Q:Solar Energy - What would these solar panels power?
For okorder.com As for that kit you are looking at, that is more suitable for mounting on a travel trailer somewhere where you are camping to recharge the deep cycle battery for the low voltage appliances you are using. Right now is probably a good time to start looking at ways of either running on low voltage, say for general lighting in a basement, or shed, and putting up some means of maintaining those batteries with solar and or wind. If you start small, you can add on at any time.
Q:do solar panels have to be in direct sunlight?
Should be okay but you might lose a little power if the windows blocks infrared or ultraviolet light [which I believe they do]
Q:Solar Panel Question?
I like TBS0's answer, but 5KW isn't going to hack it. We don't live life on the average. If you turn on the oven, the dryer, the iron, a bunch of lights, and the TV, you are going to shut the system right down. You should not count on running everything with solar cells, but the most critical circuits. And you are lucky to have 25% of a day in optimum solar alignment for photocells. You need to think outside the Al Gore crazy box. Our modern way of life requires a lot of power! If you switched to coal or wood for cooking and heating and ironing, sunshine for drying clothes, heating the hot water heater, and for daytime lighting, then you could use the photocells for some lighting and the washing machine and anything electronic. You might stand a chance.
Q:how instal solar panel?
There are MANY garden lights with built in batteries and solar panels that you just need to stick in the ground. There are also self contained units that are wall mountable. THAT way there is no need to run wiring, use battery stacks, etc. and will also probably be less expensive overall.
Q:can a small solar panel be charged with lamps?
Sure!...did you ever use a solar powered calculator indoors under a lamp?? It works just fine.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:How can a solar panel work for me?
Sounds okorder.com.. I've seen the particular device listed there. While the lamp is mediocre for an LED light source, the panel is excellent - real polysilicon wafers, in an aluminum frame. Same construction as the kind of panels in commercial installations.
Q:adding more solar panel & battery?
That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.
Q:i want to light up a building using solar panel what do i need?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q:Efficiency of solar panels?
Efficiency of photovoltaic panels usually describes the ratio between the energy of the sunlight falling onto the panels and the electric energy you get out. This number is, for commercially available panels today, usually in the range of 2...9 %. What you are asking is something else. The power from the panel depends on the light falling on it. A panel rated for kw peak will deliver that kw under a clear sky, with the sun orthogonally above the panel. For a fixed mounted panel, that is true (at most) for two days every year at noon. At any other time, the output is less. Therefore (at least for the area I live in), some people build databases (and Excel tools) in which the various variables are considered: - inclination of the panel - orientation of the panel - average sunshine duration during a year Plugging in these numbers, I get theoretically for my roof an electricity output of just over 000 kWh/year per installed kWpeak of collector power. If you set up a tracking panel (following the sun), the energy output of the panel will be higher, but so will be the cost for the mounting and the area needed to set up the system.
