  • New Discovery Could Improve Organic Solar Cell Performance

    While there is a growing market for organic solar cells ­­– they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels – they also tend to be less efficient in converting sunlight to electricity than conventional solar cells. Now, scientists who are members of the Center for Computational Study of Excited-State Phenomena in Energy Materials (C2SEPEM) a new Read More
  • Know Your Rights

    Arizona law protects individual homeowners’ private property rights to solar access by dissolving any local covenant, restriction or condition attached to a property deed that restricts the use of solar energy. This law sustained a legal challenge in 2000. A Maricopa County Superior Court judge ruled in favor of homeowners in a lawsuit filed by their homeowners association seeking to force the homeowners to remove Read More
  • Home Battery Systems

    Rooftop solar panels are common in Arizona thanks to abundant sunshine, but to get even more use from the technology, homeowners are beginning to pair them with large home batteries. Batteries allow homeowners to store their surplus electricity, rather than send it to the grid in exchange for credit from their electric company. Read More
  • Solar Hot Water

    There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't. The typical solar water heater is comprised of solar collectors and a well-insulated storage tank. The solar collector is a network of pipes that gathers the sun's energy, transforms its radiation into heat, and then transfers that heat to either water or a heat-transfer fluid. Read More

SECTION 2. SOLAR THERMAL WATER HEATING

There are two primary concerns regarding solar domestic water heating: component and installation certification (section 2.1), and warranty requirements (section 2.2).

2.1 Component and installation certification (applies to all solar thermal systems):

2.1.1 All installations must meet or exceed the Uniform Plumbing Code (UPS), Uniform building Code (UBC) and the National Electric Code (NEC), at a minimum, and any code(s) adopted by the municipality in which the device is being installed.

2.1.2 As of June 1, 1995, all solar water heating products and systems and their installations must conform to the guidelines and procedures of the current (at time of sale) Solar Rating and Certification Corporation (SRCC) OG-300 document, or equal, with the following exceptions, additions and/or alterations.

 

  1. If the system is installed in any manner other than test conditions, the installing company is responsible for determining and providing for proper collector design flow rate as required to maximize performance and minimize system malfunctions, especially those malfunctions due to water quality conditions. This includes, but is not limited to, pump/pipe sizing calculations and providing a larger pump where necessary to accommodate the system's own specific flow requirements.
  2. If the system is installed in any manner other than test conditions, the installing company is responsible for determining and providing for proper collector design flow rate as required to maximize performance and minimize system malfunctions, especially those malfunctions due to water quality conditions. This includes, but is not limited to, pump/pipe sizing calculations and providing a larger pump where necessary to accommodate the system's own specific flow requirements.
  3. All materials exposed to sunlight, direct or indirect, will be suitable for outdoor use. This includes pipe and pipe insulation (includes coatings), sensor wire, wire connections, etc.
  4. The solar collector must not be shaded during the time period from 9 AM to 3 PM at any time during the year. If future shading is expected, for example, due to vegetation growth, the purchaser must be notified. If avoiding collector shading is not possible, the system purchaser must be given a written statement describing the time periods in which the system can be expected to operate at less than peak performance due to collector shading (see also Section 2.3., below).
  5.  The installation of a suitable electric water heater element control device is required for all electric- assist systems to prevent the electric -assist element from operating during normal solar collections hours. A manual override method must be included and the purchaser must be provided written instructions in the use of override and the resetting of the timer after a power failure if applicable.
  6.  System overheat protection must be included to prevent excessive component temperatures and pressures, and to prevent excessive precipitation of dissolved solids.

 

2.2 Warranty coverage:

2.2.1 The warranty requirements for the "supplier" (as defined in SRCC documents OG-300) will stand as written in the current (at time of sale) applicable SRCC documents. If the system has been certified under a testing authority other than SRCC, the SRCC warranty requirements will prevail.

2.2.2 The warranty requirements for the installation company will be as follows:

 

  1. The installation company will provide a full parts and labor warranty for the entire system for two (2) years from date of installation.

Full parts and labor warranty includes, but is not limited to, any and all component failure(s). whether it is covered by the original manufacturer or not; any and all installation-related malfunction(s); any and all high-temperature problems(s) including those related to water quality. Any manufacturer's warranty(ies) are in addition to, not in lieu of, the installation warranty requirements. Warranty is not required to cover problems resulting from exposure to harmful materials and chemicals, fire, flood, lightning, hurricane, tornado, hailstorm, earthquake, or other acts of God, vandalism, alteration of system by anyone not authorized by the installation company, or any other cause beyond the control of the installation company.

b.  The installation company will provide a full parts and labor warranty against any and all freeze- damaged component(s) for five (5) years. This includes freeze damage due to water quality problems and component failures.

