Q:Properties of solar panel?
Q:Need Solar Panel Guru.....?
Basically, the answer to your question is forget it. Your approx 8 tons of AC will require about 28 KW of electricity just to run them. Add the rest of the house requirements and your talking a load of 50KW or more. Even if your state has a subsidy program, (and most of them are out of money now), it's a $200,000. system. Making your own panels would be a mistake. Reliability and survival are the key measures for a panel system and homemade panels are just not going to be reliable enough to survive the cold winters. In the end, it is always cheaper to buy good, conservatively rated commercial panels, especially in view of the fact that prices have been tumbling lately. Often, the mounting, interface and conversion costs are greater than the cost of the panels themselves. You might save some bucks by fabricating a mounting framework yourself and installing it, but such a system would not qualify for most state programs and.... you had better be an expert architect or engineer to put together something that will work well. The basic problem after all of this is that your maximum demand will be at night and the panels put out nothing at night. Better to forget about a 00% solution. You can install a modest 0 - 20KW system for perhaps $50,000 costs after rebates and subsidies and perhaps ... it might cover about /4 of your energy needs and might just, pay the investment back in 0 to 5 years. Get first rate equipment and professional installation, if you want the system to perform reliably. Solar voltaics make a lot of sense for Arizona and perhaps Florida. For anyone north of the Mason Dixon line however, fossil fuels are cheap, reliable and work far better.
Q:Solar panels and your opinion?
The payback is usually between about 5 and 5 years depending on how expensive electricity is in your area, the rebates available, and where you live (is it sunny most of the time?) Most people that get them don't do it for the investment - they do it to be energy responsible - but it's not a bad way to do both if you have the money to put into it. I personally just pay for the green energy option from my electricity provider. So I am buying power from solar and wind farms, and it cost about 0% more per month. I don't get the benefit of free power, but it comes with a smaller price tag initially, and I think when we all invest in these technologies, the price will improve over time, so energy costs will be lower in the future.
Q:Solar Energy Panels, a good idea?
Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
Q:How do Solar Panels work, and how it can generate electricity?
Solar okorder.com under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
Q:Can You Choose Between Solar Panels And Aircraft Fuselage Report?
Solar Panels. Solar panels is a generic term for any semiconductor that converts solar energy to electrical energy. However there many different kinds of solar panels and constructed in different ways from different materials. There is the generic polysilicon solar panels for residential installation on one end of the spectrum. On the other end are very high efficiency (and expensive) solar cells used on the Mars Orbiter that are constructed of so called triple junction GaAs/Ge solar cells. In addition there are also the thin film solar cells that are being researched that use Cadmium Telluride (CdTe) to form junctions and make very efficient cells on very thin substrates. I would say that research into materials that can be used for solar cells is one of the hottest research fields right now. (That being said, I really did enjoy Airframe by Micheal Crithon. Whenever I'm in a plane during bad weather I always thing of the engineers that designed the plane... what assumptions did they make... what tradeoffs did they make... )
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
Q:What do I need to install a 40 watt solar panel?
Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
Q:Does a 50W solar panel generate 540kWh?
your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .
Q:Solar panel connectionI
The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.
