Government Incentives! • Federal gives 30% tax credit. No limit • State of Maryland 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!

But not for tax-exempt Churches!

Work-Around for Churches! • Workaround = Solar Lease or PPA • Example Lease Program 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” 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 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 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 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 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

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 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.

Solar Water Heating – WAS Best Application for solar from 1950 - 2005 Best 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 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 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!

ELECTRIC Church Fossil Burning Costs Solar Power for Electricity Electric Lighting Driving Electric Vehicle 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 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 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% 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!
