Q:Do solar panels add to global warming?
One piece of technology: Hydro-energy storage. Pump water up to an artificial lake at the top of a mountain to store energy, and then let the water run down through turbines to retrieve the energy later, eliminating most or all of the need for batteries. Usually this stuff saying renewables suck is BS when you actually try. Yet another method, are solar power towers which last longer than solar panels and continue to generate energy at night. While a non-universal storage method, it's good for storing the sun's energy in the mechanism that generates the power. According to some studies, they are the best option next to wind turbines. I'll describe a particular model. A field of mirrors beams light to a part of the tower which contains salt, for it's incredible heat storage capacity when molten. In turn, the heat from that region heats water which spins some turbines, generating lots of energy. Currently, the best models continue to generate electricity at night and for a few consecutive cloudy days. I think whoever was saying that was probably trying to delay response. There are too many ways around that to be true, and saying that it contributes more to Global Warming than fossil fuels is a lie. This is why some government intervention is needed: The companies aren't responding to new ideas, and they happen to often be fossil fuel companies as well. If you don't create the environment where it lowers fossil fuel consumption, then they win because prices stay high.
Q:How to charge a Battery with Home Electricity and Solar Panel together?
No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
Q:Can cold light make solar panels power
The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:What is maximum system voltage in solar panel?
System voltage is the total across the full chain of panels, when using multiple panels in series. It's what the insulation on the panel is rated to stand, to earth/ground, without breaking down. A device could have an output rating of V and still a 000V insulation rating. eg. if your 0W panel had an open-circuit voltage of 25V, the insulation is rated to stand up to 40 panels connected in series. (40 x 25 = 000V). And actually a 0W power source could be rated at 000V, if it's current rating was only 0 milliamps. (Though extremely impractical for a solar panel unit).
Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:A more efficient solar panel?
yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
Q:Please explain KW Solar Panels. What does it mean.?
First, learn the difference between kilowatts and kilowatt hours, and all shall be made clear.
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:What type of wires should i use for a solar panel?
Most epoxy is not very conductive. I would go with solder.
