• 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.

Interesting Technology Updates;

This is an interesting approach to optaining very high penetration of renewables such as photovoltaics and wind.  At present most large installations operate under Power Purchase Agreements (PPA) wherein the economics are based on a sell all output at predetermined prices. This contrasts with standalone systems wherein the system size is based on meeting the load requirements all year.  This means that when output exceeds the load requirements, the output of the system is simply reduced and potential production lost.

A radical idea to get a high-renewable electric grid: Build way more solar and wind than needed

A look at some of the more significant changes under consideration for the 2020 National Electrical Code (NEC) that will affect future distributed generation systems (solar electric wind, etc.). Article 690, Solar Photovoltaic (PV) Systems and Article 705, being renamed Interconnected Electric Power Production Sources, are specific to distributed generation.

The referenced article below by IAEI, a membership driven, non-profit association promoting electrical safety, has a good summary of upcoming changes.

Movie Summary:

This video examines early efforts to utilize heliograph communications and solar energy in the state of Arizona and includes reenactments of their original uses. The heliograph was one of the first solar experiments in territorial Arizona. In the late 1880s, the U.S. Cavalry employed the heliograph during hostilities with native Americans. Solar developments in Arizona during early part of the 20th century are also explored, from the Eneas Engine and the Day & Night solar water heater to solar cookers and passive solar architecture. Pioneers Arthur Brown, John Yellot, Sherry Cole and Barbara Kerr are recognized for their contributions to solar development in Arizona and elsewhere.

Tucson Innovative Home Tour and National Solar Tour [Tucson]

From Saturday 10 November 2012
To Sunday 11 November 2012

The Tucson Innovative Home Tour and Tucson Solar Tour are annual non-profit, non-commercial, community educational events bringing people together to share ideas and experience in the search for ways to make homes better and cost less. You can see sustaining homes that fit in well with the natural environment, homes that draw on the best aspects of the local climate for greater comfort with much lower utility bills, and homes with quality and durability for a greater affordability that lasts. In short, it's about how to live in nature's sustaining flow, instead of trying to swim against it. New advances for designing, building and renovating such homes are the focus of the tour, recognized as one of the largest local events of its kind in the nation.
