• 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

ASEA REBOOT

The Arizona Solar Energy Association (ASEA), State Chapter of the American Solar Energy Society ASES), will be holding meetings in a follow-up to the-long awaited updated ASES‚  Chapters handbook and directives.

ASES evolution, in response to some problematic economic and operational conditions, has resulted in a hearty and robust context for the present and the future. ASEA is now responding with an appropriate updating, through local and statewide discussion. 

Interim Chair, Andy Gerl, a past ASEA Chair and Board member, is making arrangements for Arizona solar advocates and supporters, members and non-members, to receive both an update re: ASES adaptation and changes, and to discuss solar in Arizona and the “reboot" of the ASEA  context, goals and objectives, within the context of varied renewable energy groups within the State, such as AriSEIA (the solar trade association); various sustainability groups; Green Building organizations; the recently formed solar hot water businesses non-profit entity; research and development at the universities; and others.

For more information about the ASEA Reboot discussions, contact Andy at andrew@blazingsolar.com  or 602-799-5942

Environmental Achievement Recognition Award

Call for Entries

Is your business or organization a sustainability leader? The city of Scottsdale wants to honor your exemplary achievements.

The Environmental Quality Advisory Board is accepting nominations for its next Environmental Achievement Recognition Award. The award honors environmental excellence in areas such as green building, resource conservation and waste reduction. Eligible candidates include businesses, associations and organizations located in Scottsdale. Learn more about the award program and nominate a worthy candidate.

Past Award Recipient - Hyatt Regency Scottsdale Resort & Spa at Gainey Ranch

The Board's inaugural award recognized Hyatt Regency Scottsdale for the resort's many and diverse accomplishments that were "designed, engineered, cost analyzed and then approved by business executives because the return on investment made sense." The Hyatt was originally designed and constructed in the late 1980's. It was not until 2009 that a concerted effort was made towards energy efficiency and other green improvements starting with the installation of  a cool roof and solar thermal (hot water) system. The cool roof showed immediate results by reducing interior temperatures by 8-10 degrees, while the solar thermal panels supplied 100 percent of the domestic hot water used in the resort, providing for significant energy savings.

The green transformation continued with renovation of the guest rooms and other interior spaces, including installation of LED lighting, thermostats linked to occupancy/vacancy sensors, high efficiency plumbing fixtures, and textiles made with recycled materials. Seventy percent of the removed fixtures, textiles and building materials were recycled or donated to local organizations for reuse. Recycling containers were strategically placed throughout the resort, including every guest room.

The resort's Canyon Market began selling refillable beverage containers in lieu of plastic bottled water and water stations were installed  throughout the property. 28,000 square feet of turf grass was replaced with artificial turf resulting in 3.8 million gallons of water saved annually. The turf conversion also  increased the marketability of these areas as event spaces, thereby increasing revenue opportunities. The parking area was retrofitted with LED lighting and equipped with free electrical vehicle charging stations for guests and associates.

As a result of these and other improvements over a seven-year period, the Hyatt team reduced consumption of electricity by 20 percent, natural gas by 30 percent and water by 25 percent; and increased recycling by 15 percent.

Congratulations again to the Hyatt Regency Scottsdale Resort at Gainey Ranch!

Home batteries: What are they, and is it worth it for you to get one?

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.

Should you install solar on your home? 10 key considerations

Arizona's endless sunshine continues to make rooftop solar panels an enticing proposal for homeowners. Already, tens of thousands of Arizonans have installed panels to make electricity for them, and falling prices and new financing options continue to draw consumer interest.

But homeowners should consider several questions before deciding to install rooftop panels. Here are 10 primary considerations you should think about before signing a contract:

White House seeks 72 percent cut to clean energy research

The Trump administration is poised to ask Congress for deep budget cuts to the Energy Department’s renewable energy and energy efficiency programs, slashing them by 72 percent overall in fiscal 2019, according to draft budget documents obtained by The Washington Post.

Many of the sharp cuts would probably be restored by Congress, but President Trump’s budget, due out in February, will mark a starting point for negotiations and offer a statement of intent and policy priorities.

Mandalay to build 3,000 Arizona homes with solar and Sonnen batteries

(Reuters) - German battery maker Sonnen GmbH on Thursday said it would partner with home builder Mandalay Homes to outfit 3,000 new Arizona homes with batteries to store the excess energy generated by their rooftop solar installations.

Mandalay plans to build the homes in Prescott, Arizona with the batteries, which can cost between $10,000 and $20,000. The cost would be part of the home’s sale price and wrapped into the mortgage.

The companies want utilities to pay the homeowners to use the stored power in the 3,000 batteries, which would create a virtual power plant with 8 megawatt hours of electricity, enough to power about 5,000 average homes for a day.

For now however, the project is moving forward without buy-in from utilities. Sonnen’s U.S. arm and Mandalay have been in talks with Pinnacle West Capital Corp’s Arizona Public Service and Salt River Project for a few months, they said.

The community would be the first of its kind in the United States, the companies said, and comes as utilities have been studying the potential benefits of integrating battery storage along distribution grids and decreasing reliance on centralized fossil fuel plants. Sonnen has several such communities in Germany, but the idea is still a novelty in the United States.

Batteries are viewed as especially key in large solar energy markets like Arizona that generate more power than they need during the sunniest times of the day.

Sonnen has about 1,000 home batteries deployed in the United States currently, and aims to get to at least 20,000 by 2020, in part through more deals with homebuilders.

Arizona Public Service would not comment on talks with Sonnen and Mandalay, but said batteries “can provide benefit to both our customers and the grid.”

Salt River Project spokeswoman Kathleen Mascarenas said “no agreements are in the works.”
