Q:Can someone please explain to me the basics of solar panels and power storage/usage?
Okay well solar panels only work under sunlight and it saves alot of electricty as compared to your normal switches.And it also saves money=D.One thing though...it only works under sunlight...remember this fact. Power storage simply means a device which can store power. Well a generator stores power and a power station too!! Otherwise they can't flow through our electric current..... So for power usage simply is like on the fan/lights/mobile/computers/modems/e.t.c are considered as power usage as you are using the power=P Well hope this information helps you!
Q:How will i construct solar panel?
The key is like a spiral stair case with landings at each floor, but the momentum of having to turn is enough to climb from floor to floor. I guess the energetics use the handrail quite utterly and only, pressing against it like bearings in a wheel. With metals and metalloids a 3' x 3' solar panel would power your house and car and make your energy bill negative, but costs several million dollars since the chain of rare elements is only affordable to obtain by strip-mining top soil of many square miles of fertile land just for a single panel and thus destroys good farmland for hundreds if not thousands of years. Clearly solar panels will not solve any problems ever...unless their yours only.
Q:Can you get energy at night from solar panels?

Q:harbor freight solar panels ?
I bought my first set 8 years age and the 45 watt set finally gave up the ghost last week. I have another 45 watt set 3 years old and has maintained 4 2 v deep cell batteries at 3.5 to 3.8 volts for the last 3 years. I have them on my cabin and use them mainly for lights and TV. but with my 2000-4000 watt inverter runs the microwave nicely.
Q:How many Watts of solar panels?
Running an oven or stove on solar is not a practicality; too much power is needed, use gas. Ditto, heating using solar electricity is not a practicality, and AC would also be asking a lot. The other things, within limits, might be do-able. You'll be needing as many solar panels as you can fit on. If I was you I'd consult a solar installer about how big your battery bank should be once you have decided how many Watts of panels you can put on.
Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q:Solar panel for laptop?
laptop don't get enough power.
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
Q:5kw Solar Panel Roof Kit?
Note that aiming is important - the sun is going to be perpendicular to the panels for only a few hours a year unless they are on an adjustable mount, so picking the time you most want power should be a factor in the angle they are mounted at - you can't keep the highest level of sun for summer into the winter time when the sun is much lower in the sky for a shorter time.
Q:A good brand of solar panels for my house?
You don't say what you are doing. Are you trying to get electricity from them and need solar photovoltaic panels or are you trying to run a heating or hot water system and need solar thermal panels. It is unfortunate that both of these are known as solar panels as they are really two entirely different designs. Currently the solar thermal panels are more efficient and therefore have a quicker pay back period usually measured in lower single digit years while the photovoltaic panels have paybacks that are sometimes more than double that unless you figure in increased property values and state and federal subsidiaries and tax credits where available. Edit: Recent advances make any current investment in photovoltaic panels likely to be obsolete in 5 years. Still someone has to be on the cutting edge. Two currently available technologies are concentrating the sun's rays within the collector on a much small chip area.2 This improves the efficiency and lowers the cost as concentrators are cheaper than chips. The other option is newer chips that accept a wider spectrum of solar energy.3 This has the potential advantage of producing more energy on cloudy days. This may not be so important in your situation. Balanced against cutting edge technology will be the possibility of getting older panels at a less expensive cost. The bottem line will always be pay back period. More panels at a lower efficiency and cheaper price will be just as good as high efficiency at a higher price if the numbers work out. 4 Between two answers here you now have a criteria for selection and some recomendations. Good luck with your project.
