  • How Solar Works

    There are four basic components of a simple grid-tied solar array. The first component is the solar panel itself. Panels are usually wired through a combiner box and that wiring is then sent down to an inverter. The panels are held in place by racking. Read more.


  • Solar Energy and Storage

    While the prospect of selling excess back to the grid is attractive in theory, it basically limits the way an array is utilized since in a purely grid-tied situation, when the grid goes down, the solar array stops producing. Read more.


  • 10 Fun Facts about Solar Energy

    When we all talk about solar energy as a solid renewable energy solution, we quote a lot of figures, a lot of specifications and a ton of data. Here’s some non- technical interesting and fun facts about solar energy that aren’t necessarily common knowledge. Read more.


  • The Import Tariff and the U.S. Solar Industry

    For quite some time now, we’ve heard talk about the upcoming import tariff on Chinese-made solar panels being the “right thing” to do to support the U.S. job market. While in theory the ideal of limiting any product that floods the U.S. market taking away manufacturing jobs from U.S. companies is generally sound, this particular line of thinking doesn’t hold muster when applied to the U.S. solar industry.

  • A New Road for Solar

    There are those that think within the box, those that think outside the box and those that choose to throw the box away entirely. Such is the case with some recent conceptual thinking utilizing solar. Read more.


  • The United States and the Solar Industry

    2013 was another record year for the U.S. Solar Industry. There were 4,751 MW of new photovoltaic capacity installed ins 2013, representing a 41 percent increase in deployments over installation levels in 2012. Read more.


  • Solar Power and the Workforce

    When you talk to most people about the Solar Industry and the impact it has on America, you’ll probably get answers spanning the gamut from end user offsets of grid power to White House initiatives for Solar Energy. What you probably won’t hear is the effect that the solar industry has on the workforce in America. Read more.


  • Public Energy Policy Sets the Stage

    The three necessary components for renewable energy success, innovative technology, reliable financial tools and sound public policy, have been written about quite a bit by me and others. Technological innovation continues, adhering nicely to Moore’s Law, and better financial tools are providing new ways to pay for projects and capitalize companies. Today, let’s look at a public policy success, or at least what appears to be a success. Read more.


  • Energy Storage: The Next Big Deal Part 2

    We recently looked at advances in energy storage technology which are approaching commercialization, moving from the lab to the marketplace. These developments are accelerating the adoption of storage for electricity produced using variable renewable sources, a long-sought-after grail in renewable energy. Now let’s look at some policy and market trends that are also helping catalyze that commercialization. Read more.


  • Energy Storage: The Next Big Deal

    The most exciting segment of the renewable energy industry in early 2014 is energy storage. Technological advances, driven by market demand and catalyzed by public policy, are poised to bring an array of better, cheaper energy storage solutions very soon. There are indicators all around that we are at a tipping point in energy storage. Read more.

  • Increasing Power Density The Smart Way: Bussmann Series Low-Profile Compact Circuit Protector (CCPLP)

    In the data center, higher voltages mean improved power density, better use of space, and lower costs. There’s only one catch: increased risk of fault currents. When more power is delivered with lower impedance, fault currents can be much higher. To protect people and components, circuit protection must be incorporated across systems. That’s where Bussmann Series Low-Profile Compact Circuit Protector (CCPLP) comes into play. Learn more.
