Carbon Emission Reduction & Solar Energy for Congregations Chesapeake Interfaith Environmental Group and Chesapeake Bay Foundation Solar Power for Electricity Bob Bruninga, Annapolis Friends Meeting 351 Dubois Ave, Annapolis, MD 21401 http: //www. aprs. org/AFM-environment. html 6 Feb 2014 (rev m) Lighting Electric Vehicle Support
Big Picture! Church Fossil Burning Costs Solar Power for Electricity Electric Lighting Driving Electric Vehicle Support We include EV’s because about half of our easily-fixed spiritual energy is spent driving to church At AFM we currently burn Propane for heat (not shown here)
Tired of hearing: When is the Payback ? ? ? When is the Breakeven ? ? ? Paying for at-home Garbage Pickup is from Day ONE !
Tired of hearing: When is the Payback ? ? ? When is the Breakeven ? ? ? Paying for Sewage Plants – is from Day ONE !
Tired of hearing: When is the Payback ? ? ? When is the Breakeven ? ? ? Paying for Solar Power - is from Day ONE ! Because that’s when we Stop Beating Mother Nature and stealing from our kids future.
Big Picture! 1 House, 1 Year consumes 4 Tons of coal worth of electricity Yes, we have 100 years of coal, but there won’t be anything left of WV!
OUR PRESENT LIFESTYLE IS NOT SUSTAINABLE! Are we part of the problem? Or part of the Solution?
Solar panels eliminate carbon just like trees! SOLAR Panels are equal to trees for Carbon elimination Each Panel = 8 Trees. Our system = 312 trees! = (3 acres of trees)
Buy trees or solar! When is the Breakeven ? ? ? CARBON Carbon Benefit - is from Day ONE ! If you compare based on carbon impact
Lighting: Save 4 to 1 Energy! (breakeven in 5 days!) Cost 50 cents. $2 Save $50 over the life of the bulb! House with 50 bulbs saves $2500 Only 1 in 4 households do it!
35, 000 Solar Power is here. 50% energy savings! 2012
Solar Cost! Equaled Utility in 2010 Half the Utility in 2013 2009 2013
It’s a Whole New World! Grid-Tie • Cost effective in EVERY state since 2009!
Grid-tie Revolutionized Solar • No Batteries! Grid-Tie Every Watt Produced is valued at full Retail Rates!
Angles - less important with Grid-Tie Amazing, even due East, you still get 85% effectiveness!
Angles - less important, More Roof is! Amazing! Increase power by 60% to 100% on other side!
Government Incentives! • Federal gives 30% tax credit. No limit • State of Maryland Grant – – In 2010 for our 8 k. W system was $7000 In 2011 was $5000 In 2013 was $1000 In 2014 is ? ? ? (argh!) • AA County Real Estate Tax credit – $2500 • Total Gov’t Tax Credits return ~ 40% of investment!

(argh!) • AA County Real Estate Tax credit – $2500 • Total Gov’t Tax Credits return ~ 40% of investment! But not for tax-exempt Churches!
Work-Around for Churches! • Workaround = Solar Lease or PPA • Example Lease Program – 0 money down save 15% over 20 years & – 100% down save 50% over 20 years on Today’s rates! & – But rates will probably go up X 2 over same time – So result is paying about 1/4 th for electricity? • Faith Groups are in it for the long term… Just do it…
Grid Solar Power = Emergency Power • COMPLETELY DIVORCE any thoughts of “emergency power” from Economical power. • Solar power (grid-tie) is for ECONOMICAL POWER! • Emergency power has completely different optimal solutions. (Short term and Armageddon) $400 $10, 000 21
Solar Power *is* Economical You have $24, 000 in the bank. Lets say your electric bill is $200/mo. Or $2400/yr or $24, 000 over 10 yrs Keep $24, 000 in a bank at 1%. Continue to pay $200/m for Electricity * After 10 years, you have paid $24, 000 with NOTHING to show for it * And every year you have uncertainty in ever rising prices • And you will keep paying > $24, 000 or more every ten years • And your Savings in the bank has only grown by $2400 Buy a $40, 000 solar system now, ( With incentives, Pay only $24, 000) * Have maintenance free electricity for LIFE * It is generating $2400/year return on investment (10%) for LIFE * You OWN this $40, 000 energy system and all it’s equity for life * After 25 years it is still producing 80% of today’s power! (and will continue) Don’t wait, Solar is the best investment there is! 22
8% - 10% Considering your future of death, taxes and utilities, you can do something about your utilities!
