Q:Why do solar panels produce zero energy?
Solar panels are a little like batteries or christmas lights, they are often connected in series, if something is wrong in a string of them, current simply won't flow just like how all the lights in some christmas lights go out if one bulb goes out and you have to find the bad bulb by replacing bulbs one at a time.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
how much does these pannels way and which are the most efficient?

Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:Solar panel for your home?
These are all good questions but they are open Items. Solar panels work by the reaction of certain elements upon exposure to sunlight.The amount of power generated is Dependant on at least three factors; The size of the solar panel, the type of solar cells used (The specific element and the cell construction) and the amount of sunlight to which the panels are exposed. The answers to these questions may indicate how much you will save (How much does your electricity now cost per KWH and how much do you use in the two family house} and if solar is feasible in your location. You should probable contact at least three of the local companies that do solar installations and listen (with a cynical ear) to their presentations. They are all trying to sell you their product but you after listening to more than one presentation can sort through the BS. Also you might contact your present power provider. They should be able to give you some good advice on alternative energy availability. Good Luck DOCSRG
Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
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 Panel, what is the catch ?
Sh*t is expensive. I live in FL.....to solar a 500 sq foot house here ...even with the gov rebates and the discounts..etc..etc...costs the home owner @ $24,000 dollars. They say you will recoup your $$$ in 0 years. 0 YEARS??? The gov should get behind this and make it cheaper...but that will not happen.
Q:South facing solar panels?
You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
