California has been supporting Solar Industry for many years by approving aggressive goals towards lowering our state dependency on fossil fuel. Following are some of California's goals for spreading the use of renewable energies such as solar: 

 

California 2020-Solar Mandate:

 1200px-Flag_of_California.svg

A plan was passed in 2020 (by California regulators) that will mandate new homes and major remodels up to 3 units in the state use solar energy. This important victory for homeowners will become effective in 2020.

California has always been the leading state in High Technologies and Clean Technologies, and that is why California managed to be world’s 5th largest economy. This approval makes California to be the first state in the nation to mandate solar power system installation on single-family residences as well as multi-family residential properties (up to 3 stories) including condos and apartment complexes.

This move will be very much beneficial for everyone, because it will create a lot of jobs for manufacturers, designers, installers, advisors, etc. Moreover, it will help our economy because it will lower our dependency on fossil fuel to generate electricity. Not to mention that this move will help Californians to benefit from a cleaner and greener state.

The approval of mandatory solar panels for new construction is expected to add on average about $9.500 to the cost of new houses which will be offset by the reduction or elimination of the electric bill.

Most of the industry experts including Abigail Ross Hopper, president and CEO of SEIA (the Solar Energy Industries Association) believe this is a historic decision for the state and the U.S.

All contractors develop relationship with financing companies, but not all financing options are equal. Hence, it is always better to work with the right solar installer who carries your best interest and the right solar financing/loans.
  3. Apply for incentives: Your EAH Energy Advisor will explain your incentives for you, but timing is key, and it’s important to keep in mind the LADWP incentives are expiring soon.
  4. Complete Permitting Process: This must be done by your solar installer and it is extremely important for them to be fully familiar with the process, otherwise it will turn out to be a lengthy process.
  5. Once the permit is issued, your installer will install your solar power system, and afterwards it will be time for interconnecting your solar system to the utility grid.
  6. Finally, you should submit your incentive claims to be processed.

Permit process:

Permits

The City of Los Angeles requires a building permit for the structural support of all solar energy device installations with the exception of the following list below. Their requirements, regulations and codes may change from time to time, so it is highly recommended to work with an experienced and licensed solar installer or by visiting LADBS for more up to date information.

A building permit is not required when all of the following requirements are met:

  1. Solar device is roof mounted and does not exceed the existing building height at the highest point,
  2. The solar energy device system weight does not exceed four pounds per square foot,
  3. The solar energy device is installed within 18” of the roof immediately below,
  4. The maximum concentrated load imposed by a solar energy device support onto the roof structure is a maximum of 60 pounds (0.18 kN); and
  5. For wood construction, the maximum spacing for supports of the solar energy devices are be 48” on center, and are anchored to solid roof rafters or to solid blocking with a minimum of one 5/16” diameter lag screw embedded a minimum of 21/2”, or as recommended by the manufacturer, (whichever is more stringent). For other type of construction, the support shall be approved by the Department.

Building Plan Check

Structural support of solar energy devices requiring a building permit are to be submitted to a building plan check for approval. You may apply for Express permit if your permit does not require a plan check.

A plan check with LADBS is required if your solar installation project is more complex and does not meet the requirements for an Express Permit.

Complete plans are to be submitted showing dimensions and location of the supporting structure in relation to the property lines and any adjacent building.

  • Substantiating design calculations are required for supporting member sizes, connection details, and design loads imposed on the roof or other support.
  • Where the solar panel/collector surface inhibits superimposed concentrated loads, the weight of the collector may replace part of the code-required live load.
  • Regardless of the weight of the solar panel or collector, a minimum of one-half of code required live load should be used for design.
  • The wind load on the vertical projection of the collector is to be included in the analysis.
  • Provide a note on the plan, “No guardrails are required for installed solar energy devices pursuant to LAMC 91.1013.5.”
  • All roof penetrations are to be sealed using approved methods and products to prevent water leakage.

Electrical Plan Check/Electrical Permit

  • Electrical Plan Check: Electrical plan check is required for all photovoltaic system installations.
  • Permits: An electrical permit is required for installation of solar photovoltaic systems.