Note b.1: Ambient temperatures below 4 degrees C (39 degrees F) can cause freeze damage to solar collectors, transport pipe and other system components. These cold temperatures and freezing conditions are common throughout the state of Arizona and are not considered an act of God. All freeze damaged system components are subject to the freeze warranty as specified above.

Note b.2: The freeze protection on some system types can be accidentally disabled by the user. Since this condition is intrinsic in the system design, freeze damage due to accidental disabling by the user is not cause for indemnification of the installing company. The installation company is specifically responsible for any freeze damage due to accidental disabling of the freeze protection.

Note b.3: The freeze protection on some system types can be rendered less effective or completely useless due to electric power failures at the system site. Since this condition is intrinsic in the system design, freeze damage due to lack of electric power at the system site is not cause for indemnification of the installing company. The installing company is specifically responsible for any freeze damage due to electric power failure at the system site.

2.3 Written certifications:

For all solar heating systems, the purchaser must be furnished with a written statement of certification (see A), a statement of performance which include what general thermal performance the purchaser can expect from the system under typical conditions (see B), and a statement of warranty coverage (see D). This is in addition to, not in lieu of, all information required to be given to the purchaser by the product and system test certification documents (SRCC OG-300 or equal).

SECTION 3. SOLAR ELECTRIC/PHOTOVOLTAIC (INCLUDING WIND ELECTRICAL ENERGY SYSTEMS)

 

There are three primary concerns regarding solar electric/photovoltaic systems: installer certification (section 3.1), component and installation certification (section 3.2), and warranty requirements (section 3.3).

3.1. Installer certification:

At the time of this document's adoption, there are no installer certification requirements other than those rules and regulations of other State and local entities including, but not limited to, the Registrar of Contractors.

3.2. Component and installation certification:

At the time of this document's adoption (~2008), there are no complete system installation specifically described herein. There are, however, some component and subsystem installation requirements (see 3.2.1).

Those conditions as required by other entities are in effect -- the Registrar of Contractors, for example, requires an electrical contracting license for installation of many solar photovoltaic systems. All installations must meet or exceed the UBC and NEC at a minimum, and any code(s) adopted by the municipality in which the device is being installed.

3.2.1 Subsystem installation and component certification requirements:

There are subsystem installation and component certification requirements for photovoltaic modules and battery systems as required by the specific application. The installer is responsible for ensuring that the subsystem and product installed meets or exceeds all applicable requirements.

 

  1. The photovoltaic (PV) modules and installation must meet or exceed the following testing/safety/performance standards as required by the specific installation (asterisk * denotes required for all modules and installations): All applicable NEC requirements*, U.L. 1703*, JPL Block V,CEC Specification 503, IEC 904-3, IEC 1215. In addition, the PV modules and related components must meet or exceed the following testing/safety/performance standards as required by the specific installation: USHUD approval, RVIA approval. 
  2. The battery storage subsystem must meet or exceed the following testing/safety/performance standards as required by the specific installation: ANSI/IEEE 929-1988 (if utility interface), ANSI/IEEE 937-1987, ANSI/IEEE 1013-1990. 
  3. Wind energy systems generating electricity )as opposed to water pumping, etc.) must conform to the American Wind Energy Association standard AWEA 1.1-1985. 
  4. The solar collector must not be shaded during the time period from 9 AM to 3 PM at any time during the year. If future shading is expected, for example, due to vegetation growth, the purchaser must be notified. If avoiding collector shading is not possible, the system purchaser must be given a written statement describing the time periods in which the system can be expected to operate at less than peak performance due to collector shading (see also Section 3.4., below). 
  5. Any and all connections to the electric utility grid must be made with the permission, approval and cooperation of the utility owning, operating and/or maintaining the distribution system. All components and their installation must be capable of protecting the existing grid and its operators and maintenance personnel from damage and injury per the instruction and approval of the utility responsible for the line access.

3.3 Warranty coverage:

3.3.1 The warranty requirements for the installation company will be as follows:

The installation company will provide a full parts and labor warranty for the entire system for two (2) years from date of installation.

