Q:Properties of solar panel?
Q:How can you get affordable Solar Panels?
We are having solar panels installed this Friday. Call a company called Solar City. You can work it through them 3 different ways, you can buy them out right and reap 00% savings, or lease them (like we are) and sign a contract. You won't pay a dime to lease them but your savings won't be as much. The plus side is, you don't have the huge expense either and they are responsible for the maintenance. Lastly, you can lease as the latter option, and purchase during any point of the lease at a pro-rata cost. You can also chose to buy the panels cheaply when your lease is up, but they may be very outdated by then. We have found Solar City top notch, highly trained, extremely polite and considerate. We found them set up at Home Depot. It took from about last January, I think it was, until this Friday, for installation, and then it will be about another 6 weeks until the service is actually turned on. Government red tape, etc. Good luck. I hope this helped.
Q:80 watt solar panel ? what dose that mean?

Q:how to know the voltage level of solar panel?

Q:having problems with my homemade solar panel....?
5.3V is the open voltage or? So the full wattage of the photograph voltaic panel is 45W or so? i assume you are able to no longer make all your small A/C home equipment into DC ones. so which you would be able to think of bearing directly to the 2V DC enter 00W inverter. this type of inverter might have a some bit extensive enter voltage variety from like V-20V some situations.
Q:Anyone who knows or has Solar Panels?
My sincere advice is forget about using a solar panel in your place. It is not suitable for your type of place.I am using three solar panel in my house. One is 30 watts driving an axial flow fan giving very good air for me and for my family people during day time. Another one is only 5 watts. Giving air for my face alone when I work on my lap top.Another 3 watts Panel I am using to determine the life of Panel that drives a mini motor for all the day time from the past 4 years.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:know about solar panels?
Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
Q:solar panels, help?
This is pretty much an exercise in knowing units and dimensional analysis. Watts are in Joules/second. So every second a square with the area(meters^2) of meter^2 receives 380 joules from the sun. In your case the square is the solar panel. So find the area of the solar panel in m^2. If you multiply area times intensity you can see that the meters cancel out and you are left with Watts(J/s). Since you want the Joules received in an hour you again multiply by how many seconds are in an hour. Leaving you with joules. What you have now is the total energy, but your solar panel is only 26% efficient, so just multiply by .26 and you will have your energy.
Q:Questions about charging batteries via solar panel...?
Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
