• 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

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!”

SRP is proposing three new Price Plans for Rooftop Solar

SRP is proposing three new price plans for residential customers who produce their own energy with rooftop solar and other technologies. Two of these options have no demand charge associated with them. See the SRP Proposal. Be sure to open the 'View graphics'. Specific rates are not shown. There will be rate setting board hearings for residential and business electric and solar customers in front of the SRP Board at the Arizona Heritage Center in Tempe on March 4th, 11th, and 25th at 9:30 a.m. Follow this link to learn more. The complete Proposed adjustments are available on-line. The new solar price plans are E-13, E-14 and E-15. The base E-27 'Customer Generation' Price Plan is not much changed.

UPDATE: SRP is considering another solar rate alternative.  The Arizona Republic has a good article on this in the 3-14-2019 issue:

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:

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.

Solar Cooking

   

Solar cookers are simple, low cost and effective.  They are basically insulated enclosures with a clear top to allow sunshine to enter.  The sunshine is absorbed by both the food and a black surface, heating up the enclosure and cooking the food. Reflectors can be used to increase heating by allowing more sunshine to enter the cooker.

Learn more about solar cookers by following the links below.

Photovoltaics Birth

The Birth of a Technology

In 1955, using crystalline silicon, scientists at Bell Laboratories fashioned an enormous solar cell capable of turning six percent of the sunlight that struck it into electricity. Soon the efficiency was raised to eleven percent and scientists realized that the new devices could have practical applications. They had another reason for optimism; the material they were using, silicon, is the world’s second most abundant element, comprising 28 percent of the earth’s crust.

These achievements were greeted with much fanfare amid the technological developments of the 1950s. Solar cells seemed to promise an unlimited supply of electricity and roused considerable excitement. A 1957 article in “Business Week” envisioned an automatically controlled solar car in which “all riders could sit comfortably in the back seat and perhaps watch solar-powered TV.”

U.S. News and World Report said that the silicon solar cell "may provide more power than all the world's coal, oil and uranium."

The New York Times said the discovery "may mark the beginning of a new era, leading eventually to the realization of one of mankind's most cherished dreams -- the harnessing of the almost limitless energy of the sun for the uses of civilization."

It was an unfavorable time, however, to develop a new energy technology. Oil was priced at less than $2 per barrel, and large fossil-fuel power plants were being built at a record pace. Moreover, in 1954 construction began on the world’s first commercial nuclear reactor. Nuclear power was envisioned as a source of electricity “too cheap to meter,” and most government energy funds were devoted to that technology.

Photovoltaic researchers also faced an unsettling economic reality. Silicon cells developed in the 1950s were extremely expensive, with costs as high as $600 per watt (compared to less than $1 today). Funding for research to reduce the cost was not available in an era with falling electricity prices and minimal concerns about the environment.

The space program rescued photovoltaics from the technological scrap heap. American scientists in the late 1950s went searching for a lightweight, long-lasting power source for satellites. Photovoltaic cells, which could take advantage of the continuous sunlight of space, were their choice. In 1958 just four years after the Bell laboratory breakthrough, silicon solar cells were boosted into orbit aboard Vanguard I, the second U.S. Satellite.

With the help of large contracts from the National Aeronautics and Space Administration (NASA) four U.S. commercial companies enter the photovoltaics business and by the late 1960’s were producing hundreds of thousands of solar cells a year. Amid the heady competition of the post-sputnik space race, the Soviet Union began equipping its satellites with photovoltaics as well. Today, solar cells power virtually all satellites.

Achievements in photovoltaic cell research during the peak years of the space program included a major increase in efficiency and reduction in cost. However, the space-related PV market leveled-off and photovoltaic cell production declined.

In 1973, America was jolted by its first oil crisis – gasoline prices soared and interest in alternative fuels was awakened. Beginning in 1975, the U.S. government funded a steadily growing research and development program aimed at making photovoltaics economical for terrestrial use. Japan and European countries followed suit. Perhaps a dozen private companies entered the solar cell research or production business.

Over the next quarter century, the overall market for photovoltaic technology increased dramatically. In the last five years alone, from 2010 to 2015, more photovoltaic systems have been deployed than in the five previous decades coming after the Bell Labs discovery.
