APS Program - summary

Arizona Public Service (APS) offers customers who install
photovoltaic and solar hot water systems the opportunity
to sell the credits associated with the energy generated
to APS.





For grid-tied photovoltaic systems of any size, the credit amount
is $4/Watt-DC up to 50% of installed cost.
For off-grid photovoltaic systems, which must be less than 5 kW,
the credit amount is $2/Watt-DC.
For solar hot water systems, credit amounts are $700 per
installation.
Funds are assigned through a reservation process.
All necessary forms can be downloaded from the
program website. my_community/Solar/solar_35.html
APS - Summary



APS is purchasing solar credits to help the company
meet the state's Environmental Portfolio Standard, which
encourages APS to generate 1.1 percent of its energy
through renewable sources, 60 percent through solar.
Participating customers receive a one-time EPS Energy
Purchase Credit (based on the manufacturer’s rating) for
purchasing and installing systems. APS will have access
to the credits for the life of the EPS program.
APS has recently committed additional EPS funds of
$1,000,000 toward the residential credit purchase
program, and $1,000.000 toward the commercial credit
purchase program for 2005. This brings the overall total
for 2005 to $4,250,000.
APS Program – Qualifications PV






Customers must purchase a new photovoltaic solar
system.
Installations must meet APS interconnection
requirements and customers must sign an
interconnection agreement with APS.
The system must use UL-rated components and meet
IEEE 929 specifications.
A licensed contractor must install the system.
The system generation must be metered separately and
the kWh credits may, at APS' option, be recorded
annually.
The meter (not provided by APS) must be placed
adjacent to the existing meter and marked "solar meter".

The hot water system must replace an electric water heater.
The system owner must sign an agreement assigning rights to the
EPS credits associated with output.
The system must have obtained certification under the Solar Rating
and Certification Corporation’s OG-300 system rating test. Solar
thermal collectors for commercial and large residential systems must
have obtained the Solar Rating and Certification Corporation’s OG100 rating.
Commercial systems must be designed in accordance with ASHRAE
design standards.
The system design and installation must meet all applicable UPC
requirements. The system must meet all state and local building
codes.
The system must be successfully inspected by the building official
having jurisdiction. Proof of inspection must be provided to APS.
The solar panels must be substantially unshaded during peak sun
hours.
The installer must be licensed, bonded and insured.



Incentive Type: A rebate program designed to help reduce the cost
of installing a new solar PV or solar water heating system for homes
and businesses
Photovoltaics
 Rebate of $3/watt, up to 3 kW for residential systems
 Rebate of $3/watt, up to 10 kW for commercial systems


Solar water heating
 SRP offers a payment of $750





Must be UL listed and located in SRP service territory
Must of OG-300 rated and located in SRP service territory
All new solar systems must be installed by a licensed contractor
In exchange for payment, the customer allows SRP to retain the
green energy credits for the system
Payments are set to decrease to $2.70/watt, beginning 1/1/2007
and will continue to decrease at $0.30/watt each year until 2010

TEP information current as of November 18, 2005
TEP – SunShare Options



Option 1 - TEP will provide a rebate of $2,000 per kW of
verified AC output for photovoltaic systems purchased on your
own.
Option 2 - Customers receive a $2,000 discount on a 1-kW AC
output photovoltaic kit purchased from TEP. The kit includes
panels, inverter, supports, meter, and meter socket.
Option 3 - Customers purchase their own photovoltaic
equipment and the rebate amount is based on the installed
solar generating capacity, or DC capacity. With this option
TEP will provide a rebate of up to $2,700 per kW of rated DC
solar generating capacity. To receive the higher rebate, the
system must be operational within 180 days after receipt of the
agreement (systems are reserved for 180 days until the 200 kW
ceiling is reached in each year). The rebate amount will be
$2,700 per kW of DC capacity in 2005 and up to $2,400 per
kW of DC capacity in 2006.
TEP SunShare




SunShare program cap is 200 kW calculated on an AC basis,
which is about 300 kW on a DC basis (this is the APS or SRP
equivalent measure).
SunShare customers assign their environmental credits to TEP
through 2012 for Option 1 and 2 or through 2016 for Option
3. The customer is free to sell their credits on the REC market
after those dates. (This factor in some measure accounts for
the subsidy amount differences between the utilities.)
TEP offers true net metering to all solar and wind systems of
capacity up to 10 kW AC.
There is a system-wide cap of 500 kW AC on this program,
currently subscribed at about 120 kW AC.
TEP – Outside SunShare




Outside the SunShare program, PV systems larger than 10 kW
AC capacity are eligible for a negotiated subsidy payment and
we have 103 kW DC rated capacity of those in our system
now, and have had discussions for at least 2 MW more
capacity.
Those larger systems are not included in the annual 200 kW
AC program cap.
The installations can be residential or commercial.
TEP also offers a community based GreenWatts subsidized
program for community based facilities that can pay the full
cost of material and labor for qualifying installations. Schools,
museums and other non profit organizations benefit from this
program. These installations are also outside the SunShare
program and its annual cap.
