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:0 Watt solar panel question?
Watts okorder.com/
Q:Does making solar panels cause more pollution than they take away when used?
A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.
Q:how to know the voltage level of solar panel?
The voltage rating and current rating are part of the specifications for the panel. You will have them listed on the spec sheet. The voltage number is usually the open circuit voltage of the panel, the voltage with no load. The current number is the short circuit current of the panel. In use, you need special electronics, called a Maximum Power Tracker (MPT) controller, which adjust the load to get the most power from the panel, and adjust the voltage output via a DC-DC converter to the optimal conditions to charge the attached battery. how to take batteries as per solar wattage ? sorry, don't understand this.
Q:What does solar panel power?
I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
Q:Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this?
In Europe the governments offer an electrical buy back incentive of surplus solar electricity but to claim the income the solar panels must be installed by a registered installer who submits details of their skills. The skill to install requires some experience in building/roofing work for which there is no qualification and an electrician to wire up the components to the mains. Electrical engineering courses are available at local tech colleges. If you are just installing a 2/24 volt system you don't really need much experience, it is not syncing a full mains voltage in to the domestic mains! Installing thermal [water] solar uses similar building skills and requires he final fix to be performed by a heating engineer, again the course is available at tech colleges. both plumbing and electrical engineers need to be updated on changes and so there is ongoing education costs and licenses. If you can't afford college [two year +] try finding an employer who will let you work and study part time. There is a lot of demand here so few employers pay for the course but some do. go through your yellow pages and submit your cv to electricians/plumbers. Then when you get qualified learn about solar, and set up your own business. As a builder of sorts! Ive fitted systems and then found a electrician/plumber to do the final fix. You cant beat experience.
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
image voltaic charger employs image voltaic ability to offer electricity to units or cost batteries. they're oftentimes portable. image voltaic array: electric powered gadget alongside with an excellent array of related image voltaic cells image voltaic Panel is a crew of image voltaic cells arranged right into a panel which would be put in onto a flat floor. The panel captures image voltaic and converts it into DC ability.
Q:Sizing solar PV panels?

Q:Do solar panels generate power when it's cloudy?
No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.
Q:If I shine different color lights (bulbs) on a solar panel, will it affect the electricity output?
