Q:how many solar panels?
dozens at a huge cost which only run in sunlight so not ideal for running lights, solar panels are just not economical or reliable, probably around $5000?
Q:Solar panels and your opinion?
Solar power is still an expensive way to purchase power, as of 2007, it was 38 cents per kwh while the cost of power from coal is 0.6 cents per kwh. Of course regulations have prevented new coal power stations from being built so it's really natural gas power stations at 5 cents a kwh that solar has to compete with. Solar is dropping in price but the best you can hope for is for it to reach parity with natural gas someday soon and it hasn't yet. The other issue is that you pay up front for solar power which as any economist will tell you is even more expensive and involves greater risks. However, as part of a strategy to become as self reliant as possible when you retire and have a fixed income, it's a reasonable prospect, not only will the technology become less expensive by then but at that point, fixing the price of the energy costs is more valuable than the cost of the energy. Focusing on personal finance and learning how to invest which very few people know how to do is more important right now. When you retire, hopefully you can afford to build a passive solar home with photovoltaic solar panels and wind turbines but still on the grid for efficient net metering and with a greenhouse where you can grow the staples that you need and perhaps even some biodiesel for your google driven car. Having a reasonable portfolio is really the only way to achieve that goal.
Q:electronics help solar panel?
[] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
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:Have a question about mobile homes and solar panels!!!?
I was in debt up to my eyeballs, and I needed help fast, so I looked to some free online programs. I had tried so many that were scams, but I finally found one legit one! In two months, I paid off $3000 of my debt.
Q:Solar Powered Propeller?
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q:How do you make solar panels?
It's possible to put together pre-made solar cells into your own panels, but the result will be far less durable, and more costly than simply buying commercial panels. You may encounter some websites offering to sell you information on how you can power your home cheaply with homemade panels. Every one of those I've seen is a scam. Save your money. Do you need a lot of panels to make electricity? To make a system that is worth it generally takes at least a dozen panels, although I'm sure exceptions exist. Also, it generally needs a professional install to meet legal requirements, although a few skilled homeowners do manage to do their own.
Q:How to maintain a battery with a solar panel?
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
Q:Solar Panels Have Faded?
Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
