Especial: Cómo hacer un panel solar 2ª Parte (Traducción) Solar Cell Kits. Dye-sensitized solar cell. A selection of dye-sensitized solar cells The DSSC has a number of attractive features; it is simple to make using conventional roll-printing techniques, is semi-flexible and semi-transparent which offers a variety of uses not applicable to glass-based systems, and most of the materials used are low-cost.

In practice it has proven difficult to eliminate a number of expensive materials, notably platinum and ruthenium, and the liquid electrolyte presents a serious challenge to making a cell suitable for use in all weather. Although its conversion efficiency is less than the best thin-film cells, in theory its price/performance ratio should be good enough to allow them to compete with fossil fuel electrical generation by achieving grid parity. ICE 98-001 - Nanocrystalline Dye Sensitized Solar Cell Kit. ICE 98-001 - Nanocrystalline Dye-Sensitized Solar Cell Kit Greg P. Smestad, Ph.D. developed a prototype nanocrystalline dye sensitized solar cell kit in 1998, using dyes from plants. This kit can provide an interdisciplinary context for students learning the basic principles of biological extraction, chemistry, physics, environmental science and nanotechnology. The result of the procedure is a solar cell that lasts no longer than a few months, so it is a teaching tool and not a practical photovoltaic module.

It should be noted that the kit and its associated procedures are not to be used without the help and guidance of an adult who understands basic chemical safety practices.

Ahorra en tu factura eléctrica. JHRoerden. Ahorro. La compañía alemana JHRoerden, distribuidora de equipamiento para instalaciones fotovoltaicas, acaba de anunciar el lanzamiento en España de su paquete "Plug & Save" (enchufa y ahorra), una "pequeña instalación de energía solar" que se puede conectar "directamente a la corriente de su hogar ahorrando en su factura de electricidad".

La compañía alemana, que cumple precisamente en estas fechas cuarenta años de actividad, asegura que su kit fotovoltaico "es tan sencillo que lo puede instalar uno mismo". Según JHRoerden, sus soluciones de autoconsumo incluyen todo lo necesario para la autoinstalación "en su terraza, jardín, garaje, tejado o incluso en su fachada, en un espacio de apenas dos metros cuadrados".

El distribuidor germano, que comercializa el paquete básico a un precio de 529 euros, oferta una gama de cinco soluciones fotovoltaicas. La gama de paquetes fotovoltaicos para autoconsumo que acaba de presentar JHRoerden consta de cinco soluciones. Más informaciónwww.jhroerden.com. SOCIEDADE DO SOL. Lessons Learned from Selling a Solar Company to SunEdison. Now that hard installation costs are dropping rapidly in the solar pv industry, everyone’s looking at how to decrease soft costs.

Across the board support for decreasing solar’s soft costs is the result of how well organized the industry is becoming. State governments, the DOE, and private software companies are all working to help. Note: Download A Free Chapter from Keith’s Book Solar Success Principles, or take his “Best Practices in Solar Sales and Marketing”, or apply for the “Solar Executive MBA” course that Keith is teaching. Cost reduction and the commoditization of project financing are two keys to building profitable companies and an industry. However, when the costs fall, financial barriers are eliminated, and policy bottlenecks are lifted, the company that has the advantage will be the one that is uber-efficient on the operations side.

For this reason, I spoke with Keith Cronin from Sun Hedge. We had a great discussion that lasted almost 45 minutes, here’s what we talked about. The Ultimate Solar Startup Guide. Learn How to Start a Solar Company with the Solar Startup Guide. If you’re new to the solar industry, go to the Solar 101 Reading list.

It has free tools and articles on solar design and installation, sales and marketing, policy, finance and best practices. If you need to understand the technical side of residential solar PV design, download the free 60+ page PDF “Solar PV Design 101″ to learn the basic terms, how to estimate array size, power production, size an inverter, and size module strings and conductor size. If you’re going start a solar business, you need to learn how to perform site visits. Performing high quality and efficient site visits is absolutely critical to the success of profitable solar projects, especially residential projects! You need to be able to capture all of the information you need to 1) quote the system correctly 2) design the project and 3) inform the installation crew what to expect. Sunnovations STS. How Solar Hot Water Works [Video]

On average, about 18% of home energy consumption is for water heating, the second largest consumer behind space heating.

Calefactor con latas. Calentador con botellas. One Block Off the Grid. Hybrid solar system makes rooftop hydrogen. While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays.

Instead of systems based on standard solar panels, Duke engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen much more efficiently than current technology without significant impurities. The resulting hydrogen can be stored and used on demand in fuel cells.

For his analysis, Hotz compared the hybrid system to three different technologies in terms of their exergetic performance. Exergy is a way of describing how much of a given quantity of energy can theoretically be converted to useful work. Like other solar-based systems, the hybrid system begins with the collection of sunlight. New System Powers Your Home More Efficiently with Solar-Hydrogen Hybrid Array. A professor at Duke University has developed an innovative solar energy system that powers buildings with hydrogen.

The system, though it looks like a solar array, is made up of thousands of coiled copper tubes coated with a thin layer of aluminum and aluminum oxide and filled part-way with catalytic nanoparticles. A mixture of water and methanol is rushed through the tubes, and as it heats up and evaporates a catalyst is added to create hydrogen. The system is more efficient than any currently on the market, and the hydrogen created can be stored in a pressurized chamber to be used whenever needed.

“This set-up allows up to 95 percent of the sunlight to be absorbed with very little being lost as heat to the surroundings,” said the system designer Duke engineer Nico Hotz. Solar Panel Makin’s. So you’re thinking about making your own solar panels or maybe jumping on board the solar panel making train and going into business crankin’ out the best solar panels in the world.

Never mind the $100million investment in a panel factory or the fact that you are going up against some of the largest companies in the world, you’re on a mission and solar panels are the game. For those that feel the draw of the solar panel siren, the engineers at SkyPower would like to help you by giving you a little direction as to what sort of stuff goes into these bad boys and how it all comes together to make some of modern technologies newest darlings … the solar cell.

Let’s start with the good news … there isn’t really any bad news here. All of these things are available and none are all that expensive. You can hold them in your hands and as long as you don’t heat them to really high temperatures and vaporize them, you can pretty much do what you’d like with them without getting hurt.
