Before installing solar…

Start with Energy Efficiency and Demand Management

• It is more cost effective to make your home more energy efficient before installing solar

• Educate yourself and your customers• Analyze current energy usage• Learn what to do by completing an audit• Explore rate options and other PG&E programs

• Encourage Customers to Take Action to be Efficient– Saves energy and money in 2 ways

• Less usage = smaller energy bills• Reduced load = smaller solar system = lower cost

What is CSI?

The California Solar Initiative provides a financial incentive for the installation of solar on a home or business.

CSI incentives vary by incentive type, customer segment and system size.

Incentive amounts gradually reduce over time.

First funding is reserved, then once installation is complete, the incentive payment is made.

Minimal Shading and Solar AccessObstructions such as trees, chimneys or nearby buildings can cast shadows on PV systems, which can reduce the system’s sun access thereby reducing the amount of electricity the system will generate.

You must indicate on the EPBB Calculator whether there is shading that will have an impact or not.

Option 1: Minimal Shading

Minimal Shading-requires at least a 2:1 distance to height ratio of any object within the orientation of sun to the panels.

If Not Minimal Shading…Option 2: Not Minimal Shading, Enter Solar Access Values

If a system does not satisfy the minimal shading requirement, a shading analysis needs to be performed to generate monthly solar access values.

Solar access can be measured with tools such as the Solar Pathfinder or Solmetric SunEye (available at Pacific Energy Center to loan, visit www.pge.com/myhome/edusafety/workshopstraining/pec/toolbox/tll/)

Measurements should be take at every major corner, but should not be more than 40 feet apart.

Shade Impact Comparison: EPBB vs PBI

PBI•

Incentive based on actual kWh generation

Since entire year’s system availability affects kWh generation, all shade including winter shade affects incentive

EPBB•

Only summer months (May-October) solar access affects incentive

Winter shade has no impact on incentive

What is True Azimuth?True Azimuth

the angle, usually measured in degrees(°), between a reference point (True North Point

0°) and the direction of interest (direction panels are facing)

The magnetic azimuth

is measured using a compass, which does not represent the true north point because of the Earth’s magnetic fields

Therefore, the magnetic azimuth must be corrected by adding (in Western U.S.) the magnetic declination

of a specific location to give true azimuth

Magnetic DeclinationMagnetic North on a

Compass

Page 49: California Solar Initiative Introduction Workshop · The purpose of this workshop is to provide a thorough understanding of the California Solar Initiative and its requirements. We

49

Magnetic Declination Correction•

Look up magnetic declination for specific location at: (http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp)

Enter in zip code, and it will calculate the magnetic declination for that location.

For example:

If you are in San Francisco and your compass shows you a reading of 180°,

you would look up the zip code (e.g. 94105) and add the given correction for magnetic declination of 14°

to get a true azimuth of 194°

On EPBB Calculator, enter the azimuth as 194°

Page 50: California Solar Initiative Introduction Workshop · The purpose of this workshop is to provide a thorough understanding of the California Solar Initiative and its requirements. We

50

Tips for Determining Azimuth

Try to stay 10-15 ft away from metal, motors, rooftop package units or magnets

Store compasses away from cell phones and magnets

Do not place compass directly on module or racking in case there are any magnetic fields present

Check reading against tools like GoogleEarth. There is no azimuth function, but it can be used to provide sanity check for azimuth.

Using the EPBB Calculator: Incentive Amounts

EPBB Incentive

= EPBB Incentive Rate x CSI rating

CSI rating = CEC-AC Rating x Design Factor

PBI Incentive

= PBI Incentive Rate X Actual monthly kWh output*

EPBB calculator will give estimate of the incentive for PBI by calculating estimated annual output (annual kWh) x the incentive rate x 5 years

* As reported monthly by a separate performance meter

Access Issues to ModulesIf issues exist that prohibit access, such as

Weather conditions that may render it unsafe to mount roof

Roof that are too steep or have other structural issues, etc.

The Inspector will require assistance from Applicant by

Providing their shading analysis for EPBB Calculator

Providing an invoice indicating the module manufacturer, model and quantity

The Inspector will still verify if the system output from the inverter is reasonable given the conditions during the inspection

Inspection Results•

Inspector will verify measurements are within the following tolerances:

Tilt +/-

Azimuth +/-

Shading +/-

5%

If inspection results fall within tolerances•

Inspector will accept EPBB calculator as submitted with the Incentive Claim Form and send report to PG&E

PG&E will pay incentive as requested in the Incentive Claim Form

If inspection results fall outside of tolerances•

Inspector will communicate discrepancies to Applicant onsite, if

present during inspection

Inspector will run a new EPBB calculator to get a revised CSI rating and incentive amount

Inspector will send it along with the report to PG&E for further

evaluation

If incentive amount discrepancy is within 5%•

PG&E will pay revised incentive amount based on new EPBB Calculator from inspection

If incentive amount discrepancy is 5% or more•

PG&E will issue a failure

If a failure is issued, the following two options will be communicated to the Applicant and Host Customer and a decision must be made within 30 days:

1. Applicant can accept new recalculated incentive amount2. Applicant can dispute the accuracy of results/measurements

If installed equipment is different (manuf/model or quantity) than that submitted in the ICF/EPBB Calc, new EPBB calculator will be run if it effects CSI rating/incentive

Performance Meter:

is a meter separate from and in addition to the utility’s revenue meter (can be inverter integrated) and records system performance at an accuracy of +/-5%.

