What is a photovoltaic system?

Answer 1

Photovoltaic systems are usually Solar Cells that absorb sunlight and convert it to electricity.
Another photovoltaic system uses mirrors to boil a liquid and uses the steam generated to power a turbine. The project in the US failed because the foam insulation decayed and reduced the efficiency of the mirrors. Spain is currently working on their own system (Science Channel’s Eco Tech).
There is a company in California that sells roofing shingle solar cells, so you can use them to power your house as well as a roof. They don’t sell them outside of California though.

According to Wikipedia: http://en.wikipedia.org/wiki/Photovoltaic
"Photovoltaics, or PV for short, is a solar power technology that uses solar cells or solar photovoltaic arrays to convert light from the sun directly into electricity. Photovoltaics are also the field of study relating to this technology and there are many research institutes devoted to work on photovoltaics."

“Solar photovoltaic arrays have capacity factors of around 19%, which is lower than many other industrial sources of electricity.”

Currently solar cells are less than 40% efficient and they need to be improved, one problem is aligning the substructure crystals to get the most efficiency (Popular Science). That’s why we aren’t using a lot of solar cells to power our world.

Hello..... In Solar (Sun) collection the normal way to convert the suns ray to electricity is a photovoltaic system...Lets just explore the photovoltaic part first...It is a thin wafer that is made of mineral silicone cast or cut very thin . this crystal can convert light energy to electrical energy directly.

The system part is were the bulk of the materials are ..In most systems conversion is not enough because the amount converted per second generally does not meet the demand..So people use large banks of Wet Batteries to hold the power(potential) for later use. By arranging your batteries correctly you can get a rate of usage overcome by the rate of charge..With proper control (not to many parasitic) loads you may even have a little to spare. The controllers for this type of system range from just using the voltage produce by the batteries to very sophisticated inverters which can boost the power to higher voltages and change the DC to AC . In many cases one must watch out for inverters as they follow the laws of physics and there is energy lost in conversion...Go to wikipedia.com and look under your special request and there is worlds of info in the web pages...Also good news is out there as they have just discovered ,a few months ago, a material that is much more efficient than the old silicon cell...Good luck with your search...From the E..

"the terrific" relies upon on some components: a million) in case you do not comprehend for the way lengthy you retain dwelling on your place, then pass the main inexpensive. maximum domicile clientele are (nevertheless) not arranged to pay for what you have invested. 2) in case you have numerous money "left over", then choose for an entire-fledged equipment, i.e. with comments into the grid (this is in the journey that your electrical energy business enterprise does that kind of situation, not all do!). reason: Payback era of (excessive) preliminary funding could be decreased. 3) in case you in simple terms opt for to "sense stable to have performed something for the ecosystem", then choose for a smaller equipment that in simple terms components part of your own desires. additionally evaluate that in the time of a few aspects, you will possibly be able to nicely be constrained in what you're able to do (making plans permission by making use of community authority).
