  • Base stations - for mobil and internet provider

  • Polycrystalline silicon, also called polysilicon or poly-Si, is a high purity, polycrystalline form ofsilicon, used as a raw material by the solar photovoltaic and electronics industry.

  • Polysilicon consists of small crystals, also known as crystallites, giving the material its typical metal flake effect. While polysilicon and multisilicon are often used as synonyms, multicrystalline usually refers to crystalls larger than 1 mm. Multicrystalline solar cells are the most common type of solar cells in the fast-growing PV market and consume most of the worldwide produced polysilicon. About 5 tons of polysilicon is required to manufacture 1 megawatt (MW) of conventional solar modules.[2] Polysilicon is distinct from monocrystalline silicon and amorphous silicon.Military and Paramilitary base stations

Q:How much energy does this particular solar panel produce?
It's virtually impossible to estimate how many panels would be required, without knowing your electrical usage, and where the house is located. I'll give our house as an example, but it could be off by a factor of 0 (not kidding) from yours. We have gas heat, no air conditioning, and no pool. We live in a dry, sunny area of California, and our roof is ideally oriented for panels. We would need 25 such panels, but we are grid-tied. If we wanted to disconnect completely from the electric company, we would need 20% more panels to compensate for battery inefficiencies. So, the estimate is 30 panels. Here are some caveats: ) Air conditioning, especially central air, could double or triple the estimate. 2) An area that gets less sun per year (northern US, for example) would need more panels. 3) Typically, when a house has grid electricity, they keep grid electricity when they get solar panels. It's much cheaper to use both in tandem. 4) That's a horrible price for the panel in the picture. You can find a 200-watt panel for less than that. 5) Other equipment is required besides the panels to run your house off solar. You can read up on it on the internet, or ask a professional solar installer for a free quote.
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:How much does 000 square feet of solar panels cost?
Are you asking about solar water heaters or solar electric panels?
Q:Is there any way I can get solar panels with my restrictions?
Nope; I see no escape. Best advice I can give is this: sell out and move to a single home residence that has no HOA. If you want solar, I believe the main roofline should run east-west, so that the south exposure of the roof can be easily and economically populated with panels. APS is better than SRP wrt solar ....maybe. Im not sure, everythiong around here is APS so there's no balance. Ive occasionally heard rumors from SRP folks who are unhappy.... check into it before you buy.
Q:Solar panel, Home office and Tax write off?
5% of the Net Cost (After Rebates) Depreciated over 27.5 years. EDIT: Oops ....39 years. I was actually debated that in my head before I posted.
Q:How many solar panels?
A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
Q:How much Silver do we need for Solar Panels?
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:What is the most efficient solar panel?

Q:help understanding solar panel stuff?
Any fan you find in a store is going to expect AC, not DC, which is what solar panels produce. An inverter changes DC to AC. You'll probably want a deep cycle car battery to smooth out overages and underages. Any fan will tell you how many watts it uses. Panels should (i haven't looked) tell you how many watts they produce. Just off hand, I'd guess you're looking at a 2'x4' panel. Considering how much you'll be paying for the rest of the stuff, a good 00' cord is appropriate,. Last, it's worth the experience, but you'll never recover the cost of everything that you'll have to buy. Have fun.
Q:Why aren't electronics made with solar panels?
Cost and and it would be inconvenient to the consumer in this Gotta have instant gratification society. take the amount of money you paid for your MP3 player- double it- would you still have bought it at that price? That IS what happens when you add in a 2 to 0 dollar component. Besides- the energy required for most items you cite- a solar panel makes it not portable. While you might be able to arbittrarily decide to go without an MP3 player for 24 hours, could you do it for a week? How about your cell phone? It uses more power- so go without it for 2 weeks. You still need batteries to be charged by solar panels due to one major flaw of solar panels- they do not work in the dark. So in effect all you are really doing is weighing the device down with a solar panel, and you still have not gotten away from a need for a battery. I don't know about you, but I have an MP3 player about the diameter of a 50 cent piece- where are you going to put the solar panel??? It will not have enough power to operate the device, and marginal at best for charginthe battery which would take hours instead of the minutes it takes connected to a USB port.
