REDUCE CARBON FOOTPRINT
Don’t Fly—a 737 burns 1 gallon of gas per 1 ½ miles
Don’t Cruise-the Queen Mary burns
2 gallons of bunker fuel per foot traveled
Walk everywhere and save gasoline,
natural gas, coal, diesel, etc.
Don’t eat meat, the flatulence will get you
Don’t use a toilet and save 1 or more gallons of water
Don’t buy on line, UPS or Fed Ex
burns extra fuel to your door
Don’t …
Don’t….
WHY INSTALL SOLAR
PANELS ON YOUR HOME?
?
!1: Solar panels require more energy to manufacture than they
produce in their lifetime.
!2: Solar manufacturing results in more pollution.
!3: Solar is too expensive for widespread usage.
!4: I will store the excess energy I generate in batteries.
!5: When power goes out, my home is still powered by solar
!6: My solar panels won’t work in the cold winter weather.
!7: Solar panels require maintenance.
!8: The payback is far too long.
!9: A solar electric system will raise my property taxes.
!10: Solar panels make my roof to leak, deteriorate, or collapse.

Process: (Due Diligence a must!)
• Establish Specifications-What do you want?
• Research What is Available
• Everything in Writing
• Check With Roofing Company OK to Install Solar Panels
• Solicit and Evaluate Contractors
• Competent Contractors
• Contractor License, Insurance, BBB complaints
• Evaluate Bids,
• Equivalent Design, Conditions, Warranties, Materials
• Price (Turn Key include all taxes, permits, licenses, etc.
• What sets one company apart from others?
• Contract Negotiations and Award Everything in Writing
• Drawings and Specifications
• Review Drawings To Be Sure Meet Contract
• Permit (City, Fire Department, HOA)
• Application to Utility (SCE)
• Installation (3 Days)
• Plan to be there to oversee materials, work being done
• Don’t be afraid to ask questions
• Inspections and Approvals
• City Inspector Your Friend-be with him during inspection
• Connect System –Permission by Edison to Connect
• Notify Insurance Company that panels are installed
• Installer Provides Warranties, Lien Releases, Manual
• Monitor System (Computer App)
• Compare System Production vs. Design
• Generation Daily and Monthly Basis (SCE/App)
• Savings
• Enjoy Meter Going Backwards and $10 SCE Monthly Bill
• File for Rebate With President Obama on your Taxes
• Check For Problems-Discuss with Installer
• Leaks in roof
• Questions you may have
Turnkey Installation including permits and approvals
Contract: $23,000 (special roof connectors, MI,batt. con)
Rebate: $7,000 (will apply w/ 2016 taxes)
Total Capital: $16,000 Net Cost
Anticipated Savings: $1,200 first year
Monthly Electrical Bill: $9.54 for grid distribution (May go up)
25 year guarantee on panels and micro-inverters
10 year guarantee on installation
Current metal roof has 35 year guarantee remaining
Based upon
$100 monthly

!Solar City Lease Contract (free for similar sized system)
!Basic Charge about $80/month
!Tax about $7.50/month
!Surcharge $ 7.50/month
!Total about $95/month
!Annual increase 2.9%
!Very happy with negotiations, contract, installation,
operation and savings
!Alternatives buy vs “free”
!Buying is preferred
!More $ savings
!Risks in possible maintenance costs
!“Free”-apparently problems
!Monthly charge--some complaints little or no savings
!When sell home may be contractual problem
!2.9% increase/year so $75 yr 1 goes to $128 in 20 yrs
!Remove at end of lease, or renew lease
! Problems with my roof:
! Metal shingles need special brackets to assure integrity of roof
! Must know how to walk on roof so won’t dent shingles
! 5 contractors (contract cost before rebate)
! Solar City—no bid due to of roof-some negatives on leasing- free!
! Freedom-$17,000 low bid, not impressed with sales person or co
! Pederson Dean-highly recommended but no bid because of roof
! Infinity solar-$20,000 mid-price, impressed, could not handle roof
! Vasco-$23,000 good company, highest price, could handle roof
!Composite roof which is on most houses
!Remove shingles then built up roof
!10 year warranty on built up roof but 25 warranty on panels
! Rebate
!IRS 30% changes in future years unless congress extends it
!California rebate program discontinued –I did not get it
!Net Metering program with SCE
!I have 20 year agreement with SCE for current pricing
!A future program may not be as lucrative
!Monthly Charge $9.54

1.Do it now! costs for panels low, competition reduces costs
2.Go for the lowest per KWh cost (from reputable company)
3.Contractor should be member of NABCEP
4.Federal Credits 30% thru 2019, 26% thru 2020, 22% thru 2021
5.Lease not as lucrative as buying
6.Warranty based upon output reduction about 0.5% per year
7.Energy generators trying to reduce incentive of Net Metering
8.Be sure roof in good condition
1.Don’t allow roof penetrating brackets
2.Replace roof first if in poor condition

!Making electricity with solar panels, entails 91%
less CO2 pollution than using natural gas, and 96%
less CO2 than coal. Not to mention the sun won’t
run out of fuel for another 5 to 7 billion years.
!Going solar is the simplest and biggest action a
home or organization can take to reduce its
carbon footprint.
!If you believe in global warming/climate change
and don’t have solar panels generating electricity
for your house and car you are a charlatan!
!“Keep it in the Ground” Government policies will
increase KWh costs
!If you can’t afford solar panels-let someone else
do it and at least know you have reduced your
carbon footprint by 20%.
!Do it Now!
!1: Solar panels require more energy to manufacture than they
produce in their lifetime.
!2: Solar manufacturing results in more pollution than is saved
!3: Solar is too expensive for widespread usage.
!4: I will store the excess energy I generate in batteries.
!5: When the power goes out, my home is still powered by solar.
