  • 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

  • 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 Read more

    Photo shows the situation after a battery discharge test at 300 amps was terminated on a 1530 AH IBE battery string when one post melted. During the discharge test all cell voltages are logged. The sum of the cell voltages was 2.73 volts lower than the 48-volt string voltage. This is an average of 118 mv per inter-cell connection, 5-10 Read more

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.

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. 

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.

Upcoming:

Green Building Lecture Series

Future Proofing and Preparing for the Electric Utility of the Future

Date: Thursday, Dec. 6

Time: 7 - 8:30 p.m.

Location: Scottsdale Granite Reef Senior Center, 1700 N. Granite Reef Road (northwest corner of McDowell and Granite Reef, behind the convenience store)

Since electric lights first appeared in buildings, the electrical grid and buildings have had an important relationship. To date, the relationship has been one-sided - the grid provides electricity and buildings have been passive consumers.

Renewable energy coupled with energy efficiency provides multiple benefits including distributed (decentralized) energy, lower energy costs and reducing the need to build more electric power plants. Energy efficiency alone is among the most cost-effective ways to reduce carbon emissions, making it a part of fighting climate change. Hear about the role you can play in this transformation to reduce environmental impacts and improve the prospects for a bright future with the buildings we live and work in.

Speakers:

Jeff Grout is a senior energy consultant and project manager who has been working on energy efficiency projects with large commercial and industrial customers in Arizona for over 10 years. His experience includes many energy efficiency projects, energy audits and working on demand response and demand side management programs with major utilities from coast to coast. As an active participant in the clean energy revolution, his current dream is to see Arizona become the solar power leader that it is destined to be.

 

This lecture is one in a series that includes:

Feb. 7, 2019 - Living an Edible Landscape Life

April 4, 2019 - Radiant Cooling and Other Alternatives to Conventional Air Conditioning

June 6, 2019 - Cutting Edge Residential and Commercial Green High-Performance Buildings

 

Admission: The lecture series is sponsored by the Scottsdale Green Building Program. The lectures are free and open to the public; no reservations are needed.

Contact: Anthony Floyd, green building program manager, city of Scottsdale, afloyd@ScottsdaleAZ.gov, 480-312-4202.
