Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar 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 365 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.

- Q: We are considering getting solar panels for our home just south of Birmingham, AL. We know a little and are trying to educate ourselves the best we can. But we are having a hard time finding anyone around this area. We have done the yellow page thing, and some quot;green places around town. But to no luck.....
- Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
- Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?
- You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
- Q: I want to build solar panels for my house.Dose anyone try okorder is this really work?
- Build okorder
- Q: How much candle lights is required to operate a 205 watt solar panel?
- That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
- Q: can solar power panels installed at home provide enough electricity to power house hold appliainces and heat water.
- Yes, but people usually balk at the cost. Right now, the photoelectric materials are rather expensive. So, most people figure it is not worth spending thousands of dollars and will gladly pay hundreds of dollars a month to the electric company. Most estimates are that it takes at least a year and a half to two years to recover the cost of the panels by how much one can save on their electric bill. Most persons would rather pay out that money in little increments to the electric company instead of all at once when having their home built. Just a side note of trivia: The ability of certain materials to turn photons of light into electric current or the photoelectric effect is what Einstein was awarded his Nobel Prize for, not Relativity.
- Q: What are the maintenance requirements for solar panels?
- The maintenance requirements for solar panels typically involve regular cleaning to remove dirt and debris, as well as ensuring that they are not shaded by nearby trees or structures. Additionally, occasional inspections for any signs of damage or malfunction are recommended, and if necessary, repairs or replacements may need to be carried out by a professional. Overall, solar panels are known for their low maintenance needs, making them a cost-effective and sustainable energy solution.
- Q: Okay, I think I understand what I'm doing, but I want to set up some solar panels on the roof of my garage, the building that gets the most sun, and I want to make sure all my math is correct in determining number of megawatts per year. However, my knowledge of electrical terms in quite n00bish, to say the least.Here is what I think I should be doing.The solar cells come at .75 Watts average power.I will install 4 panels of 64 cells each, with a total of 256 cells.
- For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
- Q: I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?
- Mitsubishi panels have served us well for 3 years so far, no problems. Kyocera had a well-known problem many years ago, but they lived up to the warranty and replaced defective panels. Their current products are considred good. I like the value delivered by Suntech panels. Might be a best buy - shop around. I have not heard about any of the major brands having trouble, lately. If you're intending to connect to the grid, be cautious about used or blemished panels. While they might work fine, they usually are ineligible for rebates.
- Q: Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.
- There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)
