The Renewable Energy Fund (REF), managed and administered within the Rhode Island Economic Development Corporation (RIEDC), has historically been the state's sole, dedicated source for renewable energy funding. The program provides grants, recoverable grants and loans for commercial, municipal and housing projects, as well as feasibility studies.
Currently, the PowerCube™ is configured as a behind the meter resource. In essence this means that Axion acts as a virtual generator by curtailing load. When the PowerCube is commanded to take load from the grid it uses that power to charge its battery. When commanded to discharge, the battery is discharged into the plants load effectively reducing or curtailing its power consumption.
In its first-ever dissection of a solar power inverter, IHS has determined the bill of materials (BOM) of a major manufacturer's product, providing a path-setting benchmark for cost reduction in a market expected to undergo rapid price erosion in the coming years.
Selling PV modules in their product package of glass and fenestration products represent a very significant sales potential increase for glass and glazing subcontractors. On a related matter, many PV modules can be glazed directly into the fenestration products without any modification to either product.
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.

Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter in 1997. Today, Sierra's completely redesigned InnovaMass® iSeriesâ„˘ 240i/241i builds on two decades of success measuring five process variables for gas, liquid and steam with one connection. Now, with the latest hyper-fast microprocessors, robust software applications, field diagnostic and adjustment capability, and a new state-of-the-art flow calibration facility, Sierra's vortex iSeries delivers precision, performance, and application flexibility never before possible.
