Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
Q:Why do solar panels produce zero energy?
Hey Cosmic, forget about Wayfare and Jenny here, but I have to say your question is a bit vague. When you say the panels produce near zero, how near? Are you using a watt meter, ammeter, or some other sort of metering device. Solar electric, or photovoltiac panels are made almost entirely of silicone wafers. Same as computer chips, when they get hot, the resist the flow of electrons. This is why most panel manufacturers advise installers to upgauge wiring if the temperature falls below 40 degrees F (5C) regularly. Below 0 C, you have to upgauge 2 wire sizes. A good quality panel will put out 50% of its rated power in very cold climates, so it stands to reason that they will put out substantially less in hot weather. Many people think places like the SW United States is great for solar because it's always sunny. In Las Vegas for example, they have 27 sunny days a month, and in August, the temperature frequently reaches 50 degrees C (20F) so people with photovoltiac panels are not even getting half their rated power on a good day. I'm not sure this is what you are asking about. Our home has been powered by the wind and sun for 2 years now. In the summer in the upper midwest, the days are warmer of course, but also much longer than in the winter. So our batteries will frequently fill up by 2:00pm, and the charge controller will taper off the solar charging the rest of the day to minimize overcharging. If you were to check the meters at 3pm, you might notice only 3 or 4 amps coming in when the array is rated at 42. This is normal for us in July and August. These are some reason why a solar array produces near zero in the summertime. Take care Cosmic, Rudydoo
Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:Need Help, 2v Solar Panel for Emergency?
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
Q:Need isntructions for solar panel diy?
Q:How do you make your own solar panels?
If you're thinking of solar electric panels then forget it. It you just want to dabble in solar power then shop around for a 5 volt panel. Find out how many watts it puts out and then divide the cost $$ by the wattage. The lower the cost per watt the better of a deal you'll be getting That's generally speaking of course because it doesn't take quality into account but it's a practical way to compare panels. On the other hand, it you want to make a solar panel that will heat hot water then it's a different story. You can have a lot of fun with that project and you'll find a lot of plans on the Internet.
Q:How do Solar Panels work, and how it can generate electricity?
Solar under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
Q:Help with Home Solar Panel System?
I think this will help you a lot. :)
Q:what do i have to study to install solar panels?
boots on the roof is one of the classes , around phoenix it it offered at rio salado college, there their so theres a place to start. I have had 2 different people check for me and from what i understand i can install the panels but a licensed electrition has to connect to the meter
Q:how do i fix my solar panel? please hurry i need it for my science fair project?
If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
