Case Study: Thomonde Hospital In The Central Region of Haiti

The Thomonde battery bank was designed for 40 percent depth of discharge and only one day of autonomy due to the large loads of some of the medical equipment and the availability of the diesel generator.

Making the Switch: From Fixed to Solar Tracker

I compared the cost per watt to install a standard pole mount, such as a DPW, and found it cost the same as putting up a standard tracker. And of course by tracking you get the additional power.

Interview with Sophie Parker of The Nature Conservancy

In areas of the Mojave that are ecologically intact, renewable energy development poses a major problem for plants, animals, and other species. Some major issues include: habitat destruction and fragmentation, water use, and bird mortality.

SolarCity Thrives in Solar Power Sector

Sun Concept, Ampulse, Evergreen, Solyndra: the long list of defunct solar companies is enough to give pause to anyone trying to enter the business. But at least one company, SolarCity, has been succeeding where so many others have failed. Its secret? Staying away from manufacturing and focusing on installation. SolarCity was founded in 2006 by Lyndon and Peter Rive, on the advice of their cousin, Elon Musk, the Paypal founder who went on to start Tesla Motors and SpaceX, and is enjoying something of a moment. Tesla Motors just posted its first quarterly profit. And SolarCity, which went public last January, has seen its stock more than triple. Instead of designing solar panels, the Rive brothers decided to find ways to get solar panels onto people’s roofs. They settled on a sort of lease arrangement: SolarCity installs the panels for free on customers’ roofs and then sells them the energy the panels produce for the next 20 years, at a rate lower than charged by the local utility. As the owner of the panels, SolarCity also reaps the valuable tax credits associated with clean-energy production. This business model, with high upfront costs for gradual returns spread out over decades, doesn’t lend itself to immediate profits. On Monday, the company posted a $31 million loss. So far investors seem patient.  “The stock is outperforming the results,” an analyst for Raymond James & Associates told Bloomberg. Lyndon Rive, in an interview with CNN, pointed out the irony that as soon as SolarCity show a profit, it’ll be a warning sign that recurring revenue has outpaced installations and the company has stopped growing.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
