  • The Grid vs. Rooftop Solar

    The development of solar micro-grids and mini-grids in the remotest parts of Australia seems to be a rational step in the right direction economically. However, network operators all over the world are still in doubt when it comes to the vast population in urban areas adopting similar methods. The question lies with the homeowner choosing to buy the necessary power generating equipment ...

  • NexGen, Bella Energy to develop 2.6 MW rooftop solar project in Utah

    NexGen Energy Partners, LLC (Boulder, CO) and Bella Energy (Louisville, CO) have received a contract from Salt Lake County in Utah to design and install a solar power installation on the roof of the Calvin L. Rampton Salt Palace Convention Center in downtown Salt Lake City. NexGen and Bella have presented a plan to install up to 2.6 MW of solar modules on the building—a capacity ...

  • Near Term Lower Cost Solar Electric Power for US Commercial Customers

    Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

  • Community Solar Garden Powers Ontario Homes & Businesses - Case Study

    Overview: A new analysis from the National Renewable Energy Laboratory finds that shared photovoltaic (PV) solar systems — also called community solar gar- dens — could account for one-third to one-half of all solar PV power in the United States by 2020. These shared community solar systems greatly benefit the many business- es and homes (especially rental properties) ...

  • A brighter future for solar in Texas

    I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...

  • Go Solar Successfully With These Tips

    Installing solar systems in residential areas on a domestic level is a common sight nowadays. All solar power generation units basically work by converting sunlight in to electricity using photovoltaic cells. Over time, there have been considerable leaps in the technology levels of this invention. This environment free power source with minimal maintenance or everyday cost is now being rapidly ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...

  • Solar`s Time to Rise and Shine.

    Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the ...

  • How to grow a solar energy garden

    Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004.  The engineer and serial entrepreneur wondered how he could replicate his ...

  • Chinese Solar Energy Market Analysis to 2014

    This  latest market research report titled Solar Energy in China 2014 states that the market is expected to witness rapid growth owing to favorable policy environment in the country. With the country facing a continuous shortfall in the supply of conventional sources required to meet the increasing demand for energy in recent years, the focus is gradually shifting from conventional to ...


  • Germany’s solar subsidy amendments switch demand from fields to roofs

    Germany’s upper house of parliament took the decision last week to back some key changes to solar power subsidies, making private dwelling rooftop solar power systems far more attractive this summer. Last May, the German coalition government had proposed cuts of 16% in the so-called feed-in tariffs offered for such rooftop solar panels.  They included plans ...

  • Plan B 4.0 by the numbers - data highlights on solar energy

    Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. Harnessing some of this energy is an essential component of Earth Policy ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...
