does anybudy know about solar panels? plz reply me
Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×0 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.
Solar Panels are groups of Solar Modules mounted together. A solar cell is one cell. A solar module is a group of cells mounted in to a sheet A solar panel is a group of solar modules connected together on a rack and normally placed on the roof etc.. as a unit and can be called a solar array. A solar array is a group of solar modules or solar panels all mounted and wired together to form a single unit. Like a battery bank is a bunch of batteries hooked together and the batteries are made of cells. Was that what you wanted to know?

See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