Utility Solar Design Solar to about 90% of need Electric Need The more we invest in renewable energy, The more we become Energy conscious The less we waste The more efficient and sustainable we become! Appliances also are getting more efficient. Generally Solar converts begin to save energy and reduce their remaining Utility Bill to ZERO! Solar
Solar Zero-down LEASE Example Zero Down Lease Usually design for 90% of usage (assume savings and Improving appliances) For $0 down and monthly lease, can beat utility by 15%* & *assuming utility rates rise an average 2. 9% annually
Annapolis Friends Meeting Pre-Pay Example (BGE=14¢) 8¢ SREC’s = $250/m. Whr
Annapolis Friends Meeting 9 k. W Array Completed 31 Jan 2014
Annapolis Friends Meeting 9 k. W Array System Components Inverter Circuit Breaker Sturdy (don’t do this at home!)
Roof Issues: * Is 20 yrs old, plenty of life (but not another 20) * Is shaded
We chose a ground mount system
Annapolis Friends Meeting 9 k. W Array Orientation chosen to maximize Solar & minimize neighbor view
Annapolis Friends Meeting 9 k. W Array Typically, Arrays follow the lay-of-the-land. But with our steep slope, we chose to keep horizontal & adjust edge, but had to pay an extra $1000 for unique engineering
Annapolis Friends Meeting 9 k. W Array Choosing Tilt Angle Tilt angle chosen was 25 deg instead of 35 deg to reduce visibilty ( less than 1% less than ideal) Notice also that orienting to SE or SW would only lose less than 3% from ideal.
50% Energy Spent Driving to Church 50% of Church’s energy/emissions due to driving! With the Solar array, EV driving is 100% renewable Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/EV-charging-everywhere. html
Charge at Home (and at work) Public Charging is like looking for $10 gas! Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/payin-to-plugin. html
Charging While Parked Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/payin-to-plugin. html
Oh the Horror! Our Legacy experience People see this And think $50 Reality with EV’s is 20¢/hr $1 a day Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/payin-to-plugin. html
120 v outlets solve 97% of charging-at-work Church Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/payin-to-plugin. html
Charging Load at 120 v: 1 Coffee Pot = Level 1 EV charging Pay $20/mo For 20 mi commute Bob Bruninga, PE IEEE Transportation Committee http: //aprs. org/payin-to-plugin. html
Plug-in at work (double range, quadruple area) Charge at home only = 16 mi range (chevy Volt) Charge L 1 at work/home = 64 mi range
from 2200 gal/year down to 100 gal/year And we help Environment And save money!
Solar Water Heating – WAS Best Application for solar from 1950 - 2005 Best energy capture per sqft… back in 1950 -2005
Solar PV is now EQUAL to Thermal hot water… Heatpump water heating is a game-changer ! !
Solar PV is actually BETTER than Thermal hot water… ! If 100% hot water not used EVERYDAY… then Excess solar everyday is lost With PV, 100% of solar energy gives full retail value, Independent of how you use it!
So, Lets do the right thing… Move forward with clean Energy Chesapeake Interfaith Environmental Group and Chesapeake Bay Foundation Bob Bruninga, Annapolis Friends Meeting 351 Dubois Ave, Annapolis, MD 21401 http: //www. aprs. org/AFM-environment. html 410 -293 -6417
ELECTRIC Church Fossil Burning Costs Solar Power for Electricity Electric Lighting Driving Electric Vehicle Support We include EV’s because about half of our easily-fixed spiritual energy is spent driving to church At AFM we currently burn Propane for heat
But we should add Heating Energy (Propane) Solar Power for Electricity Electric Vehicle Support Our biggest fossil burning is for Propane heating! Electric Lighting Driving When we convert to a G. S. heatpump we will need to DOUBLE our solar, but we CAN! and we will be carbon free! At AFM we currently burn Propane for heat
Church Heating Costs Propane… Actually our biggest Energy cost is our Propane heating. Switching to Ground Source Heatpump will be our next major Environmental Project
Switching from Propane to Ground Source Heatpump Our heating costs will go down 60% AND being electric, we can replace that with solar for additional savings!
