FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

Q:How can I run my house purely off of solar panels?
It is not feasible to do everything with solar panels. However, if you overproduce during the day and sell the excess to the power company, you might be able to [pay for what you have to buy from them. Another thing you can do is use renewable energy in other forms, with windmills, hydraulic rams, and trombe walls.
Q:should i get a solar panel?
I think solar panels benefit people a lot,it is worth buyingsolar power can be converted into heat energy and electricity which be used into daily human life,more convenient and safe,Also,solar power will not discharge any polluted gas,it can protect our earth.As for the negative,the price of solar power is a little higher at first pay,but you will not pay any fees any more.
Q:How much does a solar panel cost?
2,000 that we have used 4 project , its based on the cell size
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q:How does a solar panel charge controller work for batteries?
7 Amp Solar Charge Controller
Q:How to make 2V 4.5A solar panel from solar cells?
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q:Using a solar panel to make energy?
Small solar panels produce almost no power that matters to anything. A whole square meter may produce 80 Watts when facing the noon sun in Arizona. take that down to 28 Watts in Erie Pa. The 80 Watts can charge a 2 volt battery at about 8 amps times 6 hours, or 48 Amp hours per day in Arizona or perhaps 5 amp hours/day in Erie. The amount of energy you can save declines as the battery is more charged so you need to use up the power stored before you have more to save. To do that charging you need a circuit that will carry 8 amps, including a voltage regulator. So, if your circuit can stand 20 amps the person in Arizona can run 2 square meters of panel. It may seem strange but the same is true for the person in Erie. The person in Erie has to allow for the maximum output of the panel, not the expected average. The person in Erie will occasionally have really clear skies and put out maximum rated amps. The amperage that the batteries can put out at maximum should not be used. That will destroy the battery. One puts a breaker on each output circuit to protect the circuit and a breaker that limits battery output to 20 amps based on a battery rated at 800 amps. That 800 amps is surge capacity. One or two panels does not really justify having this capacity for battery and circuitry. I can think of using it to provide an emergency LED lighting system.
Q:solar panels disconnected from battery?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
