Poly-Crystalline solar panel, Poly 156 cell, 60pcs.Power range 230W-260W.
Solar panel refers either to a photovoltaic (PV) module, a solar hot water panel, or to a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q: What are solar panels?
- The solar panel is that convert sunlight into electric. There are two kinds of solar panels, poly solar panel and mono solar panel.
- Q: The first panel is located in New England, the second is placed in the Sahara desert, the third is on the Earth side of the moon, and the last is on the far side of the moon. Which panel would absorb the most sunlight over a year's time and why ? All the panels are place in optimal places where they would get the most light available.
- Well, as always, context is important. Sunlight is composed of a lot of different types and wavelengths of energy, and our atmosphere and magnetoshpere filter out a certain amount. If the question is actually which solar panel would produce the most energy (which I assume it is), we would have to look at how solar panels work. There are three different classes of solar panel function. Photovoltaic cells convert sunlight directly into electrical energy, but most systems are pretty low on efficiency. Solar cells can be used for generating heat, through boiling water or some other liquid frequently. And solar panels can be used to produce chemical reactions, breaking down solutions into ions, for example, and the breaking of the molecular bonds releases a certain amount of energy. So theoretically, the two sides of the moon get the same amount of solar energy, just at different times -- about 6 months of the year or so. If the solar panels were thermal energy panels, the ones on the Earth would do much better, because the moon is so much colder. The weather is the most convincing argument for comparing the Sahara and New England. New England is likely to be more cloudy and polluted than the Sahara. Since the Earth probably eclipses the moon a bit more often than the reverse, there may be a little more visible sunlight that gets to earthly solar panels, but the ones on the moon would get a greater proportion of the sunlight (more wavelengths, for example), so it would be close. The Earth eclipses only the near face of the moon, so that would give the far side of the moon a slight edge perhaps. I'd guess it would be the far-side lunar one, but too many variables to be sure.
- Q: My house is aligned exactly North-South, so I have no roof facing South. Is it worth installing solar panels? Are there any good options for dealing with this situation?
- The answer is NO. We can install PV solar panels to properties that are South East – South West facing. Of course it helps if you are 00% South facing but it’s not the end of the world. In fact I would say that the majority of solar panel installations across Britain are not 00% South facing.
- Q: Is there a cheaper way on how to make your own solar panels ? Can someone share their real life experience ? Thank you.
- If okorder / . Beware of anyone who makes claims you can save tons of money by making your own panels. Those are scams. It's possible to save money with solar, but not with homemade panels.
- Q: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???
- There is no such thing as a megawatt per hour. Watts aren't a unit of energy, watts are a unit of power. Power is the rate at which energy is converted. Power is to energy as speed is to distance. Watt-hours or the famous kiloWatt-hour are units of energy. Also the Joule is the more scientific unit of energy.
- Q: I have to get a lot of information on how solar panels are developed and distributed in America because I have to do two pages on this. Please help me get information in this I really need it!! Thankss...
- The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
- Q: Can solar panels be used for powering outdoor signage?
- Yes, solar panels can be used to power outdoor signage. Solar panels convert sunlight into electricity, providing a sustainable and renewable energy source for outdoor signage. This eliminates the need for traditional electricity sources, reduces energy costs, and minimizes the environmental impact.
- Q: How much space is required for installing solar panels?
- The amount of space required for installing solar panels can vary depending on factors such as the size and type of panels, as well as the energy needs of the property. However, on average, a typical residential solar panel system requires about 100-400 square feet of roof space per kilowatt of installed capacity.
- Q: how does solar panels work?
- Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
- Q: So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
- You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
