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:I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
- i think that they are effective, even tho they cost heaps to get installed, i think that they are worth it. They dont require any effort to operate and use natural sunlight that turns into energy that people use everyday. they may be an eye sore but think of how much they are helping the earth and they are a great alternitave to fossil fuels (which are running out anyway), the only problem that i think they would have would be in winter when there isnt much sun on a few days. but other than that they are great
- Q:I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q:What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- well the main problem is that the the solar panels are ineffecent due to their 5 lays(that is what i hunrd they are useing in Gemrnay). Also if i remember right we are at a 20% conversion rate on solor panels. their is 2 problems with solar panels. the weather they drom in effeceny everytime the a cloud get in the way of the sun. what are u doing to do when it gets dusk time? tho neucler power is a good idea. it is only good for the Base load not for the peek power times... IE; Quiting time when everyone gets home and flips on the AC. The best thing really would be Geothormal, nucluer, wind and some solor. but that is for the west out word.. the south is still SOL. So they would need bio fules, better coal plants and fuel cells. (witch is where i am going to start working on here soon )
- Q:Do solar panels require a backup generator?
- No, solar panels do not require a backup generator. They generate electricity from sunlight, so as long as there is sufficient sunlight, they can provide continuous power without the need for a backup generator.
- Q:The voltage and power problems of solar panels
- In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
- Q:Can solar panels be installed on a small scale?
- Yes, solar panels can be installed on a small scale. In fact, they are highly adaptable and can be installed on rooftops, balconies, or even small plots of land. This makes them a convenient and cost-effective solution for individuals or small businesses looking to generate their own renewable energy.
- Q:How do solar panels convert sunlight into electricity?
- Solar panels convert sunlight into electricity through a process called the photovoltaic effect. When sunlight hits the solar panels, the photons in the sunlight excite the electrons in the solar cells, allowing them to flow and create an electric current. This current is then captured and converted into usable electricity, which can power various devices and homes.
- Q:How much is the cost of solar panels including installation for my home so that I can have low monthly power bills.
- You can start as small as 7,500. It all according to how much you want to run off solar and your Environment. You can move into Solar slowly as the technology Improves every six months or so.
- Q:I am doing a science fair project on solar panels, and I need four solar panels to conduct the experiment. I would only need the solar panels for a week. What type of solar panel should I get?
