product description
The polysilicon manufacturing market is growing rapidly. According to Digitimes, in July 2011, the total polysilicon production in 2010 was 209,000 tons. First-tier suppliers account for 64% of the market while China-based polysilicon firms have 30% of market share. The total production is likely to increase 37.4% to 281,000 tons by end of 2011.For 2012, EETimes Asia predicts 328,000 tons production with only 196,000 tons of demand, with spot prices expected to fall 56%. While good for renewable energy prospects, the subsequent drop in price could be brutal for manufacturers. As of late 2012, SolarIndustryMag reports a capacity of 385,000 tons will be reached by yearend 2012.

- Q: So, I've seen cheap solar panel kits for sale from Harbor Freight, and regardless of whether or not I were to buy a set from them or someone else, I was wondering what the process of implementing a small-scale solar system into your household electrical system would be.I've read articles that started out too in-depth or were speaking of systems on a much larger scale.Can it be as easy as buying the panels and inverter, and plugging it into a socket, or is there more to it?Some of the articles I was reading had mentioned having to contract with your electrical supplier, having to have an electrician tie it all in in some special/ necessary way, using a battery pack (would this be necessary for a tied-in system?), or using the system to only power single items, like a water heater, or plugging items into a connected battery-pack, all of which I'm not sure is necessary or needed for what my goals/ means are/ would be.
- Grid tie inverters are expensive, but you might find a used one cheap on E-Bay, Crags list. Almost any grid tie inverter will work as you are thinking low power, but it likely needs to be 50 hertz or 60 hertz, which ever you have, and 230 volts ac or 20 volts ac which ever you have. It will work for a range of dc voltages, so your solar panels need to produce voltage near the center of that range. I considered buy the 3 PV panel set of 5 watt panels that Harbor freight sells. but I did not determine if the three panels can be conveniently connected in series to produce about 50 volts at light loads, or 00 volts if you buy two sets. You probably do not need the load controller, that comes with each set. I think most grid tie inverters automatically adjust to the dc voltage you supply them, unless it is below some minimum such as 50 volts. It is illegal to connect ordinary inverters to the power company, but they will probably not notice a small system unless you burn your house down. Most inverters will phase lock with the power companies frequency, but they are not designed to do that, so bad is likely unless you connect a resistor such as 0 ohms at 00 watts in series with the ac out of the inverter. If the resistor smokes you should disconnect promptly, then try again to see if you can get phase lock quickly. No smoke, likely means you are one of about 000 co-generators on the electric grid, You can short out the resistor with short piece of very fine wire which will hopefully melt if something goes wrong, such as the power company not sending electricity for 0. seconds or longer. Nearly all inverters have an over load feature, so the thin wire is a back up. Please be careful as people sometimes don't survive an electric shock at 20 volts.
- Q: How much does it cost to replace a solar panel?
- The cost of replacing a solar panel can vary depending on several factors such as the size, type, and quality of the panel, as well as any additional installation or labor costs. On average, the cost can range from a few hundred dollars for a small residential panel to several thousand dollars for a larger commercial panel. It is always best to consult with a solar panel installer or supplier to get an accurate estimate based on your specific needs and requirements.
- Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true)
- Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
- Q: I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!
- There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
- Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.
- A solar panel to charge a 2V battery has 36 cells in series. This allows for temperature of the panel up to 60°C, and the maximum required charge voltage. For a 24V battery, 2 panels in series. A 24V battery requires around 28-29V, but look up your battery data sheet to be certain. A specialized converter using electronics could charge a 24V battery with a 2V panel. The system voltage is controlled by the battery unless the battery is faulty. The 2 panels in series could be 42 volts no load, but the battery pulls this down to whatever is required by the battery. This is because the panels are a current source, the current is determined by illumination, and attempts to draw more result in reduced voltage. Even a short circuited panel delivers approx. the same current with no voltage. The battery voltage varies from around 20V (really flat) to around 28V (really charged). A 30W panel is around .75A, considering the optimum panel voltage for power is around 7V for 36 cells. This is small compared with what you are using. The battery wastes about 30% of the power, in chemical conversions. The time to charge it is 4h at the 0h rate, which is Ah/0. (i.e. ampere hours)
- Q: When you consider that solar panels will not produce enough electricity in their service life to cover their cost should we subsidize them anyway? that much of the cost of a solar panel is the energy to manufacture, install, transport and maintain them. Shouldn't the market determine whether they are worth installing?Is subsidizing them taking money away from research that could be spent on more viable alternatives?Should we be taxed to pay for others solar panels when they don't work?
- Yes, okorder /... Bottom line is that government subsidies encourage people to buy solar panels, and make it possible for many who could otherwise not afford it. The more solar panels are purchased, the more the price will go down, and the more quickly the technology will be able to advance.
- Q: 3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts
- Batteries will not stop charging on their own. The will stop charging when the battery voltage equals the supply voltage. Solar panel open circuit voltage is typically around 20V. Batteries will just boil dry before reaching 20V. One rule of thumb, above 0W you need a controller for sure.
- Q: Can solar panels be installed on bridges or highways?
- Yes, solar panels can be installed on bridges or highways. In fact, there are several projects around the world where solar panels have been installed on bridges and highway infrastructure. These installations not only generate clean energy but also utilize underutilized spaces, contributing to sustainable and efficient use of resources.
- Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
- Given identical panels the one closer to the sun would generate more power, but a difference of only 0 km at 93 million miles, the difference would be very small. Light intensity is inversly perportional to the square of the distance from the source.
- Q: Can solar panels be used for powering a hospital or healthcare facility?
- Yes, solar panels can be used for powering a hospital or healthcare facility. Solar energy can be harnessed through photovoltaic panels to generate electricity, which can be used to meet the power demands of various medical equipment, lighting, heating, and cooling systems in hospitals and healthcare facilities. This not only helps reduce reliance on traditional energy sources but also provides a sustainable and eco-friendly solution for powering critical medical infrastructure.
