Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:Can a solar panel work with an inverter?
Solar panels output a very small amount of current. Even though you're getting 2V from the panels, you aren't getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter. Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 2V source must be able to deliver 20W of power regardless of voltage. In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator. Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel's output rating, then it can power it directly, provided you have 00% light input into the panel.
Q:Who created the first solar panel?
The first photovoltaic cell was developed at Bell Labs in 954. The team included G.L. Pearson, C.S. Fuller, and D.M. Chapin. A panel is composed of many cells. They respond to a wide range of wavelengths, not just UV.
Q:Why aren't electronics made with solar panels?
Well if these things come up with the solar panel than no one can easily but it even run it because solar panels need constant light energy from the sun which consumes in their resources equipment. By the way these are very small things we should think about big like electricity generation still done by coal which is main reason for spreading pollution but now USA is planting solar panel plant which will help to reduce pollution and saving bills money.
Q:how many solar panels will i need?
you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
Q:how much solar panel power do i need?
Buy a device called a kill-a-watt to measure exactly how much power you use. If you get a systemt to put out 000 watts, it's going to be more than you need, and you'll waste your money. 20 amps is 2200 watts (assuming a 0 volt circuit), which is even more. That will be very pricey. Get the kill-a-watt so that you don't spend more than you need to on solar panels. The cost of the kill-a-watt is almost nothing compared to what you'll be spending on the panels. If I had to guess, 500 watts would run all those devices at the same time.
Q:How do you connect solar panel?
If that 55-watt panel has an open circuit voltage of 7-8 volts, you may get more efficiency by omitting the charge controller completely, and connecting the panel straight to the battery. 55 watts is marginally too small for a 200 AH battery at 2 volts, by the way.
Q:What are the benefits of solar panel heating?

Q:How to amplify current from a solar panel?
The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.
Q:What is the most efficient solar panel?
Most Solar Panels are roughtly 6% efficient. Since the sun gives out about 366 watts per square meter, a good panel would be 200+ W/square meter. If you want to save a bunch of money, I suggest you have a look at this tutorial I'm linking. The guy explains how you can assemble your panel yourself. It's far easier than I first thought !
