• 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

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!”

Some things to pay attention to in Arizona


Arizona Legislature 

Senator Gowan has introduced SCR 1048, which proposes an amendment to the Arizona constitution that would require Corporation Commissioners to be appointed by the Governor, rather than being elected by the public. It's important to voice your concerns about this because this regulatory body makes many significant decisions in our state that impact all of us. If passed, this resolution will move to the ballot, where Arizona voters will decide whether or not it is ultimately enacted. We encourage you all to record your position on this resolution. You can do so using the AZ Leg Request to Speak (RTS) tool. Visit their how-to guide to learn more about the RTS System.

Immediate Action Needed: Oppose SCR 1010

A Strike Everything resolution/bill, S.C.R. 1010 was put in motion by Senator Kerr. Per recent reporting by the Arizona Republic, "Proposal would let power customers avoid paying for renewable energy," this measure is a direct attack on renewable energy in Arizona. For more details

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.

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%20Photovoltaic%20OTC%20Bundle%20%20Rev%2001-2020.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.

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

Tesla to close a dozen solar facilities in 9 states

Tesla is closing a dozen solar facilities in 9 states, including some Arizona operations.  

Electric car maker Tesla's move last week to cut 9 percent of its workforce will sharply downsize the residential solar business it bought two years ago in a controversial $2.6 billion deal, according to three internal company documents and seven current and former Tesla solar employees.

The latest cuts to the division that was once SolarCity — a sales and installation company founded by two cousins of Tesla CEO Elon Musk — include closing about a dozen installation facilities, according to internal company documents, and ending a retail partnership with Home Depot that the current and former employees said generated about half of its sales.

About 60 installation facilities remain open, according to an internal company list reviewed by Reuters. An internal company email named 14 facilities slated for closure, but the other list included only 13 of those locations.

Target installs its largest solar rooftop installation in Phoenix

Target installed the retailer’s largest solar rooftop array at its Phoenix distribution center, in a partnership with Chicago-based solar installer SoCore, as part of the firm’s efforts to increase its use of solar power for its energy needs.

The recently completed solar array will generate just under 3,000 megawatt hours of energy each year, providing 30 percent of the center’s yearly energy use.

“We’re excited that our distribution center in Phoenix will feature Target’s largest solar array installation with the iconic bullseye logo for all the sky to see,” said John Leisen, vice president of properties at Target. “Target is committed to enriching the communities we serve, and operating energy-efficient and sustainable buildings is one way we are following through on that pledge in Arizona.”

The new array is one of the 13 solar projects Target completed in Arizona recently, totaling 7 MWh. The retailer plans to install 10 more solar rooftops in Arizona this year. The array is the third largest solar project in the Salt River Project (SRP) territory. It joins other Target solar sites in Tucson (4 stores), Surprise, Peoria, Mesa, Sierra Vista, Glendale (2 stores) and Phoenix (2 sites).

The Arizona solar installations are part of Target’s goal to have 500 stores with rooftop solar panels by 2020, with over 350 installed projects completed already.

Target is increasingly meeting a larger portion of its energy needs with solar power. In fact, Target installed more megawatts of rooftop solar in 2016 than any other U.S. retailer, and in 2016, the company was named the No. 1 U.S. Corporate Solar Installer by Solar Energy Industries Association.

Target has many efforts for it to go green with its energy usage, investing in wind energy partnerships.
