MIT report shows that with new policies, U.S. electric grid could handle expected influx of electric cars and wind and solar generation.
Unirac is a strong advocate for developing new codes for solar infrastructure, and has been working closely with the International Code Council Evaluation Service to develop new performance standards for racking and mounting systems. Unirac's new SolarMount (E)volution residential roof mount PV racking system, launched at Solar Power International in October, is currently being evaluated by ICC-ES. Unirac is the first company to apply for an ICC ESR under ICC-ES AC428.
The solar industry is ready for its moment in the sun: Here at home, we hope fairness prevails so that the investigatory process proceeds without acrimony, political overzealousness or protectionism; at stake are U.S. jobs, U.S. exports, and U.S. consumer benefits for a strategically important U.S industry
Both thin film and crystalline solar technologies provide reliable and impressive energy production performance. While it is well known that amorphous silicon modules suffer lower performance loss in high temperatures and low light conditions, this study reveals that the differing mounting requirements of each system more than offset this cell-type difference. As a result, with commonly-used commercial mounting solutions, crystalline modules actually outperform thin film modules in energy production per rated watt.
Solar cogeneration of electricity and hot water maximizes the economic and environmental value of energy derived from the sun. Cogenra's system produces as much electricity as photovoltaic (PV) technology allows, then captures most of the remaining energy as hot water, in total exploiting over 70% of the energy incident from the sun.
The program's goals are nothing if not ambitious, as the government had initially hoped to boost the nation's solar capacity by the equivalent of about 18 nuclear power plants by 2022, a date that's now been brought forward by five years.
Sade's idea was to eliminate the need for masts or poles to secure a solar array to concrete foundations. Instead, the tracker would use a ballast pan filled with dirt, gravel or sand.
During the conversation, I kept coming back to ‘Why? What was driving this desirable business behavior?' Larry summed it up. "At the end of the day - we work to do as much right as we can for all concerns. By being long-term, we can look at the long-term win-wins for both conserving our resources and with a competitive long-term cost benefit as well.
We believe that system owners and installers should take an active role in understanding how their system is performing and that basic web based monitoring should be free and flexible. Adhering to this philosophy, we have designed the ZigBee based monitoring solution for the PV Powered HE string inverter to make string inverter performance monitoring fast, easy, simple, reliable and flexible.
A grid-interactive PV system implies that a PV system is tied to the grid but can stand alone if the grid goes down. Essentially, it offers the best of both off-grid and grid-tied systems.
This new type of architecture has inherent cost and reliability advantages over microinverters: it uses fewer critical components than microinverters, its easy installation and connection to the grid allows for reduced installation and maintenance costs and its connection to the module at a cellular level means the performance and cost of the solar module can be optimized.
Making affordable financing options available to as many people as possible is the key to stimulating widespread adoption of residential solar. That's why Clean Power Finance offers affordable financing options for qualified installers and homeowners as well as our CPF Tools residential solar sales platform to simplify, streamline and speed up the permitting process.
Caught between strong utility-scale project demand, declining solar incentives in distributed generation applications, module over-supply, and significant policy uncertainty, the North American photovoltaic (PV) market is at a crossroads, according to the conclusions of the recently-released NPD Solarbuzz North America PV Markets Quarterly report.

Consolidation is on the cards as the US market is undergoing correction and the Chinese wind market is expected to stabilize during the forecast period. Companies have modest expectations of growth for 2011 as major markets have slowed down but are expected to pick up in the second half of year.
We have a long way to go before AV, lighting, HVAC, and appliances come together within a home automation network that will work with smart meters and the utilities' back office system to communicate both ways flawlessly, controlling how and when energy is wisely consumed. Strides are being made in each area and we will see more systems coming together for the perfect balance of energy consumption and energy savings.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
