• 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

  • Solar Building Design in Arizona

    The idea of using the sun to meet the energy needs in our buildings has been with us since the time of the Greeks, with some of the design manifestations even evident in the prehistoric structures of Arizona and the Southwest. There is a great historic tradition for Arizona buildings that utilize our most abundant resource, and the current increases in The idea of using Read More
  • How Not to- Battery Connections

    Photo shows the situation after a battery discharge test at 300 amps was terminated on a 1530 AH IBE battery string when one post melted. During the discharge test all cell voltages are logged. The sum of the cell voltages was 2.73 volts lower than the 48-volt string voltage. This is an average of 118 mv per inter-cell connection, 5-10 mv is the normal range Read More

What’s Really Green and What’s Really New

Ask Americans what the Green New Deal is all about, and you’ll get two basic answers. Most often you’ll hear, “It’s about moving to renewable energy in order to fight climate change.” You’ll also hear, from a camp further right, “It’s all about socialism!”

Wishing you a wonderful and Happy New Year!

The year 2017 has gone by quickly, and AriSEIA has accomplished a full and active agenda to further solar and renewable energy in Arizona.

Some things to pay attention to in Arizona


Arizona Legislature 

Not in session

Arizona Corporation Commission 

The Arizona Corporation Commission (ACC) has posted STAFF'S THIRD REVISED PROPOSED DRAFT RULES (DOCKET no. RE-00000A-18-0284) That lay out a clearer framework for Electric Utilities to report their compliance with the proposed standards for the Renewable Energy Standard, Clean Peak Standard, Distributed Renewable Storage Requirement, and Electric Vehicle Infrastructure.

See the ACC Staff Report: docket.images.azcc.gov/E000004960.pdf

See also Materials Presented by the Joint Stakeholders at the Commission's March 2020 Energy Rules Workshop

ACC Staff has made substantial changes to the draft rules that were filed on July 2, 2019 based on feedback received at each workshop held in this matter, comments to the docket, and a review of relevant energy policies across the United States.

The Nature Conservancy has submitted their report "Arizona Thrives - A Path to a Healthy and Prosperous Future" to the ACC. Interesting.

APS has submitted their report,  The Solar Center has slightly reformatted this report by rotating the pages for easier viewing.  APS has provided two presentations to address the ACC questions. Worth a read.

Update July 30, 2020: 

When the Arizona utility regulators met to decide these issues they deadlocked over whether they should increase the state's requirements for renewable energy. It proved not possible to obtain the agreement of at least three commissioners, the meeting was adjourned.

See the Arizona Republic article on this:  Arizona utility regulators hit roadblock on clean-energy rules, abruptly end meeting.

The Arizona Corporation Commission (ACC) has released the Notice of Final Rulemaking Interconnection of Distributed Generation FacilitiesInterconnection of Distributed Generation Facilities document.

With this rulemaking, the Commission adds a new Article 26, entitled " Interconnection. of Distributed Generation Facilities" to 14 A.A.C. 2, the Chapter containing the Commission's rules for fixed utilities, with the new Article 26 including 28 new rules. The rules for Interconnection of Distributed Generation Facilities ("DGI Rules") establish mandatory technical standards, processes, and timelines for utilities to use for· interconnection and parallel operation of different types of distributed generation ("DG") facilities; customer and utility rights and responsibilities; provisions for disconnection of DG facilities from the distribution system; specific safety requirements; more flexible standards for electric cooperatives; a reporting requirement; and a requirement for each utility to create, submit for initial approval and submit for approval periodically and when revised, and implement and comply with a Commission-approved Interconnection Manual.

The first dozen pages are basically legal stuff.  The document defines how an utility must review, then accept/reject/etc. an application to connect distributed generation to the utility.  It defines both customer rights and utility procedures.  There are a lot of utility, installer and customer comments along with the ACC staff recomendations. 

 Municipality Info

 

PhoenixFireLogo sm

The City of Phoenix is now (January 2020) requiring a special permit from the Fire Department for most solar systems and batteries.  The fees and required plans varies with size and content.  See this link for an application and details:  https://www.phoenix.gov/firesite/Documents/Solar Photovoltaic OTC Bundle Rev 01-2020.pdf

This is in addition to a building permit from the Planning & Development Department and must be separately obtained at a different address (150 South 12th Street) or on-line via the above link. Also noted is that residential PV permits are no longer over the counter and as of March 2020 are estimated to take 29 working days to process.  Separate inspections are required.

The code requirements are contained in Phoenix-Chapter 12 BESS R-3-1.pdf

Also note: All Phoenix solar building permits are now electronic submittal only. Contact the Electronic Plan Review (EPR) Triage Team at 602-534-5933 or epr.support@phoenix.gov. For more information on EPR, visit us at https://www.phoenix.gov/pdd/onlineservices/electronic-plan-review.

 At the Federal Level

The US House passed the Moving Forward Act, H. R. 2, on July 1, 2020. The US$1.5 trillion infrastructure support bill includes a raft of measures in support of America’s clean economy. The bill proposes to extend the solar Investment Tax Credit (ITC) scheme to 2025. Major resistance is expected in the Senate.

More details on this bill are at: Solar-friendly US infrastructure bill inches forward as it passes House

Update August 4th: 07/20/2020 Senate Received in the Senate.  No action since.  Call your Senators!

 

Utility Information


Arizona Public Service Co. has announced that it plans to produce all of its electricity from carbon-free sources by 2050 and will get 45% of its power from renewable sources like solar and wind by the end of this decade.

This is a good improvement from the point of view of sustainable energy.  There are still a lot of details to be worked out such as the role that distributed energy will take.  Will APS APS improve its policies in regard to residential and small commercial systems.

There are several good news articles and the APS press releases on this announcement:

APS:APS sets course for 100 percent clean energy future

Arizona Republic: APS will eliminate carbon emissions by 2050 and close coal plant ahead of schedule, CEO says

The Washington Post: Arizona’s biggest utility says it will get all of its electricity from carbon-free sources by 2050

 

Tucson Electric Power (TEP) plans to provide more than 70 percent of its power from wind and solar resources as part of a cleaner energy portfolio that will reduce carbon emissions 80 percent by 2035.

TEP has filed its integrated resource plan (IRP) with the Arizona Corporation Commission, outlining plans for 2.5GW of new solar and wind over the next 15 years and 1.4GW of energy storage capacity as it progressively shutters its coal power stations.

See the TEP Press Release for more information: https://www.tep.com/news/tep-plans-clean-energy-expansion-carbon-reduction/

TEP customers intending to install a new PV system now need to check that their system can be safely installed and connected to TEP’s grid.

TEP now has service areas that are saturated with PV systems where new PV systems are subject to additional review and requirements under Arizona’s Distributed Generation Interconnection Rules. TEP has prepared DG Saturation Maps showing these areas.

This further described at https://www.tep.com/get-started-with-solar/

This requirement stems from the recent Distributed Generation Interconnection Rules issued by the Arizona Corporation Commission.
