What’s all the Buzz?

Eliminate Electric Bill Proven Technology

25 Year Warranty, 40+ year life

Huge Environmental Benefits Buy Your Electricity – Stop Renting it

Electricity Terminology

1 watt = enough energy to light a match 1,000 watts = Kilowatt (kW) 1,000 watts for an hour is a kilowatt-hour, kWh Running a 3500-watt air conditioner for an hour is 3.5 kWh. 1,000 kW = 1 Megawatt (MW)

slide-11
SLIDE 11

Energy Use in Context

The average U.S. household used approx. 888

kWh per month. (Dept. of Energy, 2001)

  • Ave. PGE Customer = 750kWh per month.

In CA 1 kWh = 1.5 pounds of CO2 emissions.

slide-12
SLIDE 12

Solar panels convert sunlight into direct current (DC) electricity Power from utility is automatically provided at night and during the day when your demand exceeds your solar production. PV Meter records solar system production. PV Modules are connected into panels

What Makes Solar Work?

  • Net Metering

–Retail Credits for Solar Generation –Account settled annually – True up bill.

  • Accumulate Debits/Credits throughout year
  • TOU Rate Schedule

–Rate based on time of day when energy is used –Sell High / Buy Low

Environmental Benefits

Quiet, benign, no moving parts, no mortality from

  • perations

Pollutants avoided (CO, CO2, NOx, SO2, HC,

PM, etc.) – protecting air, climate.

No water needed to operate (21 gal./kWh is grid

average).

slide-27
SLIDE 27

Environmental Benefits (cont.)

Lessens demand to build and operate Dams,

Natural Gas, Coal and Nuclear power plants.

Reduces need to process and dispose of nuclear

fuel & waste.

Reduces need to drill for natural gas and transport

it to market.

Lowers harmful coal mining operations.

slide-28
SLIDE 28

Solar Benefits

Distributed, reduces peak demand, transmission bottlenecks. Independent from 2001 electricity crisis debt and future price

hikes and supply problems.

Grid-tied systems automatically shut down during a power

  • utage (as required by law).

High quality modules (25 year warranty) - withstand 1” hail.

slide-29
SLIDE 29

Solar Related Benefits

Attractive when installed at roof pitch

(fair comparison are to alternatives).

Shades roof, helps cool house. Helps California achieve RPS 20% RE by 2010 &

80% greenhouse gas reduction goal by 2050!

Important Solar Benefits

Rising electric costs are avoided Solar costs less up front, when financed Investment recouped upon sale of home Savings grow over time Helps to insure human’s long-term success

slide-31
SLIDE 31

Solar Benefits

Yield comparable to high yielding investments. Virtually no maintenance, keep panels clean. No training needed to operate, fully automatic. Creates jobs, saves PV owners money and builds wealth

using local photons .

slide-32
SLIDE 32

When Hiring a PV Contractor

1. Turnkey vs. unbundled services 2. Get recommendations from most recent customers 3. Hire a trained PV contractor; make sure their contractors license is up to date and there are no complaints outstanding

  • n their record.

4. Get estimates in writing 5. Confirm warranty is 10 years on parts and installation 6. Ask about including all permits and rebate paperwork in price

  • f service (e.g. “Turnkey” vs. “a la carte” installation.)

7. For new buildings/remodels – make sure PV installer is connected to other contractors as early possible.

  • NorCal Solar members list www.NorCalSolar.org
  • CalSEIA members list
  • NABCEP certified
  • Diamond Certified www.DiamondCertified.org
slide-34
SLIDE 34

Remember

  • Check the contractors license at the state

contractors licensing board

  • Make sure they have insurance – or you

could be on the hook for accidents

  • Is this someone you can work with, and

you think will be here in 5, 10, 15 years?
