Terminology: Kilowatts (kW) & Kilowatt-hours (kWh) System measured in kW Electricity production measured in kWh Most homeowners install between 2 kW – 12 kW

Part 1 1: S Solar T Technology

What is s net metering? Allows flow of electricity to AND from customer When generation is more than use, extra electricity flows back through meter

– You receive a credit on your power bill for that excess production

slide-16
SLIDE 16

Net metering, co continued Monthly electric bill:

– [Amount electricity used] – [Amount electricity produced]

Utilities required by law to let you net meter

Part 1 1: S Solar T Technology

What happens s when the po power r goes out? When grid is down, solar shuts off (safety mechanism) Need batteries if you want you want power during

Fr Frequently asked questions

  • Warranties?
  • Homeowners’ insurance?
  • Maintenance?
  • How long do systems last?
  • Will HOA allow solar on my home?
  • What if I’m In a historic district?

Solar co co-op

  • p benefits
  • Get best value on

installation and support throughout the process

  • Connect with fellow

solar enthusiasts

  • Become part of the

growing solar movement

Part 3 3: S Solar E Economics

slide-24
SLIDE 24

A few co considerations

  • Solar is priced by the watt (not by panel)

– $9000 / 3000 Watts (i.e. 3kW) = $3/Watt

  • Solar is long-term

– No moving parts & at least 25 year lifespan

  • Average residential electricity rate in WV

– 10-12 year payback time

  • Rising energy prices

– increased value for your solar array

Part 3 3: S Solar E Economics

slide-25
SLIDE 25

Solar is incr creasingly af affor

  • rdab

able

  • Costs have dropped 90%

since the 1970s

  • Solar is no longer a

specialty, expensive, or boutique project

  • But, can still be daunting

to tackle

1970’s Today

Financi cing

  • Loans

– Standard loans – Solar loans & bridge loans – HELOC

  • Grants

– REAP USDA Rural Energy for America Program

  • Solar United Neighbors of WV has a special program to help WV

farms and small businesses go solar anywhere in the state
