Solar electric systems

• Offset electricity usage not gas

• Different from solar hot water/thermal systems

Types of PV Systems

• Stand-alone or Off-grid (Requires batteries)

• Grid-tied (Net metering)

• Grid-tied with battery back-up (Expensive)

Grid-tied

• Homeowner will have black out if utility goes down

• Provides finite amount of electricity per month

• Homeowner continues to get a utility bill

• No batteries, Minimal maintenance

Watt (W) = Basic unit ofPower

• How fastenergy is used/produced

Typical Appliance Nameplate Ratings

• Lightbulb

• Refrigerator

• Air-Conditioner

• Microwave

• TV

• Laptop

Typical module size: 165-230 W

• 60 W incandescent, 15 W CFL

• 475 W, 110 W EnergyStar

• 3,500 W = 3.5 kW

• 1,400 W = 1.4 kW

• 300 W

• 80 W

27. Why Energy Efficiency?

Assume 180 W module produces25 kWh/mo

Traditional refrigerator consumes185 kWh/mo

• Need7.4modules

EnergyStar refrigerator consumes33 kWh/mo

• Need1.3modules

28. Words of the Day: kW vs. kWh

Watt-hour (Wh) = Basic unit ofEnergy

• Amountof energy used/produced

• 1,000Wh = 1 kWh

• • What you pay for! What solar makes!

29. Kill-a-Watt Meter 30. Energy Guide Energy Star 31. Why Solar forLow-Income Families?

Economic

• High energy costs >> Low-income families spend 10% more of their budget on energy bills than the average American

• Unpredictable expenses make budgeting difficult for people on limited income

32. System Costs

Retail Cost of Residential System ($9-10 per Watt)

• Modules (~ $5-6 per Watt)

• Inverter (~ $1 per Watt)

• Balance of System (~ $1 per Watt)

• Installation (~ $1-2 per Watt)

33. Rebates & Incentives

California Solar Initiative (CSI)

• As of 3/2009,$1.55/W(PG&E),$1.90/W(SDG&E),$2.20/W(SCE)

• Current rebate levels -http://www.csi-trigger.com>> Act now, save more

New Solar Homes Partnership (NSHP)

• $2.50/W

• Homes must be at least 15% more energy efficient than current standards

• Beginning 2011, builders required to offer solar as a standard feature in new developments of 50+ homes

Single-Family Affordable Solar Homes (SASH)

• $4.75-$7.00/Wdepending on eligibility

• Fully subsidized 1 kWsystems if homeowner lives in low-income residential housing and meets 50% AMI

• GRID Alternatives is the Program Manager

30% Federal Tax Credit

34. Sample Costs and Savings

Eliminate upfront cost, Cash flow positive month 1

Average reduction in monthly electric bills forlow-income families :80%

Environmental Justice

• One sector of society does not bear the environmental burden for everyone

• Homeowners who can least afford clean energy are often exposed to highest levels of environmental pollution

49. Ladders

Proper angle (4:1 ratio)

3 rungs above roof line

Three points of contact:No carrying things in hands(Use bucket, Hand it up)

One person at a time

Do not step on rungs aboveroof line

Do not place stuff on top ofA-frame ladders

50. Fall Protection 51. Roof

Be nice to the roof

• If you can hear yourself walking on the roof, you are damaging the shingles

• Do not stand or sit on ridge

• Use carpet squares

Dont walk backwards

Be aware of tripping hazards

52. Power Tools

Always wear safety glasses

Use safety on tools when not in use

Replace batteries when they start feeling low

Use the clutch on the drill
