The Science of Solar: Solar Energy - The Basics
Solar is one of the most talked-about alternative energy sources in the world today. Enough energy comes from the sun in one hour to power the global population for a year. Even though the amount of sunlight varies around the world, sunlight is a totally renewable resource, unlike oil, coal and natural gas. As long as life exists on the earth, sunlight will play a role.
AltEnergyMag Interview - Dupont's PV Strategy for 2010
Marc Doyle is global business director, DuPont Photovoltaic Solutions (DPVS). He is responsible for creating business strategy for DuPont within the Photovoltaics (PV) market space, coordinating activities across DuPont in the PV industry to create a singular market-facing business, and aggressively growing DuPont's business within the PV space by identifying and championing new business opportunities in white space areas.
AltEnergyMag Interview - Bio-based Solar Cell Backsheets
With over two decades of engineering, marketing, sales and executive management experience in high technology, BioSolar, Inc. Chief Executive Officer Dr. David D. Lee founded the company in 2006. An electrical engineer, Lee recognized that historically, manufacturing costs have been one of the biggest barriers to driving down the cost per kilowatt of solar energy for consumers. In response, BioSolar was the first company to introduce a new dimension of cost reduction by replacing petroleum-based plastic solar cell components with durable bio-based components derived from renewable plant sources.
The Next Generation of PV System Ownership: Moving from Passive Monitoring to Active Management
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-Gen Thin-Film Solar Technologies: Forecasting the Future of Dye Sensitized and Organic PV
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.
N2SOLAR - SIMPLE APPROACHES TO COMPLEX PROBLEMS
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..
SEAN BOURQUIN - CARMANAH
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.
SOLAR PHOTOVOLTAICS MARKET POTENTIAL
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?
GRID PARITY FOR PHOTOVOLTAIC ENERGY
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.
EarthToys Interview - Sun Run Electricity Package
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.
EarthToys Interview - The Community Solar Program
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.
The Nature of Grid Tied PV
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.
Creating New Application Solutions for Building Integrated Photovoltaics (BIPV)
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.
Mobile Solar Power
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.
Parking in a Solar Grove
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.
