Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
Q:Wanting to add solar panels to my home?
you need to read and ? your elect co they will help you with survey of your elect use and how to lower bill . for free also read about solar panels and how to use and install bg makes good panels but panels only small part of cost invertor and controler and batterys bigger cost the real expense is panel and controler for panels to to grid connection as per nec is very expensive more than 2 for most 00 or 200 amp service you would better to change to demand type warer heater and flouresent lights and upgrade isullation depending on how you heat house and your area heat pump etc but call your elect co for engergy survey
Q:do solar panels have to be in direct sunlight?
You're going to suffer a loss of output if you do.  How much depends on your exact conditions. Standard window glass (which I assume you want to use) loses light through both absorption and reflection.  It also retains heat.  Silicon PV panels use special low-iron glass (without the green tinge) to minimize absorption, and some have anti-reflective coatings.  They also lose output as the temperature goes up, and a window in front will retain heat. If your panel is behind a window with panes, it may suffer a serious loss of output due to selective shading of some cells in a string (the panel needs all cells in light to produce electricity). So yes and no.  You can put a solar panel behind a window and it will work, but not as well (perhaps very poorly); how much you lose depends on the particulars.
Q:How much does a solar panel cost?

Q:where do you get little solar panels?

Q:Why do glass covers improve the efficiency of solar panels?
Clear glass will allow most of the electromagnetic energy of sunlight into the air-tight volume of the solar panel. The light strikes the black coated metal tubes and the black coated backing, and is absorbed as heat. Part of this heat will radiate as infrared radiation, and much of this will leave through the glass. But a great deal of it will initially remain in the metal as heat. This heat will be partially transferred to the surrounding air, but because the glass stops the mixing of this air with the rest of the atmosphere, this heat will stay mostly contained within the solar panel. If the glass were not there, there would be a huge loss of heat into the surrounding air.
Q:How do you make a solar panel?
It's pretty basic, but I hope this helps!
Q:harbor freight solar panels ?
Yes -- don't buy them. They are low quality solar panels, and the e-z kit they sell produces barely enough power for a lightbulb. The kit they commonly sell is a good child's science fair experiment/project, but do not expect to get your money's worth in solar power. If you are attempting to self-teach yourself on solar panels, this might be a good starting point, if not also a little expensive. But again, do not purchase Harbor Freight solar panels, or their e-z kit. If you are serious about getting into solar panels, there are distributors who will gladly talk to you about what kind of solar panels you will need for a regular house (hint: it is actually a pretty big set of solar panels for even a low power usage home).
Q:How to make 2V 4.5A solar panel from solar cells?
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q:Is heat a factor in how much energy is gained when using solar panels?
Nope. Sunlight is.
