Rooftop Solar: Resources to Help Determine if your Home is a Candidate

  • July 5th, 2016
  • admin

As you begin your solar journey, one of the first steps is to determine whether your home is a candidate for rooftop solar. Several resources are available to give you an early assessment of the feasibility of solar for your house. Though a solar professional will evaluate multiple factors like roof type, roof condition, the direction your home faces, and the region you’re in, solar calculators and estimators are a good way to begin setting realistic expectations for how a solar power system could contribute to your energy needs. read more…»

Solar Thermophotovoltaics Surpass Theoretical Efficiency Limit

  • June 8th, 2016
  • admin

Just a few years ago, solar thermophotovoltaics (STPV) was more of a theory than an actuality. The idea behind STPV is that the efficiency of solar modules will improve significantly if certain materials are used to trap the sun’s heat before it reaches the module. Photovoltaics, however, have always had certain limitations, as they can convert only a portion of sunlight into electricity. Since 1961, this limit—known as the Shockley-Quiesser limit, was thought to cap a solar cell’s efficiency around 32 percent. read more…»

Paris Climate Agreement Signed: The Role of Solar in Reducing Rising Temperatures

On Earth Day, 175 nations—including the United States­—signed the Paris Climate Agreement. In this landmark agreement, some of the world’s biggest carbon emitters agreed to limit global warming to at least 2 degrees Celsius above pre-industrial levels, according to Chemistry World. This is an ambitious goal that will require most of the signing countries to improve and increase their sustainability efforts.

Though the climate agreement has been signed, it now needs to be ratified by each of the member nations. Some forecast that this process could be delayed for some countries, particularly for the U.S. in the midst of the presidential election, but fifteen nations had their ratifications ready immediately after signing according to the United Nations. read more…»

Oregon Cutting Coal by 2030: How Solar Can Fill the Gap

  • April 15th, 2016
  • admin

In an important move toward clean energy, the Oregon state legislature recently passed a bill called the “Clean Energy and Coal Transition Plan” that will wean the state off coal completely by 2030. This huge step shows that the U.S. takes its carbon reduction commitment seriously and paves the way for more states to follow suit with clean energy plans of their own. read more…»
