Are Solar Companies Ripping You Off?

Members of Congress and a big utility are teaming up to raise that question. But experts think their concerns are overblown. Solar panels on the roof of a house in Apache Junction, Arizona. Darryl Webb/AP Back in December, a group of Republican members of Congress from Arizona and Texas sent a worried letter to the Federal Trade Commission. Solar panel companies, the letter claimed, might be using deceptive marketing practices to lease their rooftop systems to homeowners without fully disclosing the financial risks. The concerns were similar to those raised a month earlier by Democratic lawmakers—also from Arizona and Texas—in a letter sent to the federal Consumer Financial Protection Bureau. Both letters raised the specter of serious problems in the business model of the country’s fastest-growing energy source. But as the Arizona Center for Investigative Reporting revealed last month, the Republicans’ letter was originally drafted by an employee of Arizona Public Service, the state’s biggest electric utility and a long-time opponent of third-party solar companies. The draft was passed by APS to the office of Rep. Paul Gosar (R), which made a few changes, got the Congressman’s signature, and sent it off, according to AZCIR’s report. (The letter is here; the highlights were added by AZCIR to show where changes had been made from the original APS draft.) It’s not the first time APS has engaged in this type of secretive advocacy to undermine solar, an exploding industry that poses an existential threat to the old-school utility’s bottom line. In 2013, the company outed itself as the backer of two secretive nonprofits that ran an aggressive anti-solar ad campaign in the state. Back then, the company’s target was net metering, the policy that requires utility companies to buy excess electricity produced by its customers’ rooftop panels. Now APS’s focus appears to have shifted to the marketing practices of companies that lease solar panels to homeowners. “This is the next evolution in the utility playbook,” said Susan Glick, a spokesperson for The Alliance for Solar Choice, an advocacy group that represents some of the country’s biggest solar companies. APS wants “to demonize rooftop solar and ensure they have a monopoly,” she said. The cost of rooftop solar systems has plummeted in recent years. But some solar companies have realized that many homeowners are still unable to pay north of $10,000 to buy and install panels. Instead, the trendy option is solar leasing: A company installs panels on your roof for free and then charges you a monthly fee for the power they produce, which in theory is less than what you paid your electric utility. A recent industry survey found that about half of all residential solar systems are leased rather than owned. A spokesperson for Rep. Ann Kirkpatrick (D)—one of the authors of the Democratic letter—told Climate Desk that Kirkpatrick wanted to “take the lead” on the letter to the CFPB “after receiving numerous complaints about solar rooftop leasing practices in Arizona.” The spokesperson added that “any suggestion that the congresswoman issued the letter because of coercion by the utilities is false.” The APS-authored letter from Gosar and his GOP colleagues was more specific. It alleged that, as part of their rush to sign up customers before a federal tax credit expires, solar leasing companies have been overstating the savings that homeowners will receive. Neither Gosar’s office nor APS returned requests for comment. Both letters drew parallels between solar leasing and the subprime mortgage crisis, in which financial companies used shady lending practices to lure home buyers into mortgages they couldn’t really afford. It’s been a couple months now since the letters were fired off, and the response from the feds has been mixed. On Jan. 12 the CFPB responded to Kirkpatrick and her peers, writing that the agency is “currently studying a number of overlapping issues that may implicate the leasing of rooftop panels.” A CFPB spokesperson declined to elaborate on what exactly those issues are and whether these inquiries were instigated by Kirkpatrick’s letter. An FTC spokesperson said the agency had not yet taken any action on solar leasing. Back in Arizona, last month the state’s Corporation Commission opened a docket to collect preliminary information on solar leasing, with the possibility of a more thorough investigation in the future, a spokesperson said. So is the congressional prodding warranted, or just glorified lobbying for one freaked-out utility company? For all the noise, actual complaints against solar leasing companies seem to be relatively rare. According to the AZCIR report, Gosar’s chief of staff said he had not actually seen any complaints, and a spokesperson for Kirkpatrick “declined to answer questions about the quantity of reports, the way the reports reached their office, or to confirm that they reviewed any consumer complaints.” The Corporation Commission docket currently contains only one complaint, from a Scottsdale resident who claimed that “uneducated residents are bamboozled into these programs by unscrupulous businesses looking to make a quick buck.” That was essentially the complaint in a separate 2013 lawsuit against SunRun, a leading solar leasing company, brought by a California man who claimed he was misled about cost savings. SunRun denied the allegation, and that claim has since been dropped, the man’s law firm said. And a smattering of news outlets have reported cases of homeowners finding it more difficult than they expected to sell homes that are attached to a solar lease. But Travis Lowder, an energy finance analyst with the Department of Energy’s National Renewable Energy Lab, said complaints like this tend to be rare, isolated incidents that don’t reflect systemic flaws with the solar leasing business model. Lowder runs a team that has spent the last several years developing standardized contracts and practices for solar leasing companies. “The solar industry has been very proactive on consumer protection laws,” Lowder said. “They don’t want to put the consumer in the position where the consumer is going to default, because they need that cash flow” to support the large up-front costs of solar installations on other roofs. The biggest issue, Lowder said, comes down the long lifespan of a typical solar lease: 20 years. Over that time scale, a solar lease ultimately amounts to thousands of dollars of debt taken on by homeowners. What’s more, most lease contracts include terms that gradually increase the monthly fees paid by homeowners over time. The pitch to customers is that the solar fee rate will escalate less than the cost of grid electricity. (Over the last decade, the average cost of electricity nationwide rose 36 percent.) The problem is that it’s practically impossible to make iron-clad predictions about cost savings that far in advance. Unforeseen changes to US energy policy or to a customer’s local electricity market, for example, could potentially reduce savings from solar over the grid, while homeowners remain locked in to their original contracts. Energy investors and analysts make those predictive calculations all the time, but always with a number of assumptions about future market conditions and an appreciation for the built-in uncertainty. So the challenge is communicating that uncertainty to customers. Solar leases “are certainly not risk-free,” said Nathanael Green, a renewables policy analyst with the Natural Resources Defense Council. Still, he said, the agitation from APS is “almost without a doubt a politically motivated attack.” “That doesn’t mean it’s all nonsense,” added Green. “You have to separate out some of the silliness from the real things we can do a better job of.” Either way, courts and state and federal regulators will now have a chance to weigh in. Because Arizona is among the country’s largest solar markets, with a colorful history of conflict between incumbent power companies and their renewable rivals, the outcome there could set the stage for how solar leasing is treated elsewhere. Nicholas Mack, the general counsel of solar financing company Clean Power Finance, has worked with NREL on developing best practices for solar leasing. The solar industry will be ready if the government comes knocking, he said: “I do think we can withstand the scrutiny.”

NASA Found Propene, the Chemical Used to Make Your Tupperware, on One of Saturn’s Moons

Titan, Saturn’s massive, planet-like moon, is known for its seasonal weather patterns, sand dunes akin to those found in Africa’s Namib desert and hydrocarbon lakes. Now, the second-largest moon in the Solar System has gotten even more Earth-like: it contains propylene, an ingredient used in household plastics such as Tupperware and car bumpers.

This is the first time the common Earth chemical has been found anywhere other than on our planet, NASA reports. The chemical, found in Titan’s lower atmosphere, was detected with a composite infrared spectrometer by NASA’s Cassini spacecraft.

Titan’s atmosphere is mostly composted of nitrogen, followed by methane. Hydrocarbons like ethane and propane are also present. This new discovery fills in a gap in that chemical line-up, though experts suspect that many more molecular surprises await. The BBC reports, citing curious “colossal hydrocarbons” that have been detected:

When the effects of ultraviolet light are combined with the bombardment from particles driven in Saturn’s magnetic field, it becomes possible to cook up some very exotic chemistry.

Cassini’s plasma spectrometer has seen evidence for hydrocarbons with an atomic mass thousands of times heavier than a single hydrogen atom.

As for the propylene, the NASA project managers believe that ”this new piece of the puzzle will provide an additional test of how well we understand the chemical zoo that makes up Titan’s atmosphere.”

An Underwater Volcano the Size of New Mexico Is the World’s Largest

A massive volcano the size of New Mexico or the British Isles lurks deep beneath the Pacific, about 1,000 miles east off the coast of Japan. Called the Tamu Massif, scientists just confirmed that it is not only the world’s largest volcano (sorry, Manua Loa) but also one of the largest documented volcanoes in the solar system.

Researchers began studying the Tamu Massif, which is part of an underwater mountain range, about 20 years ago. But until now, they couldn’t determine whether it was a single giant or a cluster of multiple smaller volcanoes. A team from Texas A&M University (“Tamu”—get it?) confirmed the Tamu Massif was a single volcanic entity by studying its past patterns of lava flows and analyzing geochemical samples from the volcano.

National Geographic describes what we know about the volcano:

Tamu Massif is a rounded dome that measures about 280 by 400 miles (450 by 650 kilometers), or more than 100,000 square miles. Its top lies about 6,500 feet (about 2,000 meters) below the ocean surface, while the base extends down to about 4 miles (6.4 kilometers) deep.

Made of basalt, Tamu Massif is the oldest and largest feature of an oceanic plateau called the Shatsky Rise in the northwestern Pacific Ocean. The total area of the rise is similar to Japan or California.

Luckily for us, the volcano was only active for a few million years, NatGeo points out, going “extinct” about 145 million years ago.

