Q:Why are solar panels so expensive?
They are made of costly materials and require expensive manufacturing processes. The market has been limited because people are not catching on very well to the new idea. The more we buy and use solar panels, the more the price will come down.
Q:Solar panels with snow?
Good news and not so good news. You need to be able to access the panels to clean the snow off. There is not any heat generated other than the heat of the sun hitting the black colour - which would amount to some melting ability during a sunny day - but it isn't sunny when it snows! Apparently, solar panels work better in the cold and where snow can reflect light so to increase the amount of light - photons - hitting the panel.
Q:What exactly is a solar panel?
What a solar panel REALLY is is a political rip-off in which the government takes money from me to help you buy solar panels that produce a fraction of the power you could have bought with the money they stole and which required more volatile chemicals to manufacture than would have been created in the consumption of that same power.
Q:solar panels and batteries?
If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK

Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q:Solar Panel Efficiency?
Depends where you live. Each kWp will generate in a year about 750kWh in northern England, or 900kWh in the south. About ,00kWh in the south of Germany or up to 2,200 kWh in the Californian desert. The farther you are from the equator, the bigger the difference between summer and winter months: in S California summer months may only generate 2 times as much electricity as winter months. In the UK it can be 4-5 times as much. 200 W is 0.2 kWp so divide the numbers I gave by 5 and then divide by 2 to get the 'average' month - you really need to look up 'insolation tables' for your area though!
Q:solar panel help needed ?
One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
