  • - A radical idea to get a high-renewable electric grid

    This is an interesting approach to optaining very high penetration of renewables such as photovoltaics and wind.  At present most large installations operate under Power Purchase Agreements (PPA) wherein the economics are based on a sell all output at predetermined prices. This contrasts with standalone systems wherein the system size Read More

AZ Guidelines-C

Sample Format for Statement of Warranty Coverage
 
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.

C. Statement of Warranty Coverage

To: Solar (type of system) owner at (address)

From: (installation company)

Date: (date of installation)

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.

AZ Guidelines-B

Sample Format for Statement of Performance
 
B. 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 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.

A. 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:
