Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

Q:Why solar panels are expensive?
Believe it or not, solar panels are so expensive in this country because of government subsides. Without market competition, companies have no obligation to compete with each other on price. If our government would stop paying people to buy solar panels and giving solar panel companies tax breaks, companies would be forced to lower their price and raise their quality in order to get you to buy their product. This would be true of oil/gas, corn, soy beans and a number of other companies and products as well.
Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
Those answers are partly correct. You cannot recharge two 2 volt batteries in series with a photovoltaic panel with an open circuit voltage of 8 volts. You possibly over charged your 7.5 AH battery with a 00 watt photovoltaic panel, which can supply 8 amps to the battery with unusually bright sun light = fully charged in one hour. More likely you did not charge the battery for a month or more which killed it. Also discharging below 2.6 volts shortens the life of the battery, or short circuiting the terminals even briefly. Yes a deep cycle sealed lead acid battery rated 2 AH is likely the best unless you buy a 00 amp hour marine battery which weighs about 80 pounds and will take at least two days of bright Sun to fully charge.
Q:How does a solar panel turn sunlight into electricity?
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
They can be if you are well educated and skilled in their assembly and working functionality, provided you obtain the same high quality grade cells and do proper assembly. Chances are good however that your first several may be just a little below par until you really get the hang of it and become well practiced just as the professionals are. Does take a considerable amount of grunt work however so figure if this is best use of your time or if you'd do better to earn at your regular work and pay a professional to do that which they do best.
Q:electronics help solar panel?
[] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
Q:how does solar panels save energy?
Solar panels doesnot work on electricity.They absorb solar energy emitted by sun and thus work without the usage of electricity.If we use them then there will be automatically reduce the elctricity bills as we dont need to switch on.They use natural source to switch on for which we don't need to pay.
Q:Will my 8watt solar panel charge a car battery and how fast?
How about wind power? Check out this site, you can build one for under two hundred and get free batteries.
Q:can solar power panels installed at home provide enough electricity to power house hold appliances?
During daylight hours yes. I have just six panels, and during the summer, with feed in tariffs paid by my retailer, I hardly pay any electricity bills. Many people around me have up to 20 panels on their roof, and are gross feed in to the grid, meaning no more electricity bills. * or preferably 0 panels will ensure you never have to pay an electricity bill again.
Q:Composition and function of solar panels
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Can I power up 2Watt bulb using 2Watt solar panel power?
Unlikely - at least not a full brightness. You have to match voltages. If your panel is 2v at amp, it won't run a 20v bulb that runs at /0 amp. You're also going to lose power in the wiring and other components that means the 2w panel won't really deliver its full rating. And I'm also guessing that the 2w of the panel is only under full, bright sunlight, so any lessening of the light; clouds, haze, fog, dust, will lessen the power available.