Full parts and labor warranty includes, but is not limited to, any and all component failure(s), whether it is covered by the original manufacturer or not; and any and all installation-related malfunction(s). Any manufacturer's warranty(ies) are in addition to, not in lieu of, the installation warranty requirements. Warranty is not required to cover problems resulting from exposure to harmful materials and chemicals, fire, flood, lightning, hurricane, tornado, hailstorm, earthquake, or other acts of God, vandalism, alteration of system by anyone not authorized by the installation company, or any other cause beyond the control of the installation company.

3.4 Written certifications:

For all solar electric/photovoltaic systems, the purchaser must be furnished a written statement of certification (see A), a statement of performance (see B), which must include what general performance the purchaser can expect from the system under typical conditions, and a statement of warranty (see D).

SECTION 4: SOLAR DAYLIGHTING

There are 4 primary concerns regarding solar daylighting systems: installer certification (section 4.1), installation certification (section 4.2), product certification (section 4.3), and warranty requirements (section 4.4).

4.1 Installer certification:

There is only one (1) requirement for an installer of a solar daylighting device at the time of this document's adoption. The installer must have completed and passed any training provided by the manufacturer of the daylighting device.

4.2. Installation certification:

There are no requirements beyond those conditions specified by the Registrar of Contractors. For those installations not requiring a contractors license, for example, when the total aggregate cost is less than $750, it is recommended that the installing company have a B1 (general contracting) and/or C65R (glazing) license(s).

4.3 Product certification:

There are two requirements for product certification.

4.3.1 The basic device must meet ENERGY STAR® Program Requirements for Residential Skylights.

4.3.2 The basic device must be approved by the Department of Commerce Energy Office as a solar daylighting device. The manufacturer or the installing company must submit to the Department of Commerce Energy Office (1700 W. Washington Street, Suite 220, Phoenix, Arizona 85007) a detailed description with accompanying graphics (drawings, photos) for each model with substantial design differences. It is not necessary to obtain ENERGY STAR® Program Requirements for Residential Skylights or DOCEO approval of additional models within a model range or for minor design modifications that are supported by an engineer's written report that the additional model meets or exceeds the performance of the approved model(s). The Energy Office will issue a written response regarding the status of the device.

  1. The purchaser must be supplied a copy of the letter stating that the device is a qualified device at time of installation completion.

4.4 Warranty requirements:

The installation company will provide a full parts and labor warranty for the entire system for two (2) years from date of installation.

Full parts and labor warranty includes, but is not limited to, and and all component failure(s), whether it is covered by the original manufacturer or not; and any and all installation-related malfunction(s). Any manufacturer's warranty(ies) are in addition to, not in lieu of, the installation warranty requirements. Warranty is not required to cover problems resulting from exposure to harmful materials and chemicals, fire, flood, lightning, hurricane, tornado, hailstorm, earthquake, or other acts of God, vandalism, alteration of system by anyone not authorized by the installation company, or any other cause beyond the control of the installation company.

4.5 Written certifications:

For all solar daylighting systems, the purchaser must be furnished with a written statement of certification (see A); a statement of performance (see B), which must include what general performance the purchaser can expect from the system under typical conditions; and a statement of warranty (see D).

  1. Sample format for Statement of Certification -- all systems: To be signed by installer and supplied to purchaser upon completion of installation. Sample only: subject to change without notice.

 

Statement of Certification

 

To: Solar (type of system) owner at (address) From: (installation company)

Date: (date of installation)

RE: Solar (type of system) certification requirements

Your solar (type of system) has been custom designed and installed for your needs.

The system, individual components and installation meets or exceeds all the current State of Arizona solar (type of system) requirements.

The installation has been supervised on-site by a certified solar technician who has met all the requirements of the State of Arizona at the time of installation (if applicable).

The system warranty meets or exceeds all of the requirements of the State of Arizona at the time of installation. A copy of the State of Arizona solar system warranty requirements is attached.

The performance of the system is approximated and stated on the attached Statement of Performance.

The system meets or exceeds all the State of Arizona requirements for the solar sales tax exemption and solar tax credit legislation.

I hereby declare that I am an authorized representative of (installation company) and further declare that all of the above statements and the statements on the attached documents are true and correct:

 

(print name) (signature and date) (company name)

 

  1. Sample format for Statement of Performance -- all system types: To be signed by purchaser and seller at time of sale and supplied to purchaser as part of Statement of Certification package. Sample only

-- subject to change without notice.

