- Q:Can I build my own Hot Water Solar Panels?
- I worked for a plumbing service that offered hot water solar panel installs and replacements. I've replaced perfectly good solar panels for people who wanted to upgrade to the latest. We had piles and piles of panels out behind the shop. We use to scrap the copper and sell the glass panes. A few people would ask to scavenge panels and the boss would let them have it cheap, just to move some of the stuff. I would do the same. I'd find a local installer and see what they do with the leftovers. Chances are, if you searched diligently, you could probably find panels in good shape and use them to supplement your energy usage. Bear in mind, solar hot water system are very different from standard systems. They usually have a much larger storage tank. Typically 80-20 gallons compared to 40. They have a circulating pump and temperature sensors to move the heated water from the panel into the tank. These larger hot water heaters/tanks have much better storage and insulation to keep the water temperature that is generated during the day to last into the evening when people are home to use the shower and wash clothes to take advantage of solar heat. It's not just a matter of getting a panel and slapping it up. There's are technical aspects that need to be followed and if you don't know them, I would advise against doing it yourself. Study up on it and see if it's something you want to tackle on your own before you go too far doing legwork to find out details that might be cost prohibitive or too complicated. Good luck.
- Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
- Low cost solar panels are also extremely popular worldwide and China is a country that has been discovered to be excelling in this field as they manufacture the most economical solar panels when compared to any other country. Looking at the way things seem to be moving it seems that China will soon become a country to contend with because of their capabilities to manufacture things at extremely competitive prices. This fact is quite transparent for the simple reason that China appears to be getting more than double the number of orders. This can also be attributed to the fact that in spite of their low costs they have not only maintained but also improved on their quality too. For More Information You Can Refer To :
- Q:Hi trying to learn more about Solar panels!?
- Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
- Q:how fast does a 25watt solar panel generate power to a battery?
- how fast? what does speed have to do with? Electricity travels at close to the speed of light. A house requires kW at a minimum, and 2 to 5 kW at peaks. You can do the division, 5000/25 = 40. Plus, solar panels operate only 4 to 8 hours a day in the winter, so you need to multiply that number by about at least 6 to allow for the dark hours. .
- Q:SOLAR ELECTRICITY PANELS DO THEY WORK?
- Sure they work, photovoltaics. Light goes in, electricity goes out. Is it a good idea? Well. See, they're expensive. You probably need several kilowatts of capacity to run your house for one thing, and that's going to require several thousands of dollars worth of panels. And electricity doesn't cost that much. You can figure out how long it would take you to make the expense back. It would be a while. It would take even longer if you wanted to spring for a system that could take you completely off the grid, that would require banks of deep cycle batteries too. But most people are probably fine with a system that ties into the grid, and depending on who your utility is you may be able to sell surplus power back to them. Expense is the main reason I think you don't see a huge number of people adopting photovoltaics yet. Doesn't explain why solar heating isn't more popular though. That's really cheap and practical by comparison. But yeah you can find the photovoltaic panels for sale all over the place. Google it. Yeah the going rate for panels is around 2 bucks a watt.
- Q:how does solar panels save energy?
- I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G
- Q:Finding the output of a solar panel?
- You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
- Q:Life expectancy of LEDs and Solar panels...?
- LED's 6 years or longer
- Q:How solar panels and furnaces work?
- Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
- Q:Can I plug a solar panel into a wall socket to lower my electric bill?
- The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.