A Galactic GPS System That’s Now in the Works Could Help Our Descendants Navigate Through the Universe

The International Space Station aims to be testing out an interplanetary GPS system by 2017, IEEE Spectrum reports. Rather than navigate with the stars or planets themselves, the system would rely upon the lingering X-ray pulses of dead stars to create a map of the galaxy.

At present, space navigation relies primarily on a network of earthbound tracking stations. When a craft ventures into deep space, ground crews beam radio waves out to the craft, which are then retransmitted back. By measuring the round trip time and the Doppler shift of the signal, the crews can calculate the craft’s position. But the further away the craft wanders from our planet, the poorer this method’s resolution becomes. So it follows that if a space vehicle could calculate its own position independently and accurately, its navigational capabilities would improve by leaps and bounds.

The new system aims to do just that. It relies upon the electromagnetic radiation emitted by pulsars, or technically dead stars that still give off bursts of oscillating energy. These pulses come at regular intervals, so they can be used for navigation in the same way GPS systems on earth use atomic clocks for standardization and accuracy.

A craft heading into space would carry a detector that, similarly to a GPS receiver, would accept X-rays from multiple pulsars and use them to resolve its location.

In order to test the system, the NASA team built the Goddard X-ray Navigation Laboratory Testbed (GXNLT). Nicknamed the “pulsar-on-a-table,” it’s composed of pulsar-processing software and hardware, a modulated X-ray source, and a built-in detector. The test bed tries to mimic the combination of an interplanetary GPS and pulsars.

If all goes well, a NASA engineer told IEEE Spectrum, these initial systems will lay the foundation for our descendants to navigate throughout our solar system and beyond.

Simple tips to construct your own solar power

As the actual increasing prices of power bills many of the property owner believes that how they can save their cash. Then people come to learn that they could produce power from their home through DIY solar panels which will save hundreds of dollar each month from spending these electricity bills. The original installation fees of these kinds of solar panels are high but it save from paying long term electricity bills which can be more worth that set up charges. Methods for making your own solar panel systems are explained in depth.

Solar panels are attached to solar cells which obtain sun rays on all of them and these types of cells will produce electrical power for house and for other household devices. These types of solar panels power is calculate as DC output which isn’t usable for home appliance and these DC output has ranged through 100 to 450 watts per solar panel which isn’t enough for home use so we have to install more panels to generate more electricity.

The best solar power system also have inverter which covert DC current output in to AC energy which could be use within homes in order to run these home electric products. The another thing that need is battery which is essential to save electricity inside it and uses at night or in rainy days where there isn’t any sunlight.

You also need the toolbox like, drilling machine, screw driver to combine one photovoltaic cell to other so that it’ll be in a row. We need wood glue or silicone to build solar panel on that these solar energy cells are put. Keep in mind that you must place this solar panel on the top of roof of your house where the actual rays of sunlight hit directly on these solar cell from that electricity will be created. Don’t place shed on top of the solar panel which may decrease the actual performance of making electricity. There are various people that are writing and submitting content articles concerning solar panels for their web site.

Everyone can make their very own solar panel system and safe their money for installing of these panels with the help of DIY Solar Panels.

Generate your own personal electricity with DIY Solar Panels

Solar Panels are effective and save your cash from paying every month electricity bills. These panels require onetime installation charges or you’re able to make it your self by using DIY Solar Panels. All these solar panel systems are safe and produce clean electricity as compared to the electrical energy made by gas or fuel. By working with DIY Solar Panels you’ll need several tools that you must buy from the market.

The first thing you will need for producing solar electricity would be the support frame on which solar cells will work and you should put on the top roof of the home exactly where rays of sun arrives straight. It is a sheet of copper where these cells operate, you can buy these sort of copper frame from market place very easily.

The 2nd tool you need is a solar cells which are produced from silicon and phosphorus. There are also several varieties of cells available at the market place but purchase those that are unbreakable. Place these cells on the solar panel and arrange them in a line, join every cell with electrical cable and be sure electricity easily moves from one solar cell to another.

Now you need larger battery that will store huge quantity of electricity inside it that is made from the solar cells. You can’t utilize this electrical energy directly to power up your home appliances. To convert this electricity you need inverter which will convert these electricity into useable electrical energy from which you are able to power up your house usage home appliances.

Right after getting every item now you have to get screwdriver and few iron nails. Make use of screwdriver and iron nails to connect solar cells with solar panel and connect them with electrical wire. Attach all of them using copper cable without damaging solar cells. Learn How solar panels work contain specific strategies on the subject of how to build solar panel.

If you follow above method then it will help you in saving your time and dollars. You could save great deal of cash by using above DIY solar panels instruction. Once you step-up solar power system you will end up saving lot of cash on paying power monthly charges.