Express Permits Exception: Plan check is not required if all of the conditions listed below are met:

  1. The installation is in a one or two family dwelling.
  2. A maximum of 2 strings are installed per inverter.
  3. The total capacity of the photovoltaic system being installed is 10 KW or less.
  4. No DC combiner box is installed (other than the box that is part of and is listed with the inverter).
  5. System contains only inverters with isolation transformers.
  6. No GFCI or AFCI overcurrent devices are installed in the Alternate Current (AC) output of the inverter.
  7. Modules shall be roof mounted crystalline or multi-crystalline material.
  8. AC Power system shall be 120/240 volts single phase.
  9. The minimum service panel size should meet one of the following:
    1. 100 amps for systems with a maximum 20 amperes dedicated AC branch circuit, or
    2. 150 amps for systems having a maximum 30 (or two 15) amperes dedicated AC branch circuit(s), or
    3. 200 amps for systems having a maximum 40 (or two 20) amperes dedicated AC branch circuit(s).
  10. The rating of service panel shall not exceed 225 amperes.
  11. No AC modules, storage batteries, hybrid systems, or microinverters are installed.

If the above conditions are met, you can submit Form E and Form EPv to the express permit counter.

Permit for Photovoltaic Systems which do not require an Electrical Plan Check (Express Permits):

  • Prior to permit issuance, the Express Permit Counter staff is to refer all permit applications for photovoltaic systems to the Los Angeles Fire Department (LAFD) for approval. In addition, the Express Permit Counter staff will initialize the permit application for photovoltaic system(s), create a clearance summary sheet for Zoning Approval, and direct customers to the Zoning counter to obtain clearance approval.

Fire Department and Zoning approval

fire_station.1200x627

LAFD approval is required for all solar photovoltaic systems (solar power systems) permits. LAFD’s installation guidelines are available at LAFD Website.

All Express Permits and electrical plan checks must have an approval from the Zoning Counter for a clearance.

  • It must be determined by the zoning staffs if the site is within a Specific Plan, HPOZ, ICO, CRA, or if it involves a historical monument (i.e. CEQA review) and must refer customers to the appropriate agency by creating the required clearances, if clearance approval is required.
  • Once all the clearances are approved by the appropriate agency, the Zoning Plan Check Counter staff shall approve the zoning clearance in PCIS and direct customers to the Express Permit Counter (for Express permits) or to the Electrical Plan Check counter (for electrical plan check applications) to complete the process.

Construction of your solar power system and City Inspections:

Once all of the mentioned permits and clearances are issued, then your selected solar installer can install the solar panels for your house. Upon completion of your installation, LADBS and LADF inspections start. You or your solar contractor must contact building and safety for inspection.

LADWP solar inspection

Once your incentive payment claim is submitted, a solar inspection will be initiated upon completion of all the required documents and steps. The inspector schedules an appointment to visit the job site to verify the system specification and installation details. Once it is confirmed by the inspector that everything has been done by code and in compliance by the approved plans, then the inspector will install net meter and remove lock, but the system cannot be turned on until the final approval of the solar installation is submitted to the solar group by the inspector.

4. Solar Installation Permit in City of Pasadena CA

CITY-HALL

According to Pasadena Water and Power website, as of 01/01/2018, PWP will no longer offer any incentives for solar installations. Although incentives are no longer offered, installation of a solar power system is still beneficial and PWP staff will continue to assist customers who are interested in installing solar photovoltaic systems in their home or business.

Currently, PWP electric customers who have a solar PV system and a solar meter (provided by PWP) are eligible to receive compensation for any “net surplus electricity generated by their system.

You should consider the following items before starting the process:

  1. Eligibility: If you are an Electric Customer of PWP, you are eligible for the PSI program.
  1. A PSI application approval must be obtained from PWP before applying for a building permit for a solar installation. A separate application is required for each PWP electric account/service/meter.
  2. All PV systems must meet the technical requirements listed in Public Resource Code Section 25782 and described in the next section below, “Technical Requirements.”

