Q:What is the difference between solar panels and light panels?
Silicon solar cells are divided into monocrystalline silicon, polysilicon, amorphous silicon, silicon thin film solar cells and several. At present, the world's most widely used solar cells are silicon solar cells, in large-scale applications and industrial production is still dominated by the penetration rate of 90% or more, monocrystalline silicon solar cell photoelectric conversion efficiency of the highest technology is also the most mature.
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:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q:how to hook up solar panels to meter?
At best, you'll burn your house down. You could quite possibly loose your sight or your life. Let the pros do it.
Q:Need Large solar panels. ?
Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.
Q:Should I buy solar panels?
Without doing any calculations, I would assume that paying down debt would be a better use of your money. Solar panels are only going to get less expensive and more efficient with time so waiting before you invest in solar panels is a good idea. Of course, to properly evaluate the prospects of going solar, you should consider the tax credits available in your state and the promotional value to your business.
Q:Life expectancy of LEDs and Solar panels...?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
Q:What does it mean when a solar panel is 00w?
That means it can handle UP TO 00W at any given time in bright sunlight. Volts x Amps = Watts. This means you can use of these panels to supply a 9 volt DC appliance at amps. Which is a pretty ridiculous amount of amps for a 9 volt product. About 5 of the 65 Watt panels will give you in excess of 825W of power, which will give you 5kWh per day. But, remember that's DC. When you convert to AC, that changes. I would suggest keeping batteries for storage. Also, You might require an average of 825 W per hour, but at any given time, you'll use a higher peak. You need to find out what the PEAK is before you can decide what to get. That would be with all the lights on in your house, running the vacuum, the dryer, and the washing machine. I think most houses are built with 00Amp breakers. That's 2 kilowatts at one time. That would mean you would need 72 panels to be at the PEAK your house can handle. You'll hopefully never use 2kW at one time. But there's no way for me to know what YOUR peak will be. I think the average kW peak demand is somewhere in the range of 2 kW. That would require 3+ panels.
Q:Solar Panel Demonstration Ideas?

Q:Is heat a factor in how much energy is gained when using solar panels?
Not at all. You`ll generate more energy on a clear sunny day in the winter time than you would on a cloudy day in the summer.