Statement of General Performance

To: Solar (type of system) owner at (address) From: (selling company)

Date: (date of sale)

RE: Solar (type of system) certification requirements

Your solar (type of system) has been custom designed and installed for you needs.

There are many variables affecting the performance of your solar (type of system) including, but not limited to, general weather patterns, specific site conditions, energy use patterns and other conditions not subject to the control of the system designer(s) and/or installer(s).

However, without stating or implying a guarantee of performance, this system is expected to provide approximately (xx)% to (yy)% of the total annual (water heating, swimming pool heating, spa heating, electric lighting/appliance. lighting, space heating/cooling, etc.) energy requirements of your application under typical conditions.

(Add a paragraph to describe more specifically what the purchaser can or cannot expect. For example, for pools, it will be necessary to state that the pool temperature generally will not be adequate for comfortable swimming all year, especially from say, November to March, or whatever the system was not sized for. Another example will be if collector shading will adversely affect system performance during any part of

the year. If the system cannot be installed reasonably close to the test parameters -- tilt, orientation, etc. -- the purchaser must be informed. For example, if the collector is to be installed as a flush roof mount resulting in significantly less-than-tested tilt, or if the system, must be oriented east/west, the purchaser must be informed here. For PV systems, a brief explanation of peak watts is useful so the purchaser understands that the module will supply peak watts only under ideal conditions.)

Seller: I hereby declare that I am an authorized representative of (selling company) and further declare that all of the above statements are true and correct:

(Print name) (signature, date) (company name)

Purchaser: I have read and understand the contents of this Statement of Performance. I further understand that this statement provides a general understanding of what I can expect from the solar system and I understand this is not a guarantee, implied or otherwise, of performance.

C: Sample format for Statement of Warranty Coverage -solar thermal: To be supplied to purchaser as part of Statement of Certification package. Sample only: subject to change without notice.

Statement of Warranty Coverage

To: Solar (type of system) owner at (address) From: (installation company)

RE: Solar (type of system) certification requirements

The warranty requirements for the "supplier" will stand as written as defined in the current (at time of sale) system test/certification documents (SRCC OG-300, OG-400, or equal).

The warranty requirements for the installation company will be as follows (this warranty supersedes all other warranties for the time periods stated):

a). The installation company will provide a full parts and labor warranty for the entire system for two (2) years from date of installation.

Full parts and labor warranty includes, but is not limited to, any and all component failure(s), whether it is covered by the original manufacturer or not' any and all installation-related malfunction(s); any and all high-temperature problem(s) including those related to water quality. Any manufacturer's warranty(ies) are in addition to, not in lieu of, the installation warranty. Warranty is not required to cover problems resulting from exposure to harmful materials and chemicals, fire, flood, lightning, hurricane, tornado, hailstorm, earthquake, or other acts of God, vandalism, alteration of system by anyone not authorized by the installation company, or any other cause beyond the control of the installation company.

b.) The installation company will provide a full parts and labor warranty against any and all freeze- damaged component(s) for five (5) years. This includes freeze damage due to water quality problems and component failures.

Note 1: Ambient temperatures below 4 degrees C (39 degrees F) can cause freeze damage to solar collectors, transport pipe and other system components. These cold temperatures and freezing conditions are common throughout the state of Arizona and are not considered and act of God. All freeze damaged system components are subject to the freeze warranty as specified above.

Note 2: The freeze protection on some system types can be accidentally disabled by the user. Since this condition is intrinsic in the system design, and therefore can be predicted, freeze damage due to accidental disabling by the user is not cause for indemnification of the installing company. The installation company is specifically responsible for any freeze damage due to accidental disabling of the freeze protection.

Note 3: The freeze protection on some system types can be rendered less effective or completely useless due to electric power failures at the system site. Since this condition is intrinsic in the system design, freeze damage due to lack of electric power at the system site is not cause for indemnification of the installing company. The installing company is specifically responsible for any damage due to electric power failure at the system site.

Financing Renewable Energy Systems

Financing Renewable Energy Systems

Financing has become a major factor in the adoption of renewable energy systems in Arizona.  Approximately 80% of the residential photovoltaic systems installed in 2016 have been financed by one means or another.  Many of the large commercial and utility scale photovoltaic systems have been developed and installed using Power Purchase Agreements (PPA) where in one party owns the photovoltaic system while another party purchases the energy.

The following links will help in understanding financing of renewable energy systems in Arizona:
