Q:How to charge a Battery with Home Electricity and Solar Panel together?
No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
Q:Solar panels...??? HELP!?
Solar panels are primarily used to make electricity. What you choose to do with this power is up to you. New solar technology now looks to give the panels more than this one task. For example; - solar panels made into the shape of roof tiles can also be used for roofing. - thin film solar is being developed to add to cars and other mobile devices to provide portable DIY energy
Q:What is the difference between Photovoltaic Panels and Solar Panels?
Solar panels collect energy from the sun and then provide it to a system that typically concentrates it. Solar energy comes to us in the form of heat and light. Photovoltaic panels take the light energy from the sun and convert it to electricity. Although the maximum efficiency is around 42% in the lab most commercial models you will see are from 8 to 22% efficient. Adding collectors together concentrates this energy into usable amounts. Solar thermal panels are from 60 to 80% efficient. They come in many different types and collect the heat energy from the sun. That heat may then be stored in some form of thermal mass where it becomes concentrated sufficiently to be used. Solar thermal panels can be used to heat a medium. This can be a phase change material, air, or water. Solar thermal air panels are cheap to make and offer a quick pay back period. Solar thermal panels for some heating and hot water systems circulate water. Vacuum tube collectors are solar thermal panels that may heat water directly or a phase change materials. They can operate better in cloudy and colder weather with more efficiency. Air and water panels are often called flat panels as a way to contrast them with vacuum tube collectors. Solar thermal panels often lead to some form of energy storage called thermal mass (water tanks, phase change materials, masonry walls and rocks.) Photovoltaic panels make electricity that is stored in batteries, used or sent to the general grid. Panels are only one way to collect solar thermal energy. Other types of collectors are used commercially and are often called simply solar concentrators. Some are called parabolic trough collectors and parabolic dish collectors.
Q:Can You Choose Between Solar Panels And Aircraft Fuselage Report?
Fuselage, solar panels are boring...check out the design considerations for the fuselage of the old SR-7 Blackbird, a really amazing aircraft in its day.

Q:How are solar panels developed and distributed in America?
The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
Q:What are solar panels made up of?
Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
Q:Do solar panels go bad if not used?

Q:Where can I find low power solar panels?
My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
Q:Solar panels and distance from the sun?
you are right , the solar painel higher in the atmosphere , gonna receive more solar warm , your friends are totaly wrong ,
