Q:solar panel for 2 batteries(2 V)?
0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.

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:How much does a solar panel cost?

Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q:Solar Panels in Abu Dhabi, UAE?
Abu Dhabi Solar plant Shams will be completed by the end of this year and will be ready to provide Abu Dhabi with power at commercial prices. Construction began during [the third quarter] of 200. The project's cost is $600 million (Dh2.2 billion) and with its completion, it will be the largest solar project in the world, Yousuf Al Ali, General Manager of Shams Power Company told Gulf News. Once completed, Shams will be one of the largest concentrated solar power [CSP] plants in the world, extending over an area of 2.5 square kilometres with a capacity of approximately 00MW and a solar field consisting of 768 parabolic trough collectors, Al Ali said. He added: Shams is a joint venture between Masdar (60 per cent), Total (20 per cent) and Abengoa (20 per cent).

Q:Solar Energy Panel VS. Energy Efficient Bulbs?
get a voltage tester and test the output from the panel if it is a 24 volt output which is then inverted the reading should be that of the inverter. however if you solar panel installer installed an LCD panel that controls the electricity you can monitor any faults from the panel. Make sure that the panel you feel is not working is producing the same amount of electricity as the others. As for the bulb buy a new one from a different make and see what happens but by testing the output voltage and power you are bound to find the fault.. I have just thought of this the panels supply electricity to big batteries that then distributes power to all the house perhaps the battery supplying power to your room is faulty or the connections to the inverter might be faulty. BEST option if you can afford it because it will be expensive is to buy a solar monitoring system that control the panel and batteries you can even connect it to your laptop and control all the power.
Q:How about solar panels?
A big problem with your theory is that because the solar panel is so small the amount of energy gathered from it would be small and probably wouldnt be able to provide electricity for things and even if it did it wouldn't last very long. its a good idea but it just won't work. in order to produce the amount of energy your talking about the solar panels would have to be the size of a roof and be placed on the rooftop or a hill or something. people wuldnt be able to carry that around.
Q:Do solar panels steal sunlight from nearby plants?
solar panels don't literary attract light but when the light hits it it turns into stored energy planets dont give of heat or ray if u mean stars like the sun yes. it doesn't have anything to do with planets its star noble gases that stuff u can steal light it just gets it other than wasting it solar panels are better than those factory thingys
Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
