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:Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks
I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.
Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?

Q:I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
Q:a) i'd like to get a solar panel to make this thing i saw in popular science, it was a bag that had a solar panel in the side (you just attach it with grommets into a clear vinyl pocket you make. its for charging elecronics and stuff) and i was wondering what kind i should look at, do they come flexible? can i get them on OKorder? what kind of wattage should i look for (btw it also had a little voltage regulator and stuff to make a little usb in your bag) so any info on that!b) i was thinking about like putting solar panels on my roof, where can i look into that, is that a good choice, has anyone done it, how did it work out? thank you, just curious
answering b) your home circutry won't be able to handle solar power energy (or your circut breaker,it will start cuttin out every 5 min)you would have to replace your home circutry(that costs a LOT of money, over $8500)
Q:Hello everybody, the area we are living has energy crises with no electricity available most of the time. What I am thinking is to buy a solar panel with other required accessories. Please note we have normally long sunny days most of the time during a year.Please advice installing solar energy system would supply energy 24/7? I have a television, a dvd player, a fan, 4 energy saver lights (2 watt each) and a laptop. Please also advice the specifications for the system to be installed and the points I need to ensure at the time of purchase. I think of buying a solid battery (not acidic battery)The forum is open for your kind suggestions.Thanks!

Q:Can solar panels be used in deserts?
Yes, solar panels can be used in deserts. In fact, deserts are ideal locations for solar panel installations due to the high levels of sunlight and low cloud cover. The abundance of sunlight in deserts makes them an excellent environment for generating solar energy efficiently.
Q:Ok so i can have a problem i have two 5 watt 2 volt solar panels a 2 volt battery and a 400 watt ac 2 volt dc inverter i believe im only getting 5 watts from from my solar panels thats the equivalent of one is there any way i could get full voltage from my solar panels without theoretically burning my wallet.. please help
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q:who has solar panels on their home and are they worth it
They're only worth it if: # - you are rich enough to afford them over the long term. Commercially installed solar panels will take you over 0 years to see any financial benefit. #2 - you get the parts and some instructions and get them built yourself. DIY or get a local electrician to put them together. If you don't fit into any of these 2 categories, then they're NOT worth it.
Q:Can solar panels be installed on any type of roof?
Solar panels can be installed on most types of roofs, including flat, sloped, and metal roofs. However, the suitability of a roof for solar panel installation depends on factors such as its orientation, shading, structural integrity, and load-bearing capacity. It is recommended to consult with a solar professional to assess the specific requirements and feasibility for installing solar panels on a particular roof type.
Q:Can solar panels be used on agricultural land?
Yes, solar panels can be used on agricultural land. In fact, utilizing solar panels on agricultural land has become increasingly popular as it provides dual benefits of generating clean energy while not interfering with the farming activities. This practice, known as agrivoltaics or dual-use farming, allows farmers to continue cultivating crops or raising livestock under the shade of solar panels, maximizing land use efficiency and diversifying income sources.
