This article reviews the recent history of PV monitoring; the shift from single-meter systems to module-level control using highly reliable electronics, and future direction of the industry towards active system management from utility-scale solar farms down to the residential PV system.
Third-generation thin-film solar devices are beginning to emerge in the marketplace after approximately 20 years of research and development, due to the insight of leading material developers such as Konarka and Plextronics in the organic photovoltaics (OPV) domain, and Dyesol, EPFL, G24i, Mitsubishi and Peccell on the dye-sensitized cells (DSC) front. Both DSC and OPV technologies lag far behind on the efficiency curve when compared to conventional solar (i.e., >20 percent efficiency), so they will likely succeed in markets where their low cost, substrate flexibility, and ability to perform in dim or variable lighting conditions provide them with a significant competitive advantage.
We hope this short overview of N2Solar will give a good sense of what we are about, can accomplish in the markets, and the needs to get there. We welcome your questions and look forward to discussing the merits of our projects and how outside financial participation could benefit..
There are six main building blocks of a solar-LED lighting system, basically representing the main energy-conversion steps required to capture energy from the sun, store it, and convert it to nighttime lighting.
The three leading countries -- Germany, Japan and the USA -- represent almost 89% of the total worldwide PV installed capacity. Could these countries' renewable energy political decisions provide a model for the rest of the world?
How far the current PV cost is still separated from grid parity depends largely on the geographical situation, on the price of grid electricity, and on whether it concerns a cheaper or a more expensive PV system.
Sun Run owns and maintains the panels, not the homeowner, eliminating the hefty upfront cost and maintenance woes. Once the system is installed, Sun Run provides monitoring, all required maintenance at no additional cost and guaranteed system performance - or your money back.
We have seen the solar programs serve as a source of community pride for residents and a bonding agent between neighbors. When you make a big decision like going solar as a group, it also tends to remind residents of the larger impact of their decision on the environment and the fight against global warming.
Grid-tied PV systems without energy storage do not reduce load in a substantial and predictable way, which will be a keystone of sustainable energy policy. We will need to institute three main objectives to reduce greenhouse gasses and localize power production to facilitate smaller, efficient local power plants.
Why not combine a flexible thin film photovoltaic module with a high performance coating, in effect creating a monolithic membrane system consisting of the coating and the photovoltaic both waterproofing the roof and generating renewable energy.
Take electricity from the sun, run it through a charge controller and into a large battery bank. Have an inverter pull that power out of the batteries (when needed) and make it available as pure sinewave current. The trick: do all this inside of an enclosed trailer.
The Kyocera Solar Grove' consists of 25 Solar Trees' with 1,400 Kyocera KC187GS solar photovoltaic (PV) modules interspersed with 200 translucent KC88CGS modules offering improved daylighting and aesthetic appeal from both above and below the structures.
I think the PV industry will TRIPLE in size in the next 4 years and I think the Thin Film segment of the PV industry will increase over TEN FOLD in the next 4 years.
It is unimaginable to me that a technologically advanced civilization would readily commit environmental and economic suicide when we have most of the necessary clean tech tools already developed. Not effectively leveling this cost comparison playing field now is one step closer to that potential unimaginable outcome.
It can be concluded that the USA is on its way back to the frontline of the global PV industry and market developments. With new upcoming markets not only in California, but also in other US states and countries like Spain, Italy and Greece, a further growth of the global PV market of at least 30% per year for the coming years seems likely

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
