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:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
What kind of panel are you talking about? Solar thermal, as in for hot water/room heating? Or photovoltaic? In the end its a matter of how good your DIY skills are and from what level of DIY you are talking about. eg, if you are buying the panels and installing them yourself, then there should be no difference. If you are fabricating the panels then you better be good at what you do. Creating photovoltaic cells is not a simple task. Soldering purchased cells together to create panels is tricky as they are easily damaged. Efficiency should not be a problem, but finish might be as well as robustness. It would be safer to buy complete panels and just mount them yourself and set up the batteries ans switch gear. But use good gear and follow instructions very carefully. With thermal panels you might not get the same levels of efficiency by using cheaper materials, std glass instead of non reflective for instance, but if space is not an issue, then you can get more heat out by going bigger and still save overall.
Q:Cost and energy generated by solar panel?
A little more than 0 watts per square foot, so that size panel would generate 250 watts under ideal conditions, which is noon on a sunny but not too hot day, near the equator. That's about /3 horsepower, or the same power as a man working hard. That is larger than needed to keep the battery of the car charged, unless you plan to run a laptop or something off it at night. The power is also too small to power the car for driving. If it's an electric car, you could get maybe another 2 miles per day out of the car, again, under ideal conditions. An RV store might have an idea of how much installation would cost. They would be accustomed to solar panels for RV's, but probably not small cars. A panel of that size would cost perhaps $500-800 just for the panel.
Q:Do I need to run a ground form my solar panel?

Q:Why won't my solar panels drive a motor?
Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
Q:Is getting solar panels worth it for your home?
It strongly depends on where you live. In California or Hawaii, for example, solar can be cheaper than the power company, even without subsidies. Any incentives you get just make it better. Whatever you do, like any construction project, get 3 bids from different companies. If there are not 3 companies in your area, you are probably in a poor location for solar. Avoid any company that does a hard sell and tries to get you to commit immediately, or makes you uncomfortable in any way.
Q:Solar Panel House?
U can get solar panels on OKorder stores rather online or else where on yahoo store online and u have to put the solar panel on every spot on the roof.
Q:solar panel inverters?
definite, the inverter ought to pull potential from both the battery and photo voltaic array, yet so what? that would favor to not be a project. both the potential from the photo voltaic array receives kept contained in the battery, or it is going on to the inverter, what vast difference does it make? in reality that's more beneficial effective to pass on to the inverter, as battery value/discharge cycles waste quite some potential. yet you desire a fee controller between the panel and the battery and which will regulate the present into the battery to maintain away from overcharging, and also regulate the voltage and contemporary to right value the battery. without it, the output from the array will be too intense for the battery, or too low. .
Q:What do I need to install a 40 watt solar panel?
Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
