Q:I have a question about solar panels?
Read this link.
solar panel absorb sunshine , and it will produce electric charger, the charger move to one direction, it wil produce electric current, so it produce electricity. the electricity can through cable move to solar battery to store or to country power grid to provide electricity for people using.
Q:Solar Energy - What would these solar panels power?
60 Watt Solar Kit 60 watts not much. Max. Power*: 60 Watts Voltage at Maximum Power (Vpm): 6.7 V Current at Maximum Power (Ipm): 3.30 A 0 or 20 of them plus inverter plus battery's not real viable I think how much energy was used in the manufacture of the cells,unfortunately a long way to go
Q:cost of solar panels?

Q:What exactly is a solar panel?
they are a long way from producing enough electricity to keep a cell phone charged. but maybe some day in the future. but as our culture is recognizing the importance of solar electricity they are starting to mass produce solar panels and creating major problems of wast when they get old and stop producing electricity. they are super toxic and shouldnt be thrown away. they will prob have special places set of for those in the future.
Q:Solar panel technology?
It isn't really that simple. First you have to decide if you are going to use it after dark and in cloudy weather. If so you are going to need batteries to store power. You are also going to need an inverter to convert the direct current, low voltage power to 20 volt alternating current. Once you have made those decisions you need to determine power requirements. Look at the back of each piece of equipment and find the wattage rating for the device. Add them together and you will have a starting point for power consumption. Since you will want to charge the batteries during daytime and you have parasitic drain from the inverter use you want to increase that number by 50%. When selecting the number of panels you want you have to assume they will not operate at the optimum they do deteriorate over time so de-rate them by about 50%. Once again, look at the data plate to determine wattage and get enough panels to meet the power requirements using the criteria I have mentioned.
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:Benefits of Solar Panels?
No matter where you live, home solar panels can be installed by professionals. There are also Solar Home Kits you can put into place on your own for less money. You can convert any type of home or business into one that uses solar energy in order to create electricity. Even if you don’t collect enough sunlight for all of your electricity, you can collect enough of it to significantly reduce what you do use. This is one way we can all help the environment. Before you buy solar panels, you'll need to do your homework. Find out what all of the benefits to you are going to be. In addition to helping the environment when you install home solar panels, you'll be saving money on electricity as well. If you are worried about the cost, find out if there is a tax incentive in your area. There should be a rebate or discounted cost offered by the government to entice people to put solar panels in place. Many construction companies are being able to take advantage of them as well. As long as the new homes they build feature solar panels, they can get some great tax breaks. Unsure about the prospect of installing your own home solar panels? That is understandable if you haven’t taken on such a project before. Yet the process isn’t going to be difficult. You can accomplish it with basic tools and several hours of your time. There are some great videos which will walk you through the process.
Q:SOLAR PANELS (sun enerjy)?
Grid-tied solar systems in the U.S. run at least $8/watt installed. To completely run a 2,000 sq ft home, you'd need about 50 amps service from solar -- both 20 volts and 240 volts. Not very practical. Panels are expensive, but the BOS (balance of system) is as well. You need mounts to bolt the panels to the roof (same thing if ground mounted). Cable, wire, and connectors will run several hundred dollars. A couple of grid-tie inverters in the range of 4,000 watts each will cost you several $6,000 to $8,000, plus sub panels, combiner boxes, breakers, disconnects, charge controls, and batteries, among other things. You'd likely need 5 to 24 panels, depending on too many factors to mention here. You'd need at least 8 batteries, likely 2 volt ones, probably more if you want to run the entire home from solar. Solar (or wind) systems have to be installed in the U.S. by state licensed installers, and there are not many of those yet. And if you grid-tie the system, you'll need to put an interconnection agreement in place with your local utility, plus the utility will have requirements on the net-metering and installation of a switch they can use to turn your solar system off from the grid. And this would not produce hot water in the way you are thinking. If you have an electric hot water heater now, the solar system could help run that, just like the rest of your home. Hot water from solar and electricity from solar are two completely different technologies.
Q:how many solar panels do I need for my house if in average i consume 880 kwh?
First, okorder.com/... Second, as a general rule of thumb, you can generate at most 00 watts of power (.Kwh) per 2 square feet of roof space. I have had to revise my own estimates after building a solar array in my yard using high grade solar panels. Solar panels do not put out their peak rating all the time. NOTE: I am not paid nor given any compensation by solar interests.