The following are some of the technical requirements according to PWP website:

  1. Solar System Size, Location, and Ownership Requirements
  • System Size: The solar energy system must be between 1kW and 1,000 kW CEC-AC and intended primarily to offset part or all of the customer’s own electricity demand. Systems should be sized to produce no more than 100% of the customer’s average annual energy consumption as shown on the PWP billing record for the three years previous to the application submittal. If the customer’s account has less than a three year history, the average will be calculated with available data.
  • New or Expanded Facility: Applications with new or expanded sites with no electric bill history or where the existing electric bill does not reflect the customer’s expected expanded consumption, must include an estimate of the expected expanded consumption. Suggested methods of demonstrating load growth include building simulation program reports such as eQUEST, EnergyPro, and DOE-2; Title 24 energy modeling report (including ECON-1 sheet). The PSI Program Manager will request copies of building permits for the new construction or expansion.
  • Added PV Capacity: Solar systems installed under previous Solar Program qualify for additional solar capacity under PSI. New application is required and current PSI requirements will apply.
  • Location: The PV system must be permanently installed on the same premises where the customer’s electricity demand is located.
  • Interconnection: The PV system must be connected to PWP’s electrical distribution grid.
  • Ownership: The customer may lease the PV system or purchase its output from a third-party PV system owner/operator/installer.
  1. Interconnection to the Electric Utility Distribution System

Eligible solar electric generating energy systems must be permanently interconnected to the electrical distribution grid of the utility serving the customer’s electrical load. Portable systems are not eligible. The system interconnection must comply with applicable electrical codes and utility interconnection requirements.

  1. Solar Energy System Components and Warranty

All components in the solar energy system must be new and unused and must not have been previously been placed in service in any other location or for any other application.

All major solar energy system components, including PV modules, inverters, and meters must be included on the CEC’s Eligible Equipment Lists.

All solar energy systems must have a minimum 10-year warranty provided in combination by the manufacturer and installer to protect the purchaser against defective workmanship, system or component breakdown, or degradation in electrical output of more than fifteen percent from their originally rated electrical output during the ten-year period.

The Utility AC Manual Disconnect Switch shall be readily accessible to the Utility at all times and located immediately adjacent to the Customer Service Equipment that functions as the Point of Connection to the electric utility.

The purpose of the Utility AC Manual Disconnect Switch is to provide a separation point between the solar system and the Utility Electric Distribution System. The Utility AC Manual Disconnect Switch is to be used to isolate the PV system ONLY during operational conditions in order to safeguard utility personnel.

The Utility AC Manual Disconnect Switch should be installed upstream to the solar system and it must be able to electrically disconnect the entire solar system, including the performance meter. AC Manual Disconnect Switch must be permanently marked to identify it as a Utility AC Manual Disconnect Switch.

If the location of the AC Manual Disconnect Switch cannot be installed within eight (8) feet from the Point of Connection to the electric utility, its location must be approved at the discretion of the Utility. All questions regarding the location of the Utility AC Manual Disconnect will be directed to the Utility Service Planning Department at 626.744.4495.

  1. Meter Requirements

The PSI Program requires accurate energy production meters for all installations. Accurate measurement of solar energy output is of paramount importance to ensure optimum value for solar owners.

PWP requires a performance meter (Utility Grade Single Socket (SS) 4 clip) in all solar installations. Performance meter must be supplied and installed by the solar contractor/installer.

Meters and service panels must meet all local building and utility codes.

PWP will replace the existing utility meter with a solar net meter after the system passes PWP Field Inspection and before the system is authorized to connect to the grid at no cost to the customer.

  1. Maximizing Solar Generation

All solar installations are required to submit shading analysis reports generated by a shading analysis tool such as the Solar Pathfinder or the SolmetricEye

For all solar systems, the applicant is required to input monthly shade impact results from a shading study conducted at the proposed system site. These inputs are used as monthly derate factors (100% = no shading, 0% = total shading) to adjust the PV Watts output for shading. The shade analysis tool must be specific to the location, azimuth and tilt of the system being measured and must correct for magnetic declination.

For rectangular areas, a minimum of four (4) shading measurements must be taken, one at each corner. For irregular areas, a shading measurement is taken at each corner.

PWP performs a final inspection and commissioning for all solar installations in order to verify that the project is installed as represented in the application and conforms to the eligibility criteria of the PSI Program.

  1. Energy Efficiency Audits

An Energy Efficiency Audit is required prior to installing your solar power system.
