Renewable Energy
The global warming issue is no
longer under debate & with the
rising cost of fossil fuels,
Renewable Energy must become
an option!
Beyond the raw cost of fuel there are the Hidden
Costs from our dependence on Fossil Fuels.
Some of these costs are:
• Health Related Costs
• Macro Economic Costs
• Water and Land Pollution
• National Security
• Thermal Pollution
• Air Pollution

Basic Principal of Solar Power
Solar cells convert sunlight to electricity without any moving
parts, noise, pollution, radiation, or maintenance.
The conversion of sunlight into electricity is made possible
with the special properties of semi conducting materials.
September 16, 2009
How Solar Cells Work
Photons from the sun shine on the solar cell. The photons
actually penetrate into the silicon and randomly strike silicon
atoms. When a photon strikes a silicon atom, it ionizes the
atom, giving all its energy to an outer electron and allowing
the outer electron to
break free of the atom.
The photon disappears
from the universe and all
its energy is now in the
form of direct
electron movement.

Free Electricity From Sun
The DC current is taken from the solar cells and manipulated
into an AC waveform through an inverter.
Inverters sense the voltage and frequency of the AC systems
that they are attached to and begin to “push” current against
that system.
Inverters come in many shapes and sizes for all types of environments.
September 16, 2009
System Integration
A complete system includes:
Solar Panels, Inverters, Mounting
System, Conduit System,
Combiner Boxes, DC Isolation
Disconnects and the Connection to
the Buildings AC Service.
September 16, 2009
Balance of System
Inverters:
Converts DC Current into AC
Current so it can be inter-mixed
with the AC Current coming from
the Electrical Utilities

Net-Metering
Net-Metering
State regulations that permits the sale
of our unused production of Solar
Electricity to the utility for the same
price per KWH as we purchase it.
Over the course of the year we cannot
produce and sell more electricity than
we consume.

Installation Considerations
Orientation
– Does the Array Point Southward?
The more our Array point Southward the more
energy production we will realize
September 16, 2009
Installation Considerations
Angle of Inclination
– The angle that a Solar Module is positioned
above the Horizon.
– What is the Tilt of the Panels in the Array?
The ideal Tilt for our Array is equivalent to our
Latitude Location. The Closer to the Latitude Tilt
we get the more Electricity we will Generate.

Installation Considerations
Shadowing
– A Shadow on our
Solar Panels will
Significantly reduce
the Electricity the
Array will Produce.

NJ’s Clean Energy Program
New Program – Renewable Energy
Incentive Program (REIP) Rebates
– Created by Electric Discount and Energy
Competition Act (EDECA)
– Established Renewable Portfolio Standard
(RPS)
• 20% Renewable Energy by 2020
• 2% Solar Energy by 2020
– $1 Per Watt up to 50,000 Watts
– System size may not exceed 50KW
September 16, 2009
NJ’s Clean Energy Program
Solar Renewable Energy
Certificates (SRECs)
• One Certificate given per MWH of Solar
Electricity Produced
• Certificates Traded on the Open Market
• SRECs ultimately are purchased by the
Power Generators (LSE) to offset their
requirement to produce Clean Energy

 Completion of project application package and forms
 Board resolution using standard draft resolution language template
 LRFP amendment request if required
 Board meeting to pass resolutions to submit project and amend LRFP (if
necessary)
 Submission of completed application to NJDOE timed for project completion (i.e.referendum, summer work, etc.)
 NJDOE issuance of Preliminary Eligible Cost (PEC) letter- project schematic
approval
 Board accepts PEC letter

September 16, 2009
• PV Projects are eligible
for NJDOE Debt Service
Aid but are not eligible for
ROD Grants
• A bond issue for a PV
project may result in no
tax increase• The cost of a roof
replacement project may
be able to be fully or
partially offset by the PV
project revenue stream• Consult with your
financial adviser in
regards to the above.
