• 大发体育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!”

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.

Arizona Legislature 

Immediate Action Needed: Oppose SCR 1010

A Strike Everything resolution/bill, S.C.R. 1010 was put in motion by Senator Kerr. Per , "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 

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 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  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. 

This is a good report that provides a conceptual framework for the Statewide Transportation Electrification Plan for Arizona, including planned or proposed near-term utility actions to support the growth of Electric Vehicles (EVs) in the state。

The report is part of a filing on the Arizona Corporation Commission website: 

 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: 

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 大发体育epr.support@phoenix.gov. For more information on EPR, visit us at .

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:

Battery Storage Costs Drop Dramatically, Making Way to a New Era。 A recent Rocky Mountain Institute (RMI) report continues to confirm that clean electrification through batteries is advancing at impressive rates。 Very interesting report: 

 

 

 

 


Other Announcements

Dr. Bonnie Eberhardt Bobb, Executive Director of the Western Sustainable Agriculture Working Group, is looking for agriculture producers who are using small solar systems in their operations in Arizona who might be willing to help her with preparing ACC testimony, discussion with representatives, writing letters of support, signing petitions, etc. to further their goal of increased renewables in agriculture. She would love to hear from ag producers and listen to their stories of how solar has benefited their operations. Thank you so much. Please contact drbonnie2002@yahoo.com if you can assist.

KOS32072994576 6efac2179b kA team of scientists from across the United States has figured out a way to process wood into a material that’s light and strong, and that has remarkable properties when it comes to reflecting heat. The experiment offers the potential of creating buildings that do such a good job of passive cooling that energy costs will be cut in half. With buildings already consuming 70% of electricity in the United States, and the climate crisis only increasing the demand for air conditioning, the potential impact of a better way to keep buildings cool is tremendous.

In a paper published by , the team writes that the best way to save energy on a building is not to expend it in the first place, and that one way to do that is simply to reflect away heat. That way buildings, especially those in hot and dry areas, don’t have to expend even more energy on air conditioning. And their delignification process for wood seems to create a material that might be widely used, one that holds genuinely remarkable properties.

Wood is composed of a number of materials, with cellulose in lignin at the top of the list. Most of the time, when people are talking about what gives wood its remarkable strength, the credit goes to the complex structure of lignin. But the team making the heat-reflecting wood went the other way. It processed it to break down the usually more resistant lignin, leaving the cellulose behind. Then it compressed the resulting cellulose into a sandwich of layers that create a “reflective, hazy surface” that’s very effective at scattering light.

Many materials have been tested that can radiate away heat at night, but daytime radiative cooling is many times more difficult, as usually materials that can reflect infrared light (heat) absorb visible light and end up turning that light into heat. But the treated wood is very efficient at reflecting infrared light and visible light, with properties that match some heavily engineered metamaterials. But unlike lab-grown metamaterials, the compressed wood may be able to be produced on a scale needed for nationwide construction.

One other result of the treatment is that the material is considerably stronger than the original wood. Its tensile strength (resistance to breaking) was not just 8.7 times that of natural wood, but greater than that of many forms of steel.
