Characteristics of Polycrystalline Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology. .

 

Standard Test Conditions of Polycrystalline Solar Panel

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions of multicrystalline silicon Solar Panel, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

 

Q:Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.
Connecting them is not a problem: the solar cell has two leads or terminals, and so does the motor. The problem is that the panel from the calculator cannot supply very much current, and you need quite a bit for the motor. Also, the voltage is probably not more than 3 volts, and the motor needs probably six to twelve volts. If you have a voltmeter, check the output from the solar cell. You can get solar cells that will put out more current, but they will be bigger than the ones used for calculators. Even with these, you will probably need several in series to get enough voltage for the motor.
Q:All I want to power is a small ice-maker (250 watts) for 25 minutes per day. That's all!!!Can I do that by using a 00 watt panel with 2-3 deep cycle batteries and getting 0 hours of quality light per day.(BTW) what size converter would you recommend? I want more than I need to grow the system

Q:Are there any government incentives or tax credits for installing solar panels?
Yes, there are government incentives and tax credits available for installing solar panels. These incentives vary by country and region, but they often include federal tax credits, state or provincial rebates, and local grants or loans. These financial incentives aim to promote the adoption of renewable energy sources and help offset the initial costs of installing solar panels. It is advisable to consult local authorities or renewable energy organizations to learn about specific incentives available in your area.
Q:Can solar panels be used in areas with high temperatures?
Yes, solar panels can be used in areas with high temperatures. In fact, solar panels are designed to withstand a wide range of temperatures, including high heat. While excessive heat may slightly reduce their efficiency, modern solar panels are equipped with cooling mechanisms that help maintain their performance even in hot climates.
Q:Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?

Q:the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.
It may be that the power output of your solar panel is not enough to drive the DC motor. It is producing up to 6 volts but it may not be producing many milliamps. LEDs need very little power to work but DC motors often need quite a high current to get them turning. If you can run several solar panels in parallel, you can probably increase the available current. Alternatively, can you expose the existing panel to much more light so as to get it to work at its maximum output? That might work. Good luck with your science exhibition.
Q:What sort of maintenance is required for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q:Can solar panels be used to heat water?
Yes, solar panels can be used to heat water. Solar thermal systems, also known as solar water heaters, use sunlight to heat water and are more efficient at heating water compared to using solar panels for electricity generation. These systems capture the sun's energy and transfer it to a fluid, which then heats the water for various applications such as domestic use, swimming pools, and commercial purposes.
Q:Can solar panels be installed on schools or universities?
Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are taking advantage of solar energy to reduce their carbon footprint and save on energy costs. Solar panels can be easily installed on rooftops or open spaces within the campus, providing clean and renewable energy for various electrical needs of the school or university.
Q:I have a solar panel i got for free and I don't know what to do with it. Its kinda big at about 20x 0and it puts our 2 VOC / .23 ISC. I don't know of anything that I could use it for. Its too big to say charge a phone or ipod....any suggestions??
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
