• 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

  • 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

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.

Renewable Energy Standard and Transition Plan (REST)

Stakeholder Meeting and Workshop March 10-11, 2020

Hearing Room One
1200 W. Washington St., Phoenix, AZ 85007

Commissioner Sandra D. Kennedy has submitted the Kennedy Renewable Energy Standard and Transition Plan II (KREST II), that calls for improving the existing REST to:

50 percent Renewable Energy Standard by 2028 and

100 percent Carbon Emissions Free Standard by 2045.

More Details


Utility Information

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.


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



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.

Past Initiatives in Arizona

Arizona Solar Initiative (1999-2001)

The Mission of the Arizona Solar Initiative was to encourage individual, local, and statewide action that capitalized on the national Million Solar Roof Initiative and the region's explosive growth. This Initiative sought to enable Arizona to become a national leader in solar energy utilization, manufacturing, and exports.

Goal 1: Establish an Arizona Solar Initiative sub-committee of the Arizona Solar Energy Advisory Council. The sub-committee will be comprised of invited parties and a representative from the Energy Office.

Goal 2: Install 100,000 new thermal and photovoltaic systems in Arizona by 2010.

Goal 3: Establish technical capabilities to utilize solar in government and non-government application.

Goal 4: Educate consumers about the benefits of using passive and active solar systems.

Goal 5: Coordinate industry and government efforts to overcome institutional barriers.

Goal 6: Develop and support solar manufacturing capacity in the state.

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 roof-top solar panels. The judge found that the association's "guidelines combined with [its] conduct 'effectively prohibited' the defendants from placing solar heating devices on their residence, contrary to the provisions of A.R.S.-33-439 (A)." The opinion can be reviewed at GARDEN LAKES COMMUNITY ASSOCIATION INC v. MADIGAN.

Senate Bill 1254, enacted in July 2007, stipulates that a homeowners association may not prohibit the installation or use of solar-energy devices (panels and associated devices). An association may, however, adopt reasonable rules regarding the placement of a solar device if those rules do not prevent the installation of the device, impair the functioning of the device, restrict its use, or adversely affect the cost or efficiency of the device. The bill also grants reasonable attorney fees to any party who substantially prevails in litigation against an association's board of directors.

The Arizona Legislature passed ARS-33-439 in 1979 in order to protect individual homeowners private property rights to use solar energy.
