• 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

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


Seeking Arizona agriculture producers who are using small solar systems in their operations in Arizona

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.

SRP approves rate decrease as directors argue about solar power and batteries.

During March 2019, SRP wrapped up their public pricing process at a final rate setting board hearing.
The board approved new rates for SRP customers, which will translate to a $1 to $4 decrease in monthly bills.
The board also voted to lower rates for solar customers, approve three new options for solar customers, and adopt a new battery/storage incentive.

FRAUD ALERT

Attorney General Warns About Deceptive “Solar Initiative” Flyers

PHOENIX – Attorney General Mark Brnovich issued a warning today about deceptive flyers appearing on residences in the Phoenix area that promote a solar energy effort.

The flyers claim to be a “Public Notice” from the “Maricopa County Solar Initiative,” and claim that “Arizona and the Federal Government ITC (26 USC § 25D) are paying to have solar energy systems installed on qualified homes in this neighborhood.” The flyers tell consumers to call to schedule their “site audits.” Consumers who call are subjected to a solar sales pitch by a private company. In addition, the Maricopa County Solar Initiative’s website improperly uses a modified version of the county seal, but the “Solar Initiative” is linked to a private business and is not associated with the county. The “Solar Initiative” is also not registered to do business in Arizona.

Similar flyers previously appeared in Clark County, Nevada, this summer, and law enforcement officials there have warned that the “Clark County Solar Initiative” notices are deceptive.

Arizona Attorney General Mark Brnovich has aggressively prosecuted businesses masquerading as government agencies, including obtaining consent judgments against “Mandatory Poster Agency” and “Compliance Filings Service,” resulting in full restitution for Arizonans totaling hundreds of thousands of dollars.

A picture of the “Public Notice” is below:

 If you believe you are a victim of consumer fraud, you can file a complaint online at the Arizona Attorney General’s website. You can also contact the Consumer Information and Complaints Unit in Phoenix at (602) 542-5763, in Tucson at (520) 628-6648, and outside of the metro areas at (800) 352-8431.

Arizona’s Salt River Project Utility Challenged On High Rooftop Solar Rates

In 2015 SRP became anti-solar when it adopted special solar rates (E27) with some high demand charges, etc.  SolarCity, later acquired by Tesla, challenged SRP’s discriminatory solar rates on antitrust grounds. SolarCity/Tesla took the case to the Supreme Court after a lower court rejected its request to dismiss the case. SRP reached a settlement with Tesla before the Supreme Court hearing, and the discriminatory fees were left in place. As part of the settlement SRP agreed to purchase a 25 megawatt/100 MW-hour battery energy storage system from Tesla. This meant that the basic reasons for the lawsuit, challenging the discriminatory rates, were not subject to court review and a chance to rule against SRP. The Center for Biological Diversity filed an Amicus brief against SRP’s motion to dismiss in order to have the Supreme Court consider the antitrust grounds.  

The SRP rates have been proven to stifle rooftop solar, reducing new installations in SRP service areas while installations in other areas of Arizona increased.  SolarCity claimed that SRP’s discriminatory solar rate structure is an obstacle to clean energy transition, because it undermines the value of homeowner investment in these systems. The solar rates were not examined by the courts, SRP basically claimed that it was exempt from regulation in this situation.

The Center for Biological Diversity is an Arizona-based non-profit environmental organization dedicated to the preservation, protection and restoration of biodiversity, ecosystems, and public health. On behalf of its more than 1.5 million members and online activists nationwide, including more than 890 members, and over 15,000 supporters, who live in SRP service territory, the Center advocates for a rapid transition to a clean and just energy system that optimizes renewable energy sources such as distributed solar in order to reduce U.S. greenhouse gas (“GHG”) emissions and combat climate change.

The Center filed an Amicus brief to present three discrete arguments against SRP’s motion to dismiss. First, SRP should not be permitted to rely on state action immunity to shield its discriminatory rate structure from antitrust liability, and certainly not at the pleading stage. Second, state-action immunity for utilities like SRP should in any event be constrained to open the door for distributed solar competition. And finally, SRP is violating the Equal Protection clause because its anti-solar electricity rates have no rational basis.

SRP is proposing three new Price Plans for Rooftop Solar

SRP is proposing three new price plans for residential customers who produce their own energy with rooftop solar and other technologies. Two of these options have no demand charge associated with them. See the SRP Proposal. Be sure to open the 'View graphics'. Specific rates are not shown. There were rate setting board hearings for residential and business electric and solar customers in front of the SRP Board at the Arizona Heritage Center in Tempe on March 4th, 11th, and 25th at 9:30 a.m. Follow this link to learn more. The complete Proposed adjustments are available on-line. The new solar price plans are E-13, E-14 and E-15. The base E-27 'Customer Generation' Price Plan is not much changed.

UPDATE: SRP is considering another solar rate alternative.  The Arizona Republic has a good article on this in the 3-14-2019 issue:
