Q:How much do solar panels usually cost?
Solar panels are currently selling for between $4 and $6 per watt of rated power output. A typical panel that you might install on your roof would be rated for between 00 and 300 watts and therefore will cost between about $400 and around $500 or so. A complete solar power system also needs some other components and will have some installation costs and so the total installed cost of a solar system is typically in the range of $8 - 0 per watt of rated power. Most home sized systems are rated in the 000 to 0,000 watt range and therefore cost between about $8000 and $00,000 dollars to install. Many states offer rebates and tax savings that can reduce this cost by as much as 50%. These systems will typically generate between about $300 and $2500 worth or electricity per year. Solar panels are expected to last between 30 and 50 years and so these systems will likely generate between $9000 and $20,000 worth of electricity over their life time in current dollars. This will vary widely though based on local electricity costs and may well increase greatly in the future if electricity rates rise.
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:Numbers behind Solar Panels?
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:Build your own solar panel, scam or truth?
What I've heard, is that for those sites implying that you can power your house and save money with homemade solar panels, is that if you try to get your money back, there is no response. Maybe if you used a real credit card, you could dispute the charges through your credit card company. Actually, I wouldn't be worried about buying materials and it not working - the more likely scenario is that you would get their instructions, and realize that they're practically worthless. In Florida, you have a chance to save money on your electric long-term, but it will be by investing maybe $0-20k, and then getting that back after 0 or more years. I'd suggest you contact a local solar installer and get a bid, even if it's only to scope out how much it would cost up front. Then you can shop around and see if you could save by installing it yourself. It's a serious project, not to be taken lightly. It took me about 3 months to put it up. It's possible that you will not save money by self-installing, as professionals may get better prices on the panels. The Florida state rebate is subject to availability of funds, and typically, I've heard people wait a long time to get it. The Federal rebate is a credit to your taxes, so you get it the next year.
Q:Solar Panel load resistors?
Look at the graph data that looks like a rotated L. That is what voltage as a function of current characteristically behaves. The highest voltage value is called open circuit voltage (Voc). The current at lowest voltage value is called short circuit current (Isc). If you notice, a second curve is plotted that looks like a hill. That curve is power output as a function of voltage. At the peak of said hill, you get the most utility of your PV module, as you output the maximum power possible, and that is the nameplate value for the PV module's power rating.
Q:Can A Home Owned Solar Panel Support The Entire House's Electrical Needs?

Q:Benefits of Solar Panels?
The solar panels that we all simply would think are the greatest thing ever are very, very expensive and require strip mining of huge areas of land to make. For several million dollars you can buy what usually is mounted as power source for space satellites upon your roof. This 2'x2' panel and a barrage of battery storage takes care of all the electrical needs you could ever have at home. But this profoundly environmentally destructive technology is not what you had in mind, I'm sure, but is what has been around for quite some time now. It's been a challenge to make solar panels without using complex chains of excited rare metallurgies, but we seem to be getting better and better at it--but I trust others should help you with the practical, now that you know the best panels are not best for us at home.
Q:know about solar panels?
Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
Q:can solar panels be refurbished?
Often they get scrapped out or landfilled. Photovoltaics cannot be refurbished. Solar collectors for heating air or water, could be concievably refitted with new clear covering, new insulation, and new heat exchanger, but unless it was a custom installed system you are trying to refurbish, it is more time economical to construct new ones, or to buy new ones.
Q:Solar Panels for home use?
Solar is a system, not just panels. Here is a link to the pro's that do this daily. You need to do the inside of your home, before you do the outside. Only then will solar work for you.