Performance Monitoring and Reporting Service (PMRS):

is a service that a customer can purchase to track the performance of their system

through the performance meter or a NGOM.

PBI Only•

Net Generation Output Meter (NGOM):

is a meter separate from and in addition to the utility’s revenue meter and records performance (output) data at accuracy of +/-2%.

Performance Data Provider (PDP): the

entity that collects performance data from the NGOM and provides it to PG&E. This is used for calculating monthly PBI payments and can also be used to provide customer performance data.•

Data for PBI payments is collected once a month

Interconnection OverviewInterconnection is the physical connection of the solar system to the utility grid.

GIS Role

Coordinates interconnection activities, including:

engineering reviews,

metering

access issues

special facilities

execute contracts and administer

Assures that safety protocols are adhered to for the protection of the utility workers and the generator is installed as designed and operating according to Rule 21.

Issues Permission to Operate (PTO).

Provides for two types of solar interconnections (Rule 21): NEM (exporting) and non-

NEM (non-exporting) options for the customer.

Interconnection Application vs. CSI Application

Interconnection Application is a separate, but parallel process to CSI/SGIP Application.

Equipment submitted with the CSI application and the Interconnection Application must match.

Permanent Service must be established (No Temporary).

GIS Field Inspection and Interconnection Agreement must be complete and PTO granted before paid for CSI Incentive.

GIS Application Common Issues

Final building permit (BP) does not match application or is missing.

Single Line Diagram (SLD) has no equipment information: make, model, rating, or…

how many PV modules are connected to each inverter.

Name on application does not match name on PG&E Blue Bill account. (Call:1-877-743-4112 to add name to acct).

Reprogramming fee of $228 for Time of use (TOU) not included. Website has availability and exceptions.

Other Common Issues

System Upgrades: New Application

is necessary showing all generation on site.

Fax coversheet with Reference/Application number is not included

when faxing docs (building permits) to GIS.

Customer/Vendor requesting “courtesy calls”

upon PG&E receipt of final City/County Building Inspection.

Appointments for installation of a PG&E lockbox to gain access not discussed with customer by the vendor.

#1 Issue

Disconnect Access:

Customer’s bi-directional meter must be

installed in a safe, 24/7 PG&E-accessible location, unobstructed by locked gates or pets.

Meter access must be

maintained at all times for reading/system maintenance. Any animals owned by the customer, including pet dogs, should not have access to these areas to avoid hindering PG&E service personnel from completing their work.

PG&E Rule 21(D.1.e) requires PG&E to have a visible, lockable, accessible A/C disconnect device for each generator. It is not required if the customer has a self contained meter that can be utilized as the A/C disconnect for the generator. (98% of PG&E meters are self contained).

Net Energy Metering (NEM)

Electricity can be “exported”

to the grid by the customer.

PG&E can provide any extra electricity or back-up power the customer may need.

Eliminates the need for batteries

Reduces cost and maintenance.

Ensures a constant supply of electricity.X

The utility grid is a two-way street.

Net Energy Metering (NEM)

The intent of the NEM program is that the generation is primarily to offset part or all of the customer’s own electrical requirements.

The electric grid acts as a "battery" for the customer and their meter measures the net usage ("spins backwards" when the customer is exporting electricity to the grid).

In California, systems up to 1 MW can participate in the program; other states typically have a lower size limit.

How NEM Billing Works

Meter runs forwards/backwards and only records “net energy”

PG&E will not pay cash or issue a check for exporting to the grid

Customer receives a monthly charge or credit based on electric rate schedule

Charges/credits carry over each month for 12 months, referred to as “True-Up Period”

Page 124: California Solar Initiative Introduction Workshop · The purpose of this workshop is to provide a thorough understanding of the California Solar Initiative and its requirements. We

124

NEM Billing continued

True-Up Period starts on date of interconnection and ends each anniversary

At end of 12 month period, customer will receive True-Up bill, reconciling all the accumulated charges and credits

Customer will still receive a monthly bill for minimum charge and if applicable, for gas

Customer also receive a separate monthly NEM statement detailing reads and charges/credits to be owed at the end of the True-Up Period

NEM Not for Everyone

Not every customer will benefit from participating in NEM

Reasons:•

Will never export

Demand charges are not eliminated

12 month billing cycle may be difficult for accounting or budgets

Should be evaluated on a case by case basis

Residential Electric Rates

Customers are billed on a tiered pricing structure.

The 1st

Tier represents the essential amount of electricity called “baseline”

Baseline amount is set by legislature and is based on:

Geographic location (Territory)

Season (Winter/Summer)

Permanent Heating Source (Gas/Electric)
