Q:How many solar panels do you need to power a house?
Here in southwestern Arizona more and more solar panels are getting installed everyday. If it wasn't an economical thing to do I doubt if people would be doing it. Given that because of climate change our summers are getting longer and apparently hotter running an air conditioner gets evermore expensive. Also every year or so the rates go up. At the current rate of increase rates will easily double in a decade. Installing a solar array means that in far less than a decade, given a hefty down payment, any government subsidies and tax breaks in a couple of years you'll own your own electric company. Technically about /4 of the US would benefit from a true government program to install solar panels on all buildings. Years ago it became law that every building had to have electricity, running water and flush toilets. We need a similar law to hurry up a conversion to solar where practical.
Q:What SOLAR PANEL kit do I need?

Q:How many LED's can I hook up to my mini-solar panel?
You need to answer that by designing circuits to provide each LED with its specific voltage and current requirements, and then see how many you can supply.
Q:Why are solar panels only 0% efficient?
Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.

Q:what kind of rays are used in solar panels?
Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.
Q:QUestion about portable Solar Panels.. Mine is 2v?
Your portable panel is at most a few amps at 2 volts nominal.Hopefully you have a higher voltage than this to enable you to charge a 2 volt battery. This takes about 3.3-3.6 volts. Your converter will function until a battery reaches about 0.5 volts (drop out voltages vary greatly). A deep discharge marine batttery will be the best bet for storage but usually more expensive than a regular battery. If your resources are limited, you might try from these cheaper sources. Insterstate battery stores usually have blems at a lower price. These are totally functional batteries but have surface imperfections that the manufacturer doesn't want his name on. Also check you local junkyard or towing service. They are often asked by insurance carriers to junk a car which has been wrecked. Many times the batteries are still perfect. They sell these for what they can get for them. Look for one from a SUV with lots of power options. Often kids cars have outlandish stereo systems requiring heaavy current batteries. These are a good find. Consider getting a solar power management system for charging your system. It will limit your charging voltage so you do not float a 2 volt battery above 4 volts where it would slowly destroy it.
Q:I would like to know mire about solar energy ?
There okorder.com. Building solar panels, none. There are internet sites where you can buy unframed panels to design your own. but you need a current stabilizer and possibly a power inverter to go with it.
Q:Information on making solar panels?
Typical solar panels like Engineer describes require a lot of space. A single panel may only light a single light bulb. You may want to look into a different way of generating electricity with solar, it doesn't use a cell to turn the sunlight into electricity, instead it uses mirrors to focus the sunlight onto a pipe between the mirrors. The heat causes water or another liquid in the pipe to boil and the steam created turns a turbine that produces the electricity. It has the potential to be less high-tech, more forgiving of minor design and structural problems and more affordable. I don't know of any system that is privately available but you can get more info at the link below. They're building a full test facility in Nevada right now. You could presumably cobble something like this up on your own.
Q:Any tips for protecting my solar panel from high winds?
Solar panels are a costly and significant investment. Therefore, protecting them from harm should be a top priority. Unfortunately, moisture and water are common ways for solar panels to become damaged or broken. Safekeeping solar panels from both of these threats is a simple, inexpensive procedure, and doing so might save the solar panel owner a bundle if carried out correctly Instructions : Set a thick strip of silicone between each cell when putting the solar panel together, in order to prevent moisture seepage. 2: Use Plexiglas instead of glass as the face of your solar panel. Plexiglas is less liable to break and therefore safe from hailstorms or accidents. 3: Glue adhesive silicone to each side of your solar panel(s), adding additional sealant and protection from water to your commodity. :)
