  • 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 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 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 Read more

Some things to pay attention to in Arizona

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.

Arizona pro-solar ballot measure fails (after crazy $40 million in spending)

Clean energy advocates Tom Steyer and the NRDC thought they had a winner with Arizona’s Proposition 127, which would have saved consumers money while helping the environment. But a huge burst of negative advertising by a local utility drove the measure down to defeat, while making this the most expensive Arizona election ever at $40 million.

By Charles W. Thurston
Cleantechnica


Proposition 127 required utilities operating in the state to source 50% of their energy from solar, wind, and other renewables. The state renewables energy portfolio standard is now 15% by 2025.
Clean Energy for a Healthy Arizona, a group backed by environmental advocate Tom Steyer, filed the proposal as an amendment to the state constitution that would require utilities to increase their renewables generation percentage by about 4% per year starting in 2020, with a minimum of 50% by 2030 and thereafter.

Clean Energy for a Health Arizona identifies itself as “a coalition of organizations and individuals, including Arizona doctors, nurses, labor unions, and small businesses, who know that this measure will improve public health and create good jobs for Arizona.”

Arizona Public Service, the largest utility in the state, opposed the amendment on the grounds that it would force the utility to retire existing non-renewable assets ahead of planned lifetime, stranding assets that might or might not be recoverable from the Arizona Corporation Commission.

APS serves about 2.7 million people in 11 of Arizona’s 15 counties. With headquarters in Phoenix, APS is the principal subsidiary of Pinnacle West Capital Corp.

While the utility is relying on new gas plants for its currently filed growth plans, it also has plans for more renewables in the future. APS issued a “peaking capacity” request for proposals in April for approximately 400-800 megawatts of capacity to meet peak demand beginning in 2021, specifically during the months of June through September. “APS will accept proposals for power purchase agreements for delivery to the APS system beginning no later than June 1, 2021,” according to the company RFP. APS also plans to issue other RFPs to solicit forest bioenergy solutions and battery retrofit opportunities for APS-owned solar facilities.

Jeff Deyette, the director of state policy and analysis for the Union of Concerned Scientists, said on November 5, “When Arizonans go to the polls tomorrow they’ll have a tremendous opportunity to take control of their energy future and put the state on the path to a much cleaner, healthier, more affordable power supply.”

Deyette adds “A recent study found that achieving the renewable energy requirements under Proposition 127 could save Arizona consumers as much as $4 billion between 2020 and 2030. That’s because the cost of solar and wind have dropped dramatically to the point where they are cheaper than new investments in fossil fuels, especially in places with strong resources like Arizona.”

The study was commissioned by the Natural Resources Defense Council (NRDC) and performed by energy analyst ICF. The study found that average electricity bills in 2030 would be $3 a month lower if Arizona pursues a high-renewables future, and $5 a month lower in 2040. The report was based on assumptions provided by NRDC based on publicly-available sources, the organization said.

The Solar Energy Industries Association assesses the solar policy climate in Arizona dimly: “While Arizona solar industry has tremendous growth opportunity, due to public debates about the benefits of solar, imposition of a net metering charge in 2014 and elimination of incentives, the market has been turbulent. SEIA is working with local stakeholders and policy makers to encourage stability and transparency into policies, so that the market can recover from this market disturbance and continue to grow.”

APS already has 10 solar generation plants in the state with a cumulative 1 million solar panels, and overall, 50% of the energy provided to customers is clean energy, including the Palo Verde nuclear station, the utility reports.

Arizona now has 3.6 GW of solar installed at an estimated cost of $8.2 billion, as the state with the third most installed solar generating capacity. About 536,000 homes in Arizona are solar powered, making solar energy the source of about 6% of the state’s total electricity generation by source, according to SEIA.

Navajo Nation Eyes Utility-Scale Solar with Growing Interest

Momentum is growing around modernizing tribal renewable-energy policies on the Navajo Nation of Arizona, Colorado, New Mexico and Utah, according to a report published today by the Institute for Energy Economics and Financial Analysis.

By

The report —“Growing Interest in Developing Navajo Utility-Scale Solar Industry: Policy Momentum and Grassroots Support; Vast Tribal Natural Resource Remains Largely Untapped”— details movement on three fronts:

  • In an evolving tribal utility policy toward more utility-scale solar, a shift driven in part by the success of the Kayenta Solar Facility, a 27.3MW, 200-acre project that came online in 2017 and is now feeding into the regional grid. Kayenta, seen as a pilot for similar initiatives, is also serving as a training ground for large scale solar-installation-and-construction expertise.
  • In central tribal government support for more solar infrastructure in general, including for community-owned solar farms that allow for revenue streams to be shared with local tribal chapters and land owners. Of note on this front: The creation in recent weeks of the Office of Energy Resources and Development.
  • In campaigns to bring community-owned solar projects into locales that have access to key transmission lines and where ownership models are expected to include revenue streams for the Navajo Nation and local tribal chapters alike.

 The emerging interest in utility-scale solar is driven in no small part by the large-scale deployment of solar generation throughout the Southwest, and the report notes how Navajo lands remain something of an island in a growing regional sea of utility-scale solar installations.

Another factor driving the more aggressive pursuit of utility-scale uptake: The likely closure of the coal-fired Navajo Generating Station, a major employer and tax-base component.

The report concedes that a Navajo solar industry could be one building block in a post-coal economy.

“While utility-scale solar is not seen as a replacement for NGS job and revenue losses, it can be a component of a new tribal energy economy that can bring distributed economic benefits and greater energy independence to the region,” said Karl Cates, an IEEFA research editor and author of the report.

On the community-solar front, opportunities are seen now at Cameron, LeChee, and Kayenta. Navajo National officials are modernizing energy policy to help encourage development of more renewables. And NTUA officials say they expect to install more utility-scale solar across their jurisdiction.

Development openings are appearing fast, and the report builds on one previously published by IEEFA and Diné Innovative Network Economies in Hózhó that said:

“As the solar-industry footprint expands, Navajo communities are being courted by outside interests to participate in fast-moving development deals. The Navajo Nation, only 67 years old and built from a history of trauma, is not well-equipped to assess these opportunities, but tribal-chapter communities can get up to speed with proper advice and consultation.”

While few locales in the U.S. are richer in solar potential then the Navajo Nation, few models for utility-scale solar generation exist yet on tribal lands.
