Solar cells also can be used to power outdoor lighting fixtures. Credit: Warren Gretz Introduction to photovoltaic (solar cell) systems Solar cells convert sunlight directly into electricity. Solar cells are often used to power calculators and watches. They are made of semiconducting materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect. Solar cells are typically combined into modules that hold about 40 cells; about 10 of these modules are mounted in PV arrays that can measure up to several meters on a side. These flat-plate PV arrays can be mounted at a fixed angle facing south, or they can be mounted on a tracking device that follows the sun, allowing them to capture the most sunlight over the course of a day. About 10 to 20 PV arrays can provide enough power for a household; for large electric utility or industrial applications, hundreds of arrays can be interconnected to form a single, large PV system. Thin film solar cells use layers of semiconductor materials only a few micrometers thick. Thin film technology has made it possible for solar cells to now double as rooftop shingles, roof tiles, building facades, or the glazing for skylights or atria. The solar cell version of items such as shingles offer the same protection and durability as ordinary asphalt shingles.

Investment in PV my be cost-effective in certain distributed generation and grid-support applications where PV output tends to coincidence with local peak demands. Small stand-alone PV systems have proven practical in many areas of the country where connection with the local distribution was too costly or impractical. Such systems, when coupled with a storage battery, can serve loads such as homes, radio stations, control systems, telephone repeaters and lighting systems. PV modules may be installed in buildings as part of the roofing, walls, and/or windows.

55. History Of Solar Photovoltaic Power And Solar Panels solar photovoltaic information about the history of solar energy and solar panels photovoltaic solar power is one of the most promising renewable energy http://www.solarexpert.com/pvbasics2.html

History Of Solar Power The model for the fusion power plant, the sun, is a source of practically unlimited energy, most of which is wasted but nevertheless provides us with millions of kilowatts of power, keeps us warm, and grows all our food. To top it off, solar energy is safe, pollution-free energy on and in which living things have thrived since they first appeared on earth. Every day the sun showers Earth with several thousand times as much energy as we use. Even the small amount that strikes our roof is many times as much as all the energy that comes in through electric wires. With the sun straight overhead, a single acre of land receives some four thousand horsepower, about equivalent to a large railroad locomotive. In less than three days the solar energy reaching Earth more than matches the estimated total of all the fossil fuels on Earth! The logical question at this point is, Why are we not making use of this incredible bonanza in the form of solar energy? The answer, of course, is that we are using it, and have been from the beginning. All our energy-except nuclear- comes originally from the sun. A solar-powered radio draws on the sun directly, but a gasoline fueled automobile also uses solar energy-stored solar energy, in which the sunshine of ages ago was trapped in the earth until reclaimed by oil drillers. The challenge is to make use of solar energy directly and in a non-polluting fashion.

58. Pacific Solar A company working towards commercialisation of revolutionary new solar photovoltaic (PV) energy technology and systems including film siliconon-glass solar modules to transform sunlight into electricity. http://www.pacificsolar.com.au

Company History Crystalline Silicon on Glass Contact Us Pacific Solar Pty Limited was formed in 1995 as a cooperative venture between the University of New South Wales and Pacific Power, the state's electric utility company. The goal was to commercialise a cost-effective technology for conversion of sunlight into electricity using the photovoltaic (PV) effect. The PV technology, now known as Crystalline Silicon on Glass (CSG), was conceived at UNSW by Professors Martin Green and Stuart Wenham with graduate student Zhengrong Shi. Funding for the first five years of Pacific Solar was provided entirely by Pacific Power. The company was established in suburban Sydney, Australia. In the year 2000, additional funding was provided by Eurosolare SpA, the solar division of Italian company ENI, and in 2003 a final round of funding was provided by the State Government of New South Wales. By this time, Pacific Power's share of Pacific Solar had been transferred to RBMC, a subsidiary of the State Government of New South Wales. In June 2004, Pacific Solar sold its physical assets and worldwide rights relating to the CSG technology to a new German company, CSG Solar AG, which was formed with financial backing from a consortium of European investors. CSG Solar AG formed an Australian subsidiary, CSG Solar Pty Limited, which continues to operate the pilot-line facility built in Sydney by Pacific Solar. When CSG Solar begins producing PV panels commercially, a portion of the sales revenue will be returned to Pacific Solar in the form of royalties and dividends.

@import url(misc/drupal.css); @import url(modules/navigation/navigation.css); Complete Systems Solar Wind Water ... Power Distribution Photovoltaic Solar Power Solar Photovoltaic Power Solar power is one of the first things that comes to most people's minds when the subject of alternative energy comes up. Solar power first gained wide public awareness during the 1970's energy crisis, and while it may not be such a hot topic these days, solar technology has made great advances since then. Solar Thermal Panels Solar Electric Panels Solar Thermal Panels The first widespread residential use of solar energy came in the form of solar thermal heating panels. By covering a system of copper pipes with a black heat-collecting surface beneath a greenhouse-style pane of glass, fluid inside the copper pipes can be heated with solar radiation and pumped through a baseboard heating system, used for household water heating or for heating swimming pools. However solar thermal panels aren't very efficient for applications requiring very high heat fluid. While these systems may be ideal for keeping a small swimming pool at a comfortable temperature, baseboard heating or household hot water would likely require a gas or electric secondary heater. In Alaska, during much of the year solar radiation would not be sufficient to counteract the extreme cold, so these systems are probably best left for summer cabins and more southern homes. Solar Electric Panels back to top Photovoltaic (PV) panels, which use sunlight to produce electricity, are much more efficient for their purpose than their solar thermal cousins. They are also much more useful in northern climates. While the manufacturing process and the mechanism by which they work is more technical than solar thermal, they are much simpler to install and maintain in actual use. Following is an overview of the function and purpose of photovoltaic panels, as well as the many benefits they have in alternative energy systems.

National Electric Code Tip of the Week The code requires that every DC source have a means of being disconnected from the batteries. The code can be satisfied by a single DC disconnect on each array. We use a double pole disconnect wired so that the array and the batteries can be disconnected from the charge controller at the same time. That way, the controller can be completely disconnected for service or replacement. Wyoming Trivia Wyoming is famous for natural wonders like Yellowstone Park and Devil's Tower, but did you know that it was home to Sahara-like sand dunes? The Killpecker Dunes north of Rock Springs are some of the biggest dunes in the United States.
