ok solar power.....?
those solar power things how do they work - i know they use the sun and store up power and all but im trying to tell someone how they work and are used and how they store up solar power by using the sun. how should i explain it? also what are the solar power things called?

They are called photovoltaic cells. They don't store electrical energy, they generate it.
Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. For example, the current can power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.

Solar Power in layman's terms.
The sun shines on a solar panel these are what you see on roof tops and in back yards. These solar panels (no need to go to the atoms and protons or elements here) create DC electric same as in your car battery. The solar panels are normally hooked to a Charge Controller. A charge controller is a regulator like what is in a car as well. It charges the batteries with the DC electric from the solar panels keeping the batteries from over charging. And the batteries are where the electric is stored. Next you have what is called a Power Inverter which is what changes the DC voltage from the batteries to 120 volts house electric.
Solar Panels, change the suns light in to DC electric.
Charge Controller, controls how much of the DC electric the batteries get.
Batteries, store the electric.
Power Inverter, changes the electric from DC electric to AC house electric.
You can get a better explanation at the link below as well given in layman’s terms.Source(s): http://www.oynot.com/solar-power.html

The potential energy from the sunlight is converted to electrical energy by the use of semi-conductors, but the storage of the electric energy requires batteries or some other storage device. So this is one limiting factor on the use of solar panels -- they only produce electricity during sunlight. The way around that of course is the use of a battery bank that feeds the stored electricity back into your circuits at night and on cloudy days. This technology has been available for quite awhile, but the main obstacle limiting solar's wide-spread adaption has been the high cost of the panels and other equipment in relation to the low cost per month of grid power.
But I have found a company that will rent you all the solar panels and do a complete installation and maintenance for the same amount you pay the utility. There is a performance guarantee and a fixed rate for up to 25 years. That means that as the utility rates keep going up, your electric bill will stay the same. I think it's a brilliant idea. Let me know if you want the company website. email@example.com

The chemicals in the solar cell cause one end to have more electrons than the other end. This is called an electrical potential. It can be compared to lifting a weight off the floor and putting it on the table. It has the same potential energy as it took to lift it to table height. When you push it off the table the energy is released as it hits the floor. In such a way the energy from the sun creates the potential energy between the chemicals in a solar cell. Then it is stored in a battery which holds the energy like the table held the weight.Source(s): Taxigringo

Solar power is economically feasible in some areas.
You can use photovoltaic cells to change light in electricity.We use one on the boat to keep the batteries charged.
You can use black water filled tubes to absorb heat and distribute it to the house or even to make steam for electricity. There are other fluids used too.
We had a black tube air filled system that blew hot air into the house and gave great assist to the regular system. It was enough in spring and fall and aided in the winter on those nice sunny cold days.
In desert areas they are producing electricity for cities, Many areas have solar collectors facing south(northern hemisphere) collecting heat for the house and hot water,Many photovoltaic cells are operating for research stations.
Electric energy is stored in batteries. Heat energy is stored in a material that absorbs heat well. Any of them can be called solar collectors.

solar power means sun's energy. solar devices use sun's energy to do different tasks.
There are mainly two types of solar devices
(1)they convert solar energy into electricity, eg-photovoltaic cells
(2)they concentrate the amount radiations falling on them at one certain point and raise temperature at that point, eg-solar cookers
the solar concentrators are concave mirrors. They are kept facing towards the sun. When sunlight fals on them, they function as mentioned above.
Such devices are used for various tasks like cooking food, heating water and even in power generation.
Installing a solar cooker at home would help you in many ways.
We should more and more go for solar energy. It a non polluting, non ending, eco friendly and reliable source of energy.

solar power. the energy of the sun is captured by storage Celle's smiler to your Avery day battery. the heat from the direct light from the sun is the source of the electric that's being stored

image voltaic Panels are not my forte. however the hardware interior of a working laptop or laptop takes around 3 hundred-4 hundred Watts of electricity at it somewhat is terrific. uncertain what the fee is that batteries fee at, yet for which you're able to examine with the producer. utilising image voltaic panels to fee laptops is a brilliant thought, many human beings purchase laptops particularly to stay away from spending a brilliant form of money or additional money on computers. So even image voltaic panels that are greater or much less no longer portable could nonetheless have many makes use of. or basically construct the image voltaic panel into the video reveal with a splash unfoldable foot that is used to stand it up? you're directly to a minimum of a few thing. nonetheless one element i spotted whilst rereading what you wrote is which you incredibly desire it so it may shop the battery charged whilst working the laptop. element approximately laptop batteries is that, whilst they stay completely charged for long classes of time, they lose their means and that they do no longer final as long. So in case you have been to hook it up, you're able to desire the image voltaic panel to give up charging the battery whilst it fills up and allow the laptop use the battery till it drains it.

still not economically feasible
